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). 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.

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.

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, install fresh air inlet component kit and branch duct before
installing the unit.

Check if the unit is horizontally levelled.
-
Do not install the unit tilted. The indoor unit is equipped with a
built-in drain pump and float switch. (If the unit is tilted
against condensate flow, the float switch may malfunction
and cause water to drip.)

Check if the unit is levelled at all four corners with a water
level or a water-filled vinyl tube as shown in

Remove the paper pattern for installation. (For new ceilings
only.)
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.
