Page 7
The horizontal vane does not
move.
• Are the horizontal vane and the vertical vane
installed correctly? Page 7
• Is the fan guard deformed?
The
unit cannot be operated
for about 3 minutes when
restarted.
•
This protects the unit according to instruct
ions 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.
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 ow direction changes
during
operation.
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 for 0.5 to 1 hour, the direction
of the air ow is automatically set to horizont
al position to prevent water from condensing
and dripping.
• In the heating operation, if the air ow tem
-
perature
is too low or when defrosting is be-
i
ng done, the horizontal vane is automatically
set to horizontal position.
The operation is stopped for
about 10 minutes in the heat
-
ing
operation.
• Defrosting of the outdoor unit is being
done.
Since this is completed in max.10 minutes,
please wait. (When the outside temperature
is too low and humidity is too high, frost is
formed.)
The
unit starts operation by
itself when the main power
is turned on, though it isn’t
operated 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 operation automatically in the same
mode as the one set with the remote control
-
ler
just before the shutoff of the main power.
Refer
to “Auto restart function” page 4 .
The
indoor unit discolors over
time.
•
Although plastic turns yellow due to the inu-
e
nce of some factors such as ultraviolet light
and temperature, this has no effect on the
product functions.
Multi system
The
indoor unit which is not
operating becomes warm and
a sound, similar to water owing,
is heard from the unit.
• A small amount of refrigerant continues to
ow into the indoor unit even though it is
not
operating.
When heating operation is
selected, operation does not
start right away.
• When operation is started during defrosting
of outdoor unit is done, it takes a few minutes
(max. 10 minutes) to blow out warm air.
Outdoor Unit
The
fan of the outdoor unit
does not rotate even though
the compressor is running.
Even if the fan starts to rotate,
it stops soon.
• When the outside temperature is low dur
-
i
ng cooling operation, the fan operates
intermittently to maintain sufcient cooling
capacity.
Water
leaks from the outdoor
unit.
•
During COOL and DRY 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 op
-
eration
makes water frozen on the outdoor
unit melt and drip down.
White smoke is discharged
from the outdoor unit.
• In the heating operation, vapor generated
by the defrosting operation looks like white
smoke.
