4. Fixing hanging bolts
4.1. Fixing hanging bolts
(Use M10 hanging bolts. The bolts should be procured locally.)
(Give site of suspension strong structure.)
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 [2-3/8 in] if the distance between beams is less than 90 cm [35-13/32 in]
and a hard square timber of more than 9 cm [3-9/16 in] if the distance between
beams is less than 180 cm [70-27/32 in].

For reinforced concrete construction
•
As shown in the figure below, fix the hanging bolts, or use square timbers to fix
the hanging bolts.

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 joist construction.
[Fig. 5.1.1] (P.3)
A Unit body
5.2. Confirming the unit's position and fix-
ing hanging bolts
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 A A A A is at level. Ensure
that the hanging bolt nuts are tightened to fix the hanging bolts (Fig.
5.2.1).
s To ensure that drain is discharged, be sure to hang the unit at level using
a level.

6. Refrigerant pipe and drain pipe specifications
To avoid dew drops, provide sufficient antisweating and insulating work to the re-
frigerant and drain pipes.
When using commercially available refrigerant pipes, be sure to wind commer-
cially available insulating material (with a heat-resisting temperature of more than
100°C and thickness given below) onto both liquid and gas pipes.
Be also sure to wind commercially available insulating material (with a form
polyethylene's specific gravity of 0.03 and thickness given below) onto all pipes
which pass through rooms.

5.3. Changing to bottom intake specifica-
tions
Changing the bottom panel installation position. (Fig. 5.3.1)
1. Remove the flange B (C screws)
2. Remove the bottom panel A (6 screws)
3. Fit the bottom panel A to the rear of the main body. (6 screws)
4. Fit the flange B to the underside of the main body. (C screws)
