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).
2
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" on www.lghvac.com.
3
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745 and are the same
in both cooling and heating mode. These values can increase due to ambient conditions during operation.
4
Power wiring to the outdoor unit is field supplied, solid or stranded, and must comply with the ap-
plicable local and national codes. For detailed information, please refer to electrical characteristics on
page 19.
5
All power wiring / communication cable to be minimum 14 AWG, 4-conductor from the outdoor unit to
the indoor units, stranded, shielded or unshielded (if shielded, it must be grounded to the chassis of
the outdoor unit only), and must comply with applicable local and national codes. For detailed electrical
information, please refer to electric characteristics on page 19.
6
Piping lengths are equivalent.
7
Installation of an optional Low Ambient Wind Baffle Kit will allow operation down to -4°F in cooling mode.
