4 INSTALLATION

WARNING

•Install the air conditioner certainly to sufficiently withstand the weight.

•If the strength is insufficient, the unit may fall down resulting in human injury.

•Perform a specified installation work to guard against strong wind or earthquake.

•An incomplete installation can cause accidents by the units falling and dropping.

REQUIREMENT

Strictly comply with the following rules to prevent damage of the indoor units and human injury.

•Do not put a heavy article on the indoor unit. (Even units are packaged)

•Carry in the indoor unit as it is packaged if possible.

If carrying in the indoor unit unpacked by necessity, be sure to use buffering cloth, etc. to not damage the unit.

•To move the indoor unit, hold the hooking metals (4 positions) only.

Do not apply force to the other parts (refrigerant pipe, drain pan, foamed parts, or resin parts, etc.).

•Hanging bolt pitch of air inlet chamber side is different (centre position), make sure not to make mistake to install the setting direction.

•Carry the package by two or more persons, and do not bundle it with plastic band at positions other than specified.

nInstallation of hanging bolt

•Consider the piping/wiring after the unit is hung when determining the location of the indoor unit installation and orientation.

•After the location of the indoor unit installation has been determined, install hanging bolts.

•For the dimensions of the hanging bolt pitches, refer to the external view.

•When a ceiling already exists, lay the drain pipe, refrigerant pipe, system interconnection wires, and remote controller wires to their connection locations before hanging the indoor unit.

Procure hanging bolts washer and nuts for installing the indoor unit (these are not supplied).

Treatment of ceiling

The ceiling differs according to structure of building.

For details, consult your constructor or interior finish contractor.

In the process after the ceiling board has been removed, it is important to reinforce ceiling foundation (frame) and to keep horizontal level of installed ceiling correctly in order to prevent vibration of ceiling board.

•Attach the nuts and the M10 flat washers to the hanging bolt.

•Put washers at up and down of the hanging bracket of the indoor unit to hang down the indoor unit.

•Using a level vial, check that four sides are horizontal. (Horizontal degree: Within 5mm)
