Description
This LG single-zone ducted heat pump system pairs outdoor model KUSXE301A with a Multi-Position AHU indoor unit (listed on submittal as KNSLE302A) for one-zone ducted comfort. It’s designed for customers who want ductwork distribution with a modern inverter-driven outdoor unit that can better track changing demand. This is a common “sweet spot” size range for larger single zones like open living areas, combined kitchen/living layouts, or small commercial suites where ducted delivery and stable comfort both matter. For property managers, it’s a straightforward path to ducted comfort without stepping into a full traditional split-system ecosystem.
Performance snapshot (from provided submittal): cooling capacity (min/rated/max) 12,000 / 28,000 / 29,000 BTU/h, and heating capacity (min/rated/max) 13,600 / 27,800 / 30,000 BTU/h. Efficiency is listed at 16.0 SEER2, 10.00 EER2, and 8.5 HSPF2. Outdoor operating range is listed as 14°F–118°F (cooling) and 4°F–64°F (heating). Refrigerant type is R32, with EEV refrigerant control noted in the system data.
For comfort and acoustics, the submittal lists outdoor sound pressure at 52/54 dBA (cooling/heating) and indoor sound pressure at 40/37/35 dBA (high/medium/low). Indoor airflow is listed at 870/730/620 CFM (max high/medium/low), and maximum outdoor air volume is listed at 1,765 CFM. Filter access is also called out with an access panel for a field-supplied 20 x 20 x 1 filter, which is a practical ownership detail for routine maintenance planning.
Electrical and project planning details (from submittal) include a listed power supply of 208-230 V, 60 Hz, 1 phase, with MOP 25 A and MCA 16.6 A. Acceptable operating voltage is listed as 187V–253V. Maximum vertical separation between outdoor and indoor is listed at 49.2 ft. Controls are not an afterthought on this platform: the Multi-Position AHU requires an LG wall controller because it does not have an infrared receiver.
