1. SAFETY PRECAUTIONS

Be sure to follow this “SAFETY PRECAUTIONS”.
This product comes under the term “appliances not accessible
to the general public”.
This is a class A product. In a domestic environment this prod­uct may cause radio interference in which case the user may be
required to take adequate measures.

This manual classifies the precautions into WARNINGS and
CAUTIONS.
Be sure to follow all the precautions below: They are all impor­tant for ensuring safety.

WARNING ............. Indicates a potentially hazardous situ-

ation which, if not avoided, could result
in death or serious injury.

CAUTION .............. Indicates a potentially hazardous situ-

ation which, if not avoided, may result
in minor or moderate injury.
It may also be used to alert against
unsafe practices.

• After the installation is completed, test the air conditioner and
check if the air conditioner operates properly. Give the user
adequate instructions concerning the use and cleaning of the
indoor unit according to the Operation Manual. Ask the user
to keep this manual and the Operation Manual together in a
handy place for future reference.

•

Ask your local dealer or qualified personnel to carry out
installation work.
Improper installation may result in water leakage, electric
shocks or a fire.

• Perform installation work in accordance with this installation
manual.
Improper installation may result in water leakage, electric
shocks or a fire.

• Consult your local dealer regarding what to do in case of
refrigerant leakage.
When the air conditioner is installed in a small room, it is nec­essary to take proper measures so that the amount of any
leaked refrigerant does not exceed the concentration limit in
the event of a leakage.

Otherwise, this may lead to an accident due to oxygen defi­ciency.

• Be sure to use only the specified parts and accessories for
installation work.
Failure to use the specified parts may result in the air condi­tioner falling down, water leakage, electric shocks, a fire, etc.

• Install the air conditioner on a foundation that can withstand
its mass.
Insufficient strength may result in the air conditioner falling
down and causing injury.
In addition, it may lead to vibration of indoor units and cause
unpleasant chattering noise.

• Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes. Improper installa­tion may result in an accident such as air conditioner falling.

• Make certain that all electrical work is carried out by qualified
personnel according to the applicable legislation (note 1) and
this installation manual, using a separate circuit.
In addition, even if the wiring is short, make sure to use a wir­ing that has sufficient length and never connect additional
wiring to make the length sufficient.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or a fire.
(note 1) applicable legislation means “All international,

national and local directives, laws, regulations and/
or codes which are relevant and applicable for a
certain product or domain”.

• Make sure that all wiring is secure, using the specified wiring
and ensuring that external forces do not act on the terminal
connections or wiring.
Incomplete connection or fixing may cause an overheat or a fire.

• When wiring the remote controller wiring and transmission
wiring, and wiring the power supply, form the wiring orderly
so that the control box cover can be securely fastened.
If the control box cover 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 a 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 a fire, such as a
fan heater, stove or cooker.

• Disconnect the power supply before touching the electric
components.
If you touch the live part, you may get an electric shocks.

• Earth the air conditioner.
Do not connect the earth wiring to gas or water piping, light­ning conductor or telephone earth wiring.
Incomplete earthing may cause electric shocks or a fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.

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

• Install drain piping according to this installation manual to
ensure good drainage, and insulate the piping to prevent
condensation.
Improper drain piping may cause water leakage, make the
furniture get wet.

English 1

• Install the air conditioner, power supply wiring, remote con-

4 screws

troller wiring and transmission wiring 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.)

• Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic light­ing type (inverter or rapid start type) fluorescent lamp is
installed.

• Do not install the air conditioner in places such as the follow­ing:

1. Where there is mist of oil, oil spray or vapour for example

a kitchen.
Resin parts may deteriorate, and cause them to fall out or
water to leak.

2. Where corrosive gas, such as sulfurous acid gas, is pro-

duced.
Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.

3. Where there is machinery which emits electromagnetic

waves.
Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.

4. 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.
If the gas should leak and remained around the air condi­tioner, it may cause ignition.

• The air conditioner is not intended for use in a potentially
explosive atmosphere.

• Where the air contains high levels of salt such as that

near the ocean and where voltage fluctuates greatly
such as that in factories. Also in vehicles or vessels.

• This unit, both indoor and outdoor, is suitable for installation
in a commercial and light industrial environment.
If installed as a household appliance it could cause electro­magnetic interference.

2-1 PRECAUTIONS

• Be sure to read this manual before installing the indoor unit.

• Entrust installation to the place of purchase or a qualified ser­viceman. Improper installation could lead to leaks and, in
worse cases, electric shock of fire.

• Use only parts provided with the unit or parts satisfying
required specifications. Unspecified parts could cause the
unit to fall out of place, or could lead to leaks and, in worse
cases, electric shock or fire.

When moving the unit while removing it from the carton
box, be sure to lift it by holding on to the four lifting lugs
without exerting any pressure on other parts, especially,
the refrigerant piping, drain piping, and other resin parts.

• Be sure to check the type of R410A refrigerant to be used
before installing the unit.(Using an incorrect refrigerant will
prevent normal operation of the unit.)

• The accessories needed for installation must be retained in
your custody until the installation work is completed. Do not
discard them!

• Decide upon a line of transport.

• Leave the unit inside its packaging while moving, until reach­ing the installation site. Where unpacking is unavoidable, use
a sling of soft material or protective plates together with a
rope when lifting, to avoid damage or scratches to the unit.

• When selecting installation site, refer to the paper pattern.

• For the installation of an outdoor unit, refer to the installation
manual attached to the outdoor unit.

• Do not install or operate the unit in rooms mentioned below.

• Laden with mineral oil, or filled with oil vapor or spray

like in kitchens. (Plastic parts may deteriorate which
could eventually cause the unit to fall out of place, or
could lead to leaks.)

• Where corrosive gas like sulfurous gas exists. (Cop-

per tubing and brazed spots may corrode which could
eventually lead to refrigerant leaks.)

• Where exposed to combustible gases and where vol-

atile flammable gas like thinner or gasoline is used.
