• Indoor unit quiet operation
When the airflow is set to “ ”, the noise from the indoor unit will become quieter.
Use this when making the noise quieter.
The unit might lose capacity when the airflow rate is set to a weak level.
NOTE
■ Notes on HEAT operation
• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the
heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is
insufficient, it is recommended to use another heating appliance in combination with the air
conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room.
After the start of heating operation, it takes some time before the room gets warmer.
• In heating operation, frost may occur on the outdoor unit and lower the heating capacity. In
that case, the system switches into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of indoor unit.
■ Note on COOL operation
• This air conditioner cools the room by releasing the heat in the room outside.
Therefore, the cooling performance of the air conditioner may be degraded if the outdoor
temperature is high.
■ Note on DRY operation
• The computer chip works to rid the room of humidity while maintaining the temperature as
much as possible. It automatically controls temperature and airflow late, so manual
adjustment of these functions is unavailable.
■ Notes on AUTO operation
• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT)
based on the room and outside temperatures and starts the operation.
• The system automatically reselects setting at a regular interval to bring the room
temperature to user-setting level.
• If you do not like AUTO operation, manually change the set temperature.
■ Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.

TROUBLESHOOTING
Troubleshooting
These cases are not troubles.
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
Case
Explanation
Operation does not start soon. • This is to protect the air conditioner.
• When ON/OFF button was pressed
You should wait for about 3 minutes.
soon after operation was stopped.
• When the mode was reselected.
Hot air does not flow out soon
after the start of HEAT
operation.
• The air conditioner is warming up. You should wait for 1 to 4 minutes.
(The system is designed to start discharging air only after it
has reached a certain temperature.)
The HEAT operation stops suddenly
and a flowing sound is heard.
• The outdoor unit is taking away the frost.
The HEAT operation starts after the frost on the outdoor unit is removed.
You should wait for about 4 to 12 minutes.
A sound is heard.
■ A sound like a flow of water
• This sound is generated because the refrigerant in the air conditioner is flowing.
• This is a pumping sound of the water in the air conditioner
and heard when the water is pumped out from the air
conditioner in cooling or drying operation.
• The refrigerant flows in the air conditioner even if the air conditioner
is not working when the indoor units in other rooms are in operation.
■ Blowing sound
• This sound is generated when the flow of the refrigerant in
the air conditioner is switched over.
■ Ticking sound
• This sound is generated when the size of the air conditioner
slightly expands or shrinks as a result of temperature changes.
■ Clicking sound during operation or idle time
• This sound is generated when the refrigerant control
valves or the electrical parts operate.
■ Clopping sound
• This sound is heard from the inside of the air conditioner
when the exhaust fan is activated while the room doors are
closed. Open the window or turn off the exhaust fan.
The outdoor unit emits water or
steam.
■ In HEAT operation
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
■ In COOL or DRY operation
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
Mist comes out of the indoor
unit.
■ This happens when the air in the room is cooled into mist by
the cold airflow during cooling operation.
■ This is because the air in the room is cooled by the heat
exchanger and becomes mist during defrost operation.
The indoor unit gives out odour. ■ This happens when smells of the room, furniture, or cigarettes
are absorbed into the unit and discharged with the airflow.
(If this happens, we recommend you to have the indoor unit washed by a
technician. Consult the service shop where you bought the air conditioner.)
