ECM Motor — The direct- drive motor is an X13
Electronically Commutated Motor (ECM). An ECM
motor contains electronic circuitry used to convert
single- phase line AC voltage into 3- phase DC voltage to
power the motor circuit. The motor circuit is a DC
brushless design with a permanent magnet rotor. On the
X13 ECM Motor design, the electronic circuitry is
integral to the motor assembly and cannot be serviced or
replaced separately.
208/230V units use a 230V motor. 460V units use a 230V
motor with a stepdown transformer (mounted on the end
of the fan housing, see Fig. 5). 575V units use a 460V
motor with an autotransformer. Motor power voltage is
connected to motor terminals L and N (see Fig. 6 and
Fig. 7); ground is connected at terminal G. The motor
power voltage is ALWAYS present; it is not switched off
by a motor contactor.

Selecting another speed:
C09261
1. Disconnect main power to the unit. Apply
lockout/tagout procedures.
2. Remove the default motor signal lead (VIO) from
terminal 1 at the motor communications terminal.
3. Reconnect the motor signal lead to the desired speed
(terminals 1 through 5).
4. Connect main power to the unit.
Evaluating motor speed — The X13 ECM Motor uses a
constant torque motor design. The motor speed is adjusted
by the motor control circuitry to maintain the programmed
shaft torque. Consequently there is no specific speed value
assigned to each control tap setting. At the Position 5 tap,
the motor speed is approximately 1050 RPM (17.5 r/s) but
varies depending on fan wheel loading.
460, 575-v Units
208/230-v Units
Fig. 7 - Direct- Drive Supply Fan Assembly
Motor “rocking” on start- up — When the motor first
starts, the rotor (and attached wheel) will “rock” back and
forth as the motor tests for rotational direction. Once the
correct rotational direction is determined by the motor
circuitry, the motor will ramp up to the specified speed.
The “rocking” is a normal operating characteristic of
ECM motors.
C09260
1. Disconnect main power to the unit.
2. Remove the motor power plug (including the control
BRN lead) and VIO control signal lead at the motor
terminals.
3. Restore main unit power.
4. Check for proper line voltage at motor power leads
BLK (at L terminal) and YEL (at N terminal). See
Table 2.

Belt
Check the belt condition and tension quarterly. Inspect the
belt for signs of cracking, fraying or glazing along the
inside surfaces. Check belt tension by using a spring- force
tool, such as Browning’s “Belt Tension Checker” (p/n:
1302546 or equivalent tool); tension should be 6- lbs at a
5/ - in (1.6 cm). deflection when measured at the
8
centerline of the belt span. This point is at the center of
the belt when measuring the distance between the motor
shaft and the blower shaft.
Replacing the X- 13 ECM Motor — Before removing
the ECM belly- band mounting ring from old motor:
1. Measure the distance from base of the motor shaft to
the edge of the mounting ring.
2. Remove the motor mounting band and transfer it to
the replacement motor.
3. Position the mounting band at the same distance that
was measured in Step 1.
4. Hand- tighten mounting bolt only. Do not tighten
securely at this time.
5. Insert the motor shaft into the fan wheel hub.
6. Securely tighten the three motor mount arms to the
support cushions and torque the arm mounting screws
to 60 in- lbs (6.8 Nm).
7. Center the fan wheel in the fan housing. Tighten the
fan wheel hub setscrew and torque to 120 in- lbs (13.6
Nm).
8. Ensure the motor terminals are located at a position
below the 3 o’clock position (see Fig. 5). Tighten the
motor belly- band bolt and torque to 80 in- lbs (9.0
Nm).
NOTE: Without the spring- tension tool, place a straight
edge across the belt surface at the pulleys, then push down
on the belt at mid- span using one finger until a 1/2 - in.
(1.3 cm) deflection is reached. See Fig. 9.
Adjust belt tension by loosening the motor mounting plate
front and rear bolts and sliding the plate toward the fan (to
reduce tension) or away from fan (to increase tension).
Ensure the blower shaft and the motor shaft are parallel to
each other (pulleys aligned). When finished, tighten all
bolts and torque to 65- 70 in- lb (7.4 to 7.9 Nm).
Supply Fan (Belt- Drive)
The belt- drive supply fan system consists of a
forward- curved centrifugal blower wheel on a solid shaft
with two concentric type bearings, one on each side of the
blower housing. A fixed- pitch driven pulley is attached to
the fan shaft and an adjustable- pitch driver pulley is on
the motor. The pulleys are connected using a V- belt. (See
Fig. 8.).

Replacing the Belt:
Fig. 10 - Supply- Fan Pulley Adjustment
As the pitch diameter is changed by adjusting the position
of the movable flange, the centerline on this pulley shifts
laterally (along the motor shaft). This creates a
requirement for a realignment of the pulleys after any
adjustment of the movable flange. Reset the belt tension
after each realignment.
Use the following steps to replace the V- belt. See Fig. 8.
1. Loosen the front and rear motor mounting plate bolts.
2. Push the motor and its mounting plate towards the
blower housing as close as possible to reduce the
center distance between fan shaft and motor shaft.
3. Remove the belt by gently lifting the old belt over
one of the pulleys.
4. Install the new belt by gently sliding the belt over
both pulleys and then sliding the motor and plate
away from the fan housing until proper tension is
achieved.
!
C07075
Inspect the condition of the motor pulley for signs of
wear. Glazing of the belt contact surfaces and erosion on
these surfaces are signs of improper belt tension and/or
belt slippage. Replace pulley if wear is excessive.
Changing the Fan Speed:
1. Shut off unit power supply. Use proper lockout/tagout
procedures.
2. Loosen belt by loosening fan motor mounting nuts.
(See Fig. 8.)
3. Loosen movable pulley flange setscrew. (See Fig. 10.)
4. Screw movable flange toward fixed flange to increase
speed and away from fixed flange to decrease speed.
Increasing fan speed increases load on motor. Do not
exceed the maximum specified speed.
5. Set movable flange at nearest keyway of pulley hub.
Tighten setscrew and torque to 65- 70 in- lb (7.4 to 7.9
Nm).
CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this CAUTION can result in
premature wear and damage to equipment.
Do not use a screwdriver or a pry bar to place the new
V- belt in the pulley groove. This can cause stress on
the V- belt and the pulley resulting in premature wear
on the V- belt and damage to the pulley.
Aligning Blower and Motor Pulleys:
1. Loosen blower pulley setscrews.
2. Slide blower pulley along blower shaft. Make angular
alignment by loosening motor mounting plate front
and rear bolts.
3. Tighten blower pulley setscrews and motor mounting
bolts. Torque bolts to 65- 70 in- lb (7.4 to 7.9 Nm).
4. Recheck belt tension.
5. Check the alignment of the pulleys, adjust if necessary.
6. Tighten all bolts and torque to 65- 70 in- lb (7.4 to 7.9
Nm).
7. Check the tension after a few hours of runtime and
re- adjust as required.
Adjustable- Pitch Pulley on Motor
Bearings
The motor pulley is an adjustable- pitch type that allows a
servicer to implement changes in the fan wheel speed to
match as- installed ductwork systems. The pulley consists
of a fixed flange side that faces the motor (secured to the
motor shaft) and a movable flange side that can be rotated
The fan system uses bearings featuring concentric split
locking collars. A Torx T- 25 socket head cap screw is
used to tighten the locking collars. Tighten the locking
collar by holding it tightly against the inner race of the
bearing. Tighten the socket head cap screw. Torque cap

Indoor Fan Speed System
The 2- Speed Fan motor system utilizes a Fan Speed
control board and Variable Frequency Drive (VFD) to
automatically adjust the indoor fan motor speed in
sequence with the unit’s ventilation, cooling and heating
operation. Per ASHRAE 90.1 2010 standard section
6.4.3.10.b, during the first stage of cooling operation the
2- Speed Fan motor system will adjust the fan motor to
provide two- thirds (2/3) of the design airflow rate for the
unit. When the call for the second stage of cooling is
required, the 2- Speed Fan motor system will allow the
design airflow rate for the unit established (100%). During
the heating mode, the 2- Speed Fan Motor system will
allow total design airflow rate (100%) operation. During
ventilation mode, the 2- Speed Fan Motor system will
operate the fan motor at 2/3 speed.

CAUTION
EQUIPMENT DAMAGE HAZARD
Failure to follow this CAUTION can result in
premature wear and damage to equipment.
Do not use a screwdriver or a pry bar to place the new
V- belt in the pulley groove. This can cause stress on
the V- belt and the pulley resulting in premature wear
on the V- belt and damage to the pulley.
7. Loosen the four mounting bracket bolts and lock
washers.
8. Remove four bolts, four flat washers, four lock
washers and four nuts attaching the motor mounting
When replacing the motor, also replace the external- tooth
lock washer (star washer) under the motor mounting base;
this is part of the motor grounding system. Ensure the

teeth on the lock washer are in contact with the motor’s
painted base. Tighten motor mounting bolts to 120  12
in- lbs.
Changing Fan Wheel Speed
581J
Changing fan wheel speed by changing pulleys: The
horsepower rating of the belt is primarily dictated by the
pitch diameter of the smaller pulley in the drive system
(typically the motor pulley in these units). Do not install a
replacement motor pulley with a smaller pitch diameter
than provided on the original factory pulley. Change fan
wheel speed by changing the fan pulley (larger pitch
diameter to reduce wheel speed, smaller pitch diameter to
increase wheel speed) or select a new system (both
pulleys and matching belt).
Before changing pulleys to increase fan wheel speed,
check the fan performance at the target speed and airflow
rate to determine new motor loading (bhp). Use the fan
performance tables or use the Packaged Rooftop Builder
software program. Confirm that the motor in this unit is
capable of operating at the new operating condition. Fan
shaft loading increases dramatically as wheel speed is
increased.
To reduce vibration, replace the motor’s adjustable pitch
pulley with a fixed pitch pulley (after the final airflow
balance adjustment). This will reduce the amount of
vibration generated by the motor/belt- drive system.

COOLING
Periodic cleaning with TotalineR environmentally sound
coil cleaner is essential to extend the life of coils. This
cleaner is available from Replacement Components
Division as part number P902- 0301 for a one gallon
container, and part number P902- 0305 for a 5 gallon
container. It is recommended that all coils, including
standard aluminum, pre- coated, copper/copper or
E- coated coils be cleaned with the Totaline
environmentally sound coil cleaner as described below.
Coil cleaning should be part of the unit’s regularly
scheduled maintenance procedures to ensure long life of
the coil. Failure to clean the coils may result in reduced
durability in the environment.
WARNING
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal
injury, death and/or equipment damage.
This system uses PuronR refrigerant which has
higher pressures than R- 22 and other refrigerants. No
other refrigerant may be used in this system. Gauge
set, hoses, and recovery system must be designed to
handle Puron refrigerant. If unsure about equipment,
consult the equipment manufacturer.
Avoid use of:
Condenser Coil
S coil brighteners
The condenser coil is fabricated with round tube copper
hairpins and plate fins of various materials and/or coatings
(see Model Number Format in the Appendix to identify
the materials provided in this unit). The coil may be
one- row or composite- type two- row. Composite two- row
coils are two single- row coils fabricated with a single
return bend end tubesheet.
581J
!
Routine Cleaning of Coil Surfaces
S acid cleaning prior to painting
S high pressure washers
S poor quality water for cleaning
Totaline environmentally sound coil cleaner is
nonflammable, hypo allergenic, non bacterial, and a
USDA accepted biodegradable agent that will not harm
the coil or surrounding components such as electrical
wiring, painted metal surfaces, or insulation. Use of
non- recommended coil cleaners is strongly discouraged
since coil and unit durability could be affected.
Condenser Coil Maintenance and Cleaning
Recommendation
Routine cleaning of coil surfaces is essential to maintain
proper operation of the unit. Elimination of contamination
and removal of harmful residues will greatly increase the
life of the coil and extend the life of the unit. The
following maintenance and cleaning procedures are
recommended as part of the routine maintenance activities
to extend the life of the coil.
One- Row Coil
Wash coil with commercial coil cleaner. It is not
necessary to remove top panel.
Two- Row Coils
Remove Surface Loaded Fibers
Clean coil as follows:
1. Turn off unit power, tag disconnect.
2. Remove top panel screws on condenser end of unit.
3. Remove condenser coil corner post. See Fig. 16. To
hold top panel open, place coil corner post between
top panel and center post. See Fig. 17.
Surface loaded fibers or dirt should be removed with a
vacuum cleaner. If a vacuum cleaner is not available, a
soft non- metallic bristle brush may be used. In either
case, the tool should be applied in the direction of the fins.
Coil surfaces can be easily damaged (fin edges can be
easily bent over and damage to the coating of a protected
coil) if the tool is applied across the fins.
NOTE: Use of a water stream, such as a garden hose,
against a surface loaded coil will drive the fibers and dirt
into the coil. This will make cleaning efforts more
difficult. Surface loaded fibers must be completely
removed prior to using low velocity clean water rinse.
Periodic Clean Water Rinse
A periodic clean water rinse is very beneficial for coils
that are applied in coastal or industrial environments.
However, it is very important that the water rinse is made
with a very low velocity water stream to avoid damaging
the fin edges. Monthly cleaning as described below is
recommended.
Fig. 16 - Cleaning Condenser Coil

C08205
CAUTION
581J
Fig. 17 - Propping Up Top Panel
C08206
4. Remove screws securing coil to compressor plate and
compressor access panel.
5. Remove fastener holding coil sections together at return end of condenser coil. Carefully separate the outer coil section 3 to 4 in. from the inner coil section.
See Fig. 18.
Fig. 18 - Separating Coil Sections
UNIT DAMAGE HAZARD
Failure to follow this caution may result in accelerated
corrosion of unit parts.
Harsh chemicals, household bleach or acid or basic
cleaners should not be used to clean outdoor or indoor
coils of any kind. These cleaners can be very difficult
to rinse out of the coil and can accelerate corrosion at
the fin/tube interface where dissimilar materials are in
contact. If there is dirt below the surface of the coil,
use the Totaline environmentally sound coil cleaner.
C08207
6. Use a water hose or other suitable equipment to flush
down between the 2 coil sections to remove dirt and
debris. Clean the outer surfaces with a stiff brush in
the normal manner.
7. Secure inner and outer coil rows together with a
field- supplied fastener.
8. Reposition the outer coil section and remove the coil
corner post from between the top panel and center
post. Reinstall the coil corner post and replace all
screws.
Totaline Environmentally Sound Coil Cleaner
Application Equipment
S 2- 1/2 gallon garden sprayer
S Water rinse with low velocity spray nozzle
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced
unit performance or unit shutdown.
High velocity water from a pressure washer, garden
hose, or compressed air should never be used to
clean a coil. The force of the water or air jet will
bend the fin edges and increase airside pressure drop.
Totaline Environmentally Sound Coil Cleaner
Application Instructions
1. Proper eye protection such as safety glasses is recommended during mixing and application.
2. Remove all surface loaded fibers and dirt with a vacuum cleaner as described above.
3. Thoroughly wet finned surfaces with clean water and
a low velocity garden hose, being careful not to bend
fins.
4. Mix Totaline environmentally sound coil cleaner in a
2- 1/2 gallon garden sprayer according to the instructions included with the cleaner. The optimum solution
temperature is 100_F.
NOTE: Do NOT USE water in excess of 130_F, as the
enzymatic activity will be destroyed.
5. Thoroughly apply Totaline environmentally sound
coil cleaner solution to all coil surfaces including
finned area, tube sheets and coil headers.
6. Hold garden sprayer nozzle close to finned areas and
apply cleaner with a vertical, up- and- down motion.
Avoid spraying in horizontal pattern to minimize potential for fin damage.
7. Ensure cleaner thoroughly penetrates deep into finned
areas.
8. Interior and exterior finned areas must be thoroughly
cleaned.
9. Finned surfaces should remain wet with cleaning
solution for 10 minutes.
10. Ensure surfaces are not allowed to dry before rinsing.
Reapplying cleaner as needed to ensure 10- minute
saturation is achieved.
11. Thoroughly rinse all surfaces with low velocity clean
water using downward rinsing motion of water spray
nozzle. Protect fins from damage from the spray
nozzle.
Evaporator Coil
Cleaning the Evaporator Coil
1. Turn unit power off. Install lockout tag. Remove
evaporator coil access panel.
2. If economizer or two- position damper is installed, remove economizer by disconnecting Molex plug and
removing mounting screws.
14
3. Slide filters out of unit.
4. Clean coil using a commercial coil cleaner or dishwasher detergent in a pressurized spray canister. Wash
both sides of coil and flush with clean water. For best
results, back- flush toward return- air section to remove foreign material. Flush condensate pan after
completion.
5. Reinstall economizer and filters.
6. Reconnect wiring.
7. Replace access panels.
5. Remove bulb from vapor tube inside cabinet.
6. Install the new TXV using a wrench and an additional
wrench on connections to prevent damage to tubing
while attaching TXV to distributor.
7. Attach the equalizer tube to the suction line. If the
coil has mechanical a connection, then use a wrench
and an additional wrench on connections to prevent
damage. If the coil has a brazed connection, use a file
or a tubing cutter to remove the mechanical flare nut
from the equalizer line. Then use a new coupling to
braze the equalizer line to the stub (previous equalizer
line) in suction line.
8. Attach TXV bulb in the same location where the original (in the sensing bulb indent) was when it was removed, using the supplied bulb clamps. See Fig. 19.
THERMOSTATIC EXPANSION
VALVE (TXV)
581J
All 581J’s have a factory installed nonadjustable
thermostatic expansion valve (TXV). The TXV will be a
bi-flow, bleed port expansion valve with an external
equalizer. TXVs are specifically designed to operate with
PuronR or R-22 refrigerant, use only factory authorized
TXVs. Do not interchange Puron and R-22 TXVs.
TXV Operation
THERMAL EXPANSION
(TXV) VALVE
The TXV is a metering device that is used in air
conditioning and heat pump systems to adjust to the
changing load conditions by maintaining a preset
superheat temperature at the outlet of the evaporator coil.
The volume of refrigerant metered through the valve seat
is dependent upon the following:
1. Superheat temperature is sensed by cap tube sensing
bulb on suction tube at outlet of evaporator coil. This
temperature is converted into pressure by refrigerant
in the bulb pushing downward on the diaphragm
which opens the valve using the push rods.
2. The suction pressure at the outlet of the evaporator
coil is transferred through the external equalizer tube
to the underside of the diaphragm.
3. The pin is spring loaded, which exerts pressure on the
underside of the diaphragm. Therefore, the bulb pressure works against the spring pressure and evaporator
suction pressure to open the valve. If the load increases, the temperature increases at the bulb, which
increases the pressure on the top side of the diaphragm. This opens the valve and increases the flow
of refrigerant. The increased refrigerant flow causes
the leaving evaporator temperature to decrease. This
lowers the pressure on the diaphragm and closes the
pin. The refrigerant flow is effectively stabilized to
the load demand with negligible change in superheat.

10. Sweat the inlet of TXV marked “IN” to the liquid
line. Avoid excessive heat which could damage the
TXV valve.
Refrigerant System Pressure Access Ports
Replacing TXV
There are two access ports in the system - on the suction
tube near the compressor and on the discharge tube near
the compressor. These are brass fittings with black plastic
caps. The hose connection fittings are standard 1/4 SAE
male flare couplings.
1. Recover refrigerant.
2. Remove TXV support clamp using a 5/l6-in. nut
driver.
3. Remove TXV using a wrench and an additional
wrench on connections to prevent damage to tubing.
4. Remove equalizer tube from suction line of coil. Use
file or tubing cutter to cut brazed equalizer line
approximately 2 inches above suction tube.
The brass fittings are two- piece High Flow valves, with a
receptacle base brazed to the tubing and an integral
spring- closed check valve core screwed into the base. See
Fig. 20. This check valve is permanently assembled into
this core body and cannot be serviced separately; replace
15
the entire core body if necessary. Service tools are
available from RCD that allow the replacement of the
check valve core without having to recover the entire
system refrigerant charge. Apply compressor refrigerant
oil to the check valve core’s bottom o- ring. Install the
fitting body with 96  10 in- lbs (10.85  1.1 Nm) of
torque; do not overtighten.
PURONR (R- 410A) REFRIGERANT
581J
This unit is designed for use with Puron (R- 410A)
refrigerant. Do not use any other refrigerant in this
system. Puron (R- 410A) refrigerant is provided in pink
(rose) colored cylinders.
Puron (R- 410A) refrigerant is provided in pink (rose)
colored cylinders. These cylinders are available with and
without dip tubes; cylinders with dip tubes will have a
label indicating this feature. For a cylinder with a dip
tube, place the cylinder in the upright position (access
valve at the top) when removing liquid refrigerant for
charging. For a cylinder without a dip tube, invert the
cylinder (access valve on the bottom) when removing
liquid refrigerant.
Because Puron (R- 410A) refrigerant is a blend, it is
strongly recommended that refrigerant always be removed
from the cylinder as a liquid. Admit liquid refrigerant into
the system in the discharge line. If adding refrigerant into
the suction line, use a commercial metering/expansion
device at the gauge manifold; remove liquid from the
cylinder, pass it through the metering device at the gauge
set and then pass it into the suction line as a vapor. Do not
remove Puron (R- 410A) refrigerant from the cylinder as a
vapor.
Refrigerant Charge
Amount of refrigerant charge is listed on the unit’s
nameplate. Refer to Bryant GTAC2- 5 Charging,
Recovery, Recycling and Reclamation training manual
and the following procedures.
Unit panels must be in place when unit is operating during
the charging procedure.
No Charge
Use standard evacuating techniques. After evacuating
system, weigh in the specified amount of refrigerant.
Low- Charge Cooling
Using Cooling Charging Charts, Fig. 21 through Fig. 28,
vary refrigerant until the conditions of the appropriate
chart are met. Note the charging charts are different from
type normally used. Charts are based on charging the units
to the correct sub- cooling for the various operating
conditions. Accurate pressure gauge and temperature
sensing device are required. Connect the pressure gauge to
the service port on the liquid line. Mount the temperature
sensing device on the liquid line and insulate it so that
outdoor ambient temperature does not affect the reading.
Indoor- air cfm must be within the normal operating range
of the unit.

INSTALLATION SITE DAMAGE
Failure to follow this caution can result in damage to
equipment location site.
The compressor is charged with the correct amount of oil
at the factory.
581J
CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in damage to
components.
The compressor is in a PuronR refrigerant system and
uses a polyolester (POE) oil. This oil is extremely
hygroscopic, meaning it absorbs water readily. POE
oils can absorb 15 times as much water as other oils
designed for HCFC and CFC refrigerants. Avoid
exposure of the oil to the atmosphere.
Puron (R- 410A) refrigerant contains polyolester
(POE) oil that can damage the roof membrane.
Caution should be taken to prevent POE oil from
spilling onto the roof surface.
The factory also recommends that the suction and
discharge lines be cut with a tubing cutter instead of
using a torch to remove brazed fittings.

WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this
warning could result in
death, serious personal
injury and/or property
damage.
Never use non- certified refrigerants in this product.
Non- certified refrigerants could contain contaminates
that could lead to unsafe operating conditions. Use
ONLY refrigerants that conform to AHRI Standard
700.
Replacing Compressor
NOTE: Only factory- trained service technicians should
remove and replace compressor units.
EQUIPMENT DAMAGE
Failure to follow this caution can result in equipment
damage.
Scroll compressors can only compress refrigerant if
rotating in the right direction. Reverse rotation for
extended times can result in internal damage to the
compressor. Scroll compressors are sealed units and
cannot be repaired on site location.
NOTE: When the compressor is rotating in the wrong
direction, the unit makes an elevated level of noise and
does not provide cooling.
On 3- phase units with scroll compressors, it is important
to be certain compressor is rotating in the proper
direction. To determine whether or not compressor is
rotating in the proper direction:
1. Connect service gauges to suction and discharge
pressure fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge
pressure should rise, as is normal on any start- up.
NOTE: If the suction pressure does not drop and the
discharge pressure does not rise to normal levels:
4. Note that the evaporator fan is probably also rotating
in the wrong direction.
5. Turn off power to the unit.
6. Reverse any two of the three unit power leads.
7. Reapply electrical power to the compressor.
8. The suction pressure should drop and the discharge
pressure should rise which is normal for scroll
compressors on start- up.
9. Replace compressor if suction/discharge pressures are
not within specifications for the specific compressor.
The suction and discharge pressure levels should now
move to their normal start- up levels.
22
Filter Drier
Replace whenever refrigerant system is exposed to
atmosphere. Only use factory specified liquid- line filter
driers with working pressures no less than 650 psig. Do
not install a suction- line filter drier in liquid line. A
liquid- line filter drier designed for use with Puron
refrigerant is required on every unit.

Duty Cycle: The unit- powered convenience outlet has a
duty cycle limitation. The transformer is intended to
provide power on an intermittent basis for service tools,
lamps, etc; it is not intended to provide 15A loading for
continuous duty loads (such as electric heaters for
overnight use). Observe a 50% limit on circuit loading
above 8A (i.e., limit loads exceeding 8A to 30 minutes of
operation every hour).
Maintenance: Periodically test the GFCI receptacle by
pressing the TEST button on the face of the receptacle.
This should cause the internal circuit of the receptacle to
trip and open the receptacle. Check for proper grounding
wires and power line phasing if the GFCI receptacle does
not trip as required. Press the RESET button to clear the
tripped condition.
The smoke detector system consists of a four- wire
controller and one or two sensors. Its primary function is
to shut down the rooftop unit in order to prevent smoke
from circulating throughout the building. It is not to be
used as a life saving device.
Controller
The controller (see Fig. 33) includes a controller housing,
a printed circuit board, and a clear plastic cover. The
controller can be connected to one or two compatible duct
smoke sensors. The clear plastic cover is secured to the
housing with a single captive screw for easy access to the
wiring terminals. The controller has three LEDs (for
Power, Trouble and Alarm) and a manual test/reset button
(on the cover face).

The Smoke Detector Sensor (see Fig. 34) includes a
plastic housing, a printed circuit board, a clear plastic
cover, a sampling tube inlet and an exhaust tube. The
sampling tube (when used) and exhaust tube are attached
during installation. The sampling tube varies in length
depending on the size of the rooftop unit. The clear plastic
cover permits visual inspections without having to
disassemble the sensor. The cover attaches to the sensor
housing using four captive screws and forms an airtight
chamber around the sensing electronics. Each sensor
includes a harness with an RJ45 terminal for connecting to
the controller. Each sensor has four LEDs (for Power,
Trouble, Alarm and Dirty) and a manual test/reset button
(on the left- side of the housing).

Smoke Detector Locations
Supply Air: The Supply Air Smoke Detector Sensor is
located to the left of the unit’s indoor (supply) fan. See
Fig. 35. Access is through the fan access panel. There is
no sampling tube used at this location. The sampling tube
inlet extends through the side plate of the fan housing
(into a high pressure area). The controller is located on a
bracket to the right of the return filter, accessed through
the lift- off filter panel.
The sensor uses a process called differential sensing to
prevent gradual environmental changes from triggering
false alarms. A rapid change in environmental conditions,
such as smoke from a fire, causes the sensor to signal an
alarm state but dust and debris accumulated over time
does not.
The difference in air pressure between the two tubes pulls
the sampled air through the sensing chamber. When a
sufficient amount of smoke is detected in the sensing
chamber, the sensor signals an alarm state and the
controller automatically takes the appropriate action to
shut down fans and blowers, change over air handling
systems, notify the fire alarm control panel, etc.
For installations using two sensors, the duct smoke
detector does not differentiate which sensor signals an
alarm or trouble condition.

FIOP Smoke Detector Wiring and Response
Highlight D: On smoke alarm condition, the smoke
detector NO Alarm contact will close, supplying 24- v
power to GRA conductor.
All units: FIOP smoke detector is configured to
automatically shut down all unit operations when a smoke
condition is detected. See Fig. 40, Smoke Detector
Wiring.
Highlight E: GRA lead at Smoke Alarm input on LCTB
provides 24- v signal to FIOP DDC control.
RTU- OPEN: The 24- v signal is conveyed to
RTU- OPEN - J1- 10 input terminal. This signal initiates
the FSD sequence by the RTU- OPEN control. FSD status
is reported to connected BAS network.
Highlight A: JMP 3 is factory- cut, transferring unit
control to smoke detector.
Highlight B: Smoke detector NC contact set will open on
smoke alarm condition, de- energizing the ORN
conductor.
Highlight C: 24V power signal using the ORN lead is
removed at the Smoke Detector input on LCTB; all unit
operations cease immediately.

Fuel Types and Pressures
General
Natural Gas
The heat exchanger system consists of a gas valve feeding
multiple in- shot burners off a manifold. The burners fire
into matching primary tubes. The primary tubes discharge
into combustion plenum where gas flow converges into
secondary tubes. The secondary tubes exit into the
induced draft fan wheel inlet. The induced fan wheel
discharges into a flue passage and flue gases exit out a
flue hood on the side of the unit. The induced draft fan
motor includes a Hall Effect sensor circuit that confirms
adequate wheel speed through the Integrated Gas Control
(IGC) board. Safety switches include a Rollout Switch (at
the top of the burner compartment) and a limit switch
(mounted through the fan deck, over the tubes). (See Fig.

Orifice Replacement
This unit uses orifice type LH32RFnnn (where nnn
indicates orifice reference size). When replacing unit
orifices, order the necessary parts through RCD. See Table
15 for available orifice sizes. See Table 16 and Table 17
for orifice sizes for Natural Gas and LP fuel usage at
various elevations above sea level.
Ensure each replacement orifice is tight as its threads into
the manifold pipe and the orifice projection does not
exceed maximum value. See Fig. 49.

Minimum heating entering air temperature
Troubleshooting Heating System
When operating on first stage heating, the minimum
temperature of air entering the dimpled heat exchanger is
50_F continuous and 45_F intermittent for standard heat
exchangers and 40_F continuous and 35_F intermittent for
stainless steel heat exchangers. To operate at lower
mixed- air temperatures, a field- supplied outdoor- air
thermostat must be used to initiate both stages of heat
when the temperature is below the minimum required
temperature to ensure full fire operation. Wire the
outdoor- air thermostat OALT (part no. HH22AG106) in
series with the second stage gas valve. See Fig. 58. Set the
outdoor- air thermostat at 35_F for stainless steel heat
exchangers or 45_F for standard heat exchangers. This
temperature setting will bring on the second stage of heat
whenever the ambient temperature is below the thermostat
setpoint. Indoor comfort may be compromised when
heating is initiated using low entering air temperatures
with insufficient heating temperature rise.
Refer to Table 20 and Table 21 for additional
troubleshooting topics.

RTU- OPEN CONTROL SYSTEM
The RTU Open controller is an integrated component of the
Bryant rooftop unit. Its internal application programming
provides optimum performance and energy efficiency. RTU
Open enables the unit to run in 100% stand- alone control
mode, or a Third Party Building Automation System (BAS).
On- board DIP switches allow you to select your protocol
(and baud rate) of choice among the four most popular
protocols in use today: BACnet, Modbus, Johnson N2 and
LonWorks.
The RTU Open control is factory- mounted in the unit’s
main control box, to the left of the Light Commercial
Terminal Board (LCTB). Factory wiring is completed
through harnesses connected to the LCTB. Field
connections for RTU Open sensors will be made at the
Phoenix connectors on the RTU Open board. The
factory- installed RTU Open control includes the
supply- air temperature (SAT) sensor. The outdoor air
temperature (OAT) sensor is included in the
FIOP/accessory EconoMi$er2 package.
SENSORY/ACCESSORY
INSTALLATION
There are a variety of sensors and accessories available
for the RTU-OPEN. Some of these can be factory or field
48
installed, while others are only field installable. The
RTU-OPEN controller may also require connection to a
building network system or building zoning system. All
field control wiring that connects to the RTU-OPEN must
be routed through the raceway built into the corner post of
the unit or secured to the unit control box with electrical
conduit. The unit raceway provides the UL required
clearance between high and low-voltage wiring. Pass the
control wires through the hole provided in the corner post,
then feed the wires thorough the raceway to the
RTU-OPEN. Connect the wires to the removable Phoenix
connectors and then reconnect the connectors to the board.
IMPORTANT: Refer to the specific sensor or accessory
instructions for its proper installation and for rooftop unit
installation refer to base unit installation instructions and
the unit’s wiring diagrams.
WARNING

end” and is sealed from moisture.
Supply Air Temperature (SAT) Sensor
The supply air temperature sensor is a 3 K thermistor
located at the inlet of the indoor fan. See Fig. 65. This
sensor is factory installed. The operating range of
temperature measurement is 0 to 158_F (- 18_ to 70_C).
See Table 65 for sensor temperature/resistance values.
Outdoor Air Lockout Sensor
The EconoMi$er IV is equipped with an ambient
temperature lockout switch located in the outdoor
airstream which is used to lock out the compressors below
a 42_F (6_C) ambient temperature. See Fig. 60.
EconoMi$er IV Control Modes
IMPORTANT: The optional EconoMi$er2 does not include
a controller. The EconoMi$er2 is operated by a 4 to 20
mA signal from an existing field-supplied controller. See
Fig. 61 for wiring information.
Determine the EconoMi$er IV control mode before set up
of the control. Some modes of operation may require
different sensors. The EconoMi$er IV is supplied from the
53
FLOW IN CUBIC FEET PER MINUTE (cfm)
factory with a supply- air temperature sensor and an
outdoor- air temperature sensor. This allows for operation
of the EconoMi$er IV with outdoor air dry bulb
changeover control. Additional accessories can be added
to allow for different types of changeover control and
operation of the EconoMi$er IV and unit.
The standard controller is shipped from the factory
configured for outdoor dry bulb changeover control. The
outdoor air and supply air temperature sensors are
included as standard. For this control mode, the outdoor
temperature is compared to an adjustable setpoint selected
on the control. If the outdoor-air temperature is above the
setpoint, the EconoMi$er IV will adjust the outside air
dampers to minimum position. If the outdoor-air
temperature is below the setpoint, the position of the
outside air dampers will be controlled to provided free
cooling using outdoor air. When in this mode, the LED
next to the free cooling setpoint potentiometer will be on.
The changeover temperature setpoint is controlled by the
free cooling setpoint potentiometer located on the control.
See Fig. 66. The scale on the potentiometer is A, B, C,
and D. See Fig. 71 for the corresponding temperature
changeover values.

Differential Enthalpy Control
For enthalpy control, accessory enthalpy sensor (p/n:
HH57AC078) is required. Replace the standard outdoor
dry bulb temperature sensor with the accessory enthalpy
sensor in the same mounting location. See Fig. 73. When
the outdoor air enthalpy rises above the outdoor enthalpy
changeover setpoint, the outdoor-air damper moves to its
minimum position. The outdoor enthalpy changeover
setpoint is set with the outdoor enthalpy setpoint
potentiometer on the EconoMi$er IV controller. The
setpoints are A, B, C, and D. See Fig. 74. The
factory-installed 620-ohm jumper must be in place across
terminals SR and SR+ on the EconoMi$er IV controller.
For differential enthalpy control, the EconoMi$er IV
controller uses two enthalpy sensors (HH57AC078 and
CRENTDIF004A00), one in the outside air and one in the
return air duct. The EconoMi$er IV controller compares
the outdoor air enthalpy to the return air enthalpy to
determine EconoMi$er IV use. The controller selects the
lower enthalpy air (return or outdoor) for cooling. For
example, when the outdoor air has a lower enthalpy than
the return air, the EconoMi$er IV opens to bring in
outdoor air for free cooling.
Replace the standard outside air dry bulb temperature
sensor with the accessory enthalpy sensor in the same
mounting location. See Fig. 61. Mount the return air
enthalpy sensor in the return air duct. See Fig. 69. Wiring
is provided in the EconoMi$er IV wiring harness. See Fig.
62. The outdoor enthalpy changeover setpoint is set with
the outdoor enthalpy setpoint potentiometer on the
EconoMi$er IV controller. When using this mode of
changeover control, turn the enthalpy setpoint
potentiometer fully clockwise to the D setting.

Indoor Air Quality (IAQ) Sensor Input
The IAQ input can be used for demand control ventilation
control based on the level of CO2 measured in the space
or return air duct.
Mount the accessory IAQ sensor according to
manufacturer specifications. The IAQ sensor should be
wired to the AQ and AQ1 terminals of the controller.
Adjust the DCV potentiometers to correspond to the DCV
voltage output of the indoor air quality sensor at the
user-determined setpoint. See Fig. 72.

C06039
Fig. 72 - CO2 Sensor Maximum Range Settings
If a separate field-supplied transformer is used to power
the IAQ sensor, the sensor must not be grounded or the
EconoMi$er IV control board will be damaged.
When using demand ventilation, the minimum damper
position represents the minimum ventilation position for
VOC (volatile
organic
compounds)
ventilation
requirements. The maximum demand ventilation position
is used for fully occupied ventilation.
When demand ventilation control is not being used, the
minimum position potentiometer should be used to set the
occupied ventilation position. The maximum demand
ventilation position should be turned fully clockwise.
Exhaust Setpoint Adjustment
The exhaust setpoint will determine when the exhaust fan
runs based on damper position (if accessory power
exhaust is installed). The setpoint is modified with the
Exhaust Fan Setpoint (EXH SET) potentiometer. See Fig.
66. The setpoint represents the damper position above
which the exhaust fans will be turned on. When there is a
call for exhaust, the EconoMi$er IV controller provides a
45  15 second delay before exhaust fan activation to
allow the dampers to open. This delay allows the damper
to reach the appropriate position to avoid unnecessary fan
overload.
Minimum Position Control
There is a minimum damper position potentiometer on the
EconoMi$er IV controller. See Fig. 66. The minimum
damper position maintains the minimum airflow into the
building during the occupied period.
When using demand ventilation, the minimum damper
position represents the minimum ventilation position for
Volatile Organic Compound (VOC) ventilation
requirements. The maximum demand ventilation position
is used for fully occupied ventilation.
When demand ventilation control is not being used, the
minimum position potentiometer should be used to set the
occupied ventilation position. The maximum demand
ventilation position should be turned fully clockwise.
Adjust the minimum position potentiometer to allow the
minimum amount of outdoor air, as required by local
codes, to enter the building. Make minimum position
adjustments with at least 10_F temperature difference
between the outdoor and return-air temperatures.
To determine the minimum position setting, perform the
following procedure:
1. Calculate the appropriate mixed air temperature
using the following formula:
(TO x
OA + (TR
)
100
x
RA
) =TM
100
TO = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature
RA = Percent of Return Air
TM = Mixed-Air Temperature
As an example, if local codes require 10% outdoor
air during occupied conditions, outdoor-air
temperature is 60_F, and return-air temperature is
75_F.
(60 x .10) + (75 x .90) = 73.5_F
2. Disconnect the supply air sensor from terminals T
and T1.
3. Ensure that the factory-installed jumper is in place
across terminals P and P1. If remote damper
positioning is being used, make sure that the
terminals are wired according to Fig. 52 and that the
minimum position potentiometer is turned fully
clockwise.
4. Connect 24 vac across terminals TR and TR1.
5. Carefully
adjust
the
minimum
position
potentiometer until the measured mixed air
temperature matches the calculated value.
6. Reconnect the supply air sensor to terminals T and
T1.
Remote control of the EconoMi$er IV damper is desirable
when requiring additional temporary ventilation. If a
field-supplied remote potentiometer (Honeywell p/n:
S963B1128) is wired to the EconoMi$er IV controller, the
minimum position of the damper can be controlled from a
remote location.
To control the minimum damper position remotely,
remove the factory-installed jumper on the P and P1
terminals on the EconoMi$er IV controller. Wire the
field-supplied potentiometer to the P and P1 terminals on
the EconoMi$er IV controller. (See Fig. 71.)
Damper Movement
Damper movement from full open to full closed (or vice
versa) takes 21/2 minutes.
56
TM = Mixed-Air Temperature
Once base ventilation has been determined, set the
minimum damper position potentiometer to the correct
position.
The same equation can be used to determine the occupied
or maximum ventilation rate to the building. For example,
an output of 3.6 volts to the actuator provides a base
ventilation rate of 5% and an output of 6.7 volts provides
the maximum ventilation rate of 20% (or base plus 15 cfm
per person). Use Fig. 72 to determine the maximum
setting of the CO2 sensor. For example, an 1100 ppm
setpoint relates to a 15 cfm per person design. Use the
1100 ppm curve on Fig. 72 to find the point when the CO2
sensor output will be 6.7 volts. Line up the point on the
graph with the left side of the chart to determine that the
range configuration for the CO2 sensor should be 1800
ppm. The EconoMi$er IV controller will output the 6.7
volts from the CO2 sensor to the actuator when the CO2
concentration in the space is at 1100 ppm. The DCV
setpoint may be left at 2 volts since the CO2 sensor
voltage will be ignored by the EconoMi$er IV controller
until it rises above the 3.6 volt setting of the minimum
position potentiometer.
Once the fully occupied damper position has been
determined, set the maximum damper demand control
ventilation potentiometer to this position. Do not set to the
maximum position as this can result in over-ventilation to
the space and potential high humidity levels.
The EconoMi$er IV control works with conventional
thermostats that have a Y1 (cool stage 1), Y2 (cool stage
2), W1 (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er IV control does not support space
temperature sensors. Connections are made at the
thermostat terminal connection board located in the main
control box.
Occupancy Control
The factory default configuration for the EconoMi$er IV
control is occupied mode. Occupied status is provided by
the black jumper from terminal TR to terminal N. When
unoccupied mode is desired, install a field- supplied
timeclock function in place of the jumper between TR and
N. When the timeclock contacts are closed, the
EconoMi$er IV control will be in occupied mode. When
the timeclock contacts are open (removing the 24V signal
from terminal N), the EconoMi$er IV will be in
unoccupied mode.
Demand Control Ventilation (DCV)
When using the EconoMi$er IV for demand controlled
ventilation, there are some equipment selection criteria
which should be considered. When selecting the heat
capacity and cool capacity of the equipment, the
maximum ventilation rate must be evaluated for design
conditions. The maximum damper position must be
calculated to provide the desired fresh air.
Typically the maximum ventilation rate will be about 5 to
10% more than the typical cfm required per person, using
normal outside air design criteria.
A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied
occupancy, and equipment that cannot exceed the required
ventilation rate at design conditions. Exceeding the
required ventilation rate means the equipment can
condition air at a maximum ventilation rate that is greater
than the required ventilation rate for maximum
occupancy. A proportional-anticipatory strategy will cause
the fresh air supplied to increase as the room CO2 level
increases even though the CO2 setpoint has not been
reached. By the time the CO2 level reaches the setpoint,
the damper will be at maximum ventilation and should
maintain the setpoint.
In order to have the CO2 sensor control the economizer
damper in this manner, first determine the damper voltage
output for minimum or base ventilation. Base ventilation
is the ventilation required to remove contaminants during
unoccupied periods. The following equation may be used
to determine the percent of outside air entering the
building for a given damper position. For best results there
should be at least a 10 degree difference in outside and
return-air temperatures.

START- UP, GENERAL
Unit Preparation
Make sure that unit has been installed in accordance with
installation instructions and applicable codes.
IMPORTANT: Follow the base unit’s start-up sequence
as described in the unit’s installation instructions:
In addition to the base unit start-up, there are a few steps
needed to properly start-up the controls. RTU-OPEN’s
Service Test function should be used to assist in the base
unit start-up and also allows verification of output
operation. Controller configuration is also part of start-up.
This is especially important when field accessories have
been added to the unit. The factory pre-configures options
installed at the factory. There may also be additional
installation steps or inspection required during the start-up
process.
Additional Installation/Inspection
Inspect the field installed accessories for proper
installation, making note of which ones do or do not
require configuration changes. Inspect the RTU-OPEN’s
Alarms for initial insight to any potential issues. Refer to
the following manual: “Controls, Start- up, Operation and
Troubleshooting Instructions.” Inspect the SAT sensor for
60
or remove compressor hold down bolts.
relocation as intended during installation. Inspect special
wiring as directed below.
Internal Wiring
Gas Piping
Check all electrical connections in unit control boxes.
Tighten as required.
Check gas piping for leaks.
WARNING
Refrigerant Service Ports
Each unit system has two 1/4” SAE flare (with check
valves) service ports: one on the suction line, and one on
the compressor discharge line. Be sure that caps on the
ports are tight.
FIRE, EXPLOSION HAZARD
Failure to follow this
warning could result in
death, serious personal
injury and/or property
damage.
Disconnect gas piping from unit when pressure testing
at pressure greater than 0.5 psig. Pressures greater than
0.5 psig will cause gas valve damage resulting in hazardous condition. If gas valve is subjected to pressure
greater than 0.5 psig, it must be replaced before use.
When pressure testing field-supplied gas piping at
pressures of 0.5 psig or less, a unit connected to such
piping must be isolated by closing the manual gas
valve(s).
Compressor Rotation
On 3- phase units with scroll compressors, it is important
to be certain compressor is rotating in the proper
direction. To determine whether or not compressor is
rotating in the proper direction:
1. Connect service gauges to suction and discharge pressure fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge
pressure should rise, as is normal on any start- up.
If the suction pressure does not drop and the discharge
pressure does not rise to normal levels:
!
4. Note that the evaporator fan is probably also rotating
in the wrong direction.
5. Turn off power to the unit and install lockout tag.
6. Reverse any two of the unit power leads.
7. Re- energize to the compressor. Check pressures.
WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in
personal injury, death and/or property damage.
Refer to the User’s Information Manual provided
with this unit for more details.
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
What to do if you smell gas:
DO NOT try to light any appliance.
DO NOT touch any electrical switch, or use any
phone in your building.
IMMEDIATELY call your gas supplier from a
neighbor’s phone. Follow the gas supplier’s
instructions.
If you cannot reach your gas supplier, call the fire
department.
The suction and discharge pressure levels should now
move to their normal start- up levels.
NOTE: When the compressor is rotating in the wrong
direction, the unit will make an elevated level of noise
and will not provide cooling.
Cooling
Set space thermostat to OFF position. To start unit, turn on
main power supply. Set system selector switch at COOL
position and fan switch at AUTO. position. Adjust
thermostat to a setting below room temperature.
Compressor starts on closure of contactor.
Check unit charge. Refer to Refrigerant Charge section.
Reset thermostat at a position above room temperature.
Compressor will shut off. Evaporator fan will shut off
after a 30- second delay.
Return- Air Filters
To shut off unit, set system selector switch at OFF
position. Resetting thermostat at a position above room
temperature shuts unit off temporarily until space
temperature exceeds thermostat setting.
Ensure correct filters are installed in unit (see Appendix II
- Physical Data). Do not operate unit without return- air
filters.
Outdoor- Air Inlet Screens
Main Burners
Outdoor- air inlet screen must be in place before operating
unit.
Main burners are factory set and should require no
adjustment.
Compressor Mounting
To check ignition of main burners and heating controls,
move thermostat setpoint above room temperature and
Compressors are internally spring mounted. Do not loosen
61

!
verify that the burners light and evaporator fan is
energized. Check heating effect, then lower the thermostat
setting below the room temperature and verify that the
burners and evaporator fan turn off.
Refer to Tables 16- 19 for the correct orifice to use at high
altitudes.
581J
Heating
1. Purge gas supply line of air by opening union ahead
of the gas valve. If gas odor is detected, tighten union
and wait 5 minutes before proceeding.
2. Turn on electrical supply and manual gas valve.
3. Set system switch selector at HEAT position and fan
switch at AUTO. or ON position. Set heating temperature lever above room temperature.
4. The induced- draft motor will start.
5. After a call for heating, the main burners should light
within 5 seconds. If the burner does not light, then
there is a 22- second delay before another 5- second
try. If the burner still does not light, the time delay is
repeated. If the burner does not light within 15
minutes, there is a lockout. To reset the control, break
the 24 v power to W1.
6. The evaporator- fan motor will turn on 45 seconds
after burner ignition.
7. The evaporator- fan motor will turn off in 45 seconds
after the thermostat temperature is satisfied.
8. Adjust airflow to obtain a temperature rise within the
range specified on the unit nameplate.
NOTE: The default value for the evaporator- fan motor
on/off delay is 45 seconds. The Integrated Gas Unit
Controller (IGC) modifies this value when abnormal limit
switch cycles occur. Based upon unit operating conditions,
the on delay can be reduced to 0 seconds and the off delay
can be extended to 180 seconds. When one flash of the
LED is observed, the evaporator- fan on/off delay has
been modified.
The evaporator- fan off delay can also be modified. Once
the call for heating has ended, there is a 10- minute period
during which the modification can occur. If the limit
switch trips during this period, the evaporator- fan off
delay will increase by 15 seconds. A maximum of 9 trips
can occur, extending the evaporator- fan off delay to 180
seconds.
To restore the original default value, reset the power to the
unit.
To shut off unit, set system selector switch at OFF
position. Resetting heating selector lever below room
temperature will temporarily shut unit off until space
temperature falls below thermostat setting.
Ventilation (Continuous Fan)
Set fan and system selector switches at ON and OFF
positions, respectively. Evaporator fan operates
continuously to provide constant air circulation. When the
evaporator- fan selector switch is turned to the OFF
position, there is a 30- second delay before the fan turns
off.
START- UP, RTU- OPEN CONTROLS
NOTICE
SET- UP INSTRUCTIONS
Refer to the following manuals for additional
installation, wiring and troubleshooting information
for the RTU- OPEN Controller.: “Controls, Start- up,
Operation and Troubleshooting Instructions,” “RTU
Open Installation and Start- up Guide” and
“RTU- Open Integration Guide”. Have a copy of these
manuals available at unit start- up.
If the limit switch trips at the start of the heating cycle
during the evaporator on delay, the time period of the on
delay for the next cycle will be 5 seconds less than the
time at which the switch tripped. (Example: If the limit
switch trips at 30 seconds, the evaporator- fan on delay for
the next cycle will occur at 25 seconds.) To prevent
short- cycling, a 5- second reduction will only occur if a
minimum of 10 minutes has elapsed since the last call for
heating.
