ant leakage, electrical shock, fire, or explosion.
Meanings of DANGER, WARNING, CAUTION and NOTE
Symbols:
DANGER...............Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING.............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.
•Any abnormalities in the operation of the heat pump
such as smoke of 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
contract 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. Refrig-
erant 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 heat pump, there is the danger of oxy-
gen deficiency which could lead to an asphyxiation
hazard resulting in serious injury or death. Be sure
to ventilate the room sufficiently to avoid this haz-
ard.
• Safely dispose of the packing materials. Packing ma-
terials,suchas nails and othermetalorwooden parts,
may cause stabs or other injuries.
• Tear apart and throw away plastic packaging bags
sothatchildrenwill not play withthem. Childrenplay-
ing with plastic bags face the danger of death by suf-
focation.
•Contact your dealer for repair and maintenance. Im-
proper repair and maintenance may result in water
leakage, electric shock and fire. Only use accesso-
ries made by Daikin that are specifically designed for
use with this equipment and have them installed by
a professional.
• Contact your dealer to move and reinstall the heat
pump. 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, lac-
quer or paint near the unit. Flammable spray may
cause a fire.
• Never remove the front panel of the unit. A fan rotating at
high speed without the front panel is very dangerous.
• Never inspect or service the unit by yourself. Con-
tact a qualified service person to perform this work.
• Turn off all electrical power before doing any main-
tenance 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 work-
ing 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 continu-
ous basis, especially if it has been in use for a long
time. If left in a damaged condition the unit may 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.
• Never touch the internal parts of the controller. Do
not remove the front panel because some parts in-
side are dangerous to touch. To check and adjust
internal parts, contact your dealer.
• Do not use the 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 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 heat pump 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
electricshockordamage the internal electronicparts.
• Do not operate the heat pump 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.
• 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 heat pump
could make the plastic parts break and cause water
leakage or electric shock.
• Do not touch the air inlet or aluminum fin of the heat
pump as they can cut and cause injury.
• Do not place objects in direct proximity of the out-
side unit. Do not let leaves and other debris accumu-
late 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.
• 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 accor-
dancewiththerelevant local, state, andnationalregu-
lations.
• Operatetheheatpump in a sufficientlyventilatedarea
and not surrounded by obstacles. Do not use the 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 volt-
age varies a lot.

e. In cars, boats, and other vehicles.
f. Locations such as kitchens where oil may splat-
ter or where there is steam in the air.
g. Locations where equipmentproduceselectromag-
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.
• Pay attention to operating sound. Be sure to use the
following places:
a. Places that can sufficiently withstand the weight
of the heat pump yet can suppress the operat-
ing sound and vibration of the heat pump.
b. Places where warm air from the air outlet of the
outside unit or the operating sound of the out-
side unit does not annoy neighbors.
• Consultyourdealerif the heat pumpinoperation gen-
erates unusual noise.
• Make sure that the drainpipe is installed properly to
drain water. If no water is discharged from the drain-
pipe while the heat pump is in the cooling mode, the
drainpipe may be clogged with dust or dirt and water
leakage from the indoor unit may occur. Stop oper-
ating the heat pump and contact your dealer.

AIR HANDLER
AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer.
REPLACE OR CLEAN FILTER
IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency,
equipment damage and possible fire.
Anindoorairfiltermustbeusedwithyourcomfortsystem.Aproperlymaintainedfilterwillkeeptheindoorcoilofyourcomfortsystemclean.
A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air
conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced.
Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types.
These filters can do a better job of catching small airborne particles.
MOTORS
Indoor and outdoor fan motors are permanently lubricated and do
not require additional oiling.
