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 75F.........................
Suction Pressure 70 psig...........................
Suction Temperature should be 48F..................
(Suction temperature may vary 5F.)
If a charging device is used, temperature and pressure readings
must be accomplished using the char ging c harts.
