3. Installation of outdoor unit
Part 3 Design and installation
3.1.5 Before installation
• During product unpacking and removing it from the packing case, be sure to lift it without exerting any pressure
on other parts, especially, horizontal flaps, the refrigerant piping, drain piping, and other resin parts.
• Be sure to remove a cushion (corrugated paper) located between the heat exchanger and the right air filter.
• Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect refrigerant will pre-
vent 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.
• For the installation of an outdoor unit, refer to the installation manual attached to the outdoor unit.
• When using the wireless remote controller, refer to the installation manual attached to the wireless remote controller.
• Entrust installation to the place of purchase or an authorized serviceman. Improper installation could lead to leaks and in
worst 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 the worst cases, electric shock or fire.
