• The unit may be damaged if lightning strikes.
After the air conditioner is used for several seasons, perform inspection and maintenance in

or clog the drain passage, and cause water to leak from the indoor unit. Consult your dealer for
inspection and maintenance, which require specialized knowledge and skills.
Do not operate switches with wet hands.

mold. It is therefore recommended to clean air fi lters every 2 weeks.
