Installation Manual

2) Where applicable, create the ceiling opening that is
necessary for installation (for 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 (use either an 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 installation example, see the figure below.
1 Ceiling slab
2 Expansible hook (optional)
3 Installation hook (optional)
4 False ceiling
For details about installation other than standard
installation, contact your dealer.

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
space between the ceiling and the unit should be 20 mm
(0.8 in) or less. If the space between the ceiling and the
unit is more than 20 mm (0.8 in), attach sealing material
or recover the ceiling.

Adjust the position to ensure the gaps between the indoor
unit and the four sides of the false ceiling are even. The
indoor unit's lower part should sink into the false ceiling 24
