For comfortable use, do not turn off the
power circuit breaker during seasonal use of
the HEATING OPERATION.
• The outdoor unit stops.
This is because the indoor temperature has
reached the set temperature.
The indoor unit is in the FAN OPERATION.
COOLING OPERATION
(AUTOMATIC COOLING OPERATION):
Lower the set temperature.
HEATI NG OPERATION
(AUTOMATIC HEATING OPERATION):
Raise the set temperature.
The operation starts after a while when the
air conditioner is in normal condition.
• The remote controller displays “ ”,
and airflow stops.
This is because the air conditioner automati-
cally 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 condi-
tioner 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 stops the
operation 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 (HEAT-
ING OPERATION), the wind from the air con-
ditioner 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 PRO-
GRAM DRY OPERATION.)
When the room temperature reaches the set
temperature during the HEATING OPERA-
TION, 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 DIS-
PLAY 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 con-
trolled so it is horizontal direction after the
operation starts or when the indoor temper-
ature is higher than the set temperature to
prevent air discharge directly toward your
body.
After a while, the swing operation starts.
(Refer to “MOVEMENT OF THE HORIZON-
TAL BLADE” page 8.)
• The airflow direction display of the
remote controller differs from the actual
operation of the horizontal blades.
<COOL 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 pre-
vent condensation on the horizontal blades.
<HEATING OPERATION>
This is because the airflow direction is con-
trolled so it is horizontal direction after the
operation starts or when the indoor temper-
ature 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 “MOVEMENT OF THE HORIZON-
TAL BLADE” page 8.)
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 CON-
DITIONER
• When humidity is high during the COOL-
ING 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 neces-
sary 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.
