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 instructions.
 75°F outdoor temperature condenser fan motor is running on low speed.
When the system is operating in the dehumidification mode, the suction pressure will be reduced by 4 to 8 psig and the discharge
pressure will be reduced by 19 to 22 psig.
