Troubleshooting
If your air conditioner does not work properly, first check the following points before requesting service. If it still
does not work properly, contact your dealer or service center.
Tips for Energy Saving
Do not • Block the air intake and outlet of the unit. If they are obstructed, the
unit will not work well, and may be damaged.
• Let direct sunlight into the room. Use sunshades, blinds or curtains. If the
walls and ceiling of the room are warmed by the sun, it will take longer to
cool the room.
Do • Always try to keep the air filter clean. (Refer to ‘‘Care and Cleaning’’.)
A clogged filter will impair the performance of the unit.
• To prevent conditioned air from escaping, keep windows, doors and any
other openings closed.
