INDOOR UNIT INSTALLATION
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:
Dimension of opening: 576~590
Unit size: 570
Dimension of
suspension bolts: 530

•
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).

1 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

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.
