WARNING
Ask your dealer or qualified personnel to carry out
installation work. Do not 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 lead to water leakage,
electric shocks or fire.
When a unit is installed in a small room, it is necessary
to take measures so that the leaked refrigerant amount
does not exceed the limit even if it leaks. As for the
measures to prevent the leak from not exceeding the
limit, please consult with your distributor.
If the leaked amount exceeds the limit, it may cause
an oxygen deficiency accident.
Be sure to use only the specified accessories and
parts for installation work.
Failure to use the specified parts may result in water
leakage, electric shocks, fire, or the unit falling.
Install the air conditioner on a foundation that can
withstand its weight.
Insufficient strength may result in the fall of equipment
and causing injury.
Carry out the specified installation work in consideration
of strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due
to fall of equipment.
Make certain that all electrical work is carried out by
qualified personnel according to the local laws and
regulations and this installation manual, using a
separate circuit.
Insufficient capacity of the power supply circuit or
improper electrical construction may lead to electric
shocks or fire.
Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on
the terminal connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units,
and wiring the power supply, form the wires so that
the frontside panel can be securely fastened.
If the frontside panel is not in place, overheat of the
terminals, electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work,
ventilate the area immediately.
Toxic gas may be produced if refrigerant gas comes
into contact with fire.
After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks
into the room and comes into contact with a source of
fire, such as a fan heater, stove or cooker.
Before touching electric terminal parts, turn off power
switch.

CAUTION
Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or water
pipes, lightning conductor or telephone earth
wire.
Incomplete grounding may cause electric
shocks.
Gas pipe.
Ignition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective grounds.
Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a
lightning bolt.
Be sure to install an earth leak detector.
Failure to install an earth leak detector may cause
electric shocks or fire.
Install drain piping according to this installation manual
to ensure good drainage, and insulate the pipe to
prevent condensation.
Improper drain piping may cause water leakage, and
make the furnitures get wet.
Install the indoor and outdoor units, power wire and
connecting wire at least 1 meter away from televisions
or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
Do not rinse the outdoor unit.
This may cause electric shocks or fire.
Do not install the air conditioner in places such as the
following:
Where there is mist of mineral oil, oil spray or vapor
for example a kitchen.
Plastic parts may deteriorate, and cause them to fall
out or water to leak.
Where corrosive gas, such as sulfurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
Where there is machinery
electromagnetic waves.
Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.
Where flammable gases may leak, where carbon
fiber or ignitable dust is suspended in the air or
where volatile flammables, such as thinner or
gasoline, are handled.
Such gases may cause a fire.
Where the air contains high levels of salt such as
that near the ocean.
Where voltage fluctuates a lot, such as that in
factories.
In vehicles or vessels.
Where acidic or alkaline vapoure is present.
Do not allow a child to mount on the outdoor unit or
avoid placing any object on the unit.
Falling or tumbling may result in injury.
Do not touch any refrigerant which has leaked out of
refrigerant piping connections.
This may result in frostbite.
