1
Nominal 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%. (Nominal capacity is outside the scope
of AHRI Standard 210/240.)
Nominal cooling capacity rating 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).
Nominal heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and
59ºF wet bulb (WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
2
Rated capacity is certified under AHRI Standard 210/240. See www.ahrinet.org for information.
3
The System Combination Ratio must be between 50–130%.
4
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745
5
All communication cable to be minimum 18 AWG, 2-conductor, stranded, shielded, and must comply
with applicable local and national codes.
6
Power wiring cable is field provided and must comply with the applicable local and national codes. See
below for detailed electrical data.

Refer to the Refrigerant Piping section of this manual for correct line sizing. Contractor must use LG
manufactured Y-Branch and Header Kits only. Designer must verify refrigerant piping design configura-
tion using LG’s computerized refrigerant piping (LATS Multi V) software to validate the pipe design.

Voltage tolerance is ±10%.
Maximum allowable voltage unbalance is 2%.
MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOP) is calculated as follows: (Largest motor FLA x 2.25) + (Sum of
other motor FLA) rounded down to the nearest standard fuse size.
