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 instructions.
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 14.
