- 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.
Use expansible 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.
Installation example see figure below.
2) Make the ceiling opening needed for installation where
applicable.(For existing ceilings.)
3) Install the installation hooks. (Use either a M8 or M10
size bolt. )
1 Ceiling slab
2 Expansible hook (optional)
3 Installation hook (optional)
4 False ceiling
contact your dealer for details.
For other installation than standard installation,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.
