SAFETY CONSIDERATIONS
Read these Safety Considerations for Operations carefully
before installing air conditioner or heat pump. Make sure that
the unit operates properly during the star tup 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.
• 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
or heat pump such as smoke or fire will result in severe
injury or death. Turn off the power and contact your
dealer immediately.
• Refrigerant gas may produce toxic gas if it come into
contact with fire, such as from a fan, heater, stove, or
cooking device. Exposure to this gas will result in severe
injury or death.
• For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen.
A massive leak will result in oxygen depletion, especially
in basements, and an asphyxiation hazard will result
leading to serious injury or death.
• If equipment utilizing a burner is used in the same room
as the air conditioner or heat pump, 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, will
result in stabs or other injuries.
• Tear apart and throw away plastic packaging bags so
that children can not play with them.
Children playing with plastic bags face the danger of
death by suffocation.
• Contact your dealer for repair and maintenance.
Improper repair and maintenance could 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 or heat pump. Incomplete installation could result
in water leakage, electric shock, and fire.
• Never let the indoor unit or the remote controller get wet.
Water could result in an electric shock or a fire.
• Never use flammable spray such as hair spray, lacquer,
or paint near the unit. Flammable spray could result in 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 and
could result in injury.
• 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 could result in 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 could result
in 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 could
result in injury.
• Placing a flower vase or other containers with water or
other liquids on the unit could result in a shock or fire if
a spill occurs.
• Do not touch the air outlet or horizontal blades while the
swing flap is in operation could result in fingers getting
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 ground the unit.
Do not ground the unit to a 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
or heat pump.
• Although this is a recognized measure for additional
protection, with the grounding system in North America,
a dedicated GFCI may not be necessary.

• Do not use the air conditioner or heat pump 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 it coul d result in
damage 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
could result.
• Do not wash the air conditioner or heat pump with
excessive water. An electric shock or fire could result.
• Avoid placing the controller in a spot splashed with
water. Water entering the controller could result in an
electric shock or damage the internal electronic parts.
• Do not operate the air conditioner or heat pump when
using a room fumigation type of insecticide. Failure to
observe this could result in 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 could
result.
• 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 or
heat pump could result in the plastics parts break resulting in water leakage or electric shock.
• Do not touch the air inlet or aluminum fin of the air conditioner or heat pump as they can cut and could result in
injury.
• Do not place objects in direct proximity of the outdoor
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 result in the unit malfunctioning, and could result in
smoke or fire when they make contact with electrical
parts.
• 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 result in the unit malfunctioning.
• 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 result in 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 result in fail to
display the data.
• Do not wipe the controller operation panel with benzene,
thinner, chemical dust cloth, etc. The result may be that
the panel becomes discolored or the coating can peel
off. If it is heavily dirty, soak a cloth in water-diluted neu-
tral 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 or heat pump in a sufficiently
ventilated area and not surrounded by obstacles. Do not
use the air conditioner or heat pump 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 or heat pump yet can suppress the
operating sound and vibration.
b. Places where warm air from the air outlet of the out-
door unit or the operating sound of the outdoor unit
does not annoy neighbors.
• Make sure that there are no obstacles close to the outdoor 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 or heat pump 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 or heat pump is in the cooling
mode, the result may be that the drain pipe becomes
clogged with dust or dirt and water leakage from the
indoor unit may occur. Stop operating the air conditioner
or heat pump and contact your dealer.
