Hanging structure
•
Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
3.1. Install the indoor unit on a ceiling strong
enough to sustain its weight
Warning:
The unit must be securely installed on a structure that can sustain its weight.
If the unit is mounted on an unstable structure, it may fall down causing
injuries.
3.2. Securing installation and service space
•
Select the optimum direction of supply airflow according to the configuration of
the room and the installation position.
•
As the piping and wiring are connected at the bottom and side surfaces, and
the maintenance is made at the same surfaces, allow a proper space properly.
For the efficient suspension work and safety, provide a space as much as
possible.

* If the optional long-life filter is installed, the dimensions of the air conditioner
increase.
Rear inlet:
Depth increases by 30 mm (*1)
Bottom inlet: Height increases by 30 mm (*2)
3.3. Combining indoor units with outdoor
units
For combining indoor units with outdoor units, refer to the outdoor unit installation
manual.
•
If necessary, reinforce the hanging bolts with anti-quake supporting members
as countermeasures against earthquakes.
* Use M10 for hanging bolts and anti-quake supporting members (field supply).
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.
5. Changing Bottom Inlet Specifications
1.
Remove filter
A
(6 screws).
2. Remove the bottom plate
B
(6 screws) and bend the slit portion inwards at a
right angle.

Caution:
When bending the bottom plate, be sure to protect yourself from its edges.
3.
Fit the bottom plate

to the rear of the main body.
4. Fit filter
A
to the underside of the main body (6 screws).

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.

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.
7. 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.
1
Select the thickness of insulating material by pipe size.
Pipe size
Insulating material’s thickness
6.4 mm to 25.4 mm
More than 10 mm
28.6 mm to 38.1 mm
More than 15 mm
