Improved Low Noise

New CassetteCurrentDepending on the height of the installation,

LG air conditioners allow you to vary the speed of the indoor fan motor. When installation is low, the RPM can be reduced but it can be increased when the installation is high to ensure optimum comfort levels. The speed can be adjusted via the slide switch on the back of the LCD wired remote.

High Ceiling OperationWhen cooling rooms in the event of low outdoor temperatures, the BLDC inverter compressor and outdoor BLDC fan motor are used to adjust the air flow and volume, with a view to ensuring efficient operation by allowing the air conditioner to keep operating at -10°C without turning it off.
