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 come 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.
WARNING
• 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 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.

the power off or by pulling the supply cord out from its
receptacle. Otherwise, an electric shock and injury may
result.
• Do not wash the air conditioner with excessive water. An
electric shock or fire may result.
• Avoid placing the controller in a spot splashed with
water. Water entering the controller may cause an electric shock or damage the internal electronic parts.
• Do not operate the air conditioner when using a roomfumigation type of insecticide. Failure to observe this
could cause the chemicals to be deposited in the unit
and can endanger the health of those who are hypersensitive to chemicals.
• Do not turn off the power immediately after stopping
operation. Always wait for at least five minutes before
turning off the power. Otherwise, water leakage may
occur.
• The appliance is not intended for use by young children
or infirm persons without supervision.
• The remote controller should be kept away from children
so they cannot play with it.
• Consult with the installation contractor for cleaning.
• Incorrect cleaning of the inside of the air conditioner
could make the plastics parts break and cause water
leakage or electric shock.
• Do not touch the air inlet or aluminum fin of the air conditioner as they can cut and cause injury.
• Do not place objects in direct proximity of the outside
unit. Do not let leaves and other debris accumulate
around the unit. Leaves are a hotbed for small animals
which can enter the unit. Once inside the unit, animals
can cause the unit to malfunction, and cause smoke or
fire when they make contact with electrical parts.
NOTE
• 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. It may cause the unit to malfunction.
• Do not place appliances that produce open flames in
places that are exposed to the air flow of the unit or
under the indoor unit. It may cause incomplete combustion or deformation of the unit due to the heat.
• Do not expose the controller to direct sunlight. The LCD
display can become discolored and may fail to display
the data.
• Do not wipe the controller operation panel with benzene,
thinner, chemical dust cloth, etc. The panel may get discolored or the coating can peel off. If it is heavily dirty,
soak a cloth in water-diluted neutral detergent, squeeze
it well and wipe the panel clean. Then wipe it with
another dry cloth.
• Dismantling of the unit, disposal of the refrigerant, oil,
and additional parts, should be done in accordance with
the relevant local, state, and national regulations.
• Operate the air conditioner in a sufficiently ventilated
area and not surrounded by obstacles. Do not use the air
conditioner in the following places.
a. Places with a mist of mineral oil, such as cutting oil.
b. Locations such as coastal areas where there is a lot of
salt in the air.
c. Locations such as hot springs where there is a lot of
sulfur in the air.
d. Locations such as factories where the power voltage
varies a lot.
e. In cars, boats, and other vehicles.
f. Locations such as kitchens where oil may splatter or
where there is steam in the air.
g. Locations where equipment produces electromag-
netic waves.
h. Places with an acid or alkaline mist.
i. Places where fallen leaves can accumulate or where
weeds can grow.
• Take snow protection measures. Contact your dealer for
the details of snow protection measures, such as the
use of a snow protection hood.
• Do not attempt to do electrical work or grounding work
unless you are licensed to do so. Consult with your
dealer for electrical work and grounding work.
• Pay Attention to Operating Sound. Be sure to use the following places:
a. Places that can sufficiently withstand the weight of
the air conditioner yet can suppress the operating
sound and vibration of the air conditioner.
b. Places where warm air from the air outlet of the out-
side unit or the operating sound of the outside unit
does not annoy neighbors.
• Make sure that there are no obstacles close to the outside unit. Obstacles close to the outside unit may drop
the performance of the outside unit or increase the operating sound of the outside unit.
• Consult your dealer if the air conditioner in operation
generates unusual noise.
• Make sure that the drainpipe is installed properly to
drain water. If no water is discharged from the drainpipe
while the air conditioner is in the cooling mode, the
drainpipe may be clogged with dust or dirt and water
leakage from the indoor unit may occur. Stop operating
the air conditioner and contact your dealer.
