Notes:
1. Condensing unit only ratings are in accordance with ARI standard 365. Full load ratings are at 95°F entering air temperature, and refrigerant conditions entering the
condensing unit of 45°F saturated and 60°F actual temperature. Part load ratings are at 80°F entering air temperature and refrigerant conditions entering the condensing
unit of 50°F saturated suction and 65°F actual temperature.
