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.

Low Ambient Operations

This outdoor unit supports cooling operations down to 14 degrees Fahrenheit and heating operations down to -13 degrees Fahrenheit. There is also a defrost feature, which removes frost from the condenser coil in frigid conditions.

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.

Quiet Design

Thanks to a brushless direct current motor and a twin rotary compressor, the unit is significantly quieter than traditional air conditioning systems. These components reduce mechanical sound, electrical sound, and vibrations within the unit.
