Opening a ceiling and installation of hanging bolts

<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.

(1)Cut and remove the ceiling foundation.

(2)Reinforce the cut surface of ceiling foundation, and add ceiling foundation for fixing the end of ceiling board.

<Installation of hanging bolt>

Use M10 hanging bolts (4 pcs, to be local procure). Matching to the existing structure, set pitch according to size in the unit external view as shown below.

Hanging bracket

Hang up the main unit by hanging the nut of hanging bolt to T groove of hanging bracket of the main unit.

Using the level vial, etc., set the horizontal level of the main unit within 5mm.

Using the installation gauge, check and adjust the positional relation between the main unit and ceiling opening hole, and hanging-up height of the main unit. (Direction to be used is indicated on the installation gauge.)

1)Check lower side of the indoor unit locates at position (12 to 17) mm higher than the lower surface of the ceiling board. (4 corners)

2)Check clearance between side of the indoor unit and the

ceiling board is 20 to 30mm. (Common to 4 corners)
