Step 5 — Unit Controls COOLING All compressors have the following internal-protection controls. These units utilize a 2 stage indoor thermostat. With a first stage call for cooling (Y1), the indoor fan (low stage) energizes immediately whereas the contactor energizes after a 5 minute time delay (in case of an initial start-up) starting the compressor (low stage) and the outdoor fan motor.

Step 4 — Outdoor Coil, Indoor Coil, and Condensate Drain Pan Inspect the condenser coil, evaporator coil, and condensate drain pan at least once each year. The coils are easily cleaned when dry; therefore, inspect and clean the coils either before or after each cooling season. Remove all obstructions, including weeds and shrubs, that interfere with the airflow through the condenser coil. Straighten bent fins with a fin comb.
