Table 6: Single Frame 460V Outdoor Units.
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
The System Combination Ratio must be between 50–130%.
4
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
5
Communication cable between Master ODU to Slave ODU(s), and Master ODU to IDUs / HRUs to be
18 AWG, 2-conductor, twisted, stranded, shielded. Ensure the communication cable shield is properly
grounded to the Master ODU chassis only.
Do not ground the ODU to IDUs / HRUs communication
cable at any other point. Wiring must comply with all applicable local and national codes.
6
Power wiring is field provided, solid or stranded, and must comply with the applicable local and nation-
al codes. See page 21 for detailed electrical data.
7
LG requires that LATS software be used on all projects to ensure correct line sizing. Designer must
verify the shop drawing design against the as built design using LATS. Contractor must also use LG
manufactured Y-Branch and Header Kits only.
