TABLE 5A
COOLING PRESSURE TABLE
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, 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”.
