CCESSORIES

■

Check if the following accessories are included with the unit

See the figure below for the location of the accessories.

AFETY

CONSIDERATIONS

The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.

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.

■

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, 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, the terminals may overheat
and 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

■

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 indoor unit" or when in "thermostat-stop" operation.

■

Live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.

■

Earth the unit.
Earth 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 earths.

■

Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a lightning
bolt.

■

Be sure to install an earth leakage circuit breaker.
Failure to install an earth leakage circuit breaker may cause
electric shocks and fire.

■

Install drain piping according to this installation manual to
ensure good drainage, and insulate the pipe to prevent
condensation. See combination table in

"General information"

on page 1

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.
