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 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, lightening 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

• Do not stand or sit on the outdoor unit. Do not place any object on the unit to avoid injury, do not remove the fan guard.
• Do not place anything under the indoor or outdoor unit that must be kept away from moisture. In certain conditions,
moisture in the air may condense and drip.
• After a long use, check the unit stand and fittings for damage.
• Do not touch the air inlet and aluminum fins of outdoor unit. It may cause injury.
• The appliance is not intended for use by young children or infirm persons without supervision.
• Young children shuld be supervised to ensure that they do not play with the appliance.
• To avoid oxygen deficiency, ventilate the room sufficiently if equipment with burner is used together with the
air conditioner.
• Before cleaning, be sure to stop the operation, turn the breaker off or pull out the supply cord.
• Do not connect the air conditioner to a power supply different from the one as specified. It may cause trouble or fire.
• Depending on the environment, an earth leakage breaker must be installed. Lack of an earth leakage breaker may
result in electric shocks.
• Arrange the drain hose to ensure smooth drainage. Incomplete draining may cause wetting of the building, furniture
etc.
• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around
the unit.
Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunctions, smoke or fire when making contact with electrical parts.
• Do not operate the air conditioner with wet hands.
• Do not wash the indoor unit with excessive water, only use a slightly wet cloth.
• Do not place things such as vessels containing water or anything else on top of the unit. Water may penetrate into the unit and degrade electrical insulations, resulting in an electric shock.
Installation site
■ To install the air conditioner in the following types of environments, consult the dealer.
• Places with an oily ambient or where steam or soot occurs.
• Salty environment such as coastal areas.
• Places where sulfide gas occurs such as hot springs.
• Places where snow may block the outdoor unit.
The drain from the outdoor unit must be discharged to a place of good drainage.
Consider nuisance to your neighbours from noises
■ For installation, choose a place as described below.
• A place solid enough to bear the weight of the unit which does not amplify the operation noise or vibration.
• A place from where the air discharged from the outdoor unit or the operation noise will not annoy
your neighbours.
Electrical work
• For power supply, be sure to use a separate power circuit dedicated to the air conditioner.
System relocation
• Relocating the air conditioner requires specialized knowledge and skills. Please consult the dealer if relocation is necessary for moving or remodeling

ATTENTION
■ 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.

Note for Multi System
〈〈 What is a “Multi System”? 〉〉
This system has one outdoor unit connected to multiple indoor units.
Functions depend on the model. See the list of functions and applicaOutdoor
ble models (*2) on the next page.

■ When the operational capacity is exceeded
The capacity of units that can be connected and the operational capacity of the Inverter Multi A series
are as shown below. If the operational capacity is exceeded, the indoor unit enters Standby Mode,
and the operation light flashed; this is not a malfunction.
<Example>
When the units in rooms A, B, and C are being used, and the D is used, causing an overload:
The room (from A to D) which is closest to the set temperature will go into standby mode. The
room in standby mode will resume operation once operation in the other rooms is stopped.

■ NIGHT QUIET Mode
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.
■ OUTDOOR UNIT SILENT Operation (page 15)
1. With the Priority Room Setting present but inactive or not present
When using the OUTDOOR UNIT SILENT operation feature with the Multi system, set all indoor units to
OUTDOOR UNIT SILENT operation using their remote controllers.
When clearing OUTDOOR UNIT SILENT operation, clear one of the operating indoor units using their remote controller.
However OUTDOOR UNIT SILENT operation display remains on the remote controller for other rooms.
We recommend you release all rooms using their remote controllers.
2. With the Priority Room Setting active
See “Priority Room Setting” on the next page.

■ Priority Room Setting
The Priority Room Setting requires initial programming during installation. Please consult your retailer or
dealer for assistance.
The room designated as the Priority Room takes priority in the following situations;
1. Priority when POWERFUL operation is used
〈Example〉
* Room A is the Priority Room in the examples.
The indoor units in Rooms A,B,C and D are all operating. If the unit in Room A enters POWERFUL
operation, operation capacity will be concentrated in Room A. In such a case, the cooling efficiency of
the units in Rooms B,C and D may be slightly reduced.
2. Priority when using OUTDOOR UNIT SILENT operation
〈Example〉
* Room A is the Priority Room in the examples.
Just by setting the unit in Room A to SILENT operation, the air conditioner starts OUTDOOR UNIT
SILENT operation.
You don’t have to set all the operated indoor units to SILENT operation.
■ Maximum, Power Input Limitation
• The Maximum Power Input Limitation needs to be set when the unit is installed.
Contact DAIKIN dealer.
• This function limits the power input of the unit to 1700W.
It is recommended for locations with low-capacity circuit breakers.

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.
• This is to protect the air conditioner.
You should wait for about 3 minutes.
The outdoor unit emits water or
steam.
■ 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.
