DANGER
•Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan, heater, stove or cooking device. Exposure to this gas could cause severe injury or death.
•For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
•Any abnormalities in the operation of the air conditioner such as smoke or fire could result in severe injury or death.
Turn off the power and contact your dealer immediately for instructions.
•Do not install the unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death.
•If equipment utilizing a burner is used in the same room as the air conditioner, there is the danger of oxygen deficiency which could lead to an asphyxiation hazard resulting in serious injury or death.
Be sure to ventilate the room sufficiently to avoid this hazard.
•Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children will not play with them. Children playing with plastic bags face the danger of death by suffocation.

WARNING
•It is not good for your health to expose your body to the air flow for a long time.
•Ask your dealer for installation of the air conditioner.
Incomplete installation performed by yourself may result in a water leakage, electric shock, and fire.
•Ask your dealer for improvement, repair, and maintenance.
Incomplete improvement, repair, and maintenance may result in a water leakage, electric shock, and fire.
•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 only to use 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.
•Never let the indoor unit or the remote controller get wet.
It may cause an electric shock or a fire.
•Never use flammable spray such as hair spray, lacquer or paint near the unit.
It may cause a fire.
•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 remove the fan guard of the unit.
A fan rotating at high speed without the fan guard is very dangerous.
•Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work.
•Cut off all electric waves before maintenance.
•To avoid the risk of serious electric shock, never sprinkle or spill water or liquids on the unit.
•Operating the air conditioner with wet hands could result in a shock hazard.
•Do not allow children to play on or around the unit as they could be injured.
•The heat exchanger fins are sharp enough to cut.
To avoid injury, wear gloves or cover the fins while working around them.
•Do not put a finger or other objects into the air inlet or air outlet. The fan is rotating at high speed and will cause injury.
•Do not allow children to play on or around the unit as they could be injured.

•Do not touch the air outlet or horizontal blades while the swing flap is in operation because fingers could get caught and injured.
•Be sure to establish an earth.
Do not earth the unit to a utility pipe, arrester, or telephone earth.
Incomplete earth may cause electrical shock, or fire.
A high surge current from lightning or other sources may cause damage to the air conditioner.
•Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks, or fire.
•Never touch the internal parts of the controller.
Do not remove the front panel because some parts inside are dangerous to touch. In addition, some parts may be damaged to touching. For checking and adjusting internal parts, contact your dealer.
CAUTION
•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.

•Do not touch the air inlet or aluminium fin of the air conditioner.
Otherwise, injury may be caused.
•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.
