■ 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.
■ 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 unit 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, hurricanes, 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
legislations 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.
■ Be sure to install an earth leakage circuit breaker in
accordance with the applicable legislations. Failure to do
so may cause electrical shock and 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 the outdoor units
and wiring the power supply, form the wires so that the
panels can be securely fastened.
If the panels are not in place, overheat of the terminals,
electric shocks or a fire may be caused.
■ After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.
■ Never directly touch any accidental leaking refrigerant.
This could result in severe wounds caused by frostbite.
■ Electrical work must be carried out in accordance with
the installation manual and the national electrical wiring
rules or code of practice.
Insufficient capacity or incomplete electrical work may
cause electrical shock or fire.
■ Be sure to use a dedicated power circuit. Never use a
power circuit shared by another appliance.
■ For wiring, use a cable long enough to cover the entire
distance with no connection. Do not use an extension
cord. Do not put other loads on the power supply, use a
dedicated power circuit.
Failure to do so may cause abnormal heat, electric
shock, or fire.
■ Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes may
be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor and other refrigerant cycle parts. Your hands
may suffer burns or frostbite if you touch the refrigerant
pipes. To avoid injury, give the pipes time to return to
normal temperature or, if you must touch them, be sure
to wear proper gloves.

according to the applicable
CAUTION
■
For use of units in applications with temperature alarm
settings it is advised to foresee a delay of 10 minutes
for signalling the alarm in case the alarm temperature
is exceeded. The unit may stop for several minutes
during normal operation for "defrosting of the unit" or
when in "thermostat-stop" operation.
■ Earth the unit.
Earth resistance should be according to the applicable
legislations.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.
- Gas pipe.
Ignition or explosion may occur if the gas leaks.
- Water pipe.
Hard vinyl tubes are not effective earths.
- Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a
lightning bolt.
■ 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 unit. This may cause electric shocks or
fire.
■ Do not install the unit in places such as the following:
- Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall
out or water to leak.
- Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
- Where there is machinery which emits
electromagnetic waves.
Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.
- Where flammable gases may leak, where carbon
fibre 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 vapour is present.
