OPERA TING SEQUENCE Cooling — When the first stage (TC1) of the cooling ther- mostat closes, the timer starts. After approximately 3 seconds, the timer expires, energizing the compressor and fan motor no. 1. When the liquid pressure builds to approxi- mately 257 psig (1772 kPa), fan motor no.
Winter Start Control (If Required) — Install Ac- cessory Package 38AE900021. Crankcase Heater — The heater prevents refrigerant migration and compressor oil dilution during shutdown when- ever compressor is not operating. It is wired to cycle with the compressor; the heater is of f when compressor is run- ning, and on when compressor is of f.
