4 Use suspension bolts for installation. Check whether the ceiling is
strong enough to support the weight of the indoor unit. If there is a
risk, reinforce the ceiling before installing the unit.
(The installation pitch is marked on the paper pattern for installation.
Refer to it to check for points requiring reinforcing.)
Space required for installation see figure 2 ( : air flow direction)

NOTE
Installation is possible with a ceiling dimension of
26 in. (660 mm). However, to achieve a ceiling-panel
overlapping dimension of 13/16 in. (20 mm) (marked
with*), the spacing between the ceiling and the unit
should be 1-12/16 in. (45 mm) or less. If the spacing
between ceiling and the unit is over 1-12/16 in.
(45 mm), attach ceiling material to the part or recover
the ceiling.
2 Make the ceiling opening needed for installation where applicable.
(For existing ceilings.)
- Refer to the paper pattern for installation for the ceiling opening
dimensions.
- Create the ceiling opening required for installation. From the side
of the opening to the casing outlet or inspection opening,
implement the refrigerant and drain piping and wiring for remote
controller (unnecessary for wireless type). Refer to each piping or
wiring section.
- After making an opening in the ceiling, it may be necessary to
reinforce ceiling beams to keep the ceiling level and to prevent it
from vibrating. Consult the builder for details.
3 Install the suspension bolts.
(Use either a M8-M10 size bolt or equivalent.)
Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to reinforce the
ceiling in order to bear the weight of the unit. Adjust clearance from
the ceiling before proceeding further.

For other installation than standard installation,
contact your dealer for details.
Indoor unit installation
When installing optional accessories (except for the decoration panel),
read also the installation manual of the optional accessories.
Depending on the field conditions, it may be easier to install optional
accessories before the indoor unit is installed. However, for existing
ceilings, always install fresh air intake kit before installing the unit.

Install the unit in the ceiling opening.
- Attach the hanger bracket to the suspension bolt. Be sure to fix it
securely by using a nut and washer from the upper and lower
sides of the hanger bracket.
- Securing the hanger bracket (See figure 5)
1 Nut (field supply)
2 Washer (supplied with the unit)

4 Double nut (field supply, tighten)
2 Fix the paper pattern for installation. (For new ceilings only.)
- The paper pattern for installation corresponds with the
measurements of the ceiling opening. Consult the builder for
details.
- The center of the ceiling opening is indicated on the paper
pattern for installation. The center of the unit is indicated on the
unit casing.
- The printing pattern can be rotated by 90° to be able to indicate
the correct dimensions on all 4 sides.
- After cutting of the printing pattern for installation from packing,
attach the paper pattern for installation to the unit with the
attached screws as shown in figure 7.
