CAUTION

• 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.

• Install the air conditioner, power supply wiring, remote

controller 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

produced.
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.

2. BEFORE INSTALLATION

•

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 moving the unit at or after opening, hold the unit by the

hanger brackets (× 4). Do not apply force to the refrigerant
piping, drain piping or plastic parts.

• 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.
(Copper tubing and brazed spots may corrode which
could eventually lead to refrigerant leaks.)

•

Where exposed to combustible gases and where
volatile flammable gas like thinner or gasoline is
used. (Gas in the vicinity of the unit could ignite.)

•

Where machines can generate electromagnetic
waves. (Control system may malfunction.)

•

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.

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 or 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.

• Be sure to mount an air filter (part to be procured in the field)

in the suction air passage in order to prevent water leaking,
etc.
