Capacity is rated with non-ducted indoor units, 0 ft. above sea level, with a 0 ft. level
difference between outdoor and indoor units, and the following refrigerant pipe lengths:
LMU183HV: 16.4 ft. x 2 = 32.8 ft.
LMU243HV: 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 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 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).

At least two indoor units must be connected. For allocated capacity information, see
the combination tables in the "Multi F / Multi F MAX Combination Data Manual" on www.
lghvac.com. For performance data, see "Multi F / Multi F MAX Performance Data Manual"
