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 airflow arrows on the filter frame. Fig.2—GasHeating/ElectricCoolingUnit(InternalView) 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.

WARNING: 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 efficiency and, in some cases, fire. 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 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. III. 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. 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. —3— V. 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. VI. 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. The service person must be certain the proper oil level is maintained in the compressor when it is installed and running. VII. Condenser Fan WARNING: 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. —4— 55 55 STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 STEP 7 STEP 6 STEP 10 STEP 9 STEP 8 Fig.3—To Light Unit -5 55 55 STEP 1 STEP 2 STEP 3 STEP 4 STEP 5 STEP 6 STEP 7 Fig.4—To Shut Unit Off -6 ACCESS PANEL FILTER ACCESS PANEL* ACCESS PANEL FILTER ACCESS PANEL* *Foraccessoryfilterrack.

Electrical Controls and Wiring Electrical controls are difficult to check without proper instrumentation; therefore, if there are any discrepancies in the operating cycle, contact your dealer and request service. IX. Refrigerant Circuit The refrigerant circuit is difficult to check for leaks without the proper equipment; therefore, if inadequate cooling is suspected, contact your local dealer for service. X. Combustion Area and Vent System The combustion area and vent system should be inspected visually before each heating season. The normal accumulation of dirt, soot, rust, and scale can result in loss of efficiency and improper performance if allowed to build up. CAUTION: If your unit makes an especially loud noise when the main burners are ignited, shut down the heating section and call your dealer. Proceed as follows to inspect the combustion area and power- venting system of your unit. 1. Turn off electrical power and gas supply to your unit. 2. Remove burner access panel. (See Fig. 1.) 3. Using a flashlight, carefully inspect the burner areas for dirt, soot, rust, or scale. See Fig. 2. CAUTION: If dirt, soot, rust, or scale accumulations are found, call your dealer and do not operate your heating section. 4. When you have completed your inspection, follow the start-up procedures in this manual to restore your unit to operation. 5. Observe unit heating operation.
