Notes:
- Maximum power input is rated at maximum setting value.
- Maximum lift is 27 inches from bottom of unit. Check valve not included (field supplied).
- See Engineering Manual for sensible and latent capacities.
- Requires an LG wall controller because ducted units do not have infrared receiver.
- Sound Pressure levels are tested in an anechoic chamber under ISO Stan-dard 3745.
- Actual filter sizes may vary.
- At factory fan speed setting.
- Maximum static pressure may result in reduced airflow (CFM).
- All communication cable between (main) outdoor units to indoor units / heat recovery units to be 18 AWG, 2-conductor, twisted, stranded, shielded. Ensure the communication cable shield is properly grounded to the (main) outdoor unit chassis only. DO NOT ground the outdoor unit to indoor units / heat recovery units communication cable at any other point. Wiring must comply with all applicable local and national codes.
