Contact your dealer for the required periodic maintenance. 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. Evaporator and Condenser Coils — Cleaning of the coils should only be done by qualified service personnel. Contact your dealer for the required annual maintenance. 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-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. Condenser Fan 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.

Fig.5—FilterAccessPanel—VerticalSupplyShown 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. 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. 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. 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. 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. Components in heat section may be hot after unit has been started up. When observing flame, be careful not to get close to or touch heating components or serious personal injury may result. 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. Unit Panels — After performing any maintenance or service on the unit, be sure 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: 1. Inspection of all flue product passages — including the burners, heat exchanger, and flue collector box. 2. Inspection of all combustion-and ventilation-air passages and openings. 3. Close inspection of all gas pipes leading to and inside of your unit. 4. Inspection and, if required, cleaning of the condenser and evaporator coils. 5. Inspection and, if required, cleaning of the evaporator drain pan. 6. Inspection and cleaning of blower wheel housing and motor. 7. Inspection of all supply-air and return-air ducts for leaks, obstructions, and insulation integrity. Any problems found should be resolved at this time. 8. Inspection of the unit base to ensure that no cracks, gaps, etc., exist which may cause a hazardous condition. 9. Inspection of the unit casing for signs of deterioration. 10. Inspection of all electrical wiring and components to assure proper connection. 11. Inspection for leaks in the refrigerant circuit. Pressure- check to determine appropriate refrigerant charge. 12. Inspection of compressor oil level. 13. Operational check of the unit to determine working conditions. Repair or...
