Safety considerations
Please read these “Safety considerations” carefully
before installing 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.
Also, 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”.
Meaning of danger, warning, caution and note symbols.
DANGER ....... Indicates an imminently haz-
ardous situation which, if not
avoided, will result in death or
serious injury.
WARNING ..... Indicates a potentially hazard-
ous situation which, if not
avoided, could result in death
or serious injury.
Keep these warning sheets handy so that you
can refer to them if needed.
Also, if this equipment is transferred to a new user,
make sure to hand over this operation manual to
the new user.
• 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.
NOTE..............Indicates situation that may
result in equipment or propertydamage-only accidents.
CAUTION ...... Indicates a potentially hazard-
ous situation which, if not
avoided, may result in minor or
moderate injury. It may also be
sued to alert against unsafe
practices.

• 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.
• The heat exchanger fins are sharp enough to
cut.
To avoid injury, wear gloves or cover the fins while

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.

children or infirm persons without supervision.
• The remote controller should be installed in
such away that children cannot play with it.
• Consult with installation contractor for cleaning the inside of the air conditioner.
Wrong cleaning may make the plastics parts broken or cause failure of water leakage or electric
shock.
• 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.
• 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.
