Rated capacity applied with non-ducted indoor units, and is rated 0 ft. above sea level with a 0 ft. level differ-
ence 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 one Branch Distribution Unit is required for system operation; a maximum of two can be
installed per outdoor unit with use of Y-branch accessory (PMBL5620). 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. 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 37.
5
All power wiring / communication cable to be minimum 14 AWG, 4-conductor from the outdoor unit to
the BD unit (Multi F MAX systems only), and 14 AWG, 4-conductor from the BD unit to the indoor unit,
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 37.
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.
