Acceptable operating voltage: 187V-253V. 2. Piping lengths are equivalent. 3. Sound Pressure levels are tested in an anechoic chamber under ISO Standard 3745. 4. All power supply wiring to the outdoor unit is field supplied, solid or stranded. The power wiring and the communication wiring from the outdoor unit to the indoor unit is field supplied and must be stranded, shielded or unshielded (if shielded, it must be grounded to the chassis of the outdoor unit only). All wiring must comply with applicable local and national codes. a. Power Supply Wiring to ODU: (No. x AWG): 3 x 14 for 9/12k, 3 x 12 for 18k units. b. Power Wiring / Communication Wiring from Outdoor Unit to Indoor Unit: (No. x AWG) 3 x 14 / 2 x 18. 5. See Engineering Manual for sensible and latent capacities. 6. Power wiring cable size must comply with the applicable local and national code. 7. The indoor unit comes with a dry helium charge. 8. This data is rated 0 ft. above sea level, with 24.6 ft. of refrigerant line and a 0 ft. level difference between outdoor and indoor units. 9. Must follow installation instructions in the applicable LG installation manual. 10. Multi-compatible 18k IDUs include socket adapters for refrigerant pipe connections with single zone systems.
