To Use Cooling Charging Chart, Standard Unit
Take the outdoor ambient temperature and read the suction pressure gage. Refer to charts 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. 57):
Outdoor Temperature . . . . . . . . . . . . . . . . . . . . . . . . . 75°F Suction Pressure . . . . . . . . . . . . . . . . . . . . . . . . . . . 70 psig Suction Temperature should be . . . . . . . . . . . . . . . . . . 48°F (Suction temperature may vary ± 5°F.)
If a charging device is used, temperature and pressure readings must be accomplished using the charging charts.
