READ BEFORE OPERATION
Safety precautions
• Keep th is manual where the operator can easily find them.
• Read this manual attentively before starting up the unit.
• For safety reason the operator must read the following cautions carefully.
• This manual classifies precautions into WARNINGS and CAUTIONS. Be sure to follow all precau-
tions below: they are all important
for ensuring safety.
WARNING
• In order to avoid fire, explosion or injury, do not operate the unit when harmful, among which flammable or
corrosive gases, are detected near the unit.
• It is not good for health to expose your body to the air flow for a long time.
• Do not put a finger, a rod or other objects into the air outlet or inlet. As the fan is rotating at a high speed, it will
cause injury.
• Do not attempt to repair, relocate, modify or reinstall the air conditioner by yourself. Incorrect work will cause electric
shocks, fire etc.
For repairs and reinstallation, consult your Daikin dealer for advice and information.
• The refrigerant used in the air conditioner is safe. Although leaks should not occur, if for some
reason any refrigerant happens to leak into the room, make sure it does not come in contact
with any flame as of gas heaters, kerosene heaters or gas range.
• If the air conditioner is not cooling (heating) properly, the refrigerant may be leaking, so call your dealer.
When carrying out repairs accompanying adding refrigerant, check the content of the repairs with our service staff.
• Do not attempt to install the air conditioner by your self. Incorrect work will result in water leakage, electric shocks or
fire. For installation, consult the dealer or a qualified technician.
• In order to avoid electric shock, fire or injury, if you detect any abnormally such as smell of fire, stop the operation and
turn off the breaker. And call your dealer for instructions.
CAUTION
• The air conditioner must be earthed. Incomplete earthing may result in electric shocks. Do not connect the
earth line to a gas pipe, water pipe, lightning rod, or a telephone earth line.
• In order to avoid any quality deterioration, do not use the unit for cooling precision instruments, food, plants,
animals or works of art.
• Never expose little children, plants or animals directly to the air flow.
• Do not place appliances which produce open fire in places exposed to the air flow from the unit or under the
indoor unit. It may cause incomplete combustion or deformation of the unit due to the heat.
• Do not block air inlets nor outlets. Impaired air flow may result in insufficient performance or trouble.

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.

■
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, turn the breaker OFF.
• Use the air conditioner in the following conditions.
• Operation outside this humidity or temperature range may cause a safety device to disable the system.

■
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 rec-
ommended 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 adjust-
ment 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 user-
setting 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
The following cases are not air conditioner troubles but have some reasons. You may just continue using it.
These cases are not troubles.
Case Explanation
Operation does not start soon.
•When ON/OFF button was
pressed soon after
operation was stopped.
•When the mode was
reselected.
•This is to protect the air conditioner.
You should wait for about 3 minutes.
Hot air does not flow out soon
after the start of heating
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 heating operation stops
suddenly and a flowing sound
is heard.
•The system is taking away the frost on the outdoor unit.
You should wait for about 3 to 8 minutes.
The outdoor unit emits water or
steam.
■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.
Mists come out of the indoor
unit.
■This happens when the air in the room is cooled into mist by
the cold air flow during cooling 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
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.)
The outdoor fan rotates while
the air conditioner is not in
operation.
■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.
The operation stopped
suddenly.
(OPERATION lamp is on)
■For system protection, the air conditioner may stop
operating on a sudden large voltage fluctuation.
It automatically resumes operation in about 3 minutes.
