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.
