• The remote controller displays "
",
and airflow stops.
This is because the air conditioner
automatically switches to the DEFROST
OPERATION to prevent a decrease in
heating capacity when frost on the outdoor
unit increases.
After maximum 10 minutes, the air
conditioner returns to its original operation.
II. THE OPERATION SOMETIMES STOPS
• The remote controller displays "U4" and
"U5", and the operation stops. However, it
will restart in a few minutes.
This is because communication between the
indoor and outdoor units or indoor units and
remote controllers is shut off and stopped
due to noise caused by devices other than
the air conditioner.
When the electrical noise decreases, the air
conditioner automatically restarts.
III. THE FAN SPEED IS DIFFERENT FROM THE
SETTING
• Pressing the fan speed control button
does not change the fan speed.
During the COOLING OPERATION, the low
fan speed or a gentle wind is used to prevent
the discharge of melt water.
During the DEFROST OPERATION
(HEATING OPERATION), the wind from the
air conditioner stops to prevent air discharge
directly toward your body. After a while, the
fan speed can be changed.
(The fan speed cannot be set for the
PROGRAM DRY OPERATION.)
When the room temperature reaches the set
temperature during the HEATING
OPERATION, the outdoor unit stops and the
indoor unit goes into gentle wind.
It takes some time until the fan speed
changes.
Raise the set temperature.
After a while, the fan speed changes.
IV. THE AIRFLOW DIRECTION IS DIFFERENT
FROM THE SETTING, OR THE AIRFLOW
DIRECTION IS DIFFERENT FROM THE
DISPLAY ON THE REMOTE CONTROLLER
• The horizontal blades do not swing when
the remote controller displays the swing
operation.
<HEATING OPERATION>
This is because the airflow direction is
controlled so it is horizontal direction after
the operation starts or when the indoor
temperature is higher than the set
temperature to prevent air discharge
directly toward your body.
After a while, the swing operation starts.
(Refer to "
• The airflow direction display of the
remote controller differs from the actual
operation of the horizontal blades.
<COOLING and PROGRAM DRY
OPERATIONS>
When the operation in a downward airflow
direction is set, the airflow direction differs
from the display for a period of time to
prevent condensation on the horizontal
blades.
<HEATING OPERATION>
This is because the airflow direction is
controlled so it is horizontal direction after
the operation starts or when the indoor
temperature is higher than the set
temperature to prevent air discharge
directly toward your body.
After a while, the airflow direction changes
to the set direction.
(Refer to "
V. HORIZONTAL BLADES DO NOT CLOSE
• The horizontal blades do not close even
when operation stops.
This is because the horizontal blades close
once airflow from the air conditioner stops.
After a while, the horizontal blades close.
VI. WHITE MIST COMES OUT OF THE AIR
CONDITIONER
• When humidity is high during the
COOLING OPERATION. (In oily or dusty
places)
If the inside of an indoor unit is extremely
contaminated, the temperature distribution
inside a room becomes uneven.
It is necessary to clean the inside of the
indoor unit.
Ask your local dealer for details on cleaning
the indoor unit.
This cleaning requires a qualified service
person.
Check the usage environment.
