Details
LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This concealed duct heat pump system pairs a powerful KUMXA301A outdoor condenser with three concealed duct indoor units. These units are designed for installation in short-run ducting with low static pressures. With this system, you can add quiet zoned comfort to your home without mounting anything on your walls. Like a central system, small air registers are all that your guests will see with this concealed duct heat pump system. This system 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: Thanks to a brushless direct current fan motor, both the outdoor and indoor units in this system produce less mechanical and electrical noise, allowing them to provide comfort that doesn't disrupt your home.
- Integrated Base Pan Heater: Base pan heaters come factory installed on all LGRED° outdoor condensers in order to mitigate the risk of damage caused by freezing condensate.
- Gold Fin Protection: To ensure the reliability and longevity of the KUMXA301A's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
- 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.
- Sleep Mode: With the Sleep Mode and Timer functions, you can set this 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 indoor 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.
- Hot-Start: When the Hot-Start function is enabled, the indoor 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.
- Improved Air Quality: These mini split indoor units include 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.
- Recommended line set sizes for indoor unit connectivity: KNMKB091A: 1/4" x 3/8" Line Set (Qty 3)
