Installation

and operation manual

The safety considerations listed here are divided into the following
types and cover very important topics, so be sure to follow them
carefully.

DANGER

Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.

WARNING

Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.

CAUTION

Indicates a potentiality hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices.

NOTE

Indicates situation that may result in equipment or
property-damage-only accidents.

Keep these warning sheets handy so that you can refer to them
when needed.

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

READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION. KEEP THIS MANUAL IN A HANDY
PLACE FOR FUTURE REFERENCE.

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.

IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DAIKIN DEALER FOR
ADVICE AND INFORMATION.

S

AFETY

Please read these safety precautions carefully before installing the
air conditioning equipment and be sure to install it correctly. After
completing the installation, make sure that the unit operates properly
during the start-up operation. Please instruct the customer on how to
operate the unit and keep it maintained.

Inform customers that they should store this operation manual along
with the installation manual for future reference. This air conditioner
comes under the term "appliances not accessible to the general
public".

CONSIDERATIONS

DANGER

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.

Tu rn off the power and contact your dealer
immediately for instructions.

■

If refrigerant gas comes in contact with fire such
as from a fan, heater, stove or cooking device, it
may produce toxic gases. Exposure to these
gases could cause severe injury or death.

■

If there is a 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 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 can not play with them. Children playing
with plastic bags face the danger of death by
suffocation.

rating or wires when a fuse is blown.

Not replacing a blown fuse by a fuse of correct
ampere rating 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 an authorized service person to perform this
work.

■

Cut off all electric waves before maintenance.

■

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

Placing a flower vase or other containers with water or
other liquids on the unit could result in a shock hazard
or fire if a spill occurs.

■

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.

■

Check the unit stand for damage on a continuous
basis.

If left in a damaged condition the unit may fall and
cause injury.

■

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 touch the air outlet or the horizontal flaps
while the swing flap is in operation as fingers may
get caught and injured.

■

Be sure to install an earth leakage breaker.
