2) Make the ceiling opening needed for installation where
applicable.(For existing ceilings.)
- 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.
3) Install the installation hooks. (Use either a M8 or M10 size
bolt. )
Use expandable hooks, sunken anchors or other field supplied
parts to reinforce the ceiling in order to bear the weight of the
unit. Adjust clearance from the ceiling before proceeding further.
See figure below for installation example.

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