condenser coil, evaporator coil with thermostatic expansion valve), a circulation air blow-
er, a condenser fan, a heat exchanger assembly, gas burner and control assembly,
combustion air motor and fan, and all necessary internal electrical wiring. The cooling
system of these units is factory-evacuated, charged with R-410A refrigerant and perfor-
mance tested. Refrigerant amount is indicated on rating plate.
C. R410A REFRIGERANT
All units are factory charged with R-410A refrigerant.
1. Specification of R-410A:
Application: R-410A is not a drop-in replacement for R-22; equipment designs must
accommodate its higher pressures. It cannot be retrofitted into R-22 units.
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than R-
22. Recovery and recycle equipment, pumps, hoses and the like need to have design
pressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psig
high-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have a
service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service
pressure rating. DOT 4BA400 or DOT BW400.
Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air can
become combustible. R-410A and air should never be mixed in tanks or supply
lines, or be allowed to accumulate in storage tanks. Leak checking should never
be done with a mixture of R-410A and air. Leak checking can be performed safely
with nitrogen or a mixture of R-410A and nitrogen.

2. Quick Reference Guide For R-410A
• R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R-
22. Ensure that servicing equipment is designed to operate with R-410A.
• R-410A refrigerant cylinders are pink.
• R-410A, as with other HFC’s is only compatible with POE oils.
• Vacuum pumps will not remove moisture from POE oil.
• R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R-
410A refrigerant cylinders had a dip tube. These cylinders should be kept upright for
equipment charging. Post March 1999 cylinders do not have a dip tube and should
be inverted to ensure liquid charging of the equipment.
•Do not install a suction line filter drier in the liquid line.
• A liquid line filter drier is standard on every unit.
• Desiccant (drying agent) must be compatible for POE oils and R-410A
3. Evaporator Coil / TXV
The thermostatic expansion valve is specifically designed to operate with R-410A. DO
NOT use an R-22 TXV. The existing evaporator must be replaced with the factory
specified TXV evaporator specifically designed for R-410A.
4. Tools Required For Installing & Servicing R-410A Models

VI. INSTALLATION
A. GENERAL
1. PRE-INSTALLATION CHECK-POINTS — Before attempting any installation, care-
fully consider the following points:
Structural strength of supporting members
(Rooftop Installation)
Clearances and provision for servicing
Power supply and wiring
Gas supply and piping
Air duct connections and sizing
Drain facilities and connections
Location for minimum noise and vibration
2. LOCATION CONSIDERATIONS (CORROSIVE ENVIRONMENT)
The metal parts of this unit may be subject to rust or deterioration if exposed to a
corrosive environment. This oxidation could shorten the equipment’s useful life.
Corrosive elements include, but are not limited to, salt spray, fog or mist in seacoast
areas, sulphur or chlorine from lawn watering systems, and various chemical conta-
minants from industries such as paper mills and petroleum refineries.
If the unit is to be installed in an area where contaminants are likely to be a
problem, give special attention to the equipment location and exposure.
1. Avoid having lawn sprinkler heads spray directly on the unit cabinet.
2. In coastal areas locate the unit on the side of the building away from the water-
front.
3. Shielding by a fence or shrubs may give some protection.
1. Frequent washing of the cabinet, fan blade and coil with fresh water will remove
most of the salt or other contaminants that build up on the unit.
2. Regular cleaning and waxing of the cabinet with a good automobile polish will pro-
vide some protection.
3. Use a good liquid cleaner several times a year to remove matter that will not wash
off with water.
Several different types of protective coatings are offered in some areas. These coatings
may provide some benefit, but the effectiveness of such coating materials cannot be ver-
ified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to
contaminants.
B. OUTSIDE INSTALLATION
(Typical outdoor slab installation is shown in Figure 2.)
1. Select a location where external water drainage cannot collect around unit.
!WARNING
DISCONNECT ALL POWER TO UNIT BEFORE STARTING MAINTENANCE.
FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK RESULTING IN PER-
SONAL INJURY OR DEATH.
!WARNING
THESE UNITS ARE DESIGNED CERTIFIED FOR OUTDOOR INSTALLATION
ONLY. INSTALLATION INSIDE ANY PART OF A STRUCTURE CAN RESULT IN
INADEQUATE UNIT PERFORMANCE AS WELL AS PROPERTY DAMAGE.
INSTALLATION INSIDE CAN ALSO CAUSE RECIRCULATION OF FLUE PROD-
UCTS INTO THE CONDITIONED SPACE RESULTING IN PERSONAL INJURY
OR DEATH.

2. Provide a slab sufficiently high enough above grade to prevent surface water from
entering the unit. Where snowfall is anticipated, mount the unit above the anticipat-
ed maximum snow depth for your area. Do not locate unit in an area where exces-
sive snow drifting may block combustion air inlet.
3. Pitch the slab approximately 1⁄2” so that the unit will be pitched toward the drain. See
Figure 3.
4. The location of the unit should be such as to provide proper access for inspection
and servicing as shown in Figure 9.
5. Locate unit where operating sounds will not disturb owner or neighbors. The slab
should be isolated from the foundation wall.

Place the unit as close to the conditioned space as possible allowing clearances as indi-
cated. Run ducts as directly as possible to supply and return outlets. Use of non-flam-
mable weatherproof flexible connectors on both supply and return connections at unit to
reduce noise transmission is recommended.
On ductwork exposed to outside temperature and humidity, use a minimum of 2” of
insulation and a vapor barrier. Distribution system in attic, furred space or crawl space
should be insulated with at least 2” of insulation. 1⁄2” to 1” thick insulation is usually suffi-
cient for ductwork inside the air conditioned space.
Provide balancing dampers for each branch duct in the supply system. Properly support
ductwork from the structure.
IMPORTANT: In the event that the return air ducts must be run through an “unconfined”
space containing other fuel burning equipment, it is imperative that the user/homeowner
must be informed against future changes in construction which might change this to a
“confined space.” Also, caution the user/homeowner against any future installation of
additional equipment (such as power ventilators, clothes dryers, etc., within the existing
unconfined and/or confined space which might create a negative pressure within the
vicinity of other solid, liquid, or gas fueled appliances.
H. RETURN AIR
!WARNING
NEVER ALLOW PRODUCTS OF COMBUSTION OR THE FLUE PRODUCTS TO
ENTER THE RETURN AIR DUCTWORK, OR THE CIRCULATING AIR SUPPLY.
ALL RETURN DUCTWORK MUST BE ADEQUATELY SEALED AND SECURED
TO THE FURNACE WITH SHEET METAL SCREWS, AND JOINTS TAPED. ALL
OTHER DUCT JOINTS MUST BE SECURED WITH APPROVED CONNECTIONS
AND SEALED AIRTIGHT.
FAILURE TO PREVENT PRODUCTS OF COMBUSTION FROM BEING CIRCU-
LATED INTO THE LIVING SPACE CAN CREATE POTENTIALLY HAZARDOUS
CONDITIONS, INCLUDING CAROBON MONOXIDE POISONING THAT COULD
RESULT IN PERSONAL INJURY OR DEATH.

VII.GAS SUPPLY, CONDENSATE DRAIN AND
VII.PIPING
A. GAS CONNECTION
IMPORTANT: Connect this unit only to gas supplied by a commercial utility.
1. Install gas piping in accordance with local codes and regulations of the local utility
company. In the absence of local codes, the installation must conform to the specifi-
cations of the National Fuel Gas Code, ANSI Z223.1 - latest edition.
NOTE: The use of flexible gas connectors is not permitted.
NOTE: The Commonwealth of Massachusetts requires the gas shut-off valve to be
a T-handle gas cock.
2. Connect the gas line to the gas pipe inlet opening provided into the 1/2” inlet valve.
See Figure 2 for typical piping.
3. Size the gas line to the furnace adequate enough to prevent undue pressure drop
and never less than 1/2”.
4. Install a drip leg or sediment trap in the gas supply line as close to the unit as possi-
ble.
5. Install an outside ground joint union to connect the gas supply to the control assem-
bly at the burner tray.
6. Gas valves have been factory installed. Install a manual gas valve where local codes
specify a shut-off valve outside the unit casing. (See Figure 19.)
7. Make sure piping is tight. A pipe compound resistant to the action of liquefied
petroleum gases must be used at all threaded pipe connections.
8. IMPORTANT: Any additions, changes or conversions required for the furnace to sat-
isfactorily meet the application should be made by a qualified installer, service
agency or the gas supplier, using factory-specified or approved parts. In the com-
monwealth of Massachusetts, installation must be performed by a licensed plumber
or gas fitter for appropriate fuel.
IMPORTANT: Disconnect the furnace and its individual shutoff valve from the gas sup-
ply piping during any pressure testing of that system at test pressures in excess of 1/2
psig or isolate the system from the gas supply piping system by closing its individual
manual shutoff valve during any pressure testing of this gas supply system at pressures
equal to or less than 1/2 PSIG.

TO CHECK FOR GAS LEAKS, USE A SOAP AND WATER SOLUTION OR OTHER
APPROVED METHOD. DO NOT USE AN OPEN FLAME.
IMPORTANT: Check the rating plate to make certain the appliance is equipped to burn
the type of gas supplied. Care should be taken after installation of this equipment that
the gas control valve not be subjected to high gas supply line pressure.
In making gas connections, avoid strains as they may cause noise and damage the con-
trols. A backup wrench is required to be used on the valve to avoid damage.
The capacities of gas pipe of different diameters and lengths in cu. ft. per hr. with pres-
sure drop of 0.5 in. and specific gravity of 0.60 (natural gas) are shown in Table 2.
After determining the pipe length, select the pipe size which will provide the minimum
cubic feet per hour required for the gas input rating of the furnace. By formula:
Gas Input of Furnace
(BTU/HR)
Cu. Ft. Per Hr. Required = Heating Value of Gas
(BTU/FT3)
The gas input of the furnace is marked on the furnace rating plate. The heating value of
the gas (BTU/FT3) may be determined by consulting the local natural gas utility or the
L.P. gas supplier.
B. LP CONVERSION
Convert the valve to use liquefied petroleum (LP) gas by replacing the pressure regulator
spring with the conversion kit spring. This LP kit spring allows the regulator to maintain the
proper manifold pressure for LP gas. The correct burner LP orifices are included in the kit.
See Figure 20.
NOTE: Order the correct LP conversion kit from the furnace manufacturer. See
Conversion Kit Index shipped with unit for proper LP kit number. Furnace conver-
sion to LP gas must be performed by a qualified technician.
!WARNING
DO NOT USE AN OPEN FLAME TO CHECK FOR LEAKS. THE USE OF AN OPEN
FLAME CAN RESULT IN FIRE, EXPLOSION, PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.
!WARNING
THIS UNIT IS EQUIPPED AT THE FACTORY FOR USE ON NATURAL GAS ONLY.
CONVERSION TO LP GAS REQUIRES A SPECIAL KIT SUPPLIED BY THE DIS-
TRIBUTOR OR MANUFACTURER. MAILING ADDRESSES ARE LISTED ON THE
FURNACE RATING PLATE, PARTS LIST AND WARRANTY. FAILURE TO USE
THE PROPER CONVERSION KIT CAN CAUSE FIRE, CARBON MONOXIDE POI-
SONING, EXPLOSION, PERSONAL INJURY, PROPERTY DAMAGE OR DEATH.
FIGURE 20
FIGURE 20

C. NOx MODELS
When converting units equipped with NOx inserts to LP gas, the stainless steel mesh
inserts in the entrance of the tubular exchangers are not required to meet SCAQMD NOx
emission levels. Carefully remove these inserts before firing this furnace on LP gas. This
furnace is not designed to operate on LP gas with the NOx inserts in place.
Step by step instructions on removing the NOx inserts and retaining rod are included in the
Conversion Kit Installation Instructions.
D. ADJUSTING OR CHECKING FURNACE INPUT
– Natural Gas Line Pressure 5” - 10.5” W.C.
– LP Gas Line Pressure 11” - 13” W.C.
– Natural Gas Manifold Pressure 3.5” W.C
– LP Gas Manifold Pressure - 10” W.C.
Supply and manifold pressure taps are located on the gas valve body 1/8” N.P.T.
Use a properly calibrated manometer gauge for accurate gas pressure readings.
Only small variations in the gas flow should be made by means of the pressure regulator
adjustment. Furnaces functioning on LP gas must be set by means of the tank or branch
supply regulators. The furnace manifold pressure should be set at 10” W.C. at the gas con-
trol valve.
To adjust the pressure regulator, remove the regulator cap and turn the adjustment screw
clockwise to increase pressure or counterclockwise to decrease pressure. Then replace
the regulator cap securely.
Any necessary major changes in the gas flow rate should be made by changing the size of
the burner orifices. To change orifice spuds, shut off the manual main gas valve and
remove the gas manifold.
For elevations up to 2,000 feet, rating plate input ratings apply. For high altitudes (elevations
over 2,000 ft.), see conversion kit index 92-21519-XX for derating and orifice spud sizes.
Check of input is important to prevent over-firing of the furnace beyond its design-
rated input. NEVER SET INPUT ABOVE THAT SHOWN ON THE RATING PLATE. Use
the following table or formula to determine input rate.
Heating Value of Gas
(BTU/Cu. Ft.) x 3600

Start the furnace and measure the time required to burn one cubic foot of gas. Prior to
checking the furnace input, make certain that all other gas appliances are shut off, with
the exception of pilot burners. Time the meter with only the furnace in operation.
IMPORTANT NOTE FOR ALTITUDES ABOVE 2,000 FEET (610 METERS): The main
burner orifices in your furnace and in these kits are sized for the nameplate input and
intended for installations at elevations up to 2,000 feet in the USA or Canada, or for ele-
vations of 2,000 - 4,500 feet (610 -1,373 meters) in Canada if the unit has been derated
at the factory. For elevations above 2,000 feet (610 meters) IN THE USA ONLY (see
ANSI-Z223.1), the burner orifices must be sized to reduce the input 4% for each 1,000
feet (305 meters) above sea level.
NOTICE: DERATING OF THE HEATING INPUT FOR HIGH ALTITUDE IN THE FIELD
IS UNLAWFUL IN CANADA (REFER TO CAN/CGA 2.17). UNITS INSTALLED IN
ALTITUDES GREATER THAN 2,000 FEET (610 METERS) MUST BE SHIPPED FROM
THE FACTORY OR FROM A FACTORY AUTHORIZED CONVERSION STATION
WITH THE HEATING INPUT DERATED BY 10% SO AS TO OPERATE PROPERLY IN
ALTITUDES FROM 2,000 - 4,500 FEET (610 - 1,373 METERS).
E. CONDENSATE DRAIN
The evaporator coil condensate drain ends with a threaded 3/4” nominal PVC stub. A
trap is built in for proper condensate drainage and to prevent debris from being drawn
into the unit. Do not connect the drain to a closed sewer line. Connection to a vented
sewer line is allowed. It is recommended that a PVC cement not be used so that the
drain line can be easily cleaned in the future.
IMPORTANT: DO NOT INSTALL AN EXTERNAL TRAP. DOING SO CAN CAUSE
IMPROPER DRAINAGE OF THE CONDENSATE AND RESULT IN FLOODING WITH-
IN THE UNIT.

B. HOOK-UP
To wire unit, refer to the following hook-up diagram (see Figure 21).
Refer to Figure 1 for location of wiring entrances.
Wiring to be done in the field between the unit and devices not attached to the unit, or
between separate devices which are field installed and located, shall conform with the
temperature limitation for Type T wire [63°F rise (35°C)] when installed in accordance
with the manufacturer’s instructions.
C. INTERNAL WIRING
IMPORTANT: Some single phase units are equipped with a single pole contactor.
Caution must be exercised when servicing as only one leg of the power supply is broken
with the contactor.
A diagram of the internal wiring of this unit is located under the electrical box cover and
in this manual. If any of the original wire as supplied with the appliance must be
replaced, the wire gauge and insulation must be same as original wiring.
Transformer is factory wired for 230 volts on 208/230 volt models and must be changed
for 208 volt applications. See unit wiring diagram for 208 volt wiring.
D. THERMOSTAT
The room thermostat must be compatible with the spark ignition control on the unit.
Generally, all thermostats that are not of the “current robbing” type are compatible with
the integrated furnace control. Two stage units (5 ton) require use of a thermostat capa-
ble of 2 stages of cooling. (See Section IV.) See chart below for recommendations. The
low voltage wiring should be sized as shown in Table 6.
Install the room thermostat in accordance with the instruction sheet packed in the box
with the thermostat. Never install the thermostat on an outside wall or where it will be
influenced by drafts, concealed hot or cold water pipes or ducts, lighting fixtures, radia-
tion from fireplace, sun rays, lamps, televisions, radios or air streams from registers.

IX. FURNACE SECTION CONTROLS AND
IGNITION SYSTEM
A. NORMAL FURNACE OPERATING SEQUENCE
This unit is equipped with an integrated direct spark ignition control.
1. The thermostat calls for heat.
2. The control board will run a self check to verify that the limit control and manual reset
overtemperature control are closed and that the pressure switch is open. If so, the
induced draft blower (inducer) begins a prepurge cycle.
3. The air proving negative pressure switch closes.
4. 15 seconds after the pressure switch closes, the gas valve opens and the spark is
initiated for a 7 second trial for ignition.
5. Burners ignite and flame sensor proves all burners have lit.
6. The circulating air blower is energized after 30 seconds.
7. The control board enters a normal operation loop in which all safety controls are moni-
tored continuously.
8. Thermostat is satisfied and opens.
9. The gas valve is de-energized and closes, shutting down the burner flame.
10. The control board will de-energize the inducer after a five second post purge.
11. The circulating air blower is de-energized after 90 seconds.
• The integrated control board has a three ignition system.
• After a total of three trials for ignition without sensing main burner flame, the system
goes into a 100% lockout mode.
• After one hour, the ignition control repeats the prepurge and ignition cycles for 3 tries
and then goes into 100% lockout mode again.
• It continues this sequence of cycles and lockout each hour until ignition is successful or
power is interrupted.
• During the lockout mode, neither the spark ignition control or gas valve will be energized
until the system is reset by turning the thermostat to the “OFF” position or interrupting
the electrical power to the unit for 3 seconds or longer.
• The induced draft blower and main burner will shut off when the thermostat is satisfied.
• The circulating air blower will start and run on the heating speed if the thermostat fan
switch is in the “ON” position.
The integrated furnace control is equipped with diagnostic LED. The LED is lit continuously
when there is power to the control, with or without a call for heat. If the LED is not lit, there
is either no power to the control or there is an internal component failure within the control,
and the control should be replaced.

C. BURNERS
Burners for these units have been designed so that field adjustment is not required.
Burners are tray-mounted and accessible for easy cleaning when required.
D. MANUAL RESET OVERTEMPERATURE CONTROL
A manual reset overtemperature control is located on the burner shield. This device sens-
es blockage in the heat exchanger or insufficient combustion air. This shuts off the main
burners if excessive temperatures occur in the burner compartment.
Operation of this control indicates an abnormal condition. Therefore, the unit should be
examined by a qualified installer, service agency, or the gas supplier before being placed
back into operation.
E. PRESSURE SWITCH
This furnace has a pressure switch for sensing a blocked exhaust or a failed induced draft
blower. It is normally open and closes when the induced draft blower starts, indicating air
flow through the combustion chamber.

7. IMPORTANT: Replace all blower doors and compartment cover after servicing the
unit. Do not operate the unit without all panels and doors securely in place.
8. Do not allow snow or other debris to accumulate in the vicinity of the appliance.
B. FURNACE SECTION MAINTENANCE
The unit’s furnace should operate for many years without excessive scale build-up in flue
passageways; however, it is recommended that a qualified installer, service agency, or the
gas supplier annually inspect the flue passageways, the exhaust system and the burners
for continued safe operation, paying particular attention to deterioration from corrosion or
other sources.
If during inspection the flue passageways and exhaust system are determined to require
cleaning, the following procedures should be followed (by a qualified installer, service
agency, or gas supplier):
1. Turn off the electrical power to the unit and set the thermostat to the lowest tem-
perature.
2. Shut off the gas supply to the unit either at the meter or at manual valve in the
supply piping.
3. Remove the furnace controls access panel and the control box cover.
4. Disconnect the gas supply piping from the gas valve.
5. Disconnect the wiring to the induced draft blower motor, gas valve, flame sensor, and
flame roll-out control, and ignitor cable. Mark all wires disconnected for proper
reconnection.
6. Remove the screws (4) connecting the burner tray to the heat exchanger mounting
panel.
7. Remove the burner tray and the manifold assembly from the unit.
8. Remove the screws (4) connecting the induced draft blower to the collector box and
screws (16) connecting the collector box to the heat exchanger mounting panel.
Remove the induced draft blower and the collector box from the unit.
9. Remove the turbulators from inside the heat exchangers by inserting the blade of a
screwdriver under the locking tabs. Pop the tabs out of the expanded grooves of the
heat exchanger. Slide the turbulators out of the heat exchangers.
10. Direct a water hose into the outlet of the heat exchanger top. Flush the inside of each
heat exchanger tube with water. Blow out each tube with air to remove excessive
moisture.
11. Reassemble (steps 1 through 10 in reverse order). Be careful not to strip out the
screw holes used to mount the collector box and inducer blower. Replace induc-
er blower gasket and collector box gasket with factory replacements if dam-
aged.
The manufacturer recommends that a qualified installer, service agency or the gas suppli-
er visually inspect the burner flames for the desired flame appearance at the beginning of
the heating season and approximately midway in heating season.
The manufacturer also recommends that a qualified installer, service agency or the gas
supplier clean the flame sensor with steel wool at the beginning of the heating season.
!WARNING
HOLES IN THE EXHAUST TRANSITION OR HEAT EXCHANGER CAN CAUSE
TOXIC FUMES TO ENTER THE HOME. THE EXHAUST TRANSITION OR HEAT
EXCHANGER MUST BE REPLACED IF THEY HAVE HOLES OR CRACKS IN
THEM. FAILURE TO DO SO CAN CAUSE CARBON MONOXIDE POISONING
RESULTING IN PERSONAL NJURY OR DEATH.
!WARNING
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CON-
TROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPER-
ATION RESULTING IN FIRE, ELECTRICAL SHOCK, PROPERTY DAMAGE, PER-
SONAL INJURY OR DEATH.
28
C. LUBRICATION
IMPORTANT: DO NOT attempt to lubricate the bearings on the blower motor or the
induced draft blower motor. Addition of lubricants can reduce the motor life and void the
warranty.
The blower motor and induced draft blower motor are prelubricated by the manufacturer
and do not require further attention.
A qualified installer, service agency or the gas supplier must periodically clean the
motors to prevent the possibility of overheating due to an accumulation of dust and dirt
on the windings or on the motor exterior. And, as suggested elsewhere in these instruc-
tions, the air filters should be kept clean because dirty filters can restrict air flow and the
motor depends upon sufficient air flowing across and through it to prevent overheating.
D. COOLING SECTION MAINTENANCE
It is recommended that at the beginning of each cooling season a qualified installer or
service agency inspect and clean the cooling section of this unit. The following areas
should be addressed: evaporator coil, condenser coil, condenser fan motor and venturi
area.
To inspect the evaporator coil:
1. Remove the filter access panel and the blower/evaporator coil access panel.
2. Unplug the wires from the circulating air blower and the limit control. Remove the
two screws and slide the blower out of the unit sideways.
3. Shine a flashlight on the evaporator coil (both sides) and inspect for accumulation of
lint, insulation, etc.
4. If coil requires cleaning, follow the steps shown below.
Cleaning Evaporator Coil
1. Remove screws from condenser fan grille assembly and lay grille over on the unit
top panel.
2. Remove the controls access panel and the control box cover.
3. Disconnect the outdoor fan motor wiring from the compressor contactor and capaci-
tor. Remove the strain relief in the bulkhead and pull the fan motor wires through.
Set grille assembly to the side.
4. Remove the screws that secure the unit top to the unit. Remove the top and set the
unit top to the side.
5. The coil should be cleaned when it is dry. If the coil is coated with dirt or lint, vacu-
um it with a soft brush attachment. Be careful not to bend the coil fins.
6. If the coil is coated with oil or grease, clean it with a mild detergent-and-water solu-
tion. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water
pressure. Excessive water pressure can bend the fins and tubing of the coil and lead
to inadequate unit performance. Be careful not to splash water excessively into unit.
7. Go to next section for cleaning the condenser coil.
Cleaning Condenser Coil, Drain Pan, Condensate Drain, Condenser Fan,
Circulation Air Blower and Venturi
1. Remove the screws from the condenser coil protective grille and remove the grille
from the unit. Ensure the filter access panel is still removed to access all of the
screws securing the grille.
2. The coil should be cleaned when it is dry. If the coil is coated with dirt or lint, vacuum
it with a soft brush attachment. Be careful not to bend the coil fins.
!WARNING

3. If the coil is coated with oil or grease, clean it with a mild detergent-and-water solu-
tion. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water
pressure. Excessive water pressure can bend the fins and tubing of the coil and lead
to inadequate unit performance. Be careful not to splash water excessively into unit.
4. Inspect the drain pan and condensate drain at the same time the condenser coil is
checked. Clean the drain pan by flushing with water and removing any matters of
obstructions which may be present.
5. Flush the drain tube with water. If the drain tube is blocked, it can usually be cleared
wth high pressure water.
6. Inspect the circulating air blower wheel and motor for accumulation of lint, dirt or
other obstruction and clean if necessary. Inspect the blower motor mounts and the
blower housing for loose mounts or other damage. Repair or replace if necessary.
Re-assembly
1. Place the condenser coil protective grille back on unit and replace all screws.
2. Place top panel back on unit and replace all screws.
3. Set condenser fan grille assembly on top of the unit with the fan on top and the
motor wires on the venturi side. Run the fan motor wires through the bulkhead and
pull wires through the hole on the bottom of the control box on the left side and into
the control box. Reconnect fan motor wires per the wiring diagram attached to the
back of the control box cover.
4. Replace wire strain relief in bulkhead after the slack is pulled out of the wires on the
fan side. This will assure wires will not be damaged by the fan during unit operation.
