2. BEFORE INSTALLATION
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
Be sure to check the type of R410A refrigerant to be used before doing any work. (Using an incorrect
refrigerant will prevent normal operation of the unit.)
• When opening the unit or moving it after opening, be sure to lift it by holding on to the lifting lugs without
exerting any pressure on other parts, especially, 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 mate-
rial, where unpacking is unavoidable or protective plates together with a rope when lifting, to avoid damage
or scratches to the unit.
• Especially, do not unfasten packing case (top) guarding the control box until suspending the unit.
• Refer to the installation manual of the outdoor unit for items not described in this manual.
• Do not dispose of any parts necessary for installation until the installation is complete.
2-1 PRECAUTIONS
• Be sure to read this manual before installing the indoor unit.
• When selecting installation site, refer to the installation pattern.
• 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.
• 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.
• 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 volatile flammable gas like thinner or gasoline is used.
• 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.
