helping you understand
Tower Dryer Operations & Service
safe operating procedures, and
some of the problems that may
be encountered by the dryer
operator or other personnel.
As owner and/or operator, it is
your responsibility to know
what requirements, hazards and
precautions exist, and to inform
all personnel associated with
the equipment or who are in the
dryer area. Avoid any alterations to the equipment. Such
alterations may produce a very
dangerous situation, where
serious injury or death may
occur.
The GSI Group, Inc. recommends you contact
your local power company and have a representative
survey your dryer installation, so your wiring will be

READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAFETY PRECAUTIONS
Use Caution In The
Operation Of This Equipment
4. Check for gas leaks at all gas pipe connections. If any leaks are
detected, do not operate dryer. Shut down and repair before further operation.
The design and manufacture of this
dryer is directed toward operator
safety. However, the very nature
of a grain dryer having a gas burner,
high voltage electrical equipment and
high speed rotating parts, does
present a hazard to personnel, which
can not be completely safeguarded
against, without interfering with efficient operation and reasonable access to components.
Use extreme caution in working
around high speed fans, gas-fired
heaters, augers and auxiliary conveyors.
5. Never attempt to operate the dryer by jumping or otherwise bypassing
any safety devices on the unit.
KEEP THE DRYER CLEAN
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before trying to operate
the dryer.
2. Never operate the dryer while any guards are removed.
3. Power supply should be OFF for service of electrical components. Use CAUTION in checking voltage or other procedures requiring power to be ON.
DO NOT ALLOW FINE
6. Do not exceed maximum recommended drying temperatures.
7. Keep the dryer clean. Do not allow fine material to accumulate in
the plenum chamber.
8. Keep blower drive belts tight enough to prevent slippage.
MATERIAL TO
ACCUMULATE IN THE
PLENUM CHAMBER
OR SURROUNDING THE
OUTSIDE OF THE DRYER
9. Use CAUTION in working around high speed fans, gas burners, augers
and auxiliary conveyors which START AUTOMATICALLY.
10. Do not operate in any area where combustible material will be drawn into
the fan.
11. Be certain that capacities of auxiliary conveyors are matched to dryer
metering capacities.
12. Clean grain is easier to dry. Fine material increases resistance to airflow
and requires removal of extra moisture.
13. Do not adjust any moving part on the dryer while it is running.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the
owner. For a safe and dependable
drying system, follow the recommendations within this manual, and make
it a practice to regularly inspect the
operation of the unit for any developing problems or unsafe conditions.
Take special note of the safety
precautions listed above before attempting to operate the dryer.

III. Operation Procedure
1. Start the dryer; set the dryer unload at a
desired speed from the dryer control panel.
2. Let the dryer run under manual mode
for warming up until the column grain
temperature has stabilized and the moisture
coming out of the dryer is within ± 2% of
the target moisture.
3. During the start-up period, calibrate
both the wet and dry sensors against a
bench meter as follows:
a) Press “SENSOR CALIBRATION”
button from the moisture control set-up
screen to open the sensor calibration
screen.
b) Take grain samples from the dryer,
measure the moisture with a bench meter
and then compare to the sensor reading
during the sampling period.
Change the sensor offset if the sensor
reading does not match the bench measurement. For example, if the offset was 1.0%,
and the sensor reading is 0.5% lower than
the bench meter, then change the offset to
1.5% to match the sensor to the bench
meter. Likewise, if the sensor reading is
higher than the bench meter, the offset
should be decreased accordingly.
15
TRI-POINT MOISTURE CONTROLLER Tower Dryer Operations & Service
The sensor should be calibrated 2-3 times a
day. At the same time check and clean the sensor
and sensor sampling box to make sure that there is
no debris blocking the grain flow around the
sensor.
4. Check or change the target moisture
from the main screen.
5. Press “MOIST CONTROL” to access the moisture control set-up screen.

PRE-SEASONAL INSPECTION AND
SERVICE
The dryer is made of weather resistant material, and is
designed to require minimum service. However, each
season we recommend the following items be checked
before the unit is used, and any damaged or questionable parts replaced. These checks will help eliminate
possible failures, and assure dependable operation of
the equipment.
1. Shut off electrical power. Open power box and
control box, and inspect for moisture, rodent damage or accumulated foreign material present. Inspect and tighten any loose terminal connections.
Replace any damaged or deteriorated wiring.
2. Lubricate the blowers, motors, and metering system as outlined in the Lubrication Table below.
3. Check blower belts for proper tension.
4. Inspect and clean the burner. Visually check that
no holes in the stainless steel air mixing plates are
plugged. If burner ports are plugged, clear them
with a piece of wire or a drill bit. After a period of
several years, it may become necessary to drill
out the burner ports to clear away accumulated
rust. Use a #43 drill bit to return burner ports to
their original diameter. (See burner drilling procedure in the Maxon Burner area of the COMPONENT MANUALS section of this book.)
(NOTE: Pre-2002 model dryers require a #47
drill bit.)
5. Check electrical connections at both the flame rod
and spark plug. Clean spark ignitor and flame
rod. Replace if necessary.
6. Check drain valve on gas train to insure that there
is no water in the gas train. Valve should always
be open when the dryer is not being used. Insure
that drain valve is closed prior to dryer operation.
7. Lubricate linkage on gas modulating valve.
24
8. On Zimmerman Dryers equipped with the
Accutrol sweep unload metering system, check
the discharge area to insure that the area is cleaned
of stalks and old grain. Inspect the sweeps for
excessive wear.
9. On GSI Dryers equipped with the hoppered
metering system, check the hopper area and the
area around the metering drum to insure that they
are cleaned of stalks and old grain. Check the
edges of the metering drum for excessive wear.
10. Important!! The covers to the discharge
sections on both the Zimmerman and GSI Tower
dryers must be in place and clamped down at all
times when the dryer is in operation. If the cover
is off during operation, the vacuum created by the
blowers will suck foreign matter from the
discharge area and deposit it in the heat section of
the dryer plugging the inside screens of the dryer
also creating a fire hazzard.

7.
Important! The covers to the metering system access door(s) 4.
must be in place at all times when the dryer is in operation.
Before turning blowers always make sure this door is clamped 5.
into position.
Follow lubrication guides as outlined in the Lubrication
Table.
6.
Do not let grain fines and dust accumulate inside the
cooling section of the dryer. Bi-weekly if drying most products or daily if drying milo, clean the cooling chamber floor of
fines and dust. Sweep down the cooling section sheets if
necessary. Fines can be swept into the unload systems on
7.
both the Zimmerman and GSI dryers.
Do not let grain fines and dust accumulate inside the
heat section of the dryer. Daily check the hopper divider
that separates the heat section from the cooling section to
insure that it remains clean and open.
1.
When cleaning dryer, check the grain discharge area on the
dryer. On GSI hopper bottom dryers check around the metering drum to insure that grain is flowing freely from each column and that there is no trash build-up. On Zimmerman
Accutrol sweep dryers check the sweeps for trash or stalk
buildups that could be obstructing grain flow.
2.
If undried grain is left in the dryer for more than a week during
the drying season, inspect the plenum roof to make sure that 3.
there is no wet grain sticking to the roof that could restrict
grain flow. When the dryer is restarted make sure that all grain 4.
columns are evenly unloading.
When drying dirty corn in high humidity conditions, sludge
5.
may build up in the upper outside sheets of the dryer. This
build up can be removed by either washing the sheets down
6.
with a high pressure water hose, or by shutting incoming grain,
dropping the grain level to below the plugged area, and then
running the fans and burner to dry the affected area. Tapping
or sweeping the sheets will dislodge debris. Attempting to
7.
sweep off the sheet build-up while it is still wet will usually
plug the sheet more.
8.
IN CASE OF FIRE
1.
When you first detect a fire, the entire drying operation should
be shut down, including grain flow into and out of the dryer.
The emergency controls may have already done this. Also,
shut off the electrical and fuel supply to the dryer.
2.
Do not try to cool a fire by running fan(s).
3.
Never run grain from the dryer into the elevator or storage if a
fire is known or suspected.
26
9.
Locate the area of the fire.
If the fire can be extinguished with a fire extinguisher, water
hose or by removing the burning material, this should be done
right away. Watch the dryer closely for another fire after one
has occurred.
Emergency discharge slide gates at the bottom of each column
as well as easy access gates located near the hopper discharge
area permit fast dumping of each individual grain column. If it
is necessary to emergency dump grain from the dryer, wait
until the fire department is onsite before doing so.
A fire extinguisher should be located at or near the dryer, if a
fire seems to be getting out of control call the fire department.
END OF SEASON SERVICE
Empty the dryer at the end of the drying season. The dryer
should not be used for grain storage. Grain left in there for an
extended period of time can become wet, swell and spoil.
Chunks of spoiled grain can plug the metering system and
swelled grain places undue stress on the interior and exterior
sheeting of the dryer.
Clean out the plenum roof grain cushion and remove any grain
that may be hanging up on the plenum roof.
Make sure the grain exchangers are clean.
Clean out the hopper that divides the heat section from the
cooling section.
Clean the cooling chamber floor.
Remove all grain and trash from the metering drum floor. This
grain can be raked out by hand by opening the slide gates
located in the hopper bottom of the dryer.
Make sure gas supply is shut off to the dryer.
Open the gas train drain valve located on the bottom of the gas
train.
It is a good practice to cover the burner with a tarpaulin or
plastic to insure a clean burner.

supplied with the drive or at www.ab.com/manuals/dr.
General Precautions
!
ATTENTION: The drive contains high voltage capacitors which take
time to discharge after removal of mains supply. Before working on
drive, ensure isolation of mains supply from line inputs [R, S, T (L1,
L2, L3)]. Wait three minutes for capacitors to discharge to safe voltage
levels. Failure to do so may result in personal injury or death.
Darkened display LEDs is not an indication that capacitors have
discharged to safe voltage levels.
!
!

!
ATTENTION: Equipment damage and/or personal injury may result
if parameter A092 [Auto Rstrt Tries] or A094 [Start At PowerUp] is
used in an inappropriate application. Do not use this function without
considering applicable local, national and international codes,
standards, regulations or industry guidelines.
ATTENTION: Only qualified personnel familiar with adjustable
frequency AC drives and associated machinery should plan or
implement the installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or
equipment damage.
ATTENTION: This drive contains ESD (Electrostatic Discharge)
sensitive parts and assemblies. Static control precautions are required
when installing, testing, servicing or repairing this assembly.
Component damage may result if ESD control procedures are not
followed. If you are not familiar with static control procedures,
reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.
ATTENTION: An incorrectly applied or installed drive can result in
component damage or a reduction in product life. Wiring or application
errors, such as, undersizing the motor, incorrect or inadequate AC
supply, or excessive ambient temperatures may result in malfunction of
the system.

Prepare For Drive Start-Up
!
ATTENTION: Power must be applied to the drive to perform the
following start-up procedures. Some of the voltages present are at
incoming line potential. To avoid electric shock hazard or damage to
equipment, only qualified service personnel should perform the
following procedure. Thoroughly read and understand the procedure
before beginning. If an event does not occur while performing this
procedure, Do Not Proceed . Remove All Power including user
supplied control voltages. User supplied voltages may exist even when
main AC power is not applied to the drive. Correct the malfunction
before continuing.
Before Applying Power to the Drive
❏ 1. Confirm that all inputs are connected to the correct terminals and are
secure.
❏ 2. Verify that AC line power at the disconnect device is within the rated
value of the drive.
❏ 3. Verify that any digital control power is 24 volts.
❏ 4. Verify that the Sink (SNK)/Source (SRC) Setup DIP Switch is set to
match your control wiring scheme. See page 5 for location.
Important: The default control scheme is Source (SRC). The Stop
terminal is jumpered (I/O Terminals 01 and 11) to allow
starting from the keypad. If the control scheme is changed
to Sink (SNK), the jumper must be removed from I/O
Terminals 01 and 11 and installed between I/O Terminals
01 and 04.
❏ 5. Verify that the Stop input is present or the drive will not start.
Important: If I/O Terminal 01 is used as a stop input, the jumper
between I/O Terminals 01 and 11 must be removed.
Applying Power to the Drive
❏ 6. Apply AC power and control voltages to the drive.
❏ 7. Familiarize yourself with the integral keypad features (see next page)
before setting any Program Group parameters.
Start, Stop, Direction and Speed Control
Factory default parameter values allow the drive to be controlled from
the integral keypad. No programming is required to start, stop, change
direction and control speed directly from the integral keypad.
Important: To disable reverse operation, see A095 [Reverse Disable].
If a fault appears on power up, refer to page 11 for an explanation of the
fault code. For complete troubleshooting information, refer to the
PowerFlex 4 User Manual on the CD supplied with the drive.

Series NP-LE AIRFLO® Burners
Installation Instructions
General
Important: Do not discard packing material until
all loose items are accounted for.
Avoid bending or damaging the steel mixing plates
of your Series NP-LE AIRFLO® Burner during
uncrating and installation.
These burners are used
for the heating of fresh air
in motion. Mount the
burners so they fire parallel
to and in the same direction as the movement of
the air (see sketch 1 at
right).
Velocity and flow of air
at operating temperature
must be uniform. Minimum
silhouette profile plates of
6" should be installed in
duct to completely surround burner assembly.
Sketch 2 shows the burner suspended from a strap
iron frame using Maxon USB support brackets. Note
that rigid mounting is avoided by the bracket hole
which slips loosely over a bolt or steel rod attached to
the support. Gas piping would need independent
support.
Sketch 3 shows the burner assembly resting upon
angle iron brackets and not attached to them in any
way. Be sure the angle iron supports allow the burner
flanges to expand and contract. Gas manifolding
would be independently supported and prevent
forward movement of the burner.
Supports
Series NP-LE AIRFLO® Burner assemblies must be
adequately supported and positioned.
Avoid rigid mounting. Burner assembly expands
and contracts with temperature variations.
Maintain smooth, even air flow over the burner by
designing supports to provide minimum interference,
deflection and turbulence.

support methods:

Installation Instructions (cont'd.)
Gas Train
See piping layout below to identify various typical
system components.
Pipe size of gas line must be large enough to
assure ample fuel pressure at maximum system
capacity. Burner capacity is totally dependent on fuel
differential being maintained. (See capacity/specification data for the actual fuel pressure required at the
burner to achieve its rated capacity.)
Clean fuel lines are essential to prevent blockage
of pipe train components or burner gas ports. All dirt,
scale and pipe dope should be blown out of any gas
line before actually connecting to the burner system.
Main shut-off cock should be upstream of both
system regulator and pilot line take-off. Use it to shut
off fuel to both pilot and main burner during extended
shutdown periods. Maxon Control Valves are not
intended for tight shutoff. Main system shut-off should
always be accomplished with a manual fuel cock.
Main gas regulator is essential to maintain a
uniform system supply pressure. A separate regulator
should be provided in the branch leading to each
burner system if more than one is served by a common main. Size regulator for full system capacity at
required pressure, including pipe train losses.
The gas train piping illustrated should be installed
as close to the burner as possible.
Pilot take-off should be upsteam of main gas
regulator, but downstream of main gas cock. It
normally includes pilot shut-off cock, pilot gas regula-
tor and pilot solenoid valves. For pilot adjustment, a
fixed orifice, or adjustable orifice is recommended at or
near the pilot gas inlet.
Fuel shut-off valves, when properly wired to a
safety control system, shuts the fuel supply off when a
hazardous operating condition is sensed by your
control circuit. Manual reset valves require operator
attendence each time the system is started up (or
restarted after a trip-out). Motorized shut-off valves
permit automatic start/restart when used with appropriate control system.
Fuel control valve controls burner heat release by
throttling gas flow to it. It should include provision for
an adjustable minimum and throttling over a turndown
range that matches burner capabilities. The illustration shows a Series "CV" Flow Control Valve; but
adjustable gradient SYNCHRO® and/or "Q" Flow
Control Valves may be used.
Gas pressure test connections are provided in
most Series NP-LE Burner end plate sets, but it is
also helpful to provide an additional test connection in
the piping between main gas regulator and fuel
control valve. All connections must be plugged unless
an actual pressure measuring device (gauge or
manometer) is being used.
Maxon assumes no responsibility for the use
or misuse of the piping layouts shown.
Specific piping and wiring diagrams should
always be submitted to the appropriate
agencies for approval on each application.

Start-Up Instructions
Read complete instructions before proceeding, and
familiarize yourself with all the system's equipment
components. Verify that your equipment has been
installed in accordance with the original manufacturer's current instructions.
CAUTION: Initial adjustment and light-off should
be undertaken only by trained and experienced
personnel familiar with combustion systems,
with control/safety circuitry and with knowledge
of the overall installation. Instructions provided
by the company and/or individuals responsible
for the manufacture and/or overall installation of
complete system incorporating Maxon burners
take precedence over these provided by Maxon.
If Maxon instructions conflict with any codes or
regulations, contact Maxon Corporation before
attempting start-up.
6.
For initial system start-up:
1.
Close all burner fuel valves and/or cocks. Make
preliminary adjustments to fuel regulators.
Check all electric circuitry. Verify that all safety
devices and interlocks are operable and functioning within their respective settings/ranges.
Be sure all manifolds are tight and that test ports
are plugged if not being used.
Check that all duct and chamber dampers are
properly positioned and locked into operating
positions.
Start main volume air fan. Check for proper
motor rotation and impeller direction. Verify all
safety interlocks are working. Allow air handling
equipment to run adequate purge of manifold
and combustion chamber plenums. Verify air
volume and velocity across burner element to be
within burner operating specifications.
2.
3.
4.
CAUTION: Do not by-pass control panel timers
typically controlling sequential operations.
5.
6/03
Disconnect the automatic control motor linkage
from your Maxon Control Valve by loosening the
control motor's connecting rod from the valve's
toggle linkage. Initial start-up adjustment should
only be accomplished during a "manual" control
mode. Manually set and secure control valve in
its "minimum" position.
7.
8.
To light and adjust gas pilot: Pilot gas regulator
should initially be set at 2-5” wc. With pilot gas
solenoid valves closed, open main fuel gas and
pilot gas cock. Energize spark ignitor and open
pilot gas solenoid. Turn adjustable orifice screw
out (counter-clockwise) several turns from its
fully seated position or adjust regulator pressure
when fixed orifice is used. Observe pilot ignition
through a sight port and/or by viewing micro-amp
signal metered from flame safeguard relay circuit.
Refine pilot setting for a hard blue flame (and/or
strongest micro-amp signal) by adjusting gas
flow through pilot orifice and/or pilot regulator.
Prepare to ignite main burner by adjusting main
gas regulator to approximately midpoint of its
adjustment range. Linkage arrangement for the
use of Series "CV" Gas Control Valve is illustrated above for a typical control motor. Arrange
accordingly.
With control valve at "minimum," ignite main
burner by opening main fuel shut-off valves.
Adjust main gas regulator to give the desired
outlet pressure. Refine pilot adjustment if it has
been affected. Adjust burner "minimum" by
turning in on the minimum stop screw of the gas
control valve until stable flame appears in the
narrow zipper channel at the base of burner
mixing plates.

Start-Up Instructions (cont'd.)
A good minimum fire should provide uniform
flame across the entire burner face, contained
within the zipper flame channel at the base of
burner mixing plates. Any thin spots or gaps
indicate uneven air velocity over the burner
which must be corrected or a higher minimum
fire established by continuing to turn in on the
minimum stop screw. (See drawing on page
5550-S-2.)
NOTE: If your Maxon NP-LE AIRFLO® Burner
was furnished with an adjustable gradient type
Series "Q" or SYNCHRO® Control Valve
instead of a Series "CV" Valve, refer to step
8A through 8I for specific instructions and
differences in adjustment procedures.
For Series “CV” Valves, skip to step 9.

A. From step #5, the automatic control motor
linkage has already been disconnected from
your adjustable gradient type control valve
and the valve is at its "minimum" position.
B. Open fuel supply and begin adjustment of
appropriate adjustable gradient valve by
turning in minimum (or lowest numbered)
screw until desired flame is achieved. (Main
fuel regulator may need adjusted at this
point.)
C. Once your flame is established and refined
at this position, and without advancing the
screw carrier quadrant higher, screw all
remaining screws down to at least the same
level as your first adjusted screw.
NOTE: A preliminary setting can be established with all the remaining adjusting
screws. Generally, each succeeding screw
needs to be screwed in approximately one
full turn deeper than its preceeding screw. A
smooth "stair-step" gradient pre-set at this
point from low to high will simplify the
m

remaining adjustment steps.
D. Without advancing the SYNCHRO® Valve
quadrant, screw down on #2 screw (one or
two turns). Then slowly advance the
SYNCHRO® Valve quadrant to the #2
position. Refine flame appearance at this
new position #2.
E. Turn all higher-numbered screws in at least
as far as the one just adjusted, then turn
next one in as necessary to achieve desired
flame while rotating valve mechanism to that
position on indicator strip.
F. Repeat for each remaining screw.
NOTE: To avoid possible damage to cam
strips, always turn all higher-numbered
screws in as far as the last one adjusted.
G. Refine adjustment as needed, always
turning valve so that position indicator
matches screw being adjusted.
For more fuel, turn screw in (clockwise). for
less fuel, turn screw out (counter-clockwise).
If screws must be turned in flush with carrier
casting, increase fuel pressure and readjust
by starting at minimum over again.
H. Cycle system off and on, and through all
firing rates until satisfied with performance.
I. Reconnect control motor linkage and check
that operator does not "bind" and that all
interlocks are performing properly.
Adjust burner "high fire" by slowly rotating fuel
control valve crank arm towards its maximum.
Observe flame characteristics carefully. Flame
should remain a bright blue color with a length
beyond the mixing plates as indicated in capacity/specification data. If flame becomes long and
yellow, gas pressure is too high and/or air
velocity is too low.
NOTE: Dust and/or chemicals entrained into
passing air stream may effect physical color of
flame. In this case, adjust burner for stable flame
shape and geometry.
To measure gas pressure, connect water
column (manometer) to the test connection in
burner's end plate. To determine air velocity, use
a velometer at the profile opening. Correct
velocities by increasing or decreasing profile
opening size.
If flame is too short, gas pressure may be too
low and should be increased or velocities are
too high and may need to be decreased. Note
that air velocities should be measured only
when the fan is handling air at the desired
control temperature.

Start-Up Instructions (cont'd.)
The desired maximum capacity may be
achieved with less than full control valve opening. Mark with a pencil or scribe the point on
valve crank arm where the desired maximum is
obtained, then return crank arm to low position
and shut system off.
10. If using Maxon Series “CV” Valve, reconnect
control motor linkage (with control motor in low
or minimum position) by loosening toggle clamp
screw 1 and moving toggle clamp 2 along the
connecting linkage to a point where toggle
clamp bolt 3 can be placed at the outermost
position of control motor crank slot. Then tighten
toggle clamp screw 1, thus fixing clamp to
linkage.
Allowing toggle clamp bolt 3 to slide in the crank
arm slot, cycle control motor towards its maximum position and move fuel control valve crank
4 to the previously-determined maximum firing
rate position. Tighten toggle clamp bolt 3, thus
fixing clamp to motor crank.
Cycle control motor back to minimum, watching
carefully that it does not bind before reaching
minimum.
If it is stopped or if minimum is not reached,
loosen toggle clamp screw 1 and move toggle
clamp along the connecting linkage so both
motor and valve can assume their minimum
positions. Then retighten toggle clamp screw 1.
Refine adjustment by cycling several times
between low and high control motor position
while readjusting toggle clamp bolt 3 as necessary until control motor travels through its full
cycle while moving control valve crank arm from
its minimum only up to the desired maximum
previously determined.
1/01
11. Relight burner and cycle control system from
low to high fire several times to observe performance. Refine adjustments of pilot and main
burner minimum if necessary.
Warning: Test every UV Flame Sensor
System for dangerous spark excitation from
ignitors and other burners, as well as other
possible sources of direct or reflected UV
radiation.
12. Check carefully that all interlocks and limits are
in full operating condition. Before system is
placed into full service, instruct operator personnel on proper start-up, operation and shut-down
of system. Establish written instructions for
reference.

Series NP-LE AIRFLO® Burners
Page 5550-S-11
Maintenance Instructions
Periodic maintenance will insure continued troublefree operation of your Series NP-LE AIRFLO® Burner
system.
At least a yearly inspection is recommended for
make-up air heating installations and more frequently
for process applications in year-round operation. Your
own experience is the best guide in determining
frequency of inspection. As a minimum, the following
procedure should be followed:
1. Shut the system down totally. Disconnect or lock
out power supply so there can be no accidental
start-up during inspection.
2. Inspect the burners carefully, including upstream
and downstream sides of mixing plates as well as
burner body face. Any accumulation of scale or
foreign material on either side of the mixing plates
should be removed with a wire brush. Check
visually that no holes in the mixing plates are
blocked. See next page (5550-S-12) for inspection and maintenance instructions for gas ports.
WARNING: Do not enlarge burner ports or
performance may be drastically affected.
If any mixing plates are loose or missing fasteners,
tighten/replace as necessary. Always use zinc plated
or stainless metric fasteners.
3. Put system back into operation and, if possible,
view from downstream side while cycling burner
through full firing range. This will give a visual
check for blocked burner ports.
4. Observe flame pattern and, if necessary, take
steps to correct velocity and/ or air distribution
problems.
Repair / Replacement Procedures
If adverse operating conditions or accidental
damage make it necessary to replace either individual
mixing plates or complete burner sections, follow this
procedure:
1. Identify necessary replacement parts from
component identification drawings on preceding
pages, then order required quantities of each.
Consider carefully the economics of installing a
complete replacement burner instead of replacing
individual parts. Once exposed to actual flame
temperatures, burner castings harden and the
removal and replacing of fasteners can be time
consuming and difficult. Accessibility may also be
severely limited requiring removal of complete
assembly in any case.
2. When necessary parts have been received,
remove damaged mixing plates or burner sections, taking care not to damage remaining
portion of burner. If new burner bodies are being
installed, place body gasket on the mating
flanges of loose cast iron bodies. (This is necessary to provide a gas-tight seal after assembly.)
Insert new section into place, making sure that
both flanges are square and flush, then bolt
sections together.
1/01
3. Install new mixing plates, back up bars and plate
support brackets to the new body castings.
4. If end plate sets must be installed, put in position
between mixing plates and insert fasteners
loosely. Do not tighten at this time.
5. Tighten burner body bolts making sure that
mating cast iron flanges remain square and flush.
6. Align mixing plates and check that body gaskets
are in position and properly aligned. Tighten all
mixing plate mounting screws and bolts.
7. Double check that all fasteners are secure.
8. Return burner to operation, observing flame
carefully at all firing rates.

Inspection and Maintenance of Gas Ports
– Conduct initial inspection within the first month
after commissioning. Visually check the gas ports
of new burner assemblies for any piping scale or
debris. Use Pin Vise with drill bit to remove.
– Annual inspections are normally adequate once
the initial piping debris is removed. The operating
conditions of the burner will determine how
frequently maintenance is actually required.
– Use of an electric drill motor is not suggested
unless both Pin Vise and Drill (as shown below)
can be chucked up in a vari-speed drill unit. Use
caution, because it is easy to snap the bits off in a
port when using a drill motor. Removal of broken
bits from the gas ports is difficult.
– Contact your Maxon representative to answer
questions or address any problems.

capacity and low pressure drop benefits of a butterfly
valve construction, plus an adjustable gradient feature
for accurate fuel flow control.
They are used independently for throttling of fuel
gases and with PREMIX® Blower Mixers and
AIRFLO® Mixers for stand-by fuel systems, where
they allow change-over to alternate fuels without readjustment.
Series “Q” Valves are UL (Underwriters
Laboratories) listed for use with air, natural gas and
liquefied petroleum gases.
3" Series “Q” Valve
Series “CV” Control Valves incorporate a fullflow, fixed gradient butterfly valve design for high
capacities at low pressure drops, using minimum
operating torque.
This economical assembly includes a minimum
stop screw and can be supplied with connecting base
and linkage assembly to mount your electric control
operator.
Versions available with UL (Underwriters
Laboratories) listing for air, natural gas and liquefied
petroleum gas service.
Series “BV” Balancing Valves are used to
balance gas or air flows in multiple-burner systems
fed by a common manifold. They feature a full-flow
butterfly design with provision for locking in any
position.

Flow Control Valves
Page 7000-S-1
Installation Instructions
– Support weight of piping independently. Do not
place any Maxon Flow Control Valve in a piping
bind. Provide pipe hangers and/or special support
for related manifolds.
– Maxon connecting base and linkage assemblies
are designed to locate and/or position the
control operator for its interaction with the Flow
Control Valve assembly. They are not intended to
support the weight of the control motor. Special
provisions will be required to support the weight of
the control operators.
– Use of pipe heavier than schedule #40 can
cause interference with butterfly-type Flow Control
Valves and restrict the valve from full opening.
– Flow Control Valves provide the means to
adjust fluid and/or gas flows. They should be
installed with at least four pipe diameter lengths of
straight pipe before and after the valve. This
lessens the chance of internal flow turbulence being
set-up in the piping manifolds and control valve.
– Check fluid flow direction through “-P” and “-O”
poppet-type valves. It must flow only in direction
matching the arrow cast into valve body. If necessary, valve body may be rotated per instructions
given on page 7016.
– Install flow control valves carefully and maintain
adequate dimensional clearance to allow full
stroke and travel of the valve’s control linkage.
Internal drive mechanisms within a control motor
may be damaged if linkage is restricted as to cause
binding in high or low flow position.
CAUTION: All Flow Control Valves are designed
for throttling service only and are not intended
for tight shut-off.
– Main system shut-off should always use a
manual “leak-tight” upstream fuel cock.
Mounting Instructions for motor operator on Series “CV” Flow Control Valves
For those Series “CV” Valve assemblies furnished with
connecting base and linkage, the accompanying diagrams
illustrate mounting procedures relative to each specific type
operator.
First, mount your control motor to connecting base in
accordance with diagrams at right.
Secondly, determine if your electric operator travels
through 90° or 180° rotations. Then arrange connecting
linkage and motor crank arm as shown below for your
specific operator.

Adjusting Instructions
Notice: Only generalized instructions can be provided
here. Detailed adjusting instructions are provided with
each individual Maxon burner and/or mixer system.
General Instructions
Important: Do not discard packing materials
until all loose items are accounted for.
To prevent damage in transit, some connecting
base and linkage components may be packed
separately and shipped loose with your new Maxon
Flow Control Valve.
The Flow Control Valve is normally only a part of
your complete combustion system. Additional pipe
train accessories and control components may be
required for a complete system installation.
Read complete instructions before proceeding,
and familiarize yourself with all the system’s
equipment components. Verify that your equipment
has been installed in accordance with the original
manufacturer’s current instructions.
CAUTION: Initial adjustment and light-off of
burner systems should be undertaken only by
trained and experienced personnel familiar with
combustion systems, with control/safety
circuitry, and with knowledge of the overall
installation. Instructions provided by the
company and/or individuals responsible for the
manufacture and/or overall installation of
complete system incorporating Maxon burners
take precedence over these provided by Maxon.
If Maxon instructions conflict with any codes or
regulations, contact Maxon Corporation before
attempting start-up.
For initial adjustment and/or burner start-up:
1. Close all burner fuel valves and cocks. Make
preliminary adjustments to fuel gas regulators.
2. Check all electric circuitry. Verify that all
control devices and interlocks are operable and
functioning within their respective settings/
ranges. Be sure all air and fuel manifolds are
tight and that test ports are plugged if not being
used.
m
CORPORATION
MUNCIE, INDIANA, USA
3. Check that any air handling dampers are
properly positioned and locked into operating
positions.
4. Disconnect the automatic control motor’s
linkage from your control valve’s operating crank
arm by loosening the control motor’s connecting
rod from the burner’s toggle linkage.
Initial adjustment should only be
accomplished during a “manual” control
mode.
5. Start all system-related fans and blowers.
Check for proper motor rotation and impeller
direction. Verify that all control interlocks are
working. Allow air handling equipment to run for
adequate purge of your manifolds.
CAUTION: Do not by-pass control panel timers
typically controlling sequential operations.
6. With MICRO-RATIO® Valve combinations of
air and fuel valves, the minimum differential
pressure setting is initially established with
the air valve only.
A. By disconnecting the linkage between the air
butterfly valve and interconnected fuel
valve(s), the minimum and maximum limits of
travel on the air valve may be determined.
For example, a combustion system may
need the air valve to be 15° open for the
“minimum” setting and the “maximum”
requirements are satisfied with the air valve
open to 60°. By marking these points on the
air valve’s indicating strip, you are ready to
reconnect the SYNCHRO Fuel Valve’s
linkage to the air valve.
B. The next step involves adjusting the
connecting linkage between the air valve
and the fuel valve(s) so that each fuel valve
travels its full quadrant range (i.e. from
minimum to maximum), while the air valve
swings from its pre-determined minimum and
maximum positions.
C. With Series “CV” Valves and Series “Q”
adjustable-gradient Flow Control Valves,
the minimum flow position is set by their
minimum stop screw. This adjustable stop is
located on the side of the screw carrier of
Series “Q” Valves and at the base of crank
arm of Series “CV” Valves. Screwing “in” on
the minimum stop screw produces a physical
stop on the quadrant’s travel that prohibits
valve from being completely closed off.

Installation Instructions
1. Read complete instructions before proceeding
and do not discard packing materials until any/all
loose items are located. Also, make sure that the
installation of the Maxon valves will be in compliance with all applicable governmental, insurance
and/or agency requirements or codes, such as
NFPA-70, National Electric Code, CSA C22.1,
Canadian Electric Code, etc.
2. General considerations:
A. Prior to shipment, each valve is operated
electrically and cycled at rated and 1-1/2
rated pressure while being leak tested. Every
Maxon valve is operationally tested and
meets the requirements of ANSI B16.104
Class VI Seat Leakage when it leaves our
plant.
B. Inspect your valve for any shipping damage.
Contact Maxon Corporation with the valve’s
serial number (printed on the valve's nameplate) for replacement and/or repair parts.
C. Read the nameplate on your valve. This
gives the maximum pressure, temperature
limitation, voltage requirements and service
conditions of your specific valve. DO NOT
exceed nameplate ratings.
D. Select mounting location carefully. Your
Maxon valve is designed to operate for many
years if installed in a location that is cool,
clean and dry.
3. Pipe the valve in the direction of the flow arrow
[3] on the valve body. The Maxon valve body can
shut off flow in one direction only.
A. Remove all thread and flange protectors
before installing valve in your service line.
B. Teflon tape acts as a lubricant and greatly
reduces the pipe wrench turning force required to seal the threads.
Take care not to overtighten threads as
this can damage the valve.
C. Good piping practice dictates that piping be
independently supported, so that valve bodies
are not placed in a bind. In addition, large
valves may require support.
D. Clean pipe lines of foreign materials before
installing valve into line.
For new installations, a gas filter or strainer shall be
installed in the fuel gas piping to protect the
downstream safety shut-off valves.
per NFPA 86-4-2.4.3 (1999)
NFPA 86C-4-2.4.3 (1999)
NFPA 86D-4-2.4-3 (1999)
If normal inlet pressure to the fuel pressure regulator immediately upstream from the valve exceeds
the valve’s pressure rating, a relief valve shall be
provided and it shall be vented to a safe location.
per NFPA 86-5-7.1.7 (1999)
NFPA 86C-5-7.1.7 (1999)
NFPA 86D-5-7.1.7 (1999)
E. Mount valve so that open/shut window
indicator [1] will be visible to your operating
personnel. The open/shut window indicator
should never face downward. With Maxon
electro-mechanical top assemblies, the motor
access side plate [2] should always be
vertical to the ground. Valves are usually
installed in horizontal piping; however, other

orientations are acceptable, subject to the
above limitations. The top assemblies of all
Maxon valves are field rotatable to allow
installations involving conflicts with these
mounting restrictions.
F. Main system shut-off should always use a
manual leak-tight upstream fuel cock.
G. Time lag between valve action and fluid flow
(or flame response) is reduced if valve is
located near the burner (or outlet).
4. Wire the valve in accordance with all applicable
codes and standards. Supply voltages must agree
with valve’s nameplate voltage within -15%/+10%
AC or DC for proper operation. For electrical
wiring schematics, refer to appropriate Maxon
catalog literature and/or the wiring schematic
diagram affixed inside your valve’s access cover
plate or in the terminal block cover housing.
A. The Maxon valve must be electrically
interlocked with your safety-limit devices in
accordance with all applicable codes, standards, and the authority having jurisdiction
over the safety requirements for your overall
system installation. Normally, Maxon valves
are electrically wired in series with all of your
safety-limit devices. Therefore, any one
device can cause the valve to react. Each
valve was production tested when manufactured. If it now appears inoperative, make
sure it is being powered properly from and
through your control circuit.
m
CORPORATION
MUNCIE, INDIANA, USA
B. Maintain integrity of Maxon top assembly
enclosure by using dust and water-tight
electrical connectors. Use cable-sealing grips
and strain-relief loops for any cord or cable.
Use internal sealing materials on all conduit
connections. Moisture can have a harmful
effect on valve internals if permitted to enter
through wiring connectors. Make sure that all
access cover plates are in place and securely
fastened. All cover screws should be tightened using an alternate cross corner tightening pattern to the values shown below.

While all covers are torqued at time of production testing, torque should be rechecked
periodically to ensure adequate sealing
protection.
5. Pre-operational exercising:
Prior to initial fluid flow start-up and with upstream
manual cock still closed, operate the valve
electrically for 10-15 cycles. This not only provides an electrical check, but also wipes valve
body disc and seat free of accumulated foreign
matter.

90° increments around the valve body centerline axis
by the following procedure:
1. Shut off all electrical power and close off upstream manual cock.
2. Remove wiring access cover plate [2] and
disconnect power lead wires. (Tag carefully for later
re-assembly.)
3. Remove conduit and electrical leads.
4. Note physical position of any signal switch
actuator wands on auxiliary signal switches (see
switch arrangement sketch).
5. Unscrew the two body bolts [4] screwed up from
the bottom to 1/4 inch. DO NOT completely remove. These bolts secure the valve body [3] to the
valve’s top assembly housing [5].
6. Gently lift the top assembly [5] (not more than
1/4" in height); just enough to break the seal
between the valve body assembly and the rubber
gasket adhering to the bottom of the top housing.

Top Assembly Rotation (cont'd.)
7. Remove the two body bolts [4] screwed up
from the bottom (were partially unscrewed in
step 5).
8. Carefully rotate top assembly to the desired
position in a plane parallel to the top of the valve
body casting. Rotate the top housing about 30°
beyond this position, and then rotate it back.
Reposition the top housing back down onto the
valve body casting. This should align the open/
shut indicator with its window and provide proper
alignment of the internal mechanism.
9. Realign holes in valve body casting with the
corresponding tapped holes in the bottom of the
top assembly housing. Be sure the gasket is still
in place between the body and top housing.
10. Reinsert the body bolts up from the bottom
through the body and carefully engage threads of
the top assembly. Tighten securely.
11. Reconnect conduit and electrical leads, then
check that signal switch wands are properly
positioned and that open/shut indicator moves
freely. Failure to correct any such misalignment can result in extensive damage to the
internal mechanism of your valve.
12. Energize valve and cycle several times from
closed to full open position. Also electrically trip
the valve in a partially opened position to prove
valve operates properly.
13. Replace and secure side cover access plate
and place valve in service.

Page 6100-S-5
Operating Instructions
Refer to appropriate catalog bulletin and specification page for operating sequence applying to your
specific valve. Never operate valve until all essential allied equipment is operative and any necessary purges completed. Failure of electro-mechanically operated valve to operate normally indicates that
it is not powered. Check this first! Then check
internal holding solenoid and/or motor operator.
Main system shut-off should always be accomplished with an upstream leak-tight manual fuel
cock.
All Maxon valves react within a fraction of a
second when de-energized (can drop out if electrical
power is interrupted for less than 1/2 cycle [8 ms]).
All electro-mechanical manual reset valves may
be operated manually when solenoid is electrically
energized, but electrical tripping is recommended
for normal shut-downs.
Electro-mechanical manual reset valves require
two positive actions to open: a half rotation of
handle to latch internal mechanism, and a reversed
half rotation of handle to open valve. This refers to
normally closed valves. With normally open valves,
the procedure is the same, but the valve body position
(i.e., open or closed) is opposite to the normally
closed version.
Remotely located manual reset valves may be
equipped with wheel-and-chain assembly. Instructions
to operate the valve are on hand grip. Locate counterweight overhead at pipe level and hand grip can be
brought down to convenient operating personnel
height.
Normally closed motorized valves begin opening cycle immediately upon being powered; motor
runs only until full open position is reached. Normally
open valves begin to close immediately, and motor
runs until fully closed position is reached.
Operator should be aware of and observe characteristic opening/closing action of the valve. Should operation
ever become sluggish, remove valve from service and contact Maxon for recommendations.

Maintenance Instructions
Maxon valves are endurance tested far in excess of
the most stringent requirements of the various approval agencies. They are designed for long life even
if frequently cycled, and to be as maintenance-free
and trouble-free as possible.
Every Maxon valve is operationally tested and
meets the requirements of ANSI B16.104 Class VI
Seat Leakage when it leaves our plant.
Top assembly components require no field
lubrication and should never be oiled.
Auxiliary switches, motors and solenoids, may be
replaced in the field.
WARNING: Do not attempt field repair of valve
body, top assembly or motor drive unit. Any
alterations void all warranties.
Valve leak test, performed with valve in line as
prescribed by jurisdictional authorities, is strongly
encouraged and should be done on a regularly
scheduled basis. In rare instances where valve shows
leakage, perform Pre-Operational Exercising (see
below) and retest. If leakage does not stop, remove
valve from service.
Pre-operational exercising: Prior to initial fluid
flow start-up and with upstream manual cock still
closed, operate the valve electrically for 10-15 cycles.
This not only provides an electrical check, but also
wipes valve body disc and seat free of accumulated
foreign matter.
Insurance authorities agree . . .
. . . that the safety of any industrial fuel burning
installation is dependent upon well-trained
operators who are able to follow instructions and
to react properly in cases of emergency. Their
knowledge of, and training on, the specific
installation are both vital to safe operation.
Safety controls may get out of order without the
operator becoming aware of it unless shutdowns
result. Production-minded operators have been
known to bypass faulty controls without reporting
the trouble.
Continued safe operation of any installation is
then assured only if the plant management
carefully develops an exact schedule for regular
periodic inspection of all safety controls, insisting
that it then be rigidly adhered to.
A main gas shut-off cock should be located
upstream from all other fuel train piping components and used to shut off all flow of fuel for
servicing and other shutdowns.
All safety devices should be tested at least
monthly* and more often if deemed advisable.
Periodic testing for tightness of manual or motorized shut-off valve closure is equally essential.
*per NFPA 86-Appendix B-4 (1995)
Maxon valves are designed to be used with
clean fluids. If foreign material is present in the
fuel line, it will be necessary to inspect the
valve to make certain it is operating properly. If
abnormal opening or closing is observed, the
valve should be removed from service. Contact
your Maxon representative for instructions.
Operator should be aware of and observe characteristic opening/closing action of the valve. Should operation
ever become sluggish, remove valve from service and contact Maxon for recommendations.

Field Installation Instructions
NOTE: Instructions below are written for normally
closed valves. For normally open versions (STOM, STO-A, Fig. 1 & 2), reverse switch nomenclature. (VOS becomes VCS and vice versa.)
General: Shut off fuel supply upstream of valve, then
de-energize valve electrically.
– Remove top or side cover to provide access, being
careful not to damage gasket.
– Compare with illustrations at right to identify YOUR
valve type.
To replace existing switches:
– Note wand position and mounting hole location
carefully, then remove 2 screws and lift existing switch.
– Install replacement switch in same mounting holes on
bracket and verify correct wand position.
– Replace existing wiring one connection at a time,
following original route and placement.
To add switches to existing valve:
– Check illustrations at right. If your valve uses a switch
mounting bracket as in Fig. 1 & 2, mount switches to
bracket using the mounting holes appropriate for valve
type and size.
– Position bracket so VCS wand just touches top of
actuator, then move downward slightly, depressing
wand until switch clicks, then tighten mounting screws
to hold this position.
– Pin bracket by drilling 1/8" dia. holes 1/4" deep into
bracket mounting pad through drive pin holes, then tap
drive pin in until flush.
– Route wires to wiring compartment as shown, then
complete wiring connections and clean out metal
drilling chips from previous procedure.
– Cycle valve, checking switch actuation points carefully.
(VCS actuates at top of stem stroke, VOS at bottom.)
Simultaneously the valve body must be tested for
switch continuity and seat leakage. Bend VOS switch
wands slightly if necessary to insure valve is opening
fully.
– Replace gasket and cover, then return valve to
service.

(for simultaneous opening of main and blocking valves)
Installation Instructions
Review and comply with all general valve installation instructions provided separately. (See sketch
below.)
1. Mount both valves in fuel line with center to center
spacing as originally specified, and blocking valve
(without handle) downstream of main valve (with
handle).
2. Check valve alignment to be certain that operating wheels lie in the same plane.
3. Remove tape from the wheel of the main valve
and unwind the attached chain. Do not remove
the screw holding chain to wheel; it has been
factory positioned to assure correct alignment. Do
not remove tension spring attached to one end of
chain or the wooden block insert which preloads
the spring.
4. Take free end of chain and loop it around the
wheels of both main and blocking valve as shown
in sketch below. Depending on the specific valve
series and arrangement, tension spring may be
located either above or below the wheel centerline.
5. Draw free end of chain and tension spring together so that as much slack as possible is
eliminated, then insert the open eye of the spring
"S" hook through the link in the chain that will
most nearly maintain this position.
6. Crimp the "S" hook shut around the chain link,
then cut and discard excess chain.
7. Remove spring preload wood block insert from
the tension spring, and verify that the chain is
drawn tight.
8. Rotate the operating handle of the main valve
fully to latching position for your particular valve,
then hold handle firmly in this position while
performing the next few steps.
9. Rotate blocking valve wheel fully counter-clockwise until it strikes a stop (it will slide within the
loop of chain).
10. Still holding main valve wheel in place, move
blocking valve wheel approximately 1/4 to 1/2
inch back in the clockwise direction. Insert the
#10-24 X 1/2" screw (furnished) through the chain
link that lines up with the tapped hole on bottom
of blocking valve wheel, then fasten securely.
11. Verify that the valves are wired in parallel as
shown in wiring schematic on page 6121.
To add wheel & chain assembly to
existing tandem valves:
1. Verify that both valves are in the same top
assembly position (TO or AW). Rotate if necessary. (See top assembly rotation instructions on
pages 6100-S-3 and 6100-S-4.)
2. Bend handle of main valve outward about 25°.
3. Cut off handle of blocking valve at outer wheel
face.
4. Remove hardware holding main valve wheel in
place and mount new wheel and spacer to the
existing wheel with new hardware provided.
5. Cut chain loop to the desired length and secure to
both wheels.

Overhead Wheel & Chain Assembly
Overhead wheel and chain assembly allows
operation of a manual reset valve in an otherwise
inaccessible overhead location. A wheel is mounted
onto the handle of the valve. The attached chain is
weighted on one end and has a paddle handgrip on
the other.
Once the valve is electrically energized, pulling
down on the paddle will open normally closed versions or close normally open versions.
Maxon valve's free-handle design permits valve to
trip to its rest position on any power interruption.
Wheel and chain assembly includes a length of
chain to position the paddle handgrip slightly below
pipe centerline. A standard length of 7 feet of chain is
included with CP and larger valve sizes and 5 feet is
included with all other valves. Extra chain (in one foot
increments) may be specified to fit your specific
location.

Maintenance Instructions
CAUTION: Valve leak testing should be undertaken only by trained and experienced personnel.
Instructions provided by the company and/or
individuals responsible for the manufacture and/or
overall installation of complete system incorporating Maxon valves take precedence over these
provided by Maxon. If Maxon instructions conflict
with any codes or regulations, contact Maxon
Corporation before attempting this procedure.
Valve leak test should be performed on a
quarterly basis to assure continued safe and
reliable operation. Each valve should be checked
with available line pressure. Absolute zero leakage
may not be obtained in the field. Any valve that
exceeds the allowable leakage, as set forth by your
local codes or insurance requirements (15 bubbles
per minute), should be removed from service and
your Maxon representative should be contacted.
Every Maxon valve is operationally tested and
meets the requirements of ANSI B16.104 Class
VI seat leakage when it leaves our plant.

THRUST PLATE
In applications, which are subject to high vibratory loads, a thrust
plate will provide greater resistance to axial movement. Follow
the manufacturer’s recommendations for assembly.
SHRINK DISC
If a shrink disc is used to secure a reducer hollow shaft to the
driven shaft, follow this assembly procedure. Start with the shrink
disc mounted onto the extension of the hollow shaft disc locking
bolts loosened.
1. Clean reducer bore and mating solid shaft to be free of any
lubricants or dirt.
2. Slide reducer onto the solid shaft until it is about half way
through.
3. Lubricate the remaining portion of the solid shaft with a #2
grease or similar lubricant. This part will be located under
the bronze bushing. Do not install grease under the
shrink disc gripping area. Finish installing the solid shaft
into the reducer hollow bore.
4. Finger tighten all shrink disc bolts. Now, moving a circular
pattern, tighten each shrink disc locking bolt 1/4 to 1/2 turn.
Do not use criss cross pattern. Continue tightening in the
same circular direction with 1/4 or 1/2 turn increments until
all bolts reach the specified bolt tightening torque. Bolt
tightening torque is shown on the shrink disc label for the
particular unit.
5. Run unit for 24 hours, then retighten shrink disc locking bolts
to the proper bolt torque as indicated above.
Outboard pinion and sprocket fits shouId be as recommended by
the pin sprockets with interference fits shouId be heated
according to the manufacturer’s recommendations, generaIIy
250qF to 300qF, (120qC to 150q C) before assembIing to the shaft.
LOCATION
CoupIing hubs shouId be mounted fIush with the shaft ends,
unIess specificaIIy ordered for overhung mounting. Pinions,
TORQUE REACTION ARM
On the shaft mount ‘Clincher’, torque is reacted through the
integral torque tab, which is part of the casting. Commonly,
NORD’s optional RUBBER BUFFER bushings are installed on
each side of the integral torque tab to dampen torque shocks and
allow for mis-alignment received from the machinery during
operation.
Torque arm connection fabrications should always be mounted
perpendicular to a line through the output shaft center and the
point at attachment of the torque arm to the unit housing. In this
position the minimum load on the attachment structure arm will be
experienced. The attachment structure must be rigid and may not
deflect under any load. Doing so will place extra loads on the
output bearings of the reducer.
PRIME MOVER MOUNTING
AIign the prime mover to the reducer-input shaft using shims
under the feet. Make sure that the feet are supported. DoweI the
prime mover to its foundation.
sprockets and sheaves shouId be mounted as cIose as possibIe
to the unit housing to minimize bearing Ioads and shaft
defIections.
SHAFT CONNECTIONS
When connecting shafts to either the input or output of the
reducer, consider the foIIowing instructions.
FITS
CIearance or interference fits for coupIing hubs shouId be in
accordance with ANSI/AGMA 9002-A86 or as follows.

COUPLING ALIGNMENT
Shaft coupIings shouId be instaIIed according to the coupIing
manufacturer’s recommendations for gap, anguIar and paraIIeI
aIignment. In many instaIIations, it is necessary to aIIow for
thermaI and mechanicaI shaft movement when determining shaft
aIignment. The coupIing manufacturer’s recommendations
shouId be foIIowed.
CHANGES IN PERFORMANCE SPECIFICATIONS
AXIAL DISPLACEMENT
The gap between shaft ends shouId be the same as the specified
coupIing gap unIess overhung mounting of the coupIing hub is
specified. The coupIing gap and shaft gap must be sufficient to
accommodate any anticipated thermaI or mechanicaI axiaI
movement.
LOCK OUT POWER before any maintenance is performed.
Make absolutely sure that no voltage is applied while work is
being done on the gearbox.
Owner has the responsibiIity to consult with NORD GEAR if such
items such as applied Ioads, operating speeds or other operating
conditions have changed.
WARNING:
ANGULAR ALIGNMENT
Insert a spacer or shim stock equaI to the required coupIing gap
between the coupIing hub faces and measure the cIearance using
feeIer gauges. Repeat this at the same depth at 90-degree
intervaIs to determine the amount of anguIar misaIignment.
START-UP
1.
2.
PARALLEL ALIGNMENT
Mount a diaI indicator to one coupIing hub, and rotate this hub,
sweeping the outside diameter of the other hub. The paraIIeI
misaIignment is equaI to one-haIf of the totaI indicator reading.
Another method is to rest a straight edge squareIy on the outside
diameter of the hubs at 90-degree intervaIs and measure any
gaps with feeIer gauges. The maximum gap measurement is the
paraIIeI misaIignment.
Ensure that switches, aIarms, heaters, coolers and other
safety and protection devices are instaIIed and operational
for their intended purpose.
Verify that the installed mounting position is the same as the
nametag mounting position. If not, adjust the oil level
accordingly and relocate the vent plug, fill plug and drain
plug according to the mounting position. See following.

The Autovent plug is brass in color and will be located at the
highest point on the gearbox. It operates like a check-valve to
allow the reducer to relieve internal pressure while preventing
lubricant contamination during cooling. A spring presses a ball or
plunger against a machined orifice until pressure exceeds 2 psi.
Above 2 psi the air is allowed to escape depressurizing the
gearcase. When internal pressure drops below 2 psi, the
autovent re-seals closing the unit to the outside environment.
After shutdown, the reducer cools along with the air inside the
reducer. The unit will temporarily maintain a slight vacuum until
normalization occurs. NORD Gear supplies an Autovent as a
standard feature.
CHECKING ALIGNMENT
After both anguIar and paraIIeI aIignments are within specified
Iimits, tighten aII foundation boIts secureIy and repeat the above
procedure to check aIignment. If any of the specified Iimits for
aIignment are exceeded, reaIign the coupIing.
SPROCKET OR SHEAVE ALIGNMENT
AIign the sheaves or sprockets square and paraIIeI by pIacing a
straight edge across their faces. AIignment of bushed sheaves
and sprockets shouId be checked after bushings have been
tightened. Check horizontaI shaft aIignment by pIacing a IeveI
verticaIIy against the face of the sheave or sprocket. Adjust beIt
or chain tension per the manufacturer’s specified procedure.
OUTBOARD PINION ALIGNMENT
AIign the pinion by adjusting the gear tooth cIearance according
to the manufacturer’s recommendations and checking for
acceptabIe outboard pinion tooth contact. The foundation boIts
may have to be Ioosened and the unit moved sIightIy to obtain
this contact. When the unit is moved to correct tooth contact, the
prime mover shouId be reaIigned.
RECHECK ALIGNMENT
After a period of operation, recheck aIignment and adjust as
required.

FILL LEVEL & DRAIN PLUGS
The drain plugs are metric socket head cap screws. They will be
located at the lowest part of the gearbox for ease of draining. The
fill level plug is a hex head cap screw. It will be located between
the Autovent and drain plug. Both types of plugs will have gaskets
included to prevent oil from leaking.
LUBRICANT
AII NORD reducers are shipped from the factory properIy fiIIed
with Iubricant and all plugs are installed according to the mounting
position given on the reducer nametag. Acceptable oil fill level is
within ½ inch of the bottom of the fill plug threads.
OPERATION AND MAINTENANCE CHECKLIST
1. Operate the equipment as it was intended to be operated
2. Do not overIoad.
3. Run at correct speed.
4. Maintain Iubricant in good condition and at proper IeveI.
5. Dispose of used Iubricant in accordance with appIicabIe
Iaws and reguIations.
6. AppIy proper maintenance to attached equipment at
prescribed intervaIs recommended by the manufacturer.
7. Perform periodic maintenance of the gear drive as
recommended by NORD.

MAINTENANCE
Mineral lubricant should be changed every 10,000 service hours or after two years. For synthetic oils, the lube should be changed every
20,000 service hours or after four years. In case of extreme operating (e.g. high humidity, aggressive environment or large temperature
variations), shorter intervals between changes are recommended.
OIL SPECIFICATIONS
NORD supplies aII reducers fiIIed with oiI from the factory. Consult the sticker adjacent to the fill plug to determine the type of lubricant
installed at the factory. Standard lubricant is ISO VG220 mineral-based oil. However, some units have special lubricants designed to operate
in certain environments or to extend the service life of the lubricant. If in doubt about which lubricant is needed, contact NORD Gear.

Mounting
1. Mounting on Exact Planes
The Horizontal Type oil-lubricated units must be
mounted on horizontal surfaces. Where they are
mounted on inclined surfaces, some modifications may
be necessaly. Specify mounting plane inclination at time
of ordering.
2. Accurate Alignment
Where the reducer is connected to the motor and the
driven machine through couplings, align the shafts
accuratelv. Where the reducer is connected through V
pulleys o i sprockets, insure that the belts or chains are
neither too tight nor too slack.
3. Overhung Load Positions
Overhung loads should be located as close to the
bearing as possible. (See the SM-CYCLP 6000 Series
Catalog page E-8.)
4. Foundations
Foundations must be rugged enough to withstand shock
and stress applied from the load side through the
reducer.
Comct
Incorrect
Reducer Wall

Square And Parallel
5. Secure Housing
Where the reduction units are operated under conditions
of vibration and/or frequent starts and stops, it is
recommended to secure them on their mounting
surfaces by inserting dowel plns into the knock-holes
provided on the foot of the casing. This will insure that
bending or shearing forces are reduced on the mounting
bolts. Pins must be securely inserted, particularly when
the units are to be operated under conditions of severe
recurrent peak loads.
6. Mounting Accessibility
The reduction units must be mounted in locations with
easy accessibility for lubrication maintenance purposes.
7. Ventilation
When the SM-CYCLOBSpeed Reducer is mounted in a
SeDarate enclosure, be sure that adeauate ventilation is
provided.

Replenish grease to the reduction mechanism 113 to 112 of
the quantity listed in Table A-9 or A-10 for the first reduction
stage at the interval recommended in Table A-8.
When the unit is disassembled for overhauling, refill with
the grease quantities indicated in Table A-9 or A-10. Or
altefnatively,80% of the space around the reduction
mechanism and slow s ~ e e d
shall bearinqs of sinale
reduction units, and 50% around the rediction mechanism
of both the first and second stage of double reduction units.
Slightly larger quantities may be supplied to lower
ratio units, and somewhat smaller auantities for hiah
reduction ratio units.

Oil Lubricated Models
Oil Fill Procedure
011
lubricated models are not filled with oil prior to shipping.
Before start-up, remove the oil fill plug (See Pg. A-3,
Fig. A-2, Part #28) and fill the reducer with recommended
oil. Refer to Tables A-11-A-14 for standard oil, allowable
viscosity, quantity, and change interval. The oil level must
be to the upper red line on the oil level gauge while the unit
is not o~eratina.and above the lower red line durina
operation. If tco much oil is supplied, the unit's o Gating
temperature will rise due to the churning heat of tEe oil, or
oil will leak across the high speed shaft oil seal.
Before fillin a vertical base pe unit with oil, remove the
vent plug (8g. A-3, Fig. A-2, {att #14). After filling, apply
teflon sealina
- taDe
. to threads of the vent .olua before
installing.
When draining oil, remove drain plug (Fig. A-5, Part #46) or
lower side plug of the oil level gauge.
-
Oil Level Gauge
The auge must be replaced when it becomes difficult to
checi the oil level due to discoloration of the vinyl hose.
Use the standard vinyl oil auge for a reducer operatin in
ambient temperature -4"Qto 100°F (-20% to 40°C). &here
the reducer is used at ambient temperatures greater than
100°F (40°C) or less than -4°F (-2O0C), a glass gauge set
or a di~stickis recommended.
The oi; level gauge can be attached on either side of the
casing
on horizontalunits, Attach on the side that is most
convenient for checking the oil level. (The oil level gauge IS
usually attached on the right side when viewed from the
slow speed shaft end.)

Disassembly
SM-CYCLOmReducers aredesigned to provide
maximum ease when disassembing and reassembling;
they require no special maintenance skills.
1. Remove the complete SM-CYCLO' Reducer with
adaptor (motorized type) from the driven machine.
2. Remove the plug at the bottom of the oil gauge to
drain all oil from the unit.
3. Remove the cooling fan cover and fan from those
Speed Reducers (not motorized) equipped with a
cooling fan, and stand the unit on a solid base with its
high speed shaft side down. Remove the through bolts
for the high speed end shield, ring gear housing, and
lift the slow speed side, thus separating the unit into
two parts so that the inner mechanism can be removed
(Figs. A-12 A17).
Note: If the reducer is motorized (C-adaptor and
coupling) remove the motor and coupling before
following the procedure outlined above. As a final step,
remove the adaptor and cooling fan.
4. If the unit will not separate easily, gently drive a
wedge at the line X shown in Fig. A-1 on page A-3 (if
this produces a burr, be sure to remove it before
reassembly).
5. To lift the slow speed side, attach an eyebolt to the
tapped hole on the end of the slow speed shaft and
use a hoist or chain block (Fig. A-12).
6. Take out the slow speed shaft rollers, item 1-06,
page A-3 (Fig. A-13). Check the slow speed shaft pins
(1-01) to see whether any rollers have adhered to
them.
7. Using both hands, lift out the top cycioid disc (2-04)
on the slow speed side (Fig. A-14).
-
8. Remove the spacer ring (2-05).
9. The eccentric (3-04) can be removed from the
input shaft (3-01) after taking out the retaining ring
(3-10) and the inner bearing raceway (Figs. A-15,
A-16).
Note: In certain sizes, the eccentric bearings are
roller bearings without a retainer. Remove bearings of
the top disc before proceeding with the next step.
10. Take out the second disc located on the motor
side. (Also remove second disc bearings and
eccentric with inner bearing raceway if required.)
11. Remove the ring gear housing (2-01).
12. Follow these steps to remove the slow speed
shaft (1-01) with its bearings from the casing (26): (a)
Remove the horizontal oil seal housing (25). (b) With
a wooden or hard rubber mallet, rap the inner end of
the slow speed shaft to expose the retaining ring*
from the outer raceway of the bearing. (c) Remove
the retaining rina. Id)
. . RaD the outer end of the slow
speed shafwith a wooden or hard rubber mallet, and
remove it from the casing.
13. The high speed shaft (3-01) with bearings is
removed from the high speed shaft end shield (8) by
tapping the shaft end after first taking off the retaining
ring (3-1 1).
14. The cvcloid disc is made from heat-treated
bearing sieel and the spacer ring is cast iron. Take
care not to strike them together while handling.
The above instructions cover complete disassembly.
In ordinary cases, however, only the removal of the
cycloid discs and the eccentric, and removal of the
slow speed shaft from the slow speed end cap is
necessary.
*Note: Retaining ring is part of bearing A
(Part No. 1-02).
-
Assembly
SM-CYCLP Reducers are reassembled by reversing
the disassembly procedure. Care must be taken to
exclude dust or foreign matter from the moving parts,
and to see tnat aaskets are oro~erlv
. .olaced to make the
assembly oil-tight.
. .
Following are some helpful points to remember when
assembling SM-CYCLO" Reducers.
1. Set the ring gear housing and insert the ring gear
pins and rollers; then test-rotate the pins and rollers by
hand. (Apply grease liberally to the ring gear pins and
rollers before they are inserted in grease lubricated
SM-CYCLP Reducers.)
2. Cycloid discs are a matched pair. Each carries the
same number stamped on one side of the disc.
3. Set the cycloid disc with the stamped number face up
as shown in Fig. A-17.
4. lnsert the spacer (3-07) and then insert the
eccentric w~thbearlngs by rapplng wtth a wooden or
hard rubber mallet (Fig. A-16).
5. lnsert the other spacer and the inner bearing
raceway. Secure them with the retaining ring
(Fig. A-15).
6. Set the spacer ring in place.
7. lnsert top disc in such a way that the mark is
180" opposed to the mark on the bottom disc
(Fig. A-1 3).
8. lnsert slow speed shaft rollers (Fig. A-13).
9. Put the slow speed shaft pins into the rollers (Fig.
A-12). The above instructions are for eccentric
bearings with retainer. Following are the instructions
suggested for roller bearings without retainer.
a. First insert the eccentric with inner raceways of
bearings by rapping with a wooden or hard rubber
mallet.

c. Insert the spacer ring and set second disc in such a
way that mark is 180' opposed to mark on the bottom
disc.
Eccentric Bearing Replacement Pre~autlonS
The eccentric bearings are specially designed for'installation on SM-CYCLO. Reducers. They are special
roller bearings without outer raceways (refer to the list
of bearings on pages A-12 A-13).
It is necessary to insert replacement bearings with
numbered surfaces of the inner raceways facing
outward. Note that incorrect insertion of the bearings
(i.e., insertion of bearings with numbered surfaces
inside) causes trouble.
Disassembly and Assembly of Skee 60608095
SM-CYCLtY Reducers
Small sizes 6060-6095 have a single disc system, so
they differ in construction from larger sizes in the
following ways:
1. A balance weight is provided in lieu of the two-disc
system. Refer to figure A-18.
2. The balance weight must be positioned exactly 180"
as opposed to that of the eccentric.
3. There are no end plates on either side of the
eccentnc. In all other respects, 6060-6095 have
exactly the same construction as the larger sizes.
Follow the instructions given under "Disassembly and
Assembly".
Disassembly Of Output Side (6060812H)
1. With casing supported, tap output shaft until it is
disengaged from casing.
2. Remove bearing "A" by using pulling tool.
3. Replace all bearings, gaskets and seals when
reassembling. (Pages A-1 1 A-13).

Assembly Of Output Slde (6080812H)
1. Assemble the "B"bearing (Part No. 1-03) on the slow
speed shaft (Part No. 1-01). Heating of '6" bearing is
recommended for easter assembly.
Note. Do not exceed temperature of 200°F.
2. Assemble Me casing (Part No. 26) over the slow speed
shaft (Part No. 1-01), being sure to maintain "X" (Fig. A-18).
3. Carefully tap bearing 'A" (Part No. 1-02) onto the slow
speed shaft (Part No. 1-01) until the bearing is flush with the
shoulder of the casing.
4. Place the collar (Part No. 1-04H) onto the slow
speed shaft (Part No. 1-01). Heating Me collar is
recommendedfor easier assembly.
5. Insert the oil seal (Part No. 18), lip in, into the casing
(Palt No. 26).
Note: Measure for dimension "X" preferablyin 3 places to
insure proper spacing.

DAILY INSPECTION
fluctuation is small. If temperature rises rapidly from a
stable condition, add the recommended oil or grease
(Tables A-7 and A-1 1). A rapid temperature rise may
be caused from a lack of lubrication.
1. Visually check the oil level gauge on the vertical
unit, forced-lubricated type. Check lubrication flow by
viewing piping set and oil signal (Part No. 41). Faulty
operation is caused by a lack of lubrication oil,
damage to the plunger pump (Part No. 42) or the
positive displacement pump (Part No. 43) or the
clogging of pipes, etc. In case of faulty operation, stop
and inspect the unit immediately.
If after lubricating unit, the problem persists, stop
operation and consult factory.
3. When an abnormal sound is heard from inside the
unit, stop operation and inspect the unit.
2. A temperature rise of approximately 105°F (40.6%)
above ambient on the surface of the ring gear housing
(Part No. 2-01) is allowable if the temperature
4. If the lubrication oil leaks, replace the damaged or
worn part with a new one. (Refer to Part No. 1-04H,

Adapter Bracket
Damper Linkages
The 220738A Adapter Bracket, positioned between the motor
and the equipment, raises motor shaft height by 0.75 in.
(19 mm) to match that of previous Modutrol® Motor models.
The motor does not include a crank arm. Order the crank arm
separately (see Accessories in the Specifications section). For
detailed instructions on the assembly of specific linkages,
refer to the Installation Instructions packed with the linkage.
The following applications require this bracket:
• Q607 External Auxiliary Switch.
• Damper linkage applications requiring added clearance to
allow:
— Crank arm rotation through the downward position.
— Sufficient damper linkage to reach the motor shaft.
• All valve linkages except the Q5001.
NOTE: When the bracket is not used in a replacement
application, the damper linkage requires adjustment
for the new shaft position.
To mount the motor with the bracket:
1. Mount the bracket to the equipment with existing or
standard bolts.
2. Using the provided bolts, mount the motor to the bracket
threaded holes. See Fig. 3.
For valve linkage applications (other than the Q5001):
1. Mount the bracket to the linkage.
2. Position the motor on the bracket to align the motor
shaft with the linkage.
3. Attach the motor to the bracket with the four bolts
provided. See Fig. 4.
CAUTION
Equipment Damage Hazard.
Stalling a motor can damage the drive shaft.
Ensure installation of motors and linkages allows the
motor to drive through full stroke without obstruction.
Valve Linkages
The Q100 Linkage requires a 220738A Adapter Bracket for all
valve applications. Applications with the Q5001 Valve Linkage
do not require the 220738A Adapter Bracket (see Fig. 4).
For detailed instructions on specific linkage assemblies, refer
to the instruction sheet packed with the linkage. In general,
check the following points when installing a motor and linkage:
• Adjust valve and louver-type damper linkages so the
damper or valve moves through only the maximum required
distance while the motor moves through its full stroke.
• With modulating control, maximum damper opening should
be no more than 60 degrees. Little additional airflow is
provided beyond this point.
• Do not exceed load and torque ratings in any application.
Junction Box
When used with liquid-tight conduit connectors, the junction
box provides NEMA 3 weather protection for the motor. The
junction box, standard with replacement motors, encloses the
terminals and provides knockouts for wiring conduits. Housing
an internal transformer or internal auxiliary switches requires
using a junction box.

Auxiliary Switch Adjustment
IMPORTANT
When adjusting the auxiliary switch cams use the
following procedure:
1.Insert 1/8 in. screwdriver blade into a slot on cam
and move the screwdriver top as far as possible in
the required direction. See Fig. 10.
2.Repeat step 1 in successive cam slots until the
cam is in the required position.
Use the following procedure to obtain the desired auxiliary
switch settings:
1. Remove the top cover from the motor to gain access
to the motor terminals and auxiliary cams.
2. Disconnect the controller from the motor.
3. Connect a current source to the positive and negative
terminals.
4. Drive the motor to the position where the auxiliary
equipment is to be switched by increasing or decreasing
the current.
5. For a switch differential of 1°, check continuity of auxiliary
switch contacts R-B and rotate the cam as follows:
a. If the contacts are open, rotate the cam clockwise
until the R-B contacts close.
b. If the contacts are closed, rotate the cam
counterclockwise until the R-B contacts open.
MOVE SCREWDRIVER AT
TOP ONLY TO ADJUST CAM.
6.
7.
8.
9.
10.
For a switch differential of 10° rotate the cam
approximately 180° so the slow-rise portion of the
cam actuates the switch.
Check continuity of the auxiliary switch contacts R-B.
Rotate the cam as follows:
a. If the contacts are open, rotate the cam
counterclockwise until the R-B contacts close.
b. If the contacts are closed, rotate the cam clockwise
until the R-B contacts open.
c. Make final adjustment in the proper direction to
obtain contact make or break at the desired position.
Check for the proper differential and switching of the
auxiliary equipment by driving the motor though the full
stroke in both directions.
Disconnect power, remove current source, reconnect
the controller, and replace the top cover on the motor.
NOTE: Changing the differential from 1° to 10° reverses the
switching action. For example, with a 10° differential,
switch contacts R-B make and R-W break on a
counterclockwise (closed) rotation. With a 1°
differential, switch contacts R-W make and R-B
break on a counterclockwise (closed) rotation.

OPERATION AND CHECKOUT
Operation
The motor feedback potentiometer and control current input
circuit form a bridge circuit. As long as the final control
element remains at the position proportional to the input
current from the controller, the circuit is balanced, and the
motor does not run. When the value of the controlled medium
changes, the current from the controller changes, and
unbalance is amplified to energize the Triac switching to run
the motor in the proper direction to correct the change in the
temperature or the pressure. The motor turns the feedback
potentiometer to rebalance the circuit and stop the motor.
Checkout
After installation and linkage adjustment, operate the motor
through the controller. Make sure that:
• The motor properly operates the damper or valve.
• The motor responds properly as the input is varied.
• The auxiliary switch, if used, operates at the desired point
of motor rotation.
Inspect the motor, linkage, and valve or damper to see that all
mechanical connections are correct and secure.
In damper installations, the pushrod should not extend more
than a few inches past the ball joints. Check to see that
there is adequate clearance for the linkage to move through
its stroke without binding or striking other objects.
See controller or system instructions for additional checkout
procedures.
Motor Operation Checkout
Check motor operation as follows:
1. To close the motor, open terminals +, -, and F.
2. To open the motor, connect terminal F to the
negative (-) motor terminal.

Regulator Installation and
Maintenance Instructions
Model 121
Regulators
Introduction
Start-Up
Streamlined body passages provide large capacity. An external
control line is required from lower case to control piping. The 121
has a fast speed of response, yet is stable in operation. Soft seats
assure positive tight shutoff. Orifices are replaceable. Springs
are color coded.
B. Note the set-point (set-point is the outlet pressure the regulator is adjusted to deliver). Regulator is factory adjusted to the
set-point specified on the order.
The Model 121 Regulator represents a combination of capacity,
performance and value...
And it is also available as a zero governor or atmospheric regulator, a differential regulator, a relief valve or backpressure regulator, vacuum regulator or vacuum breaker.
Installation
1. Examine the regulator for shipping damage.
2. Check nameplate data. Be sure regulator conforms with
what was ordered.
3. Inside of regulator and piping must be clean and free of
dirt. Remove all dirt and debris before installing regulator.
Failure to remove dirt/debris could result in regulator damage or trouble.
4. Remove all shipping screens and covers from the regulator. Do not let dirt get inside the regulator.
5. Install the regulator.
Make sure the inlet and outlet are correctly connected.
High pressure connects to the inlet. The flow arrow must
point downstream.
6. Screwed connections must conform with good piping practice free of excess thread engagement per ANSI B2.1
Apply pipe joint compound to male threads only.
7. The Model 121 Regulator is usually right side-up as shown
on the Typical Installation drawing (See Page 2). It may,
however, be installed upside down. Although, when inverted
it may be necessary to readjust the set-point.
Caution: Do not install sideways. The diaphragm should
be horizontal.
8. On indoor installations requiring venting outdoors, run the
vent piping as short and direct as possible with minimum
bends and elbows. Use the same size or larger pipe as
the vent connections on the regulator. With natural gas, or
any other hazardous gas, vent to a safe place outdoors in
case gas should accidentally be discharged. Screen and
protect the opening outdoors to guard against water, ice,
dirt, debris or insects.
Install the control line. Connect it into the outlet piping at
least 5 pipe diameters downstream from the regulator.
CAUTIONS:
a. On backpressure regulators and relief valves the
external control line connects into the inlet piping,
5 pipe diameters upstream from the regulator.
b. Do not install any automatic shutoff device that
closes completely between the regulator and the
control line connection into the piping.
To avoid excessive turbulence, the connection should be
clean and smooth on the inside and be located in straight
pipe clear of valves and fittings. Keep the inside of the
control line clean and protect it from corrosion. Pitch it
away from the regulator and avoid moisture pockets. It
must be strong (1/4" for 121-8 and 121-12, 1/2" for 12116, or larger steel tubing or pipe is preferred). It must be
well protected against breakage (remember...regulators
open wide if the control line breaks).
9. Make sure the regulator is correctly connected and
adequately supported and pipe joints are tight.
A. The inlet and outlet shutoff valves should both be closed. If a
by-pass is used, the by-pass valve should also be closed.
CAUTION: This caution applies where the piping downstream
of the outlet shutoff valve is pressured. That pressure must not exceed the regulator set-point by
more than the pressure noted (see “Maximum
Emergency Pressures”, Page 18).
C. Slowly and carefully open the inlet shutoff valve just enough
to allow inlet pressure to build up slowly in the regulator until
it is fully pressured.
CAUTION: During start-up, a pressure gauge must be used
on the regulator outlet pressure and carefully
watched. While inlet pressure builds up, outlet
pressure must not exceed set-point by more than
1 psi. If outlet pressure begins to exceed set-point
by more than 1 psi, close the inlet shutoff valve.
This indicates the regulator is not closing properly.
Check and make necessary corrections before proceeding with start-up.
If regulator outlet pressure exceeds set-point by
more than the pressure noted, refer to “Maximum
Emergency Pressures”, Page 18 for instructions.
D. Check installation for leaks.
E. Slowly open the outlet shutoff valve to allow a small flow (approximately 1000 SCFH). Make sure the flow of gas does
not create a hazard.
NOTE: If piping downstream of outlet shutoff valve is pressured, see “CAUTION” under B.
F. With gas flowing, check for correct inlet and outlet pressures.
It may be necessary to further open the inlet shutoff valve to
maintain full inlet pressure.
G. Make sure the regulator closes tight (tight lock-up). To do this,
reduce flow to zero by slowly closing the outlet shutoff valve.
Outlet pressure should not exceed set-point by more than
6" w.c.
H. Fully open inlet and outlet shutoff valves. Do this slowly and
carefully. Watch pressure gauges.
I. Complete start-up by making sure there are no leaks.
NOTE
• Do not exceed the regulator’s pressure ratings. The
regulator outlet has a lower pressure rating than the
inlet. Do not expose the regulator outlet or control line
to inlet pressure.
Regulator with external control may be used as an
upstream monitor or upstream regulator in a monitor
set. The control line must connect into the outlet piping downstream of the downstream regulator.
• If the regulator is to be moved to another location,
make sure its construction is compatible with the pressure and flow conditions.
Temperature Limits
The Model 121 Regulator can be used for flowing temperatures
from –20°F to 150°F.
Buried Service
The Model 121 Regulator is not recommended for buried service.
Set Point Adjustment
A. The 121 is factory adjusted as specified on the order. To change
the set-point, readjust as follows:
1. Remove the top cap 1.
2. Adjust set-point with adjustment button 3, 3a or 6. Turn clockwise to increase and counterclockwise to decrease the
outlet pressure.
NOTE: a. Only make this adjustment when gas is actually
flowing through the regulator. The flow should be
small (approximately 1000 SCFH). Do not adjust
when the regulator is closed and there is no flow.
b. Do not increase the set-point beyond the upper
limit of the outlet pressure range for the spring 9
(refer to spring tables, Page 3).
c. Always check the outlet pressure with a pressure
gauge while adjusting the set-point.
3. When adjustment is complete, replace top cap 1. Screw it
securely into place. Leaving it off could cause unstable regulator operation.
CAUTION
It is the user’s responsibility to assure that all
regulator vents and/or vent lines exhaust to a
non-hazardous location away from any potential sources of ignition. Where vent lines
are used, it is the user’s responsibility to assure that each regulator is individually vented
and that common vent lines are not used.
To Change Spring
A. The outlet pressure ranges of spring 9 are given in the tables
on Pages 3 and 4. To change the spring:
1. Remove top cap 1.
2. Unscrew and remove adjustment button 3, 3a or 6 by turning counterclockwise, and remove spring 9.
3. Insert new spring. Make sure it is positioned correctly at the
bottom before replacing adjustment button 3, 3a or 6.
4. Adjust for the desired outlet pressure per previous section
“Set Point Adjustment”.
5. When adjustment is complete, replace top cap 1. Screw it
securely into place. Leaving it off could result in unstable
regulator operation.
6. New spring range should be marked on regulator. If old spring
range appears on regulator, it should be removed.
2
CAUTION
The diaphragm case vent must be positioned
to protect against flooding, drain water, ice
formation, traffic, tampering, etc. The vent
must be protected against nest building
animals, bees, insects, etc. to minimize the
chances for foreign material from collecting
in the vent side of the regulator diaphragm.
Shutdown
A. To take the regulator out of service, close the inlet stop valve
first. Close it carefully. Then close the outlet stop valve.
Before working on regulator, read the next section “General
Servicing Instructions” and the applicable servicing instructions.
CAUTION
Turn gas on very slowly. If an outlet stop valve is
used, it should be opened first. Do not overload
diaphragm with a sudden surge of inlet pressure.
Monitor the outlet pressure during start-up to
prevent an outlet pressure overload.
General Servicing Instructions
A. Before any disassembly of the regulator make sure it is completely depressured. Pressure must be fully released from the
inlet, the outlet and the control line connection. Failure to adequately depressure could result in serious personal injury.
B. Carefully note the location and position of all disassembled
parts to be certain reassembly is correct. Inspect each part
carefully and replace any that are worn or damaged or otherwise unsatisfactory.
C. Upon completion of servicing, make certain that the regulator
installation is entirely free of leaks.
CAUTION
Regulators are pressure control devices with
numerous moving parts subject to wear that
are dependent upon particular operating
conditions. To assure continuous satisfactory
operation, a periodic inspection schedule
must be adhered to with the frequency of
inspection determined by the severity of
service and applicable laws and regulations.

Servicing – General Instructions
To Service Orifice (19)
2. Carefully note location and position of all disassembled parts to be
certain reassembly is correct. Inspect each one carefully and replace those that are worn or damaged or otherwise unsatisfactory.
2. Remove main diaphragm assembly 11 per steps 1 through 4 “To
Service Main Diaphragm (11d)”.
1. Make sure the regulator is entirely depressured before servicing.
3. A moderate application of lubricant to O-ring 13 will help assure free
stem movement and a tight seal. Similar application of lubricant to
the other O-rings or Tetraseals will help assure their
tightness.
Do not use petroleum base lubricants.
4. Bolted connections should be tightened evenly and firmly.
Carefully tighten diaphragms into place. Bolts must be tight enough
to prevent leakage, but not so tight that the diaphragm material is
crushed or damaged.
5. Upon completion of servicing, make certain that regulator installation is entirely free of leaks.
To Service Valve (15)
1. Remove valve 15 per section “To Service Valve (15)”.
3. Remove seal diaphragm assembly 12 per steps 3 and 4 under “To
Service Seal Diaphragm (12b)”.
4. Remove retaining ring 19a. Use Truarc 0600 pliers, Invensys Part
No. 1190648.
5. Remove orifice 19 through top opening.
–
To reassemble, replace parts in reverse sequence.
(On reassembly, be sure that 19a is fully seated in its groove. Also,
beveled edge of 19a faces downward toward bottom cap 37.)
To Service Seal Diaphragm (12b)
1. Remove valve 15 per section “To Service Valve (15)”.
2. Remove main diaphragm assembly 11 per steps 1 through 4 “To
Service Main Diaphragm (11d)”.
1. Remove bolts 38 and remove bottom cap 37 and Tetraseal 32.
3. Remove bolts 25 and lower diaphragm case 24.
3. Remove both halves of valve holder 16b.
5. To disassemble 12, unscrew piston 12a from stem 12d. Use a
spanner wrench in notch in skirt of piston (this can also be done by
inserting a standard 7/32" Allen wrench in the notch).
2. Remove retaining ring 16a. Use Truarc 0200 pliers, Invensys Part
No. 1190646.
4. Remove valve 15 (wave washer 14 will probably also come off...do
not lose it).
–
To reassemble, replace parts in reverse sequence.
To Service Main Diaphragm (11d)
1. Remove top cap 1, and release and remove adjustment 3. On high
pressure Model remove cap 1a, release adjustment 3a, and remove
cover 5 and button 7a. Mark or measure position of adjustment 3 or
3a. Use this to return adjustment to this setting during reassembly.
2. Remove spring 9.
3. Remove bolts 22 and upper case 21.
4. Rotate diaphragm assembly 11 counterclockwise (this unscrews 11h
from 12d) and remove.
5. To disassemble diaphragm assembly, remove nut 11a. Carefully
note location and position of all parts to be certain of correct reassembly. Abrasive side of emery cloth washers face against
diaphragm.

To reassemble, replace parts in reverse sequence.
Make the screwed connection between 11h and 12d loose by
approximately 1/2 turn. To do this, carefully rotate diaphragm
assembly 11 clockwise until this screwed connection bottoms (do
not jam it together). Then, back-off diaphragm assembly 11 counterclockwise approximately 1/2 turn...this is very important...the 11h to
12d screwed connection must not be tight.
4. Remove bolts 29 and centerpiece 27, and then remove seal
diaphragm assembly 12.
–
To reassemble, replace parts in reverse sequence.
Make certain that fabric side of seal diaphragm 12b faces upward
and “rubber” side faces downward toward body.
Do not pinch loop in seal diaphragm 12b between ring 33 and
centerpiece 27. Also, rounded edge of 33 faces upward toward
seal diaphragm 12b.
Periodic Inspection: Regulators are pressure control devices with
numerous moving parts subject to wear that is dependent upon
particular operation conditions. To assure continuous satisfactory
operation, a periodic inspection schedule must be adhered to with
the frequency of inspections, determined by the severity of service
and applicable laws and regulations.

General Safety Instructions for
Gas Regulators

8. Check the regulator "set-point" and "lock-up" pressure. (Setpoint is the outlet pressure the regulator is adjusted to deliver.
Lock-up is the pressure where tight shutoff is achieved).
IMPORTANT: During start-up, a pressure gauge must be
connected to the outlet piping between the regulator outlet and
the downstream shutoff valve to closely monitor the outlet
pressure. When checking the regulator for set-point and lock-up,
provision must be made to PERMIT FREE FLOW of gas beyond
the outlet valve.
A
The regulator set-point is factory adjusted as specified on the
order. Set-point should be checked with small gas flow (10% of
maximum regulator capacity or less). Open the valve downstream of the regulator before turning on gas. Slowly open the
inlet valve while monitoring the outlet pressure gauge. Small flow
should be set by adjusting the outlet valve.
WARNING: Always closely monitor the outlet pressure gauge
during start-up while opening or closing valves and making
adjustments. If the outlet pressure continues to increase above
the specified lock-up pressure, open the downstream valve to
discharge the excess pressure and close the inlet valve.
Only adjust set-point when gas is flowing through the regulator.
DO NOT adjust if regulator is locked-up (tight shutoff).
IMPORTANT: Small flow during set-point adjustment is particularly important where set-point is in the top third of the spring
range. Large flow could result in over-stressing the spring or loss
of lock-up from the spring compressing solid. If the set-point
adjustment must be made at large flow (60% to 100% of maximum regulator capacity) and set-point is in upper third of spring
range, use the next higher range spring.
MONITOR REGULATORS AND
EXTERNAL CONTROL LINES
When bypassing a regulator with an external control line, the
control line valve must be closed before the bypass valve is
opened. Failure to do so could result in the diaphragm being
exposed to the inlet pressure.
USE WITH OTHER GASES
1. Do not use Equimeter regulators on corrosive gases unless
authorized by Equimeter for a specific corrosive condition.
2. Where the gas is propane or butane (LPG) and the
regulator has an internal relief valve (IRV), special care is
required with the regulator vent. Because propane and butane
are heavier than air, they do not disperse readily in the atmosphere. Instead, they tend to collect in low places. Since large
volumes can discharge from the regulator vent at times of
emergency, care must be taken to pipe any such discharge to
atmosphere at a safe place to prevent any gathering or migration
of explosive mixtures in low areas.
GENERAL INSPECTION AND
SERVICE INSTRUCTIONS
1. lnspect the regulator periodically to make sure it is in satisfactory working condition. Establish the frequency of inspection
on the basis of severity of service and applicable laws and
regulations. As a minimum recommendation, pressure regulating
and limiting equipment should be inspected at intervals not
exceeding 15 months, but at least once each calendar year.
2. If the regulator is to be moved to another location, make
sure its construction is compatible with the new pressure and
flow conditions.
After set-point has been determined to be correct, check for lockup by slowly closing the outlet valve. Again closely monitor the
regulator outlet pressure gauge. Regulator must be fully capable A w A R N I N G : Before any disassembly of the regulator, make sure
of tight lock-up. If outlet pressure continues to rise above the
it is completely depressurized. Pressure must be fully released

5. Upon completion of servicing, make certain that the regulator installation is entirely free of leaks.
It is the user's responsibility to assure that all regulator
vents andor vent lines exhaust to a non-hazardous location
away from any potential sources of ignition. Where vent
lines are used, it is the user's responsibility to assure that
each regulator is individually vented and that common vent
lines are not used.

AC Construction: Valve is designed to perform properly when mounted in
any position. However, for optimum life and performance, the solenoid
should be mounted vertical and upright so as to reduce the possibility of
foreign matter accumulating in the solenoid base sub-assembly area.
DC Construction: Valve must be mounted with solenoid vertical and upright.
Mounting
For mounting bracket (optional feature) dimensions, refer to Figure 1.
Connect piping to valve according to markings on valve body. Apply pipe
compound sparingly to male pipe threads only. If applied to valve threads the
compound may enter the valve and cause operational difficulty. Avoid pipe
strain by properly supporting and aligning piping. When tightening the pipe,
do not use valve or solenoid as a lever. Locate wrenches applied to valve body
or piping as close as possible to connection point.
CAUTION: To avoid damage to the valve body, DO NOT OVERTIGHTEN
PIPE CONNECTIONS. If Teflon* tape, paste, spray, or similar lubricant is
used, use extra care when tightening due to reduced friction.

Preventive Maintenance
Causes of Improper Operation
Positioning
e
All solenoid valves should be cleaned periodically. The time between
cleanings will vary depending on the medium and service conditions. In
general, if the voltage to the coil is correct, sluggish valve operation, excessive
noise or leakage will indicate that cleaning is required. In the extreme case,
faulty valve operation will occur and the valve may fail to open or close. Clean
valve strainer or filter when cleaning the valve.
1. Lubricate solenoid base gasket and body gasket with DOW
CORNINGr 200 Fluid lubricant or an equivalent high-grade silicone
fluid.
2. Install body gasket and core/diaphragm sub-assembly in valve body.
Locate the bleed hole in the diaphragm assembly approximately 45_
from valve outlet. The core/diaphragm sub-assembly is comprised of
a rider ring, core spring, core guide, hanger spring, core assembly, and
diaphragm assembly.
CAUTION: Do not distort hanger spring between core assembly and
diaphragm assembly.

6. Position connector gasket on solenoid and install plug connector. Torque
center screw to 5 ± 1 in-lbs [0,6 ± 1,1 Nm].
NOTE: Alternating current (AC) and direct current (DC) solenoids are built
differently. To convert from one to the other, it may be necessary to change
the complete solenoid including the core and solenoid base sub-assembly,
not just the solenoid. Consult ASCO.
Installation of Solenoid
Solenoids may be assembled as a complete unit. Tightening is accomplished
by means of a hex flange at the base of the solenoid.
Installation of Panel Mounted Solenoid (See Figure 1)
1. Disassemble solenoid following instruction under Solenoid Replacement
then proceed.
2. Install solenoid base sub-assembly through customer panel.
3. Position spring washer on opposite side of panel over solenoid base
sub-assembly.
4. Replace solenoid, nameplate/retainer and red cap.
5. Make electrical hookup, see Wiring section.
Solenoid Temperature
Standard solenoids are designed for continuous duty service. When the
solenoid is energized for a long period, the solenoid becomes hot and can be
touched by hand only for an instant. This is a safe operating temperature.
MAINTENANCE
WARNING: To prevent the possibility of death,
serious injury or property damage, turn off electrical
power, depressurize solenoid operator and/or valve,
and vent fluid to a safe area before servicing.
Cleaning
All solenoid operators and valves should be cleaned periodically. The time
between cleaning will vary depending on medium and service conditions. In
general, if the voltage to the solenoid is correct, sluggish valve operation,
excessive noise or leakage will indicate that cleaning is required. Clean
strainer or filter when cleaning the valve.
Preventive Maintenance
Keep the medium flowing through the solenoid operator or valve as free
from dirt and foreign material as possible.
While in service, the solenoid operator or valve should be operated at least
once a month to insure proper opening and closing.
Depending on the medium and service conditions, periodic inspection of
internal valve parts for damage or excessive wear is recommended.
Thoroughly clean all parts. Replace any worn or damaged parts.
Causes of Improper Operation
Faulty Control Circuit: Check the electrical system by energizing the
solenoid. A metallic click signifies that the solenoid is operating. Absence
of the click indicates loss of power supply. Check for loose or blown fuses,
open-circuited or grounded solenoid, broken lead wires or splice
connections.
Burned-Out Solenoid: Check for open-circuited solenoid. Replace if
necessary. Check supply voltage; it must be the same as specified on
nameplate/retainer and marked on the solenoid. Check ambient
temperature and check that the core is not jammed.
Low Voltage: Check voltage across the solenoid leads. Voltage must be at
least 85% of rated voltage.
Solenoid Replacement
1. Disconnect conduit, coil leads, and grounding wire.
NOTE: Any optional parts attached to the old solenoid must be reinstalled
on the new solenoid. For 3-way construction, piping or tubing must be
removed from pipe adapter.
2. Disassemble solenoids with optional features as follows:
Spade or Screw Terminals
