Rated capacity applied with non-ducted indoor units, and is rated 0 ft. above sea level with 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 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 should be connected. For allocated capacity information, see the combination tables in
the “Multi F / Multi F MAX Combination Data Manual” on www.lg-dfs.com. For performance
data, see “Multi F / Multi F MAX Performance Data Manual” on www.lg-dfs.com.

Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
These values can increase due to ambient conditions during operation.

All power wiring / communication cable to be minimum 16 AWG from the outdoor unit to
the BD unit (Multi F MAX systems only), 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 11.
