A.To Use Cooling Charging Chart

Proceed as follows:

1.Remove caps from low-pressure and high-pressure Schrader valve fittings.

2.Using hoses with valve core depressors, attach low- and high-pressure gage hoses to low-pressure and high-pressure service fittings, respectively.

3.Start unit in Cooling mode and let unit run until sys- tem pressure stabilize.

4.Measure and record the following:

a.Outdoor ambient-air temperature (F db).

b.Evaporator inlet-air temperature (F wb).

c.Suction-tube temperature (F) at low-side service fitting.

d.Suction (low-side) pressure (psig).

5.Using “Cooling Charging Charts” compare outdoor- air temperature (F db) with the suction line pressure (psig) to determine desired system operating suction line temperature. See Fig. 41-48.

6.Compare measured suction-tube temperature with

desired suction-tube temperature. Using a tolerance of ± 3° F, add refrigerant if measured temperature is more than 3° F higher than proper suction-tube tem-

perature, or remove refrigerant if actual temperature is more than 3° F lower than required suction-tube temperature.

A.To Use Cooling Charging Chart

This method is to be used in Cooling mode only. Take the out- door ambient temperature and read the suction pressure gage. Refer to appropriate chart to determine what suction temperature should be. If suction temperature is high, add refrigerant. If suction temperature is low, carefully recover

some of the charge. Recheck the suction pressure as charge is adjusted. Example (Fig. 44, Circuit 2):
