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 21.
* Operating at these conditions would be outside the compressor operating envelope and is not recommended.
