When the outside
temperature is below
32°F ( 0°C), we strongly
recommend keeping the
unit plugged in at all
times to ensure smooth
ongoing performance.
NOTE: Room relative humidity should be less than 80%. If the air conditioner operates in excess
of this figure, the surface of the air conditioner may attract condensation. Please set the vertical
air flow louver to its maximum angle (vertically to the floor), and set HIGH fan mode.
