8.3 INSTALLATION

Opening of false ceiling and location of

suspension bolts

• Determine the final location and installation direction of

the indoor unit paying attention to the space for the piping,
wiring and maintenance.

•

Then cut out the false ceiling for the indoor unit installation

and install suspension bolts, as shown below:

(mm)

Unit size: 570

Dimension of

suspension bolts: 530

4-positions of

suspension bolts

Dimension of opening: 576~590

Piping

Drain piping

connection side

Optional panel

Unit size: 570

Dimension of

suspension bolts: 530

Dimension of opening: 576~590

N O T E

•

Ceiling work differs depending on the building structure. Consult with

a building constructor or an interior finish worker for more information.

•

Do not install electric light and the indoor unit to the same furring

of the ceiling. Otherwise, electric lights may flicker or vibrate due to

indoor unit operation.

Mounting of suspension bolts

•

Strengthen the opening parts of the false ceiling. Using a

steel C-profile makes the work easier.

•

Mount suspension bolts, as shown.

•

Strengthen suspension bolts with support plates as required
in preparation for an earthquake. Suspension bolts and

support plates shall be M10 (field-supplied).

For concrete slab:

150 to 160mm

Insert
(100 to 150kg)

For steel beam:

I-Beam

Suspension bolt

(W3/8 or M10)

For wooden beam:

Install the indoor unit to the tie beam (for single-storied building)

or to the second floor girder (for two-storied building), and use
sufficiently strong squared timber shown below.

Interval between beams

Squared timber

< 90 cm

6 square

< 180 cm

9 square

Mounting indoor unit

Pattern board for installation and scale for dimension of
opening

For installation work, the pattern board is required. The
pattern board for installation and the checking scale are
printed on the back side of the packing.

Cut off the checking scale for dimension of opening from

the packing. The usage is shown in the item (5).

Mounting position of the indoor unit

Check the mounting position of the indoor unit shown in

figure below:

N O T E

The air panel (optional) may be deformed if the levelness of the indoor

unit and the position of the suspension brackets are incorrect, and dew

condensation may occur due to air leakage from the gap between the

indoor unit and the air panel.
