All LED lamps on the indoor unit are blinking.
• Are the horizontal vanes installed correctly?

The horizontal vane does not move.
• Are the horizontal vane and the vertical vanes installed correctly?

The unit cannot be operated for about 3
minutes when restarted.
• This protects the unit according to instructions from the micropro-
cessor. Please wait.
The fan stops during the DRY operation.
• In DRY operation, the unit operates using the same refrigerant
circuit as in COOL operation. DRY operation time has to be re-
duced in order to lower humidity without much room temperature
decreasing. So the compressor sometimes stops, and at the
same time the indoor fan stops. This prevents water condensed
on the heat exchanger from evaporating again.
Mist is discharged from the air outlet of the
indoor unit.
• The cool air from the unit rapidly cools moisture in the air inside
the room, and it turns into mist.
The swing operation of the HORIZONTAL
VANE is suspended for a while, then restarted.
• This is for the swing operation of the HORIZONTAL VANE to be
performed normally.
The air flow direction changes during opera
-
tion.
The direction of the horizontal vane cannot be
adjusted with the remote controller.
• When the unit is operated in COOL or DRY mode, if the op-
eration continues with air blowing down for 0.5 to 1 hour, the
direction of the air flow is automatically set to upward position to
prevent water from condensing and dripping.
The unit starts operation by itself when the
main power is turned on, though it isn’t oper-
ated with the remote controller.
• These models are equipped with an auto restart function. When
the main power is turned off without stopping the unit with the
remote controller and is turned on again, the unit starts oper-
ation automatically in the same mode as the one set with the
remote controller just before the shutoff of the main power.

.
The indoor unit discolors over time.
• Although plastic turns yellow due to the influence of some factors
such as ultraviolet light and temperature, this has no effect on
the product functions.
Outdoor Unit
Water leaks from the outdoor unit.
• During COOL and DRY operations, pipe or pipe connecting sec-
tions are cooled and this causes water to condense.
Remote controller
The display on the remote controller does not
appear or it is dim. The indoor unit does not
respond to the remote control signal.
• Are the batteries exhausted?

• Is the polarity (+, -) of the batteries correct?

• Are any buttons on the remote controller of other electric appli-
ances being pressed?

HEN YOU THINK THAT TROUBLE HAS OCCURRED
Even if these items are checked, when the unit does not recover from the trouble, stop using the air condi-
tioner and consult your dealer.
