Features
- 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 KNUDB181A 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.
- Gold Fin Protection
- To ensure the reliability and longevity of the KUSXB181A's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
- 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 KNUDB181A 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.
- 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 KNUDB181A 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 KNUDB181A 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.
- 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 - LG's new R-32 mini split units require a 14 AWG 5-conductor cable. This cable 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. All Mini Split Systems require one Primary Mini Split Installation Kit.
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 KSUDB181A, have several advantages over wall mounted systems. By recessing the KSUDB181A indoor unit, a 1.5" thick grille is the only part of the equipment that stays visible. Unobtrusive comfort isn't the only advantage of a ceiling cassette; with four air flow directions, the KSUDB181A 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.

SEER2
The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. EER2 (Energy Efficiency Ratio) is a measurement of cooling efficiency under fixed conditions. It is useful for comparing units that will operate consistently under one set of conditions (e.g. server room). The higher the EER2, the more efficient the system.
