33. PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all
units so that the system operating pressures can be
observed. Table 13 outlines expected pressures at
various indoor and outdoor temperatures.
34. REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit performance will occur
with a refrigerant charge resulting in a suction line
temperature (6” from compressor) as shown in
Table 14.
The suction line temperatures in Table 14 are based
upon 80 degrees F dry bulb / 67 degree wet bulb
(50% R.H.) temperature and rated airflow across the
evaporator during cooling cycle.
Total system charge for these models can be found in
Table 1.
