English
Improper drain piping may cause water leakage, make the
furniture get wet.
• Install the air conditioner, power supply wiring, remote con-
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 light-
ing type (inverter or rapid start type) fluorescent lamp is
installed.
• Do not install the air conditioner in places such as the follow-
ing:
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 condi-
tioner, it may cause ignition.
• The air conditioner is not intended for use in a potentially
explosive atmosphere.

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 reach-
ing 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.
• 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.
(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 electro-
magnetic interference.

PRECAUTIONS
• Be sure to read this manual before installing the indoor unit.
• Entrust installation to the place of purchase or a qualified ser-
viceman. 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.
