Electrical Controls and Wiring — Electrical controls are difficult to check without proper instrumentation; therefore, if there are any discrepancies in the operating cycle, contactyour dealer and request service. Refrigerant Circuit — The refrigerant circuit is difficultto check for leaks without the proper equipment; therefore, if inadequate cooling is suspected, contact your dealer forservice. Combustion Area and Vent System — The combustion area and vent system should be visually inspected 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. Accumulation on theburner crossover tube can result in the burners firing out of normal time sequence. This delayed ignition is characterized by anespecially loud sound. If your unit makes an unusual or especially loud noisewhen the main burners are lit, shut down the heatingsection and call your dealer. Bodily injury or unit damagemay result. See Fig. 1 and 5 and proceed as follows to inspect the combustion area and power-venting system of your unit. 1. Turn off gas supply and then electrical power to your unit. 2.

Close inspection of all gas pipes leading to and insideyour unit. 4. Adjustment of the air/gas mixture if the burner flames arenot bright blue. (See Fig. 5 and 6 for location of accesspanel and proper flame appearance.) 5. Inspection, and if required, cleaning of the condenser andevaporator coils. 6. Inspection, and if required, cleaning of the evaporatordrain pan. 7. Inspection, cleaning, and lubrication of blower wheelhousing and motor. 8.
