Where applicable, create
the ceiling opening
that is
ne
cessary
for installation (
f
or existing ceilings)
- From the
side of the opening to the casing outlet, implement the
refrigerant and drain piping and wiring for
the
remote control
(unnecessary for
the
wireless type). Refer to each piping or
wiring
section.
- After making an opening in the ceiling,
you may need
to
reinforce
the
ceiling beams to
maintain
the ceiling level and to
prevent
it
from vibrating. Consult the builder for details.
3)
Install the installation hooks (
u
se either a
n
M8 or M10
bolt)
Use expansible hooks, sunken anchors
,
or other field
-
supplied
parts to reinforce the ceiling
so that it can
bear the weight of the
unit. Adjust
the
clearance from the ceiling before proceeding.
For
an i
nstallation example
,
see
the
figure below.
1 Ceiling slab
2 Expansible hook (optional)
3 Installation hook (optional)
4 False ceiling

Installation is possible with a ceiling dimension of 600 mm
(
23.6
in
)
(marked with * ). However,
to achieve a
ceiling-panel overlapping dimension of 15 mm
(
0.6
in
)
, the
spac
e
between the ceiling and the unit should be 20
mm
(
0.8
in
)
or less.
If the spac
e
between
the
ceiling and the
unit is
more than
20 mm
(
0.8
in
)
, attach sealing material
or recover the ceiling.
