to the blower motor and/or compressor. An accumulation
of dust and lint on internal parts of your unit can cause
loss of efficiency and, in some cases, fire.
B.
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 properly do the job. Checking
and/or cleaning the heat exchanger involves removing the gas
controls assembly and the flue collector box cover and, when
completed, reinstalling the gas controls assembly for proper
operation. 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.
Air Filters
Air filter(s) should be checked at least every 3 or 4 weeks and
changed or cleaned whenever it becomes dirty. Dirty filters
produce excessive stress on the blower motor and can cause the
motor to overheat and shut down. Table 1 indicates the correct
filter size for your unit. Refer to Fig. 3 to access the filter(s).
To replace or inspect filter(s) (or accessory filter rack when
supplied):
C.
Fans and Fan Motor
Periodically check the condition of fan wheels and housings and
fan-motor shaft bearings. No lubrication of condenser- or
evaporator-fan bearings or motors is required or recommended.
D.
1. Remove the filter access panel using a 5/16-in. nut driver.
Evaporator and Condenser Coils
Cleaning of the coils should only be done by qualified service
personnel. Contact your dealer for the required annual maintenance.
2. Remove the filter(s) by pulling the filter(s) out of the unit.
If the filter(s) is dirty, clean or replace with new one.
When installing the new filter(s), note the direction of the airflow
arrows on the filter frame.
E.
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.
If you have difficulty in locating your air filter(s), or if you have
questions concerning proper filter maintenance, contact your
dealer for instructions. When replacing filters, always use the same
size and type of filter that was supplied originally by the installer.
F.
Compressor
All compressors are factory-shipped with a normal charge of the
correct type refrigeration grade oil in them and should rarely
require additional oil.

careful not to get close to or touch heating components or
personal injury may result.
BEFORE YOU CALL FOR SERVICE,
CHECK FOR SEVERAL EASILY-SOLVED PROBLEMS
If insufficient heating or cooling is suspected:
( ) Check for sufficient airflow. Check the air filter for dirt. Check
for blocked return-air or supply-air grilles. Be sure they are open
and unobstructed. If these checks do not reveal the cause, call your
servicing dealer.
If your unit is not operating at all, check the following list for easy
solutions:
( ) Check to be sure that your thermostat temperature selector is set
above the indoor temperature during the heating season, or below
the indoor temperature during the cooling season. Be sure the
system switch is in the proper HEAT or COOL position and not in
the OFF position.
( ) Is the electrical supply switch ON? Are any fuses blown, or has
the circuit breaker tripped?
( ) During the heating season, check the external manual shutoff
valve. Is this lever parallel with the pipe, indicating that the valve
is open? Or is the lever at a right angle, indicating that the valve
is closed? If closed, has the gas been shut off for safety reasons?
Otherwise, you may open the valve and follow the start-up
procedures listed in this manual.
NOTE: Before proceeding with the next check, turn OFF the gas
supply, then the electrical power supply to the unit. Remove the
control access door.
Watch the burner flame to see if it is bright blue. If you observe a
suspected malfunction or if the burner flames are not bright blue,
call your dealer.
6. Replace burner access panel.
WARNING: System under pressure. Relieve pressure
and recover all refrigerant before system repair or final
unit disposal to avoid serious injury or death. Use all
service ports and open all flow-control devices, including
solenoid valves.
K.

all panels are fastened securely in place to prevent rain from
entering unit cabinet and to prevent disruption of the correct unit
airflow pattern.
REGULAR DEALER MAINTENANCE
In addition to the type of routine maintenance you might be willing
to perform, your unit should be inspected regularly by a properly
trained service technician. An inspection (preferably each year, but
at least every other year) should include the following:
( ) During the heating season, check the control dial on the internal
gas valve. Is it in the ON position? If it is not, be sure it was not
turned off for the propose of safety. If no safety hazards exist,
follow the start-up procedures in this manual.
1. Inspection of all flue product passages—including the
burners, heat exchangers, and flue collector box.
2. Inspection of all combustion- and ventilation-air passages
and openings.
( ) If your unit still fails to operate, call your servicing dealer for
troubleshooting and repairs. Specify the model and serial numbers
of your unit. (Record them in this manual in the space provided.)
If the dealer knows exactly which unit you have, he may be able
