EEV: Electronic Expansion Valve, IDU: Indoor Unit, ODU: Outdoor Unit. Unit comes with a dry helium
charge.
This data is rated 0 ft above sea level, with 24.6 ft of refrigerant line per indoor unit and a 0 ft level
difference between outdoor and indoor units.
Cooling capacity rating obtained with air entering the indoor coil at 80ºF dry bulb (DB) and 67ºF wet bulb
(WB); and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and 60ºF wet bulb
(WB); and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
Power Input is rated at high speed.
