TABLE 12

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 condenser fan wiring.

See

Condenser Fan Operation

on page 28.

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