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 a service center.
■
Do not block the air intake and outlet of the unit. If either is obstructed, the
unit will not work well, and may be damaged.
Do not 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.
