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.
•
Depending on the environment, an earth leakage breaker must be installed. Lack of an earth leakage breaker may
result in electric shocks or fire.
•

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.
•
The batteries will last for approximately one year. If the remote controller display begins to fade and
the degradation of reception performance occurs within a year, however, replace both two batteries
with new size AAA alkaline batteries.
•
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.

Preparation Before Operation
■ To operate the remote
controller
• To use the remote controller, aim the transmitter
at the indoor unit. If there is anything to block
signals between the unit and the remote controller, such as a curtain, the unit will not operate.
•
Do not drop the remote controller. Do not get it wet.
• The maximum distance for communication is
about 7m.
■ To fix the remote controller

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, turn the breaker OFF.
• Use the air conditioner in the following conditions.

NOTE
■
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 COOL operation
• This air conditioner cools the room by blowing the hot air in the room outside, so if the
outside temperature is high, the performance of the air conditioner drops.
■
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 rate, 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, manually change the set temperature.

What is a “Multi System”?
This system has one outdoor unit connected to multiple indoor units.
■
Selecting the Operation Mode
1. With the Priority Room Setting
present but inactive or not present.
When more than one indoor unit is operating, priority is
given to the first unit that was turned on.
In this case, set the units that are turned on later to the
same operation mode (*1) as the first unit.
Otherwise, they will enter the Standby Mode, and the operation lamp will flash; this does not indicate malfunction.
(*1)
•
COOL, DRY and FAN mode may be used at the same time.
•
AUTO mode automatically selects COOL mode or HEAT mode based on the room temperature.
Therefore, AUTO mode is available when selecting the same operation mode as that of the room
with the first unit to be turned on.
〈
CAUTION
Normally, the operation mode in the room where the unit is first run is given priority, but the following situations are
exceptions, so please keep this in mind.
If the operation mode of the first room is FAN Mode, then using Heating Mode in any room after this will give priority to
heating. In this situation, the air conditioner running in FAN Mode will go on standby, and the operation lamp will flash.
2.
With the Priority Room Setting active.
See “Priority Room Setting” on the next page.
■
NIGHT QUIET Mode (Available only for cooling operation)
NIGHT QUIET Mode requires initial programming during installation. Please consult your retailer or dealer for assistance.
NIGHT QUIET Mode reduces the operation noise of the outdoor unit during the night time hours to prevent
annoyance to neighbors.
•
The NIGHT QUIET Mode is activated when the temperature drops 5°C or more below the highest temperature
recorded that day. Therefore, when the temperature difference is less than 5°C, this function will not be activated.
•
NIGHT QUIET Mode reduces slightly the cooling efficiency of the unit.

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.
Mist comes 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.)
No remote controller signals are displayed.
The remote controller sensitivity is low.
The display is low in contrast or
blacked out.
The display runs out of control.
• 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 airflow during cooling operation.
■ 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.)
■ 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.
• The batteries are dying and the remote controller is malfunctioning. Replace all the batteries with new size AAA alkaline
batteries. For details, refer to “To set the batteries” of this
manual. (page7.)
* If the reset button is provided, press the reset button after the
batteries are replaced.
