Installation is possible with a ceiling dimension
NOTE:
of 600 mm / 23.62in(marked with * ) . However,
to achieve a ceiling-panel overlapping dimension
of 15 mm / 0.59in, the spacing between the
ceiling and the unit should be 20 mm / 0.79in
or less.If the spacing between ceiling and the
unit is over 20 mm / 0.79in, attach sealing
material in the part or recover the ceiling.
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 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.
