LG's devotion to providing efficient ductless solutions can be seen across the Multi F line of indoor units. The mini split indoor unit is designed for installation in short-run ducting with mid static pressures. Concealed duct indoor units mean that you can add mini split zones with no visible indoor units. With the mid static ducted unit, a small air register is the only clue that a mini split is providing effective heating and cooling to your space.
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.
Quiet Design
The unit can operate at volumes as low as 26 dB thanks to its advanced fan motor. The brushless direct current motor reduces electrical and mechanical sound while providing powerful air movement.
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 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.
Improved Air Quality
The unit 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.
Hot-Start
When the Hot-Start function is enabled, the 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.
