Warnings

It is not good for your health to expose your body to the air flow
for a long time.

In order to avoid electric shock, fire or injury, or if you detect any
abnormality such as smell of fire, turn off the power supply and
call your dealer for instructions.

Ask your dealer for installation of the air conditioner.
Incomplete installation performed by yourself may result in a
water leakage, electric shock, and fire.

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.

Ask your dealer for improvement, repair, and maintenance.
Incomplete improvement, repair, and maintenance may result in
a water leakage, electric shock and fire.

Do not insert fingers, rods or other objects into the air inlet or
outlet. When the fan is rotating at high speed, it will cause injury.

Never let the indoor unit or the remote controller get wet.
It may cause an electric shock or a fire.

Never use a flammable spray such as hair spray, lacquer or paint
near the unit.
It may cause a fire.

Never touch the air outlet or the horizontal blades while the
swing flap is in operation.
Fingers may become caught or the unit may break down.

Never replace a fuse with that of wrong ampere ratings or other
wires when a fuse blows out.
Use of wire or copper wire may cause the unit to break down or
cause a fire.

Never put any objects into the air inlet or outlet.
Objects touching the fan at high operating speed can be
dangerous.

Never press the button of the remote controller with a hard,
pointed object.
The remote controller may be damaged.

Never pull or twist the electric wire of the remote controller.
It may cause the unit to malfunction.

Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work.

To prevent refrigerant leak, contact your dealer.
When the system is installed and runs in a small room, it is
required to keep the concentration of the refrigerant, if by any
chance coming out, below the limit. Otherwise, oxygen in the
room may be affected, resulting in a serious accident.

The refrigerant in the air conditioner is safe and normally does
not leak. If the refrigerant leaks in the room, contact with a fire of
a burner, a heater or a cooker may result in a harmful gas.
Tu rn off any combustible heating devices, ventilate the room and
contact the dealer where you purchased the unit.
Do not use the air conditioner until a service person confirms
that the portion where the refrigerant leaks is repaired.

Improper installation or attachment of equipment or accessories
could result in electric shock, short-circuit, leaks, fire or other
damage to the equipment. Be sure to use only accessories
made by Daikin which are specifically designed for use with the
equipment and have them installed by a professional.

Ask your dealer to move and reinstall the air conditioner.
Incomplete installation may result in a water leakage, electric
shock, and fire.

Consult the dealer if the air conditioner submerges owing to a
natural disaster, such as a flood or typhoon.
Do not operate the air conditioner in that case, or otherwise a
malfunction, electric shock, or fire may result.

Do not start or stop operating the air conditioner with the power
supply breaker turned ON or OFF.
Otherwise, fire or water leakage may result. Furthermore, the
fan will rotate abruptly if power failure compensation is enabled,
which may result in injury.

Do not use the product in the atmosphere contamined with oil
vapor, such as cooking oil or machine oil vapor.
Oil vapor may cause crack damage, electric shocks, or fire.

Be sure to use a dedicated power supply for the air conditioner.
The use of any other power supply may cause heat generation,
fire or product failures.

Cautions

Do not use the air conditioner for other purposes.
In order to avoid any quality deterioration, do not use the unit for
cooling precision instruments, food, plants, animals or works of
art.

In order to avoid injury, do not remove the fan guard of the
outdoor unit.

To avoid oxygen deficiency, ventilate the room sufficiently if
equipment with burner is used together with the air conditioner.

After a long use, check the unit stand and fitting for damage.
If damaged, the unit may fall and result in injury.

Do not place a flammable spray bottle near the air conditioner
and do not use sprays.
Doing so may result in a fire.

■

Before cleaning, be sure to stop the operation, turn the breaker
off or pull out the supply cord.
Otherwise, an electric shock and injury may result.

■

Do not operate the air conditioner with a wet hand.
An electric shock may result.

■

Do not place items which might be damaged by moisture under
the indoor unit.
Condensation may form if the humidity is above 80%, if the drain
outlet is blocked or the filter is polluted.

■

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 allow anyone to mount on the outdoor unit or avoid
placing any object on it.
Falling or tumbling may result in injury.

■

Adverse influence to little children, animals and plants may
result.

■

Do not wash the air conditioner with water.
Electric shock or fire may result.

■

Do not install the air conditioner at any place where flammable
gas may leak out.
If the gas leaks out and stays around the air conditioner, a fire
may break out.

■

In order to avoid electric shock or fire, make sure that an earth
leak detector is installed.

■

Be sure the air conditioner is electrically earthed.
In order to avoid electric shock, make sure that the unit is
grounded and that the earth wire is not connected to gas or
water pipe, lightning conductor or telephone earth wire.

■

Arrange the drain hose to ensure smooth drainage. Incomplete
drainage may cause wetting of the building, furniture etc.

■

Do not let children play on and around the outdoor unit.
If they touch the unit carelessly, it may result in injury.

The LCD display may get discolored, failing to display the data.

■

Do not wipe the controller operation panel with benzine, thinner,
chemical dustcloth, etc.
The panel may get discolored or the coating peeled off. If it is
heavily dirty, soak a cloth in water-diluted neutral detergent,

dry cloth.

■

Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are dangerous
to touch and a machine trouble may happen. For checking and
adjusting the internal parts, contact your dealer.

■

Avoid placing the controller in a spot splashed with water.
Water coming inside the machine may cause an electric leak or
may damage the internal electronic parts.

■

Do not operate the air conditioner when using a room fumigation

- type insecticide.
Failure to observe could cause the chemicals to become
deposited in the unit, which could endanger the health of those
who are hypersensitive to chemicals.

These fins are sharp and could result in cutting injuries.

■

The appliance is not intended for use by young children or infirm
persons without supervision.

■

Young children should be supervised to ensure that they do not
play with the appliance.

■

Do not block air inlets nor outlets.
Impaired air flow may result in insufficient performance or
