Features
- 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.
- Inverter Technology
- LG's multi-zone outdoor condensers are designed with powerful, efficient inverter technology. An electronic expansion valve and a variable speed condenser compressor carefully regulate the refrigerant flow, reducing energy consumption.
- Gold Fin Protection
- To ensure the reliability and longevity of the LMU480HHV's heat exchanger, LG employs a Gold Fin coating that prevents corrosion and improves durability.
- 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.
- Jet Cool
- These LG mini split indoor units feature a Jet Cool operation mode for rapid cooling. In this mode, an indoor unit observes a set point of 64 degrees Fahrenheit while the fan operates at maximum speed for 30 minutes to quickly cool your zone.
- Swirl Wind Mode
- Exclusive to ceiling cassette models is Swirl Wind, which automates both air flow direction and fan speed to produce steady comfort throughout any zone.
- Improved Air Quality
- These mini split indoor units include anti-fungal filters to keep your air clean. These filters capture contaminants like dust and bacteria, and they are washable to ensure long term air quality.
- Dehumidify
- LG's multi-zone 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 on a mini split indoor unit, the 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.
- Supply Air Branch Duct Connections
- LG cassette units feature designated cutouts for a branch duct, giving you the ability to duct up to 1/2 of the unit's airflow capacity to adjacent spaces.
- Recommended line set sizes for indoor unit connectivity:
- LCN097HV4: 1/4" x 3/8" Line Set (Qty 2)
- LCN127HV4: 1/4" x 3/8" Line Set (Qty 2)
- LCN188HV4: 1/4" x 1/2" Line Set
- A branch box with a 3/8" x 3/4" line set connection is also required. Additional branch boxes and line sets may be required based on your configuration.
- All LG branch boxes systems require a min of 16.4 feet of line set between the condenser and the branch box, from the branch box to the distribution box and from the distribution box to the indoor unit.

- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Branch Box - An LG branch box is required to connect this condenser to LG mini split indoor units.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing. We recommend locally purchased PVC hard pipe for the condensate drain on cassette and concealed duct 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.
- Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.
- 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.
LG's devotion to providing efficient ductless solutions can be seen across the Multi F line. This ceiling cassette ductless heat pump system pairs a powerful LMU480HHV outdoor condenser with very efficient ceiling cassette indoor units. LG's Multi F ceiling cassette indoor units feature four air outlets which allow them to provide consistent air flow to the farthest reaches of large rooms. In addition to providing excellent coverage, the ceiling cassette indoor units also feature an exceptionally low profile. When installed, a grille less than 1\" thick is the only visible clue that your room is receiving efficient heating and cooling from a ductless heat pump system.
