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.)

REPARATIONS
BEFORE
INSTALLATION
1.
Relation of ceiling opening to unit and suspension bolt
position.
(See figure 3)
■
Use the installation guide (delivered with the unit) for exact
vertical positioning of the unit.
■
Installation is possible when opening dimensions are as follows.
When installing the unit within the frame for fixing ceiling
materials.
(See figure 4)
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, implement the refrigerant and
drain piping and wiring for remote controller (unnecessary for
wireless type) and indoor-outdoor unit casing outlet. 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 W3/8 or M10 size
bolt.)
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.

NOTE
Installation is possible with a ceiling dimension of
910 mm (marked with *). However, to achieve a ceiling-
panel overlapping dimension of 20 mm, the spacing
between the ceiling and the unit should be 35 mm or
less. If the spacing between ceiling and the unit is over
35 mm, attach ceiling material to the part or recover
the ceiling.
