situation which, if not avoided,
could result in death or serious
injury.

CAUTION.... Indicates a potentially hazardous

situation which, if not avoided,

Keep these warning sheets handy so that you

Also, if this equipment is transferred to a new user,
make sure to hand over this operation manual to the
new user.

• Do not install the unit in an area where flam­mable materials are present due to risk of
explosion resulting in 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.

• Refrigerant gas may product toxic gas if it
comes in contact with fire such a 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.

• 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.

• 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 power supply before main­tenance.

• To avoid the risk of serious electrical shock,
never sprinkle or spill water or liquids on the
unit.

• 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.

• Operating the air conditioner with wet hands
could result in a shock hazard.
