NOTE Symbols:
DANGER .......... Indicates an imminently haz-
ardous situation which, if not
avoided, will result in death or
serious injury.
WARNING ........ Indicates a potentially hazard-
ous situation which, if not
avoided, could result in death
or serious injury.

ty-damage accidents only.
DANGER
Do not install the unit in an area where flam-•
mable 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, could result in severe injury or death.
Turn off the power and contact your dealer
immediately.
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.
Consult your local dealer regarding modifica-•
tion, repair and maintenance of the air condi-
tioner.
Improper workmanship may result in water
leakage, electric shocks or fire hazards.
For refrigerant leakage, consult your dealer.•
Refrigerant gas is heavier than air and re-
places oxygen. A massive leak could lead to
oxygen depletion, especially in basements,
and an asphyxiation hazard could occur lead-
ing 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 deficien-
cy which could lead to an asphyxiation haz-
ard 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.
Do not install the air conditioner at any place•
where there is a danger of flammable gas
leakage.
In the event of a gas leakage, build-up of gas
near the air conditioner may result in fire haz-
ards.
WARNING
Contact your dealer for repair and mainte-•
nance. 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 pro-
fessional.
Contact your dealer to move and reinstall the•
air conditioner or heat pump. Incomplete
installation may result in water leakage, elec-
tric shock, and fire.
Never let the indoor unit or the remote con-•
troller 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. Flam-
mable 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.

stopping operation. Always wait for at least
five minutes before shutting 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 con-•
ditioner or heat pump could make the plas-
tics parts break and cause 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 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.

tions such as a factory or plant
e. Vehicles and vessels
f . A place like a kitchen with a lot of oil and va-
por
g. Where there are machines generating electro-
magnetic waves
h. An 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 autho-•
rized electrician.
To do wiring, ask your dealer. Never do it by
yourself.
Make sure that a separate power supply cir-•
cuit is provided for this air conditioner or
heat pump and that all electrical work is car-
ried out by qualified personnel according to
local laws and regulations.
Pay attention to the installation location
Are the following places selected?•
a. A place that can sufficiently withstand the
weight of the air conditioner or heat pump with
minimal vibration and operation sound.
b. A place where the air discharged from the
outlet of the outdoor unit and the running
sound do not become bothersome.
Are you sure that there are no obstacles near•
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running sound.
If abnormal sounds occur in use, stop the•
operation of the air conditioner or heat pump
and consult your dealer.
Regarding drainage of drain piping
Is the drain piping executed to perform com-•
plete drainage?
If proper drainage is not carried out from the
outdoor drain pipes during air-conditioning op-
eration, chances are that dust and dirt are
clogged in the pipe. This may result in a water
leakage from the indoor unit. Under such circum-
stances, stop the operation of the air conditioner
or heat pump, and then consult your dealer or
our service station.

OPTIMUM OPERATION7.
Observe the following precautions to ensure the
system operates.
Adjust the room temperature properly for a com-•
fortable environment. 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 ventilation of the room.
Keep doors and windows closed. If the doors•
and windows remain open, air will escape and
diminish cooling or heating operation.
Never place objects near the air inlet and the air•
outlet of the unit. It may cause deterioration in
the effect or stop in the 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 elec-
tricity is being used even if the system is not
