ard procedure.
For your safety, keep the unit area clear and free of combus-
tible materials, gasoline, and other flammable liquids and

MAINTENANCE AND CARE FOR THE
EQUIPMENT OWNER
Before proceeding with those things you might want to main-
tain yourself, please carefully consider the following:
WARNING:
1. TURN OFF GAS SUPPLY AND ELECTRICAL
POWER TOYOUR UNIT BEFORE SERVICINGOR
PERFORMING MAINTENANCE.
2. Do not turn off electrical power to this unit without
first turning off the gas supply.
3. When removing access panels or performing main-
tenance functions inside your unit, be aware of sharp
sheet metal parts and screws. Although special care
is taken to reduce sharp edges to a minimum, be ex-
tremely careful when handling parts or reaching into
the unit.
I. 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. 5 to access the
filter(s).
To replace or inspect filter(s) (or accessory filter rack when
supplied):
1. Remove the filter access panel using a
5
⁄
16
-in. nut driver.
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 air-
flow arrows on the filter frame.
If you have difficulty in locating your air filter(s), or if you
have questions concerning proper filter maintenance, con-
tact your dealer for instructions. When replacing filters, al-
ways use the same size and type of filter that was supplied
originally by the installer.

WARNING:Never operate your unit without filters
in place. Failure to heed this warning may result in dam-
age to the blower motor and/or compressor. An accumu-
lation of dust and lint on internal parts of your unit
can cause loss of efficiency and, in some cases, fire.
II. Heat Exchanger
To ensure dependable and efficientheatingoperation, the heat
exchanger should be checked by a qualified maintenance per-
son 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 remov-
ing 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. Con-
tact your dealer for the required periodic maintenance.
III. Fans and Fan Motor
Periodically check the condition of fan wheels and hous-
ings and fan-motor shaft bearings. No lubrication of
condenser- or evaporator-fan bearings or motors is required
or recommended.
IV. Evaporator and Condenser Coils
Cleaning of the coils should only be done by qualified service
personnel. Contact your dealer for the required annual
maintenance.
