If the Cool mode is stopped and then started immediately, cool air comes
out after about 3 minutes to protect the compressor of the outdoor unit.

࡛
If the refrigerant pipe is too long, the cooling and heating efficiencies
may be decreased. Avoid exceeding the maximum pipe length.
The air conditioner
makes strange
noises.

Unpleasant odours
permeate the room.

If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
