TABLE 3A – 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”.
