■ CLEANING BEFORE AND AFTER
SEASONAL USE
WHAT TO DO WHEN START UP AFTER
A LONG STOP
Confirm the following.
• Check that the air inlet and outlet of indoor unit
is not blocked.
Remove any obstacle.
Obstacles may cause a reduction in the fan speed,
which may decrease functionality, cause an increase
in operation noise, or a malfunction of the equipment.
Clean the air filter and outside panel
• After cleaning the air filter, make sure to attach it.
(Refer to "8. MAINTENANCE" on page 6.)
• For information on how to install, remove, or clean
a optional sold air filter, refer to the user's manual
attached to the air filter.
• After cleaning, perform FILTER SIGN RESET after
turning on the power.
Turn on the power circuit breaker at least 6 hours
before operation.
• This is required in order to activate the air conditioner
smoothly, and to protect air conditioner.
• The display on the remote controller will be
shown when the power circuit breaker is turned on.
WHAT TO DO TO STOP THE AIR
CONDITIONER FOR A LONG PERIOD
Turn on FAN OPERATION for a half day on the fine
day and dry the indoor unit.
• This can prevent the causes of mould.
Turn off the power circuit breaker.
• During the power circuit breaker is turned on, some
watts of electricity is being used even if the air
conditioner is not operating.
Turn off the power circuit breaker for saving energy.
• The display on the remote controller will vanish when
the power circuit breaker is turned off.
Clean the air filter and outside panel
• Be sure to replace the air filter to its original place after
cleaning. (Refer to "8. MAINTENANCE" on page 6.)
For information on how to install, remove, or clean an
optional sold air filter, refer to the user's manual
attached to the air filter.
NOTE
-,g.
The inside of the air conditioner may become contaminated
after several seasons of use, potentially causing
performance degradation and water leakage.
Ask your local dealer for details on cleaning the inside of
the indoor unit. This operation requires a qualified service
person.

9. NOT MALFUNCTION OF THE
AIR CONDITIONER
1. THE AIR CONDITIONER DOES NOT OPERATE
• The flow into the indoor unit stops.
This is because the indoor temperature has reached
the set temperature.
The indoor unit is in the FAN OPERATION.
COOLING OPERATION
Lower the set temperature.
The operation starts after a while when the air
conditioner is in normal condition.
2.
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.
3. 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.
4.
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.
5. NOISE OF AIR CONDITIONERS
• A ringing sound after the indoor unit starts.
This sound is generated when the motors for driving
the horizontal blades are working. It will quiet down
after about a minute.
• A "Pishi-pishi" squeaking sound is heard when
the air conditioner is in operation or after the
stop of operation.
Expansion and contraction of resin parts caused by
temperature change makes this noise.
