• This protects the unit according to instructions
from the microprocessor. Please wait.
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.

• When the heating operation starts after the
defrosting operation, vapor generated from the

The swing operation of the horizon-
tal vane is suspended for a while,
then restarted.
• This is for the swing operation of the horizontal
vane to be performed normally.
When swing is selected in cool/
dry/fan mode, the lower horizon-
tal vane does not move.
• It is normal that the lower horizontal vane does
not move when swing is selected in cool/dry/fan
mode.
Theairowdirectionchanges

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 operation continues with air blowing down
for0.5To1hour,thedirectionoftheairowis
automatically set to upward position to prevent
water from condensing and dripping.
• Intheheatingoperation,iftheairowtempera-
ture is too low or when defrosting is being done,

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 o without stopping the unit with the
remote controller and is turned on again, the
unit starts operation automatically in the same
mode as the one set with the remote control-
ler just beforetheshutoof the main power.

Symptom Explanation & Check Points
Outdoor Unit
The fan of the outdoor unit does
not rotate even though the com-
pressor is running. Even if the
fan starts to rotate, it stops soon.
• When the outside temperature is low during
cooling operation, the fan operates intermittently
tomaintainsucientcoolingcapacity.
Waterleaksfromtheoutdoor
unit.
• During cool and dry mode operations, pipe or
pipe connecting sections are cooled and this
causes water to condense.
• In the heating operation, water condensed on
the heat exchanger drips down.
• In the heating operation, the defrosting operation
makesiceformingontheoutdoorunitmeltand
drip down.
