Features & Bundle Details

Overview for LG KUMXB181A KNMKB091A KNMKB121A

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 KUMXB181A outdoor condenser with two 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.
  • 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.
  • Gold Fin Protection
  • To ensure the reliability and longevity of the KUMXB181A'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
  • KNMKB121A: 1/4" x 3/8" Line Set
  • Product Note
    This product requires the following accessories for installation:
    • Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
    • Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
    • Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
    • Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.
    • Adding these accessories to your order will provide a complete, ready-to-install mini split system. You will need a line set for each additional indoor unit.
    LG products include a 10-year warranty with the requirement that installation is completed by a licensed contractor and that the product is registered at https://lg-dfs-warranty.com/ within 60 days of installation.
