Capacity is rated 0 ft. above sea level, with a 0 ft. level difference between outdoor and indoor units, and the following refrigerant pipe lengths:
LMU180HV: 16.4 ft. x 2 = 32.8 ft.
LMU240HV: 16.4 ft. x 3 = 49.2 ft.
LMU303HV: 16.4 ft. x 4 = 65.6 ft.
LMU363HV: 16.4 ft. x 4 = 65.6 ft.
All capacities are net with a combination ratio between 95 – 105%.
Rated 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).
Rated 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).
