When lifting with a lifting machine, in order to protect against damage,
reverse the unit body as is packed with the packing cap and lift it.
3.1. Securing installation and service space
[Fig. 3.1.1] (P.2)
•
Select a blowout direction suited for room shape, installation site and so on.
•
Piping, wiring and maintenance are all done on the bottom and the side. So,
secure the space given below for such work. Also, taking into consideration
serviceability and safety in hanging, secure as large space as possible.
4. Fixing hanging bolts
4.2. Ceiling hole and hanging bolt positions
•
Use the gauge supplied with the panel to fix hanging bolts so that the unit body
and ceiling hole are positioned in place as shown in [Fig. 4.2.1]. For how to use
the gauge, refer to the instruction manual supplied with the panel.
Notes:
•
The gauge may expand or shrink with changes in the temperature and
humidity. First be sure to check the product dimensions, and then use
the gauge.
•
The ceiling hole is adjustable as shown in [Fig. 4.2.1]. Align the centers
of both ceiling hole and unit body so that the unit body is not biased to
the ceiling hole and that the gaps between the ceiling hole edges and the
unit body’s external dimensions come to be identical.
•
Use M10 hanging bolts (for all bolts). (field supply)
•
Each hanging bolt must extrude C mm from the ceiling. It is possible to slide
the unit body 10 mm max. within part of the heights of the unit body and deco-
rative panel in order to make fine installation adjustments to the finished ceil-
ing surface. Sliding the unit body and incorporating a high-performance filter
requires the dimensions given in [Fig. 4.2.1]. To this, attach nuts which will fix
a hanging bracket as shown in [Fig. 4.2.1].

Affixed on the back surface of each split flow duct end connection is
insulating material. Use a cutter knife to cut the insulating material along
the end connection.

The amount of suction air coming through the outdoor air inlet can be
adjusted by making two cuts on the outdoor air inlet as shown in
[Fig. 3.3.1].
3.4. Combining indoor units with outdoor
units
For combining indoor units with outdoor units, refer to the outdoor unit installation
manual.
3.2. Split flow duct end connection - fresh
air intake

Knockouts are provided at each position as shown in the figure. Use them for
your purposes when installing the unit.

4.1. Fixing hanging bolts
(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.
•
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.
