Do not use fl ammable spray near the air conditioner, or otherwise fi re may result. •
• Beware of fi re in case of refrigerant leakage. If the air conditioner is not operating correctly, i.e. not generating
cool or warm air, refrigerant leakage could be the cause. Consult your dealer for assistance. The refrigerant
within the air conditioner is safe and normally does not leak.
However, in the event of a leakage, contact with a naked burner, heater or cooker may result in generation of noxious
gas. Do not longer use the air conditioner until a qualifi ed service person confi rms that the leakage has been repaired.
Do not attempt to install or repair the air conditioner yourself. Improper workmanship may result in water leakage, electric •
shocks or fi re hazards. Please contact your local dealer or qualifi ed personnel for installation and maintenance work.
When the air conditioner is malfunctioning (giving off a burning odour, etc.) turn off power to the unit and contact your •
local dealer. Continued operation under such circumstances may result in a failure, electric shocks or fi re hazards.
Be sure to install an earth leakage breaker. Failure to install the earth leakage breaker may result in electric shocks or fi re. •
• Be sure to earth the unit. Do not earth the unit to a utility pipe, lightning conductor or
telephone earth lead. Imperfect earthing may result in electric shocks.
Failure to observe these instructions properly may
result in property damage or personal injury, which
may be serious depending on the circumstances.
Never wet the air conditioner nor the remote
controller with water.
WARNING
CAUTION
• Do not use the air conditioner for purposes other than those for which it is intended. Do not use
the air conditioner for cooling precision instruments, food, plants, animals or works of art as
this may adversely affect the performance, quality and/or longevity of the object concerned.

Preparation before Operation
Turn the breaker on
After the power is turned on, the fl ap of the indoor unit opens and closes once to set the •
reference position.
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 fi lters cause ineffi cient operation and waste energy. Clean them once in about •
every 2 weeks.
Please note
The air conditioner always consumes 15-35W 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, turn the breaker off.
Use the air conditioner in the following conditions. •

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
insuffi cient, 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 HEAT operation, it takes some time before the room gets warmer.
In HEAT 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 fl ow out of indoor unit.•
A pinging sound may be heard during defrosting operation, which, however does not mean •
that the air conditioner has failures.
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 airfl ow rate, 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.
Note on FAN operation
This mode is valid for fan only.•
Note on airfl ow rate setting
At smaller airfl ow rates, the cooling (heating) effect is also smaller.•
The airfl ow rate setting is not variable.

Adjusting the Airfl ow Direction
To adjust the louvers (vertical
blades)
Hold the knob and move the louvers.
(You will fi nd a knob on the left-side and the right-side
blades.)
When the unit is installed in the corner of a room, the •
direction of the louvers should be facing away from the
wall.
If they face the wall, the wall will block off the wind,
causing the cooling (or heating) effi ciency to drop.
CAUTION
Always use a remote controller to adjust the angles of the fl ap. If you attempt to move the fl ap •
and louvers forcibly with hand when they are swinging, the mechanism may be broken.
Be careful when adjusting the louvers. Inside the air outlet, a fan is rotating at a high speed.•
NOTE
Notes on the angles of the fl ap
The fl ap swinging range depends on the •
operation. (See the fi gure.)
If the air conditioner is operated in HEAT •
or DRY operation with the fl ap kept
stopped in the downward direction, the
