gen. A massive leak can lead to oxygen depletion,
especially in basements, and an asphyxiation hazard
can occur leading to serious injury or death.
• Do not install unit in an area where flammable mate-
rials are present due to risk of explosions that can
cause serious injury or death.
Refrigerant gas may produce toxic gas if it comes in contact
with fire from a fan, heater, stove, cooking device, or other
heat source. Exposure to this gas can cause severe injury
or death.
•Ifequipment utilizing a burner is used in the same
room as the air conditioner, there is the danger of
oxygen deficiency which can lead to an asphyxiation
hazard resulting in serious injury or death.
Be sure to sufficiently ventilate the room to avoid this haz-
ard.
• Any abnormalities in the operation of the air condi-
tioner, such as smoke or fire, can result in severe
injury or death. Turn off the power and contact your
dealer immediately for instructions.

• Do not ground units to water pipes, telephone wires,
or lightning rods because incomplete grounding can
cause a severe shock hazard resulting in severe
injury or death. Do not ground units to gas pipes
because a gas leak can result in an explosion which
could lead to severe injury or death.
• Children playing with plastic bags face the danger of
death by suffocation.
Tear apart and throwaway plastic packaging bags so that chil-
dren cannot play with them. .
WARNING
• Ask your dealer or qualified personnel to carry out
installation work. Do not try to install the machine by
yourself.
Improper installation may result in water leakage, electric
shocks, or fire.
• Perform installation work in accordance with this
installation manual.
Improper installation may result in water leakage, electric
shocks, or fire.
• Be sure to use only the specified accessories and
parts for installation work.
Failure to use the specified parts may result in water leak-
age, electric shocks, fire, or the unit falling.
• Check the unit stand for damage on a continual
basis, especially if it has been used for a long time.
If left in a damaged condition, the unit may fall and cause
injury.
• Do not touch the air outlet or the horizontal louvers
while the swing louver is in operation as fingers may
get caught and injured.
• Carry out the specified installation work after taking
into account strong winds, typhoons, or earth-
quakes.
Improper installation work may result in the equipment fall-
ing and causing accidents.
• Make sure that a separate power supply circuit is
provided for this unit and that all electrical work is
carried out by qualified personnel according to local
laws and regulations, and this installation manual.
An insufficient power supply capacity or improper electrical
construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified
wires are used, and that no external forces act on the
terminal connections or wires.
Improper connections or installation may result in fire.
• When wiring the power supply and connecting the
remote controller wiring and transmission wiring,
position the wires so that the electric parts box lid
can be securely fastened.
Improper positioning of the electric parts box lid may result
in electric shocks, fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• Be sure to establish a ground.
Do not ground the unit to a utility pipe, arrester, or tele-
phone ground.
Incomplete ground may cause electrical shock, or fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
• Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric
shock.
• Be sure to install a ground leakage breaker.
Failure to install a ground leakage breaker may result in
electric shocks, or fire.
• Do not install the air conditioner in the following
locations:
(a) Where a mineral oil mist or oil spray or vapor is pro-
duced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in
water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is
produced.
Corroding copper pipes or soldered parts may result in
refrigerant leakage.
(c) Near machinery emitting electromagnetic waves
Electromagnetic waves may disturb the operation of the
control system and result in a malfunction of the equip-
ment.
• Do not allow children to play on or around the unit as
they could be injured.
• Placing a flower vase or other containers with water
or other liquids can result in a shock hazard or fire if
a spill occurs.
• Do not remove the front panel because some parts
are dangerous to touch. In addition, some parts may
be damaged. For checking and adjusting internal parts,
contact your dealer.
• Do not put a finger or other objects into the air inlet
or air outlet. The fan is rotating at high speed and
