3. Where there is a machine that generates electromagnetic
wave and where voltage fluctuation often occurs such as
a factory.
Control system may malfunction and as a result the unit
may not properly operate.
4. Where flammable gas may leak, where carbon fibre or
ignitable dust is suspending in the air, or where volatile
flammables such as paint thinner or gasoline are
handled.
Operating the unit in such conditions may result in fire.

BEFORE INSTALLATION
Do not exert pressure on the resin parts when opening the
unit or when moving it after opening.
• When moving the unit while removing it from the box, be
sure to lift it by holding on to the four lifting lugs without
exerting any pressure on other parts, especially swing flap,
the refrigerant piping, drain piping, and other resin parts.
• Decide upon a line of transport.
• Leave the unit inside its packaging while moving, until
reaching the installation site. Use a sling of soft material,
where unpacking is unavoidable or protective plates
together with a rope when lifting, to avoid damage or
scratches to the unit.
• Refer to the installation manual of the outdoor unit for items
not described in this manual.
• Installation should only be carried out after checking in
advance the type of refrigerant to be used. (Using the wrong
refrigerant will prevent the unit from functioning properly.)
• Do not dispose of any parts necessary for installation until
the installation is complete.

like in kitchens. (Plastic parts may deteriorate.)
• Where corrosive gas like sulfurous gas exists. (Cop-
per tubing and brazed spots may corrode.)
• Where volatile flammable gas like thinner or gasoline
is used.
• 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.
