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.
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 a ground fault circuit interrupter.●
Failure to install a ground fault circuit interrupter may
result in electric shocks, or fire.
CAUTION
Do not use the air conditioner for any other purposes●
other than comfort cooling or heating. Do not use the
unit for cooling precision instruments, food, plants,
animals or works of art.
Do not place items under the indoor unit as they may●
be damaged by condensates that may form if the
humidity is above 80% or if the drain outlet gets
blocked.
Before cleaning, stop the operation of the unit by●
turning 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.
