About batteries
■■■■
•
When replacing the batteries, use batteries of the same type, and replace the two old batteries
together.
•
When the system is not used for a long time, take the batteries out.
•
We recommend replacing once a year, although if the remote controller display begins to fade or if
reception deteriorates, please replace with new alkali batteries. Using manganese batteries reduces
the lifespan.
•
The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air
conditioner.

procedure.)
NOTE
Tips for saving energy
■■■■
•
Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
•
Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling (heating)
effect.
•
Clogged air filters cause inefficient operation and waste energy. Clean them once in about every two weeks.
Please note
■■■■
•
The air conditioner always consumes 15-35 watts of electricity even while it is not operating.
•
If you are not going to use the air conditioner for a long period, for example in spring or autumn, tur n the breaker
OFF.
•
Use the air conditioner in the following conditions.

Note 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 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 fan strength, so manual adjustment of these functions is unavailable.
Note on AUTO operation
■■■■
•
In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the
room temperature at the start of the operation.
•
The system automatically reselects setting at a regular interval to bring the room temperature to usersetting level.
•
If you do not like AUTO operation, you can manually select the operation mode and setting
you like.
Note on air flow rate setting
■■■■
•
At smaller air flow rates, the cooling (heating) effect is also smaller.

TROUBLE SHOOTING
Trouble Shooting
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.
• When ON/OFF button was
pressed soon after
operation was stopped.
• When the mode was
reselected.
Hot air does not flow out soon
after the start of heating
operation.
The heating operation stops
suddenly and a flowing sound
is heard.
The outdoor unit emits water or
steam.
Mists come out of the indoor
unit.
The indoor unit gives out odour.
The outdoor fan rotates while
the air conditioner is not in
operation.
The operation stopped
suddenly.
(OPERATION lamp is on)
• This is to protect the air conditioner.
You should wait for about 3 minutes.
• 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 system is taking away the frost on the outdoor unit.
You should wait for about 3 to 8 minutes.
■
In HEAT mode
• The frost on the outdoor unit melts into water or steam
when the air conditioner is in defrost operation.
■
In COOL or DRY mode
• Moisture in the air condenses into water on the cool
surface of outdoor unit piping and drips.
■
This happens when the air in the room is cooled into mist by
the cold air flow during cooling operation.
■
This happens when smells of the room, furniture, or
cigarettes are absorbed into the unit and discharged with the
air flow.
(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.)
■
After operation is stopped:
• The outdoor fan continues rotating for another 60
seconds for system protection.
■
While the air conditioner is not in operation:
• When the outdoor temperature is very high, the out door
fan starts rotating for system protection.
■
For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.

An abnormal functioning
happens during operation.
• Hasn’t a breaker turned OFF or a fuse blown?
• Isn’t it a power failure?
• Are batteries set in the remote controller?
• Is the timer setting correct?
• Are the air filters clean?
• Is there anything to block the air inlet or the outlet of the
indoor and the outdoor units?
• Is the temperature setting appropriate?
• Are the windows and doors closed?
• Are the air flow rate and the air direction set appropriately?
• Is the unit set to the INTELLIGENT EYE mode?
(page 16.)
• Are the air filters clean?
• Is there anything to block the air inlet or the outlet of the
indoor and the outdoor units?
Clean the air filters or take all obstacles away and turn the
breaker OFF. Then turn it ON again and try operating the air
conditioner with the remote controller. If the lamp still flashes,
call the service shop where you bought the air conditioner.
• The air conditioner may malfunction with lightening or radio
waves. Turn the breaker OFF, turn it ON again and try
operating the air conditioner with the remote controller.
