DESCRIPTION
The dimensional drawing (see below) identifies the various components of the
Algas-SDI TORREXX vaporizer. Multiple resistance heating elements provide
thermal energy to the finned aluminum heat exchanger. A solid state controller
monitors the heat exchanger temperature and regulates the operating
temperature to a predetermined set point. The controls consist of 2 individual Ktype thermocouple sensors with independent high temperature limits. One
sensor monitors operating temperature and the other controls the liquid inlet
solenoid valve. The liquid inlet solenoid valve does not open until a
predetermined warm-up temperature is reached. The vaporizer reaches
operating temperature in approximately 60 seconds from a cold start. The
vaporized LPG rises into the vapor header and exits through the vapor outlet.
The Liqui-SAFETM Valve is specially developed to prevent liquid from going
downstream.
The TORREXX Vaporizer can be configured for many applications.

INSTALLATION
GENERAL
Install the ASDI TORREXX vaporizer on a level firm base at least 6” above grade
and secure it through the four ½” holes. Protect the equipment against damage
by moving vehicles by use of an appropriate barrier. Consult state, provincial,
insurance carriers, and local authorities for installation requirements. Clean all
foreign material from all pipelines prior to making final connections. All joints
require a pipe sealant approved for LPG, depending on type of service. Test for
leaks using an inert gas, such as compressed carbon dioxide or nitrogen, at 1½
times the working pressure or as required by applicable codes. Check all
connections using an appropriate leak detection solution or device. Even very
small leaks are unacceptable. Eliminate all leaks prior to operation.
Install in accordance with applicable codes and local regulations as required.

LIQUID LINE
Size the liquid line from the storage tank to the vaporizer to supply the
vaporizer at full capacity with a minimal pressure drop. A liquid linesizing chart is provided in Table 6. Install a liquid line strainer with
magnet for iron particle pickup at the vaporizer inlet.
CAUTION
A liquid pump must be installed if the pressure drop in the liquid
line between the vaporizer and the tank exceeds the hydrostatic
liquid head in the storage tank. ONE FOOT OF LIQUID PROPANE
EQUALS .21 PSI! Liquid line frosting is a sure indication of too
much pressure drop in the liquid line.
LIQUID PUMP
Is a Liquid Pump necessary? What are your vapor pressure requirements?
Pressure in the storage tank depends on temperature See Table 5. A good “rule
of thumb” for determining when a Liquid Pump is necessary is this: If the storage
pressure will not always exceed the required distribution pressure by 5 psig (0.35
kg/cm2), a pump is necessary. Install an ASDI STABILAIRE Liquid Pump in the
liquid line close to the storage tank. To prevent cavitation, place the liquid
strainer at least five feet upstream of the pump inlet. Typically a pump is not
required unless a mixing system is used or temperature at the installation will be
extremely low, causing the pressure to drop below the required process
pressure.
VAPOR LINE
Install an appropriate regulator immediately downstream of the vapor outlet port.
Pipe from the outlet port of the regulator to the distribution system. Further
reduction of downstream pressure requires a “Second Stage” regulator close to
the consuming equipment. Properly sized piping and regulators will insure
satisfactory service.
NOTE
For safety reasons both FIRST and SECOND stage regulators must
be 250 psig (17.58 cm/kg2) inlet pressure rated!
3-11
ASDI Operations and Maintenance – TX Models – P/N: 52368
SAFETY RELIEF VALVE
If the vaporizer is to be installed within an enclosure or building, VENT THE
SAFETY RELIEF VALVE OUTSIDE THE ENCLOSURE AND REDIRECT THE
DISCHARGE UPWARD. A pipe-away adapter must be used at the relief valve.
Always install a rain-cap or similar device to prevent water and other debris from
entering the relief discharge. If water enters, it may freeze and prevent the relief
valve from proper discharge, creating a potentially hazardous situation.
ELECTRICAL SERVICE
The rating plate on the vaporizer and the data sheet provided with the manual
provides your specific vaporizer’s electrical power requirements and the drawing
numbers of the appropriate wiring diagrams and schematics. This unit is
constructed to meet NFPA 70 Class I, Division 1, Group D requirements. All
wiring to the unit, including the ground connection, must meet the applicable
codes for the area in which it is being installed. Wire size and type must comply
with the applicable codes for the area in which it is being installed. The Tables 1
through 4 list the recommended wire size for the different models. Those tables
are to be used as guides only. Provide a fused disconnect outside of the
classified area. If it is not within sight of the vaporizer, the fused disconnect must
have a locking device. Run wire within rigid conduit, and install a seal-off at the
connection of the field conduit to the vaporizer.
WIRE SIZE
When selecting the type and size of wire used to install the TORREXX series
electric vaporizers, please take into account the following environmental
information:
Ŷ
Maximum enclosure surface temperature: 65º C (150ºF).
Ŷ
Maximum enclosure ambient temperature: 65º C (150ºF).
Ŷ
Maximum temperature allowed at contactor terminals: 90º C (195º F).
Ŷ
Current draw of vaporizer: Indicated on vaporizer rating plate and on the
data sheet.
Ŷ
Contactor terminal lug wire size range: #2 - 10.
As the length of the wire run affects the overall wire size requirements, always
refer to NFPA 70 (NEC) for proper wire selection. Several wire-sizing charts
have been provided for determining the size of wire required due to load and
length of wire.
When installing the wire it is important to have a good connection at the terminal
lugs. Loose terminals may cause an excessive temperature rise at the terminal
lugs, which can lead, to premature contactor failure, transformer failure, and/or
overheating and possible destruction of the transformer. For this reason it is
strongly recommended that the wire terminations be checked and re-tightened
periodically to prevent excessive overheating at the terminals due to loose
connections.

OPERATION
GENERAL
The TORREXX Electric Vaporizer utilizes a finned cast aluminum heater core.
The heater core contains multiple cast-in resistance heater elements. Multiple
wiring configurations allow a variety of AC input voltages to suit local power
supply requirements.
Liquid LPG enters the vaporizer through the Liquid Inlet Solenoid Valve at the
base of the pressure vessel.
During operation, a K-type thermocouple temperature sensor and solid state
control system maintain the core temperature at 165°F (74°C) for LPG models
and 195°F (90°C) for Ammonia models. As the temperature increases on start
the Liquid Inlet Solenoid Valve opens at 131°F (55°C) liquid enters the vaporizer
and comes in contact with the heater core. Vaporization results as the liquid
extracts energy (heat) from the heater core. As the heater core cools, the
Temperature Sensor provides a signal to the control system to energize the
heater power contactor, applying power to the heater elements.
OPERATING INSTRUCTION
1) Complete the installation and leak test.
2) Check current and voltage to verify proper operation of the vaporizer.
3) This unit will not be damaged by operating the unit in a “dry” condition. It is
not necessary to have liquid in the unit for testing or evaluation.
4) Normal operating temperature is 165°F (74°C). Use caution when working
around vaporizer.
4-17
ASDI Operations and Maintenance – TX Models – P/N: 52368
STARTING THE VAPORIZER
CAUTION
Do not start the vaporizer when both inlet and outlet hand valves
are closed. Pressure can build in the vaporizer during startup and
blow the relief valve.
1) Close the outlet isolation valve.
2) Open all valves between the storage tank and the vaporizer to allow liquid
flow to the vaporizer when the solenoid valve opens.
3) Power unit. A small “click” should be heard immediately afterwards. The
vaporizer heater elements are now energized. It will take approximately 60
seconds for the vaporizer to reach operating temperature. After the unit
reaches operating temperature, the Inlet Solenoid Valve would open
automatically to allow LPG to enter. Wait approximately 2 minutes so that
excess LPG is pushed back to the storage tank.
4) Carefully press the Button on top of the Liqui-SAFETM valve all the way down
and SLOWLY release it. A latch mechanism inside the Liqui-SAFETM valve
will keep the Red Flag at the down position, indicating the valve is open.
5) The TORREXX vaporizer is now ready to supply vapor. Slowly open the
outlet isolation valve to pressurize the supply piping. Then, fully open the
outlet isolation valve to allow vapor to flow to the load. The heater will cycle
automatically to match the flow conditions.
STOPPING THE VAPORIZER
1) Close the outlet isolation valve.
2) Disconnect power.

MAINTENANCE
5
GENERAL
The TORREXX vaporizer is designed for long term trouble free operation.
Because of the nature of its use, and the severe duty it receives, it is important to
provide scheduled maintenance. A list of RECOMMENDED SPARE PARTS is
located in the back of this manual.
1) Clean the liquid inlet strainer after the first month of operation. Thereafter,
check every 6 months.
2) Annually, make a visual check of the safety relief valve located at the top of
the unit. Replace if any sign of leaking is observed. The relief valve is not
serviceable in the field. Be sure it is covered with an appropriate plastic cap
to prevent rain and debris from entering.
3) Every 6 months, make a performance check on the Liqui-SAFETM valve.
Test the shut-off mechanism (See below for instructions).
4) Every two years, replace all the o-rings in the Liqui-SAFETM valve. This
service is not serviceable in the field. See “Liqui-SAFETM valve – Service
Instructions” below.
5) Annually, change the inlet solenoid diaphragm. See the enclosed
Maintenance & Operation sheet for ASCO 2-way valves: Appendix A.
6) Make a visual inspection of the electrical wiring and connections in the
control housing every time you inspect the contactor insuring that the
connections are tight. See Contactor Replacement Schedule.
5-19
ASDI Operations and Maintenance – TX Models – P/N: 52368
CONTACTOR INSPECTION
WARNING
The Contactor that powers the heaters produces sparks which may
ignite any flammable vapors in the area when the control box cover
is removed. If the cover must be removed, shut off the power,
remove the cover and check very carefully for fumes, leaks, or any
indication of flammable vapors in the atmosphere or in the control
enclosure.
Do not re-apply power if fumes are present. They may ignite.
CAUTION
Keep a fire extinguisher available in the immediate vicinity before
re-applying power when the control cover is removed.
The TORREXX vaporizer utilizes an electro-mechanical contactor to switch
power to the heating elements. Since contactors wear out in normal operation, it
is prudent industry practice to inspect then on a preventive maintenance basis.
Manufacturers define a cycle life for contactors based upon operations at rated
current. The cycle rate of the contactor in vaporizers varies due to liquid
temperature/pressure, percent loading of the vaporizer, and installation specifics.
Vaporizer testing has demonstrated that cycle rates are greatest at around 50%
of the vaporizer loading and least when vaporizers are energized in a standby
mode.
We recommend the following inspection schedule for contactors:
i
5000 hours for vaporizers in service
i
30,000 hours for vaporizers in standby mode
i
For vaporizers operating in a combination of service and standby modes, we
are providing a simple formula to help determine when contactors should be
inspected.
Contactor life factor (LF) can be defined as follows:
LF=
X
5000
+
Y _
30000
When
X = hours of vaporizer operation mode
Y = hours of vaporizer in standby mode
If LF is 1 or greater, the contactor should be replaced.
This data is to be used only as a guide. It is not “fool-proof” as the environment
your vaporizer operates in and its load may affect the contactor life span.

Liqui-SAFETM valve – Performance check (Every 6 months)
I
Latch operation. – While the valve is in the open position and the Red Flag is
down, press Button and release QUICKLY. This will cause the valve to close
and the Red Flag to pop up. Carefully press the Button again all the way
down and release SLOWLY. The valve will stay open.
II
Leak detection. – Follow the instructions in “I” to manually open and close the
valve. Perform leak tests in both conditions. If a leak is detected at the Valve
Body (Step 1) when the valve is open, replace the Valve Body O-ring. If a
leak is detected in Step 5 when the valve is closed (see Figure 11), follow the
“Liqui-SAFETM valve – Service Instructions” and change all the o-rings. (This
service should not be performed in the field.)

Liqui–SAFETM Valve – Service Instructions
There are four (4) o-rings in the Liqui-SAFETM valve and these are the Button
Post o-ring, Valve Body o-ring, Valve Seat o-ring and Valve Stem Base o-ring. In
order to keep the valve working at its peak conditions, replacement of all the orings according to the maintenance schedule is strongly recommended. Due to
the complexity of the valve and the number of parts involved, this service should
NOT be done in the field. Follow the 7 Steps below to service the Liqui-SAFETM
valve. Clean all the metal parts with WD-40. Re-assemble all the parts. Simulate
the tripping action of the valve and verify the tripping force applied on the
Extension Stem be less than 0.5lbf (2.22 N).

IMPORTANT:
When reassembling the valve after servicing o-rings make sure that you apply super glue to the inside of
the magnet holder and press the magnet firmly in until it bottoms out. Allow sufficient time for glue to dry.
Always perform a functional check and leak test (see Figure 11) of the re-assembled valve to ensure that
it actuates per design and that valve seat o-ring seals properly against the valve body. Figure 12F shows
proper sealing of valve seat o-ring against valve body that should be observed prior to conducting a leak
test.

Full Load Voltage Check
NOTE
Current flow depends on the applied voltage. Voltage lower than
the specified voltage causes low current and may negatively affect
operation. Make all measurements with the heater ON (Contactor
closed).
WARNING
These tests include high voltage. Exercise great caution in making
the following tests. Carelessness could result in severe injury or
death. See additional warnings located at the beginning of this
Chapter.
FULL LOAD VOLTAGE CHECK
Check heater voltage by measuring voltage at the contactor terminals. See Data
sheet of your manual or rating plate on the vaporizer to determine the correct
voltage reading of your vaporizer. Measure voltage between all connected poles
of the contactor. The readings should be equal to +/- 3%.

NOTE
Refer to the Bussing diagram in Appendix A for wire to wire
resistance for your vaporizer.
CAUTION
Turn off electrical power at the disconnect before proceeding.
Carefully slide out the control panel for access to the heater wire connections on
the contactor. Measure the resistance across each pair of wires. An incorrect
resistance reading indicates a faulty heater element, a wiring problem, or an
open fusible link.

Solenoid Valve Leak Test
1) Shut off the outlet hand valve. The inlet hand valve should be open.
Start the vaporizer and allow it to heat up until the heaters shutoff. This
allows any accumulated liquid in the vaporizer to be forced back toward
the supply tank.
2) Disconnect the vaporizer by shutting off the power at the disconnect.
Shut off the inlet hand valve. Close the ball valve on the vaporizer
pressure gauge and remove the pressure gauge. Cautiously bleed off
any LPG pressure in the vaporizer and outlet supply piping. When the
pressure reaches no pressure in the vaporizer, reinstall the pressure
gauge and verify 0 pressure.
3) Turn on the inlet hand valve. The solenoid valve is closed and you
should not have any pressure build up in the vaporizer. If pressure
increases, the solenoid valve is leaking and needs to be repaired or
replaced.

Economy Operation
The Economy Option minimizes the electric power required to meet your vapor demand by shutting off the outlet
of the vaporizer when the natural vaporization rate of the storage tank is able to supply enough vapor to meet the
demand. A pressure sensing valve is specially developed to sense the upstream pressure. The valve opens when
the tank pressure falls below 30PSIG, and closes at 60PSIG. The pressure sensing valve is a mechanical device
and it operates independently to the electrical controls.
The Economy Option will NOT function if a pump is used.
The pressure set-point of the TORREXX Economy Valve is nonadjustable. Consult ASDI for any custom setpoint.
The Economy is normally a factory-installed option. However, a separate Economy valve can be purchased as an
add-on in the field.
For the Economy Valve field installation kit, use ASDI PN: 41051.
Make sure that the Economy Valve is correctly installed. Verify the flow direction on the Rating Plate.

TORREXX Economy Valve Maintenance
The TORREXX Economy Valve operates by sensing the pressure of the Vaporizer and Storage Tank. The
Economy Valve consists of a moving piston which opens and closes the valve’s outlet. The movement of the
piston is driven by the pressure force balance between two different sized o-rings and a spring.
Follow the instructions below and perform maintenance on the Economy Valve once every two years:
Figure 21A – STEP 1 – Unscrew the Inlet Housing from the Outlet Housing.
Figure 21B – STEP 2 – Replace the two O-rings (ASDI PN 39013 and 39014). Apply excess lithium o-ring
grease.
ASDI Operations and Maintenance – TX Models – P/N: 52368
7-38
Figure 21C – STEP 3 – Clean all o-ring contact surfaces and the bottom surface of the Outlet Housing.
Apply excess lithium o-ring grease.
Figure 21D – STEP 4 – Clean all piston surfaces. Apply excess lithium grease on o-rings.
Figure 21E – STEP 5 – Make sure that the Pin Hole is clear and the spring is undamaged. Carefully
reassemble all the parts. Apply lubrication grease on the straight threads if necessary.*
7-39
ASDI Operations and Maintenance – TX Models – P/N: 52368
* - The threads between the Inlet Housing and the Outlet Housing are straight threads and are designed to be
hand tightened. Gas will NOT leak through these threads because of the seals from the two o-rings. However, the
Inlet Housing MUST be screwed all the way down for the Valve to accurately function at the set pressure. Do
NOT apply sealing agent or Teflon tape on these threads.
Refer to the table below for any replacement parts in the TORREXX Economy Valve.

Mercury Relay
The life of the vaporizer can be further extended by using a Mercury Relay. Compared to a “dry” contactor, a
Mercury Relay reduces the wear and tear each time the heater cycles. A larger explosion-proof enclosure is also
used which improves access to the electrical controls.
This option is suitable for Class I Division 1 Group D and is only available in the NEC configuration.
The Mercury Relay Option can be integrated with all the other TORREXX options (i.e. Economy, Remote, etc.) In
addition, customized options such as external lamps/indicators, on/off switches are also available. Please consult
ASDI for details.

Filtaire – Contaminant Separator
The Filtaire is a filtering device designed to trap heavy hydrocarbons commonly present in LPG vapor. It also
traps other materials, which may be in the gas due to storage conditions and internal condition of the equipment.
Impurities are collected in the system and periodically removed through the system blow down drain. Residual
heavy end hydrocarbons with boiling points higher than pure LPG are trapped by the filter and fall to the bottom
for removal.
A complete Filtaire system consists of inlet and outlet connections, a blow-down drain (5), a pressure gauge (4), a
vent which is normally plugged (6), and a bypass valve system for cleaning (1, 2, and 3). The bypass valves
enable the system to continue operating when the Filtaire is removed for cleaning.
FIGURE 22 – Filtaire Operation
Leak Test
1. Close outlet valve.
2. Slowly open inlet valve and allow pressure to equalize in the vaporizer.
3. Apply a small amount of soap/water solution to ALL pipe connections.
4. Check for any leaks by observing new bubble formation in the soap/water solution.
Repair any leaks before continuing.

APPENDIX A
TECHNICAL
INFORMATION
ASCO Valve used by Algas-SDI
SOLENOID NOISE
Solenoid valves emit a sound when operated. When energized, they emit a
clicking sound. Also, accompanying the operation of most AC valves, is AC hum.
Whether or not AC hum is objectionable actually depends on the requirements
and opinion of the user. Normal AC hum is the result of the constantly reversing
magnetic field produced by alternating current. The constantly reversing
magnetic field can cause vibrations in the solenoid parts.
1. Solenoid noise due to damage solenoid parts such as bent solenoid base
assembly, stretched return springs, loose parts, etc.
Solution:
parts.
Inspect valve internals and exterior. Replaced damaged
2. Solenoid noise due to foreign matter between the core and plug-nut. When
foreign matter is trapped between the core and plug-nut, the core assembly
will rock back and forth at 60 hertz. Eventually, the core and plug-nut face
will be distorted, at which time the noise can continue even though the
foreign material may have been flushed or removed from the valve.
Solution:
Replace damaged parts entirely, clean and reassemble.
3. Solenoid noise due to damaged coil. On rare occasions, a severe voltage
spike or over voltage can potentially short a small portion of the coil winding.
This shorting can cause solenoid noise and coil overheating. However, it
would normally lead to rapid coil burnout. The solenoid parts, however,
could be damaged enough that the noise would continue even after the coil
was replaced due to the deformation produced during the peening process.
4. Missing solenoid parts can severely weaken the magnetic circuit. This can
produce a solenoid noise condition. As discussed above, it will probably also
result in coil burn-out.
Solution: Replace damaged parts, replace lost parts, clean and reassemble.
In general, when a noise condition has been encountered, the source of the
problem should be determined and eliminated. The valve should then be
thoroughly inspected to insure that it is yet repairable. Most times, simple
installation of a spare parts kit and a solenoid base sub assembly can restore a
valve to like new condition. The restored and reinstalled solenoid valve should
be tested to insure proper operation, and a voltage check should be made at the
solenoid valve while the valve is energized. In addition, a current reading can be
obtained and compared with catalog specifications to verify normal solenoid and
coil operation.
Note: The coil may have been damaged due to excessive current draw of at
damaged shading coil within the solenoid valve. A partial rebuilding of a valve
damaged by a noise condition can prove useless as the noise condition would
continue. The entire valve should be dismantled and inspected and cleaned. All
parts supplied in a spare parts kit should be installed. Further, and additional
solenoid parts damaged by a noise condition such as a solenoid base sub
assembly, should be replaced. Examine valve seating, pistons and the valve
body to verify that they have not been damaged. Damage to major portions of
the valve may make repairing the valve uneconomical.
Should a noise condition be encountered, immediate action may prevent any
damage to the solenoid valve itself.

CAUTION: To prevent fire or explosion, do not install solenoid
and/or valve where ignition temperature of hazardous atmosphere is
less than 165 C. On valves used for steam service or when a class
H" solenoid is used, do not install in hazardous atmosphere where
ignition temperature is less than 180C. See nameplate/retainer for
service.
NOTE: These solenoids have an internal non-resetable thermal fuse to
limit solenoid temperature in the event that extraordinary conditions occur
which could cause excessive temperatures. These conditions include high
input voltage, a jammed core, excessive ambient temperature or a shorted
solenoid, etc. This unique feature is a standard feature only in solenoids with
black explosionproof/dust-ignitionproof enclosures (Types 7 & 9).
CAUTION: To protect the solenoid valve or operator, install a
strainer or filter, suitable for the service involved in the inlet side as
close to the valve or operator as possible. Clean periodically
depending on service conditions. See ASCO Series 8600, 8601, and
8602 for strainers.

grounding, use a #10-32 machine screw. Torque grounding screw to 15 - 20
in-lbs [1,7 - 2,3 Nm]. On solenoids with screw terminals, the socket head
screw holding the terminal block to the solenoid is the grounding screw.
Torque the screw to 15 - 20 in-lbs [1,7 - 2,3 Nm] with a 5/32 hex key
wrench.
Junction Box
The junction box is used with spade or screw terminal solenoids only and is
provided with a grounding screw and a 1/2 conduit connection. Connect
#12-18 AWG standard copper wire only to the screw terminals. Within the
junction box use field wire that is rated 90C or greater for connections. For
steam service use 105C rated wire up to 50 psi or use 125C rated wire above
50 psi. After electrical hookup, replace cover gasket, cover, and screws.
Tighten screws evenly in a crisscross manner.
DIN Plug Connector Kit No.K236034
1. The open-frame solenoid is provided with DIN terminals to
accommodate the plug connector kit.
2. Remove center screw from plug connector. Using a small screwdriver, pry
terminal block from connector cover.
3. Use #12-18 AWG stranded copper wire rated at 90C or greater for
connections. Strip wire leads back approximately 1/4 for installation in
socket terminals. The use of wire-end sleeves is also recommended for
these socket terminals. Maximum length of wire-end sleeves to be
approximately 1/4.ĂTinning of the ends of the lead wires is not
recommended.
4. Thread wire through gland nut, gland gasket, washer and connector cover.
NOTE: Connector housing may be rotated in 90 increments from position
shown for alternate positioning of cable entry.
5. Check DIN connector terminal block for electrical markings. Then make
electrical hookup to terminal block according to markings on it. Snap
terminal block into connector cover and install center screw.
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
Remove terminal connections, grounding screw, grounding wire, and
terminal block (screw terminal type only).
NOTE: For screw terminals, the socket head screw holding the terminal
block serves as a grounding screw.

SWITCH UNITS
ADJUSTABLE DEADBAND SWITCH UNIT WITH GENERAL PURPOSE,
WATERTIGHT, OR EXPLOSIONPROOF SWITCH ENCLOSURE
DESCRIPTION
The SA---Series Adjustable Deadband Switch Units are used with transducer
units to make Tripoint Pressure Switches or Temperature Switches. The switch
units are made of aluminum alloy and designed for rugged industrial use.
Switches are provided with a general purpose, watertight, or explosionproof enclosure. All wiring terminals, adjustments, and visual scales are accessible from
the front of the switch.
The switch may be supplied as a complete unit or with the switch assembly unit
and transducer completely assembled. The components may be separate units to
be assembled upon installation. The actuation (set) point and the reactuation
(reset) point are each independently adjustable over the full range of the switch.
The switch assembly can be mated with a wide selection of pressure or
temperature transducers to cover a broad range of pressures, fluids, or
temperatures. The switch will control electrical circuits in response to changes in
pressure or temperature.
IMPORTANT: These instructions cover the installation and use of this
switch on pressure and temperature transducers. Select the paragraphs that
apply to your particular installation and application. The word signal is used
in place of pressure, or temperature changes.

Form No.V5720R2
Assembly of Switch and Transducer Units
IMPORTANT: The switch unit and transducer unit may be provided as a
complete assembly or as separate units. If separate units are provided refer
to Form No. V5771 for a complete listing of switch unit and transducer unit
combinations. Form No.V5771 is provided to ensure that the proper switch
unit is assembled to the proper transducer unit. Pay careful attention to
exploded views provided in Figure 3 for assembly of switch unit and
transducer unit. Proceed in the following manner:
CAUTION: The third digit in the catalog number on both the switch
unit and transducer unit must be identical. If not, do not assemble to each
other. If the same proceed.
1. Remove special instructions label and switch range scales from
transducer unit.
2. For watertight and explosionproof construction place gasket on base of
switch unit.
3. Place transducer unit on base of switch unit and assemble. Insert four
bolts and torque bolts in a crisscross manner to 80 ± 10 in---lbs
[9,0 ± 1,1 Nm].
4. Remove backing paper from range scale and install scale on the switch body
behind adjusting nut. The scale is slotted to fit over a raised boss on the
body. See Figure 1.
Positioning
INSTALLATION
Check the nameplate for the correct catalog number, pressure range,
temperature range, media, and proof pressure or temperature. Never apply
incompatible fluids or exceed the pressure or temperature rating of the
switch. Installation and inspection to be performed by qualified personnel.
Nameplates are located on cover and on the bottom of the transducer. Check
to be sure the third digit in each number is the same. If not, the unit should
not be used. (Refer to Figure 3).
IMPORTANT: All internal adjustments have been made at the factory. Any
adjustment, alteration or repair to the internal parts of the switch other than
stated herein voids all warranties. The signal setting adjustments required
are made by the adjusting nut on the outside of the switch.
Temperature Limitations
Ambient temperature limits are — 4_F(—20_C) to 140_F (60_C). To
determine fluid temperature limitations, see form No.V5771 for Pressure
Transducer catalog numbers and construction materials, then refer to chart
below.

Piping/Tubing (Pressure Transducer)
Adequate support of piping and proper mounting of switch should be made
to avoid excessive shock or vibration. To minimize the effect of vibration on
a switch, mount perpendicular to vibration. Connect piping or tubing to
switch at base of transducer. It is recommended that flexible tubing be used
whenever possible. Apply pipe compound sparingly to male pipe threads
only. If applied to female threads, it may enter the transducer and cause operational difficulty. Avoid pipe strain on switch by properly supporting and
aligning piping. When tightening pipe, do not use switch as a lever. Wrenches
applied to transducer body or piping are to be located as close as possible to
connection point.
IMPORTANT: For steam service, install a condensate loop (pigtail or steam
syphon tube) directly into the pressure transducer.
CAUTION: To avoid damage to the transducer body, DO NOT
OVERTIGHTEN PIPE CONNECTIONS. If TEFLON* tape, paste or similar lubricant is used, use extra care due to reduced friction.
IMPORTANT: To eliminate undesirable pressure fluctuations in the
system, install a surge suppressor.

Wiring
Thermal Well (Optional Feature)
Wiring must comply with local codes and the National Electrical Code. All
switch enclosures are provided with two 3/4I NPT conduit hubs with one
plugged when not in use. It is recommended that a flexible conduit connection be used. If rigid conduit is used, do not consider it or use it as a means
of support (mounting). For general purpose and watertight constructions,
the switch cover is removed by loosening two screws then twisting slightly and
lifting. For explosionproof construction, the cover unscrews. When explosionproof cover is replaced, torque cover to 135 ± 10 in---lbs [10,7 ± 1,1 Nm].
Use No. 14 AWG copper wire rated for 60_C minimum. All switches have a
grounding screw and clamp in the enclosure. For factory wired switch, black
lead is common, red lead is normally open, blue lead is normally closed, and
the green lead wire is a ground.
IMPORTANT: Electrical load must be within range stated on nameplate.
Failure to stay within the electrical range of the switch rating may result in
damage to or premature failure of electrical switch.
CAUTION: Do not exert excessive screw driver force on snap switch
when making terminal connections. When connections are made, be sure
there is no stress on the wire leads. Either condition may cause malfunction
of switch.

A thermal well may be used for capillary and bulb (remote) or direct probe (local)
temperature transducers. The thermal well affords protection for the sensing
bulb and allows removal of the sensing bulb while maintaining a pressure tight
vessel. When installing sensing bulb in thermal well, be sure that it is fully
inserted. Where a thermal well already exists, jam nuts may be obtained to adapt
the capillary and bulb to the existing thermal well. The existing thermal well must
be for a 3/8I diameter sensing bulb.
Union Connector (Optional Feature)
A union connector will allow direct mounting of the sensing bulb in the fluid
being controlled. Install union into piping connection before tightening
union onto bulb. For maximum performance, the bulb should be inserted in
the union connection so that the end of the sensing bulb is even with the end
of the union connector nut. Do not apply excessive torque when tightening
union connector nut.
Adjustment (Signal Setting) of Adjustable Deadband
Switch
To make adjustments, (signal setting) a 7/16I wrench and a pressure or
temperature gage (within suitable range) are required. If electrical
connection (to line of final application) of the switch is not desirable, a battery
powered test lamp or ohm meter may be used. Pressure or temperature
range scales should be used for initial signal setting. These will be accurate
within 5%. Loosen lock ring and turn adjusting nut until red line is even with
the desired range. For exact signal setting, proceed as follows:
WARNING: To prevent the possibility of personal
injury or property damage, turn off electrical power when
making permanent electrical connections to switch.
Adjustment (Signal Setting) of Normally Closed or
Normally Open Switch, Increasing Signal (Refer to Figure 2)
1. If the switch is in the line of final application when adjustment (signal
setting) is made, be sure switch can be test operated without affecting
other equipment.
2. Loosen lock ring on adjustment nut and turn low signal adjustment nut
full upwards and high signal adjustment full down using a 7/16I wrench.
CAUTION: Adjusting nut will turn easily until it hits a stop. Do not
over torque; over torquing may cause internal damage resulting in malfunction.
3. Remove switch cover to gain access to snap switch. See section on
Wiring for cover removal.

other equipment.
While in service, operate the switch (cycle between desired signals) at
least once a month to insure proper operation. If necessary, electrical
wiring and pipe connection should be made so that switch can be test operated without affecting other equipment.
S
2. Loosen lock ring on adjustment nuts and turn low signal adjustment nut
full upwards and high signal adjustment nut slightly beyond desired
actuation setting using a 7/16I wrench.
Periodic inspection of the switch, external surfaces only, should be carried out. Switch should be kept clean and free from paint, foreign matter, corrosion, icing, and freezing conditions.
S
Keep the medium entering the transducer as free as possible from dirt
and foreign material.
(Refer to Figure 2)
CAUTION: Adjustment nut will turn easily until it hits a stop. Do not
over torque; over torquing may cause internal damage resulting in malfunction.
3. Remove switch cover to gain access to snap switch. See section on
Wiring for cover removal.
4. Follow steps in chart below to make signal setting.

Causes of Improper Operation
Switch will not actuate or actuates and reactuates undesirable.
S
Incorrect Electrical Connection: Check leads to switch. Be sure they
are properly connected. Switch is marked NO for Normally Open, NC
for Normally Closed and C for Common.
S
Faulty Control Circuit: Check electrical power supply to switch. Check
for loose or blown fuses, open---circuited or grounded wires, loose connections at terminal block or switch. See nameplate for electrical rating
and range.
S
Incorrect Pressure: Check pressure in system with suitable pressure
gage. Pressure must be within range specified on nameplate.
S
Incorrect Adjustment: Check adjustment nuts for proper setting. Refer
to adjustment instructions.
S
External Leakage: Check to see that bolts (4) holding transducer to
pressure switch are properly torqued to 80 ± 10 in---lbs [9,0 ± 1,1 Nm].
If bolts are tight and leakage is still evident, replace transducer. Refer
to paragraph on Assembly of Switch Unit and Transducer Unit.
S
Excessive Vibration or Surges Causing Switch to Actuate and Reactuate: Check for fluctuations in system and install pressure surge suppressor. Check switch mounting and be sure there is no excessive vibration.
S
Incorrect Temperature: Check temperature in system with suitable
thermometer. Temperature must be within range specified on nameplate. Check location of capillary and bulb for incorrect mounting. Refer to paragraphs on Installation of Temperature Transducers.

5. Cycle between actuation and reactuation signals and make minor
adjustment to adjusting nuts as required to achieve the exact signal
settings.
If the operation of the switch cannot be corrected by the above means, the entire switch unit should be replaced or an authorized factory representative
consulted.
6. After settings have been made, tighten lock rings and make permanent
electrical connections.
Color Code Identification
Testing of Installation
If the adjustment of the switch has been made outside of the line of final application, the switch should be retested when installed in the line of final application. Follow adjustment instructions. Be sure switch can be test operated
without affecting other equipment.
MAINTENANCE
WARNING: To prevent the possibility of personal
injury or property damage, turn off electrical power and
depressurize switch unit before inspection or removal.
IMPORTANT: Switch is not field repairable. The switch must be returned
to the factory (Automatic Switch Company, Florham Park, New Jersey) or
serviced only by an authorized factory representative. Address all service
inquiries to Automatic Switch Company, 50 ---60 Hanover road, Florham
Park, New Jersey 07932, Valve Service Department. The only maintenance
which may be performed on the adjustable deadband switch is changing the
setting of the adjusting nuts and replacement of the transducer unit.
Replacement of transducer should be done only if external leakage is
evident.
