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, flanges 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 or affter opening, hold the unit by the
hanger brackets (× 4). Do not apply force to the refrigerant
piping, drain piping, flanges or plastic parts.
• For the installation of 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.
• 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.
