Air Filter(s) — Air filter(s) should be checked at least  
every 3 or 4 weeks and changed or cleaned when necessary.  
Table 1 indicates the correct filter size for your unit. See Fig. 4  
for filter access door location.  
To replace or inspect filters:  
1. Lift up and remove filter access panel.  
2. While holding filter, tilt upper filter rack.  
3. Remove filters by pulling up and out toward you from  
the track.  
4. Inspect or replace filters.  
5. Return filters to filter track. Note direction of airflow ar-  
rows on filter frame.  
6. Replace filter access panel.  
Heat Exchanger — To ensure dependable and efficient  
heating operation, the heat exchanger should be checked by  
a qualified maintenance person before each heating season,  
and cleaned when necessary. This checkout should not be  
attempted by anyone not having the required expertise and  
equipment to do the job properly. Checking and/or cleaning  
the heat exchanger involves removing the gas controls as-  
sembly and the flue collector box cover and, when com-  
pleted, reinstalling the gas controls assembly for proper op-  
eration. Also, the flue collector box cover must be replaced  
correctly so that a proper seal is maintained. Contact your  
dealer for the required periodic maintenance.  
Fans, Belts and Fan Motor — Periodically check the  
condition of the fan wheels and housings, belt tension and  
fan motor shaft bearings. No lubrication of condenser or evapo-  
rator fan bearings or motors is required or recommended.  
If you have difficulty in locating your air filter, or if you  
have questions concerning proper filter maintenance, con-  
tact your dealer for instructions. When replacing your unit  
filters, always use the same size and type of filter that was  
originally supplied by the installer.  
Evaporator and Condenser Coils — Cleaning of  
the coils should be done by qualified service personnel. Contact  
your dealer for the required annual maintenance.  
Units with outdoor air capability have a cleanable filter  
for the outdoor air. This filter should be checked annually  
and cleaned as necessary with steam or hot water and a mild  
detergent. Do not use throwaway filters in place of cleanable  
filters.  
Condensate Drain — The drain pan and condensate  
drain line should be checked and cleaned at the same time  
the cooling coils are checked by your dealer.  
Compressor — All compressors are factory supplied with  
a normal charge of the correct type refrigeration-grade oil in  
them and should not require additional oil.  
Condenser Fan  
Never operate your unit without filters in place. Failure  
to heed this warning may result in damage to the blower  
motor and/or compressor. An accumulation of dust and  
lint on internal parts of your unit can cause loss of ef-  
ficiency and, in some cases, fire.  
Do not poke sticks, screwdrivers, or any other  
object into revolving fan blades. Severe bodily injury  
may result.  
The fan must be kept free of all obstructions to ensure  
proper cooling. Contact your dealer for any required service.  
Table 1 — Indoor-Air Filter Data  
Electrical Controls and Wiring — Electrical con-  
trols are difficult to check without proper instrumentation;  
therefore, if there are any discrepancies in the operating cycle,  
contact your dealer and request service.

Refrigerant Circuit — The refrigerant circuit is diffi-  
cult to check for leaks without the proper equipment; there-  
fore, if inadequate cooling is suspected, contact your local  
dealer for service.  
NOTE: Replacement filters should be UL (Underwriters’ Laborato-  
ries) certified or equivalent.

Combustion Area and Vent System — The com-  
bustion area and vent system should be visually inspected  
before each heating season. The normal accumulation of dirt,  
soot, rust, and scale can result in loss of efficiency and im-  
proper performance if allowed to build up.  
Unit Panels — After performing any maintenance or serv-  
ice on the unit, be sure all panels are securely fastened in  
place to prevent rain from entering unit cabinet and to pre-  
vent disruption of the correct unit airflow pattern.  
If your unit makes an unusual or especially loud noises  
during heating, shut down the heating section and call  
your dealer.  
REGULAR DEALER MAINTENANCE  
In addition to the type of routine maintenance you might  
be willing to perform, your unit should be inspected regu-  
larly by a properly trained service technician. An inspection  
(preferably each year, but at least every other year) should  
include the following:  
See Fig. 1A, 1B and 5 and proceed as follows to inspect  
the combustion area and power-venting system of your unit.  
1. Turn off gas supply to your unit.  
2. Turn off electrical power to your unit.  
3. Remove burner access panel.  
4. Using a flashlight, carefully inspect the burner areas for

dirt, soot, or scale.  
2. Inspection of all combustion- and ventilation-air pas-  
sages and openings.  
If dirt, soot, rust, or scale accumulations are found,  
call your dealer and do not operate your heating sec-  
tion.  
3. Close inspection of all gas pipes leading to and inside  
your unit.  
4. Inspection, and if required, cleaning of the condenser  
and evaporator coils.  
5. When you have completed your inspection, follow the  
start-up procedures in this manual to restore your unit to  
operation.  
5. Inspection, and if required, cleaning of the condensate  
drain pan and trap.  
6. Observe unit heating operation.  
6. Inspection and cleaning of blower wheel housing and  
motor.  
Components in heat section may be hot after unit  
has been started up. When observing flame, be care-  
ful not to get to close to or touch heating compo-  
nents. Serious personal injury may result.  
7. Inspection of all supply- and return-air ducts for leaks,  
obstructions, and insulation integrity. Any problems found  
should be resolved at the time of inspection.  
8. Inspection of the unit base for cracks, gaps, etc., which  
may cause a hazardous condition.  
Watch the burner flame to see if it is bright blue. If you  
observe a suspected malfunction or that the burner flame  
is not bright blue, call your dealer.  
9. Inspection of the unit casing for signs of deterioration.  
7. Replace burner access panel.  
10. Inspection of all electrical wiring and components to en-  
sure proper connection.  
11. Inspection for leaks in the refrigerant circuit. Pressure-  
check to determine appropriate refrigerant charge.  
12. Inspection and cleaning of fan wheels and housings, belt  
tension, and fan motor and shaft bearings.  
13. Operational check of the unit to determine working con-  
ditions. Repair or adjustment should be made at the time  
of inspection.  
Your servicing dealer may offer an economical service con-  
tract that covers seasonal inspections. Ask for further de-  
tails.
