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 capaci-
ties are net with a Combination Ratio between 95–105%.
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 1230. See www.ahrinet.org for information.
3
Cooling range with Low Ambient Baffle Kit (sold separately) is -9.9°F to +122°F.
4
The System Combination Ratio must be between 50–130%.
5
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
6
All communication cable to be minimum 18 AWG, 2-conductor, stranded, shielded, and must comply
with applicable local and national codes. Ensure the communication cable is properly grounded at the
master unit only. Do not ground the ODU-IDU communication cable at any other point.
7
Power wiring cable is field provided and must comply with the applicable local and national codes. See
page 31 for detailed electrical data.
8
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.
