Rated capacity applied with non-ducted indoor units, and is rated 0 ft. above sea level with a 0 ft. level differ-
1
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 Cooling range with Low Ambient Wind Baffle Kit (sold separately) is -4°F to +118°F.
At least one Branch Distribution Unit is required for system operation; a maximum of two can be
3
installed per outdoor unit with use of Y-branch accessory (PMBL5620). At least two indoor units should
be connected. For allocated capacity information, see the combination tables in the "Multi F / Multi F
MAX with LGRED Combination Data Manual" on www.lg-dfs.com. For performance data, see "Multi F /
Multi F MAX with LGRED Performance Data Manual" on www.lg-dfs.com.

Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745. These values can
4
increase due to ambient conditions during operation.
5 Power wiring to the outdoor unit is field supplied, solid or stranded, and must comply with the applica-
ble local and national codes. For detailed information, please refer to electrical characteristics on page
30.
6 All communications / connection (power) cable to be minimum 16 AWG from the outdoor unit to the
BD unit, and 18 AWG 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 30.
