1 Rated 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%.
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
2
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"
on www.lghvac.com.
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745 and
