mechanical and electrical components. Only trained and qualified
personnel should install, repair, or service this equipment.
Untrained personnel can perform basic maintenance functions such
as cleaning and replacing air filters. All other operations must be
performed by trained service personnel. When working on this
equipment, observe precautions in the literature, on tags, and on
labels attached to or shipped with the unit and other safety
precautions that may apply.
Follow all safety codes. Installation must be in compliance with
local and national building codes. Wear safety glasses, protective
clothing, and work gloves. Have fire extinguisher available. Read
these instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit.
Recognizesafetyinformation.Thisisthesafety-alertsymbol'_'_.
When you see this symbol on the unit and in instructions or manuals,
be alert to the potential for personal injury. Understand these signal
words: DANGER, WARNING, and CAUTION. These words are
used with the safety-alert symbol. DANGER identifies the most se-
rious hazards which will result in severe personal injury or death.
WARNING signifies hazards which could result in personal injury
or death. CAUTION is used to identify unsafe practices which may
result in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in en-
hanced installation, reliability, or operation.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing or servicing system, always turn off main
power to system. There may be more than one disconnect
switch. Turn off accessory heater power switch if applicable.
Step 2--Provide Unit Support
For hurricane tie downs, contact distributor for details and PE
(Professional Engineering) Certificate if required.
ROOF CURB
Install accessory roof curb in accordance with instructions shipped
with curb (See Fig. 5). Install insulation, cant strips, roofing, and
flashing. Ductwork must be attached to curb.
IMPORTANT: The gasketing of the unit to the roof curb is critical
for a water tight seal. Install gasketing material supplied with the
roof curb. Improperly applied gasketing also can result in air leaks
and poor unit performance.
Curb should be level to within 1/4 in. This is necessary for unit drain
to function properly. Refer to accessory roof curb installation
instructions for additional information as required.
SLAB MOUNT
Place the unit on a solid, level concrete pad that is a minimum of 4
in. thick with 2 in. above grade (See Fig. 2). The slab should extend
approximately 2 in. beyond the casing on all 4 sides of the unit. Do
not secure the unit to the slab except when required by local codes.
FIRE, EXPLOSION, ELECTRICAL SHOCK AND
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or unit damage.
A qualified installer or agency must use only
factory-authorized kits or accessories when modifying this
product.
INTRODUCTION
The PY3P unit (see Fig. 1) is a fully self-contained, combination
Category I gas heating/electric cooling unit designed for outdoor
installation (See Fig. 3 and 4 for unit dimensions). All unit sizes
have return and discharge openings for both horizontal and
downflow configurations, and are factory shipped with all
downflow duct openings covered. Units may be installed either on
a rooftop, a cement slab, or directly on the ground, if local codes
permit (See Fig. 5 for roof curb dimensions).
Models with an N in the thirteenth position of the model number are
dedicated Low NOx units designed for California installations.
These models meet the California maximum oxides of nitrogen
(NOx) emissions requirements of 40 nanograms/joule or less as
shipped from the factory and must be installed in California Air
Quality Management Districts or any other regions in North
America where a Low NOx rule exists.
NOTE: Low NOx requirements apply only to natural gas
installations.
RECEIVING AND INSTALLATION
Step 1--Check Equipment
IDENTIFY UNIT
The unit model number and serial number are stamped on the unit
information plate. Check this information against shipping papers.
INSPECT SHIPMENT
Inspect for shipping damage while unit is still on shipping pallet. If
unit appears to be damaged or is torn loose from its anchorage, have
it examined by transportation inspectors before removal. Forward
claim papers directly to transportation company. Manufacturer is
not responsible for any damage incurred in transit. Check all items
against shipping list. Immediately notify the nearest equipment
distribution office if any item is missing. To prevent loss or damage,
leave all parts in original packages until installation.

GROUND MOUNT
The unit may be installed either on a slab or placed directly on the
ground, if local codes permit. Place the unit on level ground
prepared with gravel for condensate discharge.
Step 3--Field Fabricate Ductwork
Secure all ducts to roof curb and building structure on vertical
discharge units. Do not connect ductwork to unit. For horizontal
applications, unit is provided with flanges on the horizontal
openings. All ductwork should be secured to the flanges. Insulate
and weatherproof all external ductwork, joints, and roof openings
with counter flashing and mastic in accordance with applicable
codes.
Ducts passing through an unconditioned space must be insulated
and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return should be
ducted through the roof deck to comply with applicable fire codes.
A minimum clearance is not required around duGwork. Cabinet

Step 4--Provide Clearances
The required minimum operating and service clearances are shown
in Fig. 3 and 4. Adequate combustion, ventilation and condenser air
must be provided in accordance with section 5.3. Air for
Combustion and Ventilation, of the National Fuel Gas Code ANSI
(American National Standards Institute) Z223.1 or applicable
provisions of local building code. In Canada, follow sections 7.2,
7.3, or 7.4 or Can/CGA. (Canadian Gas Association) B149
Installation Codes or applicable provisions of local building code.
IMPORTANT: Do not restrict outdoor airflow. An air restriction at
either the outdoor-air inlet or the fan discharge may be detrimental
to compressor life.
The condenser fan pulls air through the condenser coil and
discharges it through the top grille. Be sure that the fan discharge
does not recirculate to the condenser coil. Do not locate the unit in
either a corner or under an overhead obstruction. The minimum
clearance under a partial overhang (such as a normal house
overhang) is 48-in. above the unit top. The maximum horizontal
extension of a partial overhang must not exceed 48-in.
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting or other combustible materials. Slab-mounted units
should be at least 4 in. above the highest expected water and runoff
levels. Do not use unit if it has been under water.
Step 5--Rig and Place Unit
Rigging and handling of this equipment can be hazardous for many
reasons due to the installation location (roofs, elevated structures,
etc.).
Only trained, qualified crane operators and ground support staff
should handle and install this equipment.
When working with this equipment, observe precautions in the
literature, on tags, stickers, and labels attached to the equipment, and
any other safety precautions that might apply.
Training for operators of the lifting equipment should include, but
not be limited to. the following:
1. Application of the lifter to the load, and adjustment of the
lifts to adapt to various sizes or kinds of loads.
2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting
kit, such as balance, temperature, etc.
Follow all applicable safety codes. Wear safety shoes and work
gloves.
INSPECTION
The lifting/rigging bracket is engineered and designed to be
installed on@ on Small Packaged Products. This bracket is to be
used to rig/lift a Small Packaged Product onto roofs or other
elevated structures.
Prior to initial use, and at monthly intervals, all rigging brackets and
straps should be visually inspected for any damage, evidence of
wear. structural deformation, or cracks. Particular attention should
be paid to excessive wear at hoist hooking points and load support
areas. Brackets or straps showing any kind of wear in these areas
nmst not be used and should be discarded.
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Rigging brackets for one unit use only. When removing a
unit at the end of its useful life. use a new set of brackets.
USE OF RIGGING BRACKET
Field Installation of Ri_in_ Bracket (if not already installed)
1. Remove unit from shipping carton. Leave top shipping skid
on the unit for use as a spreader bar to prevent the rigging
straps from damaging the unit. If the skid is not available, use
a spreader bar of sufficient length to protect the unit from
damage.
2. Remove 4 screws in unit corner posts.
3. Attach each of the 4 metal rigging brackets under the panel
rain lip (See Fig. 6). Use the screws removed in step 2 above
to secure the brackets to the unit.
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Rigging bracket MUST be under the rain lip to provide
adequate lifting.
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Do not strip screws when re-securing the unit. If a screw is
stripped, replace the stripped one with a larger diameter screw
(included). When straps are taut, the clevis should be a
minimum of 36 inches above the unit top cover.
Ri_,_in_/Liftin_ of Unit
1. Bend top of brackets down approximately 30 degrees from
the corner posts.
2. Attach straps of equal length to the rigging brackets at
opposite ends of the unit. Be sure straps are rated to hold the
weight of the unit (See Fig. 6).
3. Attach a clevis of sufficient strength in the middle of the
straps. Adjust the clevis location to ensure unit is lifted level
with the ground.
4. After unit is securely in place detach rigging straps. Remove
corner posts screws, and rigging brackets then reinstall
screws.
After the unit is placed on the roof curb or mounting pad, remove
the top crating.
UNIT FALLING HAZARD
Failure to follow this warning could result in personal injury
or death.
Never stand beneath rigged units or lift over people.

Step 6--Connect Condensate Drain
NOTE: When installing condensate drain connection be sure to
comply with local codes and restrictions.
Model PY3P disposes of condensate water through a 3/4 in. NPT
fitting which exits through the base on the evaporator coil access
side. See Fig. 3 & 4 for location.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground
level installations. Install a field-supplied 2-in. condensate trap at
the end of condensate connection to ensure proper drainage. Make
sure that the outlet of the trap is at least 1 in. lower than the drain-pan
condensate connection to prevent the pan from overflowing (See
Fig. 7). Prime the trap with water. When using a gravel apron, make
sure it slopes away from the unit.
Connect a drain tube using a mininmm of 3/4-in. PVC or 3/4-in.
copper pipe (all field-supplied) at the outlet end of the 2-in. trap.
Do not undersize the tube. Pitch the drain tube downward at a slope
of at least l-in. for every 10 ft of horizontal run. Be sure to check
the drain tube for leaks.

Step8--Install Gas Piping
The gas supply pipe enters the unit through the access hole
provided. The gas connection to the unit is made to the 1/2-in. FPT
gas inlet on the gas valve.
Install a gas supply line that runs to the heating section. Refer to
Table 2 and the NFGC for gas pipe sizing. Do not use cast-iron pipe.
It is recommended that a black iron pipe is used. Check the local
utility for recommendations concerning existing lines. Size gas
supply piping for 0.5 in. wc maximum pressure drop. Never use
pipe smaller than the 1/2-in. FPT gas inlet on the unit gas valve.
For natural gas applications, the gas pressure at unit gas connection
must not be less than 4.0 in. wc or greater than 13 in. wc while the
unit is operating. For propane applications, the gas pressure must
not be less than 7.0 in. wc or greater than 13 in. wc at the unit
connection.
A 1/8-in. NPT plugged tapping, accessible for test gauge
connection, must be installed immediately upstream of the gas
supply connection to the gas valve.
When installing the gas supply line, observe local codes pertaining
to gas pipe installations. Refer to the NFGC ANSI Z223.1-2005
NFPA latest edition (in Canada, CAN/CGA B149.1).

3. When lever handle type manual equipment shutoff valves
are used. they shall be T-handle valves.
4. The use of copper tubing for gas piping is NOT approved by
the state of Massachusetts.
In the absence of local building codes, adhere to the following
pertinent recommendations:
1. Avoid low spots in long runs of pipe. Grade all pipe 1/4 in.
for every 15 ft of length to prevent traps. Grade all horizontal
runs downward to risers. Use risers to connect to heating
section and to meter.
2. Protect all segments of piping system against physical and
thermal damage. Support all piping with appropriate straps,
hangers, etc. Use a minimum of one hanger every 6 ft. For
pipe sizes larger than 1/2 in., follow recommendations of
national codes.
3. Apply joint compound (pipe dope) sparingly and only to
male threads of joint when making pipe connections. Use
only pipe dope that is resistant to action of liquefied
petroleum gases as specified by local and/or national codes.
Never use Teflon tape.
4. Install sediment trap in riser leading to heating section (See
Fig. 8). This drip leg functions as a trap for dirt and
condensate.
5. Install an accessible, external, manual main shutoff valve in
gas supply pipe within 6 ft of heating section.
6. Install ground-joint union close to heating section between
unit manual shutoff and external manual main shut-off
valve.
7. Pressure test all gas piping in accordance with local and

UNIT DAMAGE HAZARD
Failure to follow this caution may result in reduced unit and/or
component life.
Do Not redrill an orifice. Improper drilling (burrs,
out-of-round holes, etc.) can cause excessive burner noise
and misdirection of burner flame. If orifice hole appears
damaged or it is suspected to have been redrilled, check orifice
hole with a numbered drill bit of correct size.
ADJUST GAS INPUT
The gas input to the unit is determined by measuring the gas flow
at the meter or by measuring the manifold pressure. Measuring the
gas flow at the meter is recommended for natural gas units. The
manifold pressure must be measured to determine the input of
propane gas units.
Measure Gas Flow (Natural Gas Units)
Minor adjustment to the gas flow can be made by changing the
manifold pressure. The manifold pressure must be maintained
between 3.4 and 3.6 in. wc.
If larger adjustments are required, change main burner orifices
following the recommendations of national and local codes.
NOTE: All other appliances that use the same meter must be turned
off when gas flow is measured at the meter.

Proceed as follows:
1. Turn off gas supply to unit.
2. Remove pipe plug on manifold (See Fig. 13) and connect
manometer. Turn on gas supply to unit.
3. Record number of seconds for gas meter test dial to make one
revolution.
4. Divide number of seconds in Step 3 into 3600 (number of
seconds in one hr).
5. Multiply result of Step 4 by the number of cubic feet (cu ft)
shown for one revolution of test dial to obtain cubic feet (cu
ft) of gas flow per hour.
6. Multiply result of Step 5 by Btu heating value of gas to
obtain total measured input in Btuh. Compare this value with
heating input shown in Table 3 (Consult the local gas
supplier if the heating value of gas is not known).
EXAMPLE: Assume that the size of test dial is 1 cu ft, one
revolution takes 32 sec., and the heating value of the gas is 1050
Btu/ft3. Proceed as follows:
1. 32 sec. to complete one revolution.
2. 3600 + 32 = 112.5.
3. 112.5 x 1 =112.5 ft3 of gas flow/hr.
4. 112.5 x 1050 = 118,125 Btuh input.
If the desired gas input is 115.000 Btuh, only a minor change in the
manifold pressure is required.
Observe manifold pressure and proceed as follows to adjust gas
input:
1. Remove cover screw over regulator adjustment screw on gas
valve.
2. Turn regulator adjustment screw clockwise to increase gas
input, or turn regulator adjustment screw counterclockwise
to decrease input. Manifold pressure must be between 3.4
and 3.6 in. wc. Unsafe operation of the unit may result if
manifold pressure is outside this range. Personal injury or
unit damage may result.
FIRE AND UNIT DAMAGE HAZARD
Failure to follow this warning could result in personal injury
or death and/or property damage.
Unsafe operation of the unit may result if manifold pressure is
outside this range.
3. Replace cover screw cap on gas valve.
4. Turn off gas supply to unit. Remove manometer from
pressure tap and replace pipe plug on gas valve. Turn on gas
to unit and check for leaks.
Measure Manifold Pressure (Propane Units)
The main burner orifices on a propane gas unit are sized for the unit
rated input when the manifold pressure reading matches the level
specified in Table 3.
Proceed as follows to adjust gas input on a propane gas unit:
1. Turn off gas to unit.
2. Remove pipe plug on manifold and connect manometer (See
Fig. 13).
3. Turn on gas to unit.
4. Remove cover screw over regulator adjustment screw on gas
valve.
5. Adjust regulator adjustment screw to the correct manifold
pressure, as specified in Table 3. Turn adjusting screw
clockwise to increase manifold pressure, or turn adjusting
screw counterclockwise to decrease manifold pressure.
6. Replace cover screw.
7. Turn off gas to unit. Remove manometer from pressure tap.
Replace pipe plug on gas valve, then turn on gas to unit.
Check for leaks.
CHECK BURNER FLAME
With burner access panel removed, observe the unit heating
operation. Watch the burner flames to see if they are light blue and
soft in appearance, and that the flames are approximately the same
for each burner. Propane will have blue flame (See Fig. 14). Refer
to the Maintenance section for information on burner removal.
AIRFLOW AND TEMPERATURE RISE
The heating section for each size unit is designed and approved for
heating operation within the temperature-rise range stamped on the
unit rating plate.
Table 8 shows the approved temperature rise range for each heating
input, and the air delivery cfm at various temperature rises. The
heating operation airflow must produce a temperature rise that falls
within the approved range.
Refer to Indoor Airflow and Airflow Adjustments section to adjust
heating airflow when required.
HEATING SEQUENCE OF OPERATION
(See Fig. 15-17 and unit wiring label.)
On a call for heating, terminal W of the thermostat is energized.
starting the induced- draft motor. When the hall-effect sensor on the
induced-draft motor senses that it has reached the required speed.
the burner sequence begins. This function is performed by the
integrated gas control (IGC). The indoor (evaporator)-fan motor is
energized 45 sec. after flame is established. When the thermostat is
satisfied and W is de-energized, the burners stop firing and the
indoor (evaporator) fan motor shuts off after a 45-sec. time-off
delay.
An LED (light-emitting diode) indicator is provided on the control
board to monitor operation. The control board is located by
removing the burner access panel. During normal operation, the
LED is continuously on (See Table 4 for error codes).

LIMIT SWITCHES
Normally closed limit switch (LS) completes the control circuit.
Should the leaving-air temperature rise above the maximum
allowable temperature, the limit switch opens and the control circuit
"breaks." Any interruption in the control circuit instantly closes the
gas valve and stops gas flow to the burners and pilot. The blower
motor continues to run until LS resets.
When the air temperature at the limit switch drops to the
low-temperature setting of the limit switch, the switch closes and
completes the control circuit. The direct-spark ignition system
cycles and the unit returns to normal heating operation.
ROLLOUT SWITCH
The function of the rollout switch is to close the main gas valve in
the event of flame rollout. The switch is located above the main
burners. When the temperature at the rollout switch reaches the
maximum allowable temperature, the control circuit trips, closing
the gas valve and stopping gas flow to the burners. The indoor
(evaporator) fan motor (IFM) and induced draft motor continue to
run until switch is reset. The IGC LED will display FAULT CODE
7.
Step 3---START-UP COOLING AND MAKE ADJUST-
MENTS
Complete the required procedures given in the Pre-Start-Up
section before starting the unit. Do not jumper any safety devices
when operating the unit. Do not operate the compressor when the
outdoor temperature is below 40°F (unless accessory low-ambient
kit is installed). Do not rapid-cycle the compressor. Allow 5
minutes between on cycles to prevent compressor damage.
CHECKING COOLING CONTROL OPERATION
Start and check the unit for proper cooling control operation as
follows:
1. Place room thermostat SYSTEM switch in OFF position.
Observe that blower motor starts when FAN switch is placed
in ON position and shuts down when FAN switch is placed
in AUTO position.
2. Place SYSTEM switch in COOL position and FAN switch
in AUTO position. Set cooling control below room
temperature. Observe that compressor, condenser fan, and
evaporator blower motors start. Observe that cooling cycle
shuts down when control setting is satisfied. The evaporator
fan will continue to run for 30 sec.
3. When using an auto-changeover room thermostat, place
both SYSTEM and FAN switches in AUTO positions.
Observe that unit operates in Heating mode when
temperature control is set to call for heating (above room
temperature) and operates in Cooling mode when
temperature control is set to call for cooling (below room
temperature).
IMPORTANT: Three-phase, scroll compressors are direction
oriented. Unit must be checked to ensure proper compressor
3-phase power lead orientation. If not corrected within 5 minutes,
the internal protector will shut off the compressor. The 3-phase
power leads to the unit must be reversed to correct rotation. When
turning backwards, the difference between compressor suction and
discharge pressures may be dramatically lower than normal.
CHECKING AND ADJUSTING REFRIGERANT CHARGE
The refrigerant system is fully charged with R-22 refrigerant and
is tested and factory sealed. Allow system to operate a minimum of
15 minutes before checking or adjusting charge.
NOTE:Adjustment of the refrigerant charge is not required unless
the unit is suspected of not having the proper R-22 charge.
The charging label and the tables shown refer to system
temperatures and pressures in cooling mode only. A refrigerant
charging label is attached to the outside of the service access door.
The chart includes the required suction line temperature at given
suction line pressures and outdoor ambient temperatures.
An accurate superheat, thermocouple- or thermistor-type
thermometer, and a gauge manifold are required when using the
superheat charging method for evaluating the unit charge. Do not
use mercury or small dial-type thermometers because they are not
adequate for this type of measurement.
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit damage.
When evaluating the refrigerant charge, an indicated
adjustment to the specified factory charge must always be very
minimal. If a substantial adjustment is indicated, an abnormal
condition exists somewhere in the cooling system, such as
insufficient airflow across either coil or both coils.
Proceed as follows:
1. Remove caps from low- and high-pressure service fittings.
2. Using hoses with valve core depressors, attach low- and
high-pressure gauge hoses to low- and high-pressure
service fittings, respectively.
3. Start unit in Cooling Mode and let unit run until system
pressures stabilize.
4. Measure and record the following:
a. Outdoor ambient-air temperature (°F (°C) db).
b. Liquid line temperature (°F (°C)).
c. Discharge (high-side) pressure (psig).
5. Using "Cooling Charging Charts," compare outdoor-air
temperature(°F (°C) db) with the discharge line pressure
(psig) to determine desired system operating liquid line
temperature (See Table 6).
6. Compare actual liquid line temperature with desired liquid
line temperature. Using a tolerance of -+2°K add refrigerant
if actual temperature is more than 2°F higher than proper
liquid line temperature, or remove refrigerant if actual
temperature is more than 2°F lower than required liquid line
temperature.
NOTE: If the problem causing the inaccurate readings is a
refrigerant leak, refer to the Check for Refrigerant Leaks section.

To change the speed of the indoor fan motor (IFM), remove the fan
motor speed leg lead from the blower relay (BR). This wire is
attached to terminal blower motor (BM) of the integrated gas control
(IGC) board for single-phase units. To change the speed, remove
and replace with lead for desired blower motor speed. Insulate the
removed lead to avoid contact with chassis parts.
COOLING SEQUENCE OF OPERATION
With the room thermostat SYSTEM switch in the COOL position
and the FAN switch in the AUTO position, the cooling sequence of
operation is as follows:
1. When the room temperature rises to a point that is slightly
above the cooling control setting of the thermostat, the
thermostat completes the circuit between thermostat
terminal R to terminals Y and G.
2. The normally open contacts of energized contacmr ((7) close
and complete the circuit through compressor motor (COMP)
to condenser (outdoor) fan motor (OFM). Both motors start
instantly.
3. The set of normally open contacts of energized relay BM
close and complete the circuit through evaporator blower
(indoor) fan motor (IFM).
NOTE: Once the compressor has started and then stopped, it should
not be started again until 5 minutes have elapsed. The cooling cycle
remains on until the room temperature drops to a point that is
slightly below the cooling control setting of the room thermostat. At
this point, the thermostat breaks the circuit between thermostat
terminal R to terminals Y and G. These open circuits deenergize
contactor coil C. The condenser and compressor motors stop. After
a 30-sec. delay, the blower motor stops. The unit is in a standby
condition, waiting for the next call for cooling from the room
thermostat.

Unit undersized for application
Restricted airflow
Limit switch cycles main burners
Incomplete combustion results in: Aldehyde odors,
carbon monoxide, sooting flame, floating flame
REMEDY
Drain, Install drip leg.
Check power supply fuses, wiring or circuit
breaker,
Check transformer.
NOTE: Some transformers have internal over-
current protection that requires a cool-down peg
od to reset.
Check all widng and wire nut connections
Check flame ignition and sense electrode posi-
tioning.
Adiust as necessary,
1. Check gas line for air, Purge as necessary.
NOTE: After purging gas line of air, wait at least 5
minutes for any gas to dissipate before attempt-
ing to light unit.
2. Check gas valve.
Clean or replace filter as necessary
Check gas pressure at manifold match with that
on unit namepmate
Replace with proper unit or add additional unit
Clean or replace filter, Remove any restriction,
Check rotation of blower, temperature rise of unit.
Adiust as necessary,
1. Tighten all screws around burner compartment
2. Cracked heat exchanger. Replace,
3. Unit over-fired. Reduce input (change orifices
or ad}ust gas line or manifold pressure),
4. Check burner alignment,
5. Inspect heat exchanger for bbckage. Clean
as necessary,

SYMPTOM CAUSE REMEDY
Check 5-amp fuse son IGC*, power to unit, 24-v circuit
Hardware failure breaker, and transformer. Units without a24-v circuit
(LED OFF) breaker have an internal overload inthe 24-v transformer.
If the overload trips, allow 10 minutes for automatic reset.
Fan ON/OFF delay modified Ensure unit is fired on rate; ensure temperature rise is cor-
rect, Ensure unit's external static pressure is within applica-
(LED/FLASH) tion guidelines,
Check the operation of the indoor (evaporator) fan motor,
Limit switch faults Ensure that the supply-air temperature rise is in accor-
(LED 2 flashes) dance with the range on the unit nameplate, Clean or re-
place filters,

4 consecutive limit switch faults Check the operation of the indoor (evaporator) fan motor
(LED 4 flashes) and that supply-air temperature rise agrees with range on
unit nameplate information,
Check ignitor and flame sensor electrode spacing, gaps,
Ignition lockout etc, Ensure that fame sense and ignition wires are propedy
(LED 5 flashes) terminated. Verify that unit is obtaining proper amount of
gas.
Check for proper voltage. If motor is operating, check the
