Notes

  1. 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/communication cable to be minimum 14 American wire gage (AWG), 4- conductor, stranded, shielded or unshielded wire and must comply with applicable local and national code. If shielded, the wire must be grounded to the chassis at the outdoor unit only.
  5. Power wiring cable size must comply with the applicable local and national code.
  6. The indoor unit comes with a dry helium charge.
  7. This data is rated 0 ft. above sea level, with 25 ft. of refrigerant line and a 0 ft. level difference between outdoor and indoor units.
  8. Must follow installation instructions in the applicable LG installation manual.
  9. If the optional low ambient wind baffle (ZLABGP04A) is used, one wind baffle is required for each ODU fan.
  10. Dehumidification rate is based on high speed airflow.
  11. 18k, 24k, and 36k IDU units have ECM fan that automatically adjusts throughout the ESP (External Static Pressure) range. Therefore, there is no default ESP value for these units.
  12. 18k and 24k VAHUs are supplied with socket adapters for pipe transitions.
  13. Electric heater accessory available in 3kW, 5kW, 8kW, 10kW, 15kW, and 20kW capacities. Refer to the engineering manual for details.
  14. Controller not included
