TABLE 2.1

Cooling Pressures

Air Temperature Entering Outdoor Coil °F

Low side pressure ± 4 PSIG
High side pressure ± 10 PSIG

Tables are based upon rated CFM (airflow) across the evaporator coil. If there is any doubt as to correct operating
charge being in the system, the charge should be removed and system evacuated and recharged to serial plate
charge weight.

NOTE:

Pressure table based on high speed condenser fan operation. If condensing pressures appear elevated

check condenser fan wiring. See “Condenser Fan Operation”.
