TABLE 2
COOLING PRESSURE TABLE
Air Temperature Entering Outdoor Coil °F (°C)
Low side pressure ± 4 PSIG
High side pressure ± 10 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.
being in the system, the charge should be removed, system evacuated and recharged to serial plate charge weight.
NOTE
1: Return air temperature at 50% R.H.
NOTE
2: Units rated to 131F (55C) outdoor temperature, but higher fan speeds and automatic modulation of the
compressor due to pressure control make pressure readings above 115°F very unstable. Pressure table is
based on low speed condenser fan operation. Fan speed increases above 115°F. Check pressures on unit
at outdoor ambient below 115°F. Set thermostat at least 3° below current room temperature to ensure 100%
comp operation for purpose of pressure testing.
