Operation Hints
Adjust room temperature properly. Set the
temperature 1°C higher (Cooling Operation) or
2°C lower (Heating Operation) than actually de-
sired.
Approximately 10% of electricity costs can be
saved.
Prevent wastage with the Timer. Use Timer
when sleeping or going out to save electricity
cost.
Clean the air filter regularly. Blockage in the air
filter reduces the airflow and lowers the cooling
or heating. Clean at least once every 2 weeks.
Otherwise, about 6% of electricity cost will be
wasted.
Do not block the air outlet vents at outdoor unit.
Otherwise, it will lower the cooling or heating
performance.

ENGLISH
Make sure that the doors and windows are shut.
Otherwise, cooling and heating performance
will be reduced and electricity cost is wasted.
Proper airflow direction adjustment. Set the air-
flow direction louvers horizontal for Cooling
Operation and downwards for Heating Opera-
tion. Operation result will be better.
Keep blinds or curtains closed. Do not let sun-
shine enter the room directly. About 5% of elec-
tricity cost can be saved.
Use insulating material for better performance.
Use insulating material during construction or
renovations. It will save electricity cost.

During Soft Dry Mode
Operation, the air condi-
tioner stops.
QIs it okay? AThis is the answer.
Air conditioner has been re-
started, but does not
operate for 3 minutes.
During Automatic Airflow
Volume setting, indoor fan
stops occasionally.
Operation stops for about
12 minutes during heating.
(The operation lamp
blinks.)
It seems that fog is coming
out from the air
conditioner.
Airflow does not begin
immediately during Heat-
ing Operation.
The room has a peculiar
odour.
This is to protect the air conditioner. Wait until the
air conditioner begins operating.
Soft Dry Mode Operation is a very gentle cooling
operation consisting primarily of dehumidifying.
The air conditioner may stop for approximately 6
minutes in order to prevent overcooling.
If the room temperature rises again, the operation
will recommence.
If the airflow begins before its temperature be-
come warm, it will cause an undesired cooling ef-
fect. In order to prevent this, the airflow will not
begin until it is sufficiently warm.
(The operation lamp will blink until the airflow
begins.)
This may be a damp smell exuded by the walls,
carpet, furniture or clothing in the room.
Condensation occurs when the airflow from the
air conditioner cools the room air.
This is to remove the smell exuded by the
surroundings.
This is the sound of refrigerant flowing inside the
air conditioner unit.
This is the sound of reversing the freon flow in-
side the unit at the starting and finishing the de-
frosting during Heating operation.
This is to melt the frost which has accumulated on the outdoor
unit (Defrosting Operation). This will take no longer than about
12 minutes, so wait for operation. (Frost accumulates on the
outdoor unit when the outdoor temperature is low and the hu-
midity is high.) Water comes out from the outdoor unit.
Stopfor12minutes.
