TABLE 6

Cooling Pressure

–

Standard Airflow

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”.

* Operating at these conditions would be outside the compressor operating envelope and is not recommended.

TABLE 7

Cooling Pressure

Balanced Climate Airflow

Air Temperature Entering Outdoor Coil °F

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

Tables are based upon Balanced Climate 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
