2. SAFTY CONSIDERATIONS

Read these “Safety Considerations for Operations” carefully
before installing air conditioning equipment. After completing
the installation, make sure that the unit operates properly during
the startup operation. Instruct the customer on how to operate
and maintain the unit.
Inform customers that they should store this Operation Manual
with the Installation Manual for future reference.
Meanings of DANGER, WARNING, CAUTION, and NOTE Sym­bols:

DANGER........... Indicates an imminently hazardous situa-

tion which, if not avoided, will result in
death or serious injury.

WAR NING ......... Indicates a potentially hazardous situation

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

CAUTION.......... Indicates a potentially 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 situations that may result in

equipment or property-damage accidents
only.

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. Turn off the power and contact your dealer imme­diately.

• Refrigerant gas may produce 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.

• 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.

WAR NING

• Contact your dealer for repair and maintenance.
Improper repair and maintenance may result in water
leakage, electric shock, and fire. Only use accessories
made by Daikin that are specifically designed for use with
the equipment and have them installed by a professional.

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

• Never let the indoor unit or the remote controller get wet.
Water can cause an electric shock or a fire.

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

• When a fuse blows out, never replace it with one of
incorrect ampere ratings or different wires. Always
replace any blown fuse with a fuse of the same specifi­cation.

• 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. Contact a
qualified service person to perform this work.

• Turn off all electrical power before doing any mainte­nance to avoid the risk of serious electric shock; never
sprinkle or spill water or liquids on the unit.

• Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric
shock.

• Do not allow children to play on or around the unit to pre­vent 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.

• Check the unit foundation for damage on a continuous
basis, especially if it has been in use for a long time. If
left in a damaged condition the unit may fall and cause
injury.

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

• Do not touch the air outlet or horizontal blades while the
swing flap is in operation because fingers could get
caught and injured.

• Never touch the internal parts of the controller. Do not
remove the front panel because some parts inside are
dangerous to touch. To check and adjust internal parts,
contact your dealer.

• Be sure to establish a ground.
Do not ground the unit to an utility pipe, arrester, or tele­phone ground. Incomplete grounding 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 a ground fault circuit interrupter.
Failure to install a ground fault circuit interrupter may
result in electric shocks, or fire.
