This unit comes with a dry nitrogen charge.
This data is rated 0 ft above sea level, with 25 ft of refrigerant line per indoor unit and a 0 ft
level difference between outdoor and indoor units. All capacities are net with a combina-
tion ratio between 95-105%.
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).
Heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and
outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
