33. PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all units so that the system operating pressures can be observed.
Tables 17A and 17B outline expected pressures at various indoor and outdoor temperatures.
TABLE 17A
COOLING PRESSURE TABLE
TABLE 17B
COOLING PRESSURE TABLE
Low side pressure ± 4 PSIG
High side pressure ±10 PSIG
Tables 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 reclaimed, system evacuated
and recharged to serial plate instruction.
