LG's devotion to providing efficient ductless solutions can be seen across their entire catalog. LG's Four-Way Ceiling Cassette systems, such as this KSSCA421A, have several advantages over wall mounted systems. Unobtrusive comfort isn't the only advantage of a ceiling cassette; with four air flow directions, the KSSCA421A provides excellent coverage for large zones. If you're looking for a low-profile alternative to wall mounted ductless heat pump systems, LG's Four-Way Ceiling Cassettes are a great choice. The KSSCA421A also features LGRED° Heat technology, which boasts superior heating performance in extreme cold weather climates.

Product Information:

• 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.


• Inverter Technology: LG's heat pump systems are designed with efficient inverter technology. An electronic expansion valve and a variable speed compressor carefully regulate the refrigerant flow, reducing energy consumption and allowing for consistent, accurate temperatures.


• Quiet Design: The KNSCB421A indoor unit features a cross flow fan that restricts the pressure of air flow and lowers sound levels. Both the outdoor and indoor units enjoy reduced electrical and mechanical sound thanks to their brushless direct current fan motors.


• Integrated Base Pan Heater: The KUSXA421A Outdoor Condenser features a factory-installed base pan heater in the drain pan. This prevents condensate from freezing and damaging the unit in frigid climates.


• Jet Cool: This system features a Jet Cool operation mode for rapid cooling. In this mode, the indoor unit will temporarily adjust the set point and fan speed for 30 minutes to quickly cool your zone.


• Air Flow Options: The KNSCB421A 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.


• Gold Fin Protection: To ensure the reliability and longevity of the KUSXA421A's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.


• Sleep Mode: With the Sleep Mode and Timer functions, you can set the indoor unit to save energy at night. Sleep Mode will incrementally adjust temperature for an hour before the Timer function automatically deactivates the unit.


• Condensate Protection: Condensate overflow can damage your indoor unit and your home. An internal condensate pump with 27.5" of lift protects the KNSCB421A 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 KNSCB421A 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.
