To replace or inspect filters:

1. Lift up and remove filter access panel.

2. While holding filter, tilt upper filter track.

3. Remove filters by pulling up and out toward you from

the track.

4. Inspect or replace filters.

5. Place filters back in the filter tracks. When installing

filters, note the direction of airflow arrows on the fil-

ter frame.

6. Reinstall filter access panel.

If you have difficulty locating your air filter or if you have

questions concerning proper filter maintenance, contact your

dealer for additional instructions. When replacing your

unit’s filters, always use the same size and type of filter that

was originally supplied by the installer.

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 de-

tergent. Do not use throwaway filters in place of cleanable

filters.

Table 1 — Indoor-Air Filter Data

NOTE:

See unit Installation Instructions if optional filters are used.

When replacing filters, always use the same type and size originally

supplied.

II. 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 neces-

sary. This checkout should not be attempted by anyone who

does not have the required licensing, expertise and/or equip-

ment to do the job properly. Checking and/or cleaning the heat

exchanger involves removing the gas controls assembly and

the flue collector box cover. When finished, the gas controls

assembly must be reinstalled 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.

III. FANS, BELTS, AND FAN MOTOR

At the beginning of each heating and cooling season, check the

condition of fan wheels and housings, belt tension, and fan

motor shaft bearings. No lubrication of condenser or evapora-

tor fan bearings or motors is required or recommended.

IV. EVAPORATOR AND CONDENSER COILS

Inspect and clean the condenser and evaporator coils at the

beginning of each cooling season, or more frequently as con-

ditions require.

Cleaning of the coils should only be done by qualified service

personnel. Contact your dealer for the required annual

maintenance.

V. CONDENSATE DRAIN

The drain pan, condensate trap, and drain line should be

checked and cleaned at the same time the cooling coils are

checked by your dealer.

VI. COMPRESSOR

All compressors are factory-supplied with a normal charge of

the correct type of refrigeration-grade oil and should not re-

quire additional oil.

VII. CONDENSER FAN

The fan must be kept free of all obstructions to ensure proper

cooling. Contact your dealer for any required service.

VIII. ELECTRICAL CONTROLS AND WIRING

Electrical controls are difficult to check without proper in-

strumentation. If there are any discrepancies in the operat-

ing cycle, contact your dealer and request service.

IX. REFRIGERANT CIRCUIT

The refrigerant circuit is difficult to check for leaks without

the proper equipment. If inadequate cooling is suspected,

contact your dealer for service.

X. COMBUSTION AREA AND VENT SYSTEM

The combustion area and vent system should be visually in-

spected before each heating season. The normal accumula-

tion of dirt, soot, rust, and scale can result in loss of effi-

ciency and improper performance if allowed to build up.

WARNING: Never operate your unit without fil-

ters 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 efficiency and, in some cases, fire

that could result in serious injury or death.
