DANGER
• Do not install the unit in an area where flammable mate-
rials 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 imme-
diately.
• Refrigerant gas may produce toxic gas if it comes in con-
tact with fire, such as from a fan, heater, stove, or cook-
ing 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, espe-
cially 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 defi-
ciency 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 materi-
als, 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 profes-
sional.
• Contact your dealer to move and reinstall the air condi-
tioner. Incomplete installation may result in water leak-
age, 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 specifi-
cation.
• 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 pre-
vent 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 may cause
injury.
• Check the unit foundation for damage on a regular 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 control box cover because some parts inside
are dangerous to touch. To check and adjust internal
parts, contact your dealer.
• Be sure to ground the unit.
Do not ground the unit to a utility pipe, arrester, or tele-
phone ground. Incomplete grounding may cause electric
shock, or fire. A high surge current from lightning or
other sources may cause damage to the air conditioner.
• This equipment can be installed with a Ground-Fault Cir-
cuit Interrupter (GFCI). Although this is a recognized
measure for additional protection, with the grounding
system in North America, a dedicated GFCI is not neces-
sary.
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, ani-
mals 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, turn the unit off and disengage power.
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 where it can be
splashed with water. Water entering the controller may
cause an electric shock or damage the internal elec-
tronic 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 hypersen-
sitive 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 con-
ditioner as they can cut and cause injury.
NOTE
• Never press the button of the remote controller with a
hard, pointed object. The remote controller may be dam-
aged.
• Never pull or twist the electric wire of the remote control-
ler. It may cause the unit to malfunction.
• Do not place appliances that produce open flames in
places that are exposed to the airflow 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 dis-
colored 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.
• 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.
• Make sure that there are no obstacles close to the out-
door unit. Obstacles close to the outdoor unit may drop
the performance of the outdoor unit or increase the
operating sound of the outdoor 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.

Regarding places for installation
• Is the air conditioner installed at a well-ventilated place
where there are no obstacles around?
• Do not use the air conditioner in the following places.
a. Filled with much mineral oil such as cutting oil
b. Where there is much salt such as a beach area
c. Where sulfuric gas exists such as a hot-spring resort
d. Where there are considerable voltage fluctuations such as
a factory or plant
e. Vehicles and vessels
f. Where there is oil splatter and vapor such as a kitchen,
etc.
g. Where there are machines generating electromagnetic
waves
h. Areas filled with acid and/or alkaline steam or vapor
• Is a snow protection measure taken?
For details, consult your dealer.
Regarding wiring
• All wiring must be performed by an authorized electri-
cian.
To do wiring, ask your dealer. Never do it by yourself.
• Make sure that a separate power supply circuit is pro-
vided for this air conditioner and that all electrical work
is carried out by qualified personnel according to local
laws and regulations.
Pay attention to noise during operation, too
• Are the following places selected?
a. A place that can sufficiently withstand the weight of the air
conditioner with less noise while running and vibrations.
b. A place where the airflow and noise generated from the air
outlet by the outdoor unit is not a nuisance to the neigh-
borhood.
• Are you sure that there are no obstacles near the air out-
let of the outdoor unit?
Such obstacles may result in declined performance and
increased running noises.
• If abnormal noise occurs while in use, consult your
dealer.
Regarding drainage of drain piping
• Is the drain pipe able to perform complete drainage?
If proper drainage is not carried out from the outdoor drain
pipes during cooling operation, chances are that dust and dirt
are clogged in the pipe. This may result in water leakage from
the indoor unit. Under such circumstances, stop the opera-
tion of the air conditioner, and then consult your dealer or our
service station.
Read the operation manual that came with the
remote controller.
• Operating procedure varies with heat pump type and cooling
only type. Contact your Daikin dealer to confirm your system
type.
• To protect the unit, turn on the main power switch 6 hours
before operation.
• If the main power supply is turned off during operation, oper-
ation will restart automatically after the power turns back on
again.
Observe the following precautions to ensure the system oper-
ates.
• Adjust the room temperature properly for a comfortable envi-
ronment. Avoid excessive heating or cooling.
• Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.
• Ventilate the room regularly.
Using the unit for long periods of time requires attentive ven-
tilation of the room.
• Keep doors and windows closed. If the doors and windows
remain open, room air will escape and diminish performance
of cooling and heating operation.
• Do not place other heaters directly below the indoor unit.
They may deform due to the heat.
• Do not block the air inlet or air outlet of the unit as it will cause
a decrease in performance or stop operation.
• Turn off the main power supply switch when it is not used for
long periods of time. When the main power switch is turned
on, some watts of electricity is being used even if the system
is not operating. Turn off the main power supply switch for
saving energy. When reoperating, turn on the main power
supply switch 6 hours before operation for smooth running
(Refer to MAINTENANCE).
• When the display shows “Time to clean filter” ask a qualified
service person to clean the filter (Refer to MAINTENANCE).
• It takes time for the room temperature to reach the set tem-
perature.
We recommend starting the operation in advance using timer
operation.
