Nominal capacity applied with non-ducted indoor units, and 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 Combination Ratio between 95–105%.
Nominal cooling capacity rating obtained with air entering the indoor unit at 80ºF dry bulb
(DB) and 67ºF wet bulb (WB) and outdoor ambient conditions of 95ºF dry bulb (DB) and
75ºF wet bulb (WB).
Nominal heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb
(DB) and 59ºF wet bulb (WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and
43ºF wet bulb (WB).
