12.3 INSTALLATION
12.3.1
Opening of False Ceiling and Location of
Suspension Bolts
1
Determine the final location and installation direction of
the indoor unit paying attention to the space for the piping,
wiring and maintenance.
2
Then cut out the false ceiling for the indoor unit installation
and install suspension bolts.

Mounting Suspension Bolts
1
Strengthen the opening parts of the false ceiling. Using a
ductor makes the work easier.
2
Strengthen suspension bolts with support plates as required
in preparation for an earthquake. Suspension bolts and
support plates shall be M10 (field-supplied).
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.

Pattern Board for Installation and Scale for Dimension of
Opening
a.
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.
b.
Cut off the checking scale for dimension of opening from
the packing.

Mounting Position of the Indoor Unit
?
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.
Check the mounting position and the positional relation
between indoor unit and the air panel in the following figure.
