Safety 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.

dents 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 condition-•
er such as smoke or fire could result in severe injury or
death. Turn off the power and contact your dealer im-
mediately.
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 mate-•
rials, 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 suffoca-
tion.
WARNING
Contact your dealer for repair and maintenance. Im-•
proper 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 pro-
fessional.
Contact your dealer to move and reinstall the air condi-•
tioner. 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 incor- •
rect 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 mainte-•
nance 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.
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 hu-
midity is above 80% or if the drain outlet gets blocked.

Before cleaning, stop the operation of the unit by turn-•
ing 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 room-•
fumigation 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 hyper-
sensitive 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 chil-•
dren or infirm persons without supervision.
The remote controller should be kept away from chil-•
dren 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 con-•
troller. 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 com-
bustion 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 ben-•
zene, 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
outside 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 drain-
pipe 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.
