4. Fixing hanging bolts
4.1. Fixing hanging bolts
Hanging structure
•
Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
1 Reinforcing the ceiling with additional members (edge beam, etc.) must be
required to keep the ceiling at level and to prevent the ceiling from vibrations.
2 Cut and remove the ceiling members.
3 Reinforce the ceiling members, and add other members for fixing the ceiling
boards.
For wooden construction
•
Use the tie beam (for one story building) or second-floor beam (for two story
building) as strength members.
•
To hang the air-conditioner, use a hard square timber of more than 6 cm if the
distance between beams is less than 90 cm and a hard square timber of more
than 9 cm if the distance between beams is less than 180 cm.
5. Installing the unit
5.1. Hanging the unit body
s Bring the indoor unit to an installation site as it is packed.
s To hang the indoor unit, use a lifting machine to lift and pass through the
hanging bolts.
s Install the indoor unit before ceiling work.
[Fig. 5.1.1] (P.3)
A Unit body
* Two installation methods are available
<When hanging the indoor unit directly>
1. Attach a washer and nut(s) to each suspension bolt. (The washers and nuts
are to be supplied locally.)
2. Fit the indoor unit to each suspension bolt.
3. Make sure that the unit is positioned level, then tighten each nut.
[Fig. 5.1.2] (P.3)
A Nut
When using inlet duct
100 or more
When not using inlet duct

<When installing the suspension fixture prior to installation of the indoor unit>
1. Loosen each suspension fixture bolt slightly, and remove the fixture and U-
shaped washers.
2. Adjust each suspension fixture bolt.

3. Attach a washer, nut and suspension fixture to each suspension bolt. (The
washers and nuts are to be supplied locally.)
4. Hook the indoor unit to the suspension fixtures.
5. Make sure that the unit is positioned level, then tighten each nut.
[Fig. 5.1.3] (P.3)
A Be sure to attach a U-shaped washer (4 washers in total).

5.2. Confirming the unit's position and fix-
ing hanging bolts
[Fig. 5.2.1] (P.3)
A Level check
s Use the gage supplied with the panel to confirm that the unit body and
hanging bolts are positioned in place. If they are not positioned in place,
it may result in dew drops due to wind leak. Be sure to check the positional
relationship.
s Use a level to check that the surface indicated by A is at level. Ensure
that the hanging bolt nuts are tightened to fix the hanging bolts.
s To ensure that drain is discharged, be sure to hang the unit at level using
a level.
Caution:
Be sure to install the unit body at level.
