HOT ! LG KNUDB121A Multi/Single Zone Ceiling Cassette with 12000 BTU Cooling Capacity, 13800 BTU Heating Capacity and Remote in White

LG\'s devotion to providing efficient ductless solutions can be seen across the Multi F line of indoor units. Part of the Four-Way Ceiling Cassette lineup of mini split indoor units, the unit combines powerful multi-directional air flow with a low-profile design, allowing you to heat and cool large rooms discreetly. Thanks to the recessed installation design, a grille less than 1\" thick is the only visible part of the installed unit .

• AHRI Certified


• Jet Cool


• Sleep Mode

Enhanced Connectivity

LG\'s new R-32 mini split units require a 5-conductor cable (Not Included) instead of the standard 4-conductor, improving communication reliability and enabling a new leak detection feature.

Air Flow Options

The unit offers two automated air flow options: Swing Mode and Swirl Wind mode. Any of these modes can be activated to provide optimal circulation specific to your home.

Quiet Design

The unit can operate at volumes as low as 30 dB thanks to its advanced fan motor. The brushless direct current motor reduces electrical and mechanical sound while providing powerful air movement.

Automated Operation

Auto operation mode continually compares your zone\'s current and desired temperatures and uses that data to intelligently adjust the unit\'s fan speed and refrigerant flow to provide optimal comfort.

Condensate Protection

Condensate overflow can damage your indoor unit and your home. An internal condensate pump with 27.5\" of lift protects the unit through reliable, effective condensate removal.

Dehumidify

LG\'s indoor units include a dehumidifying operation mode. In this mode, the unit\'s internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Improved Air Quality

The unit features an anti-fungal filter to keep your air clean. This filter captures contaminants like dust and bacteria, and it is washable to ensure long term air quality.

Hot-Start

When the hot-start function is enabled, the unit\'s fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.
