CAUTION
• Improper installation of the micro mesh stainless filter could result in malfunction. Filter cleaning
operation can not be performed properly and the (CLEAN) indicator blinks.
• Do not operate the air conditioner without the micro mesh stainless filter.
Dust goes in the gap of the heat exchanger as well as inside the appliance and may cause unpleasant smell
on the heat exchanger or could result in malfunction.
• Be extra careful not to cut your hand with the fin of the heat exchanger when removing and reattaching
the micro mesh stainless filter.
