11.3. Indoor Unit
11.3.1. HOW TO FIX INSTALLATION PLATE
The mounting wall is strong and solid enough to prevent it from
the vibration.
1. Mount the installation plate on the wall with 5 screws or
more.
(If mounting the unit on the concrete wall, consider using
anchor bolts.)
• Line according to the arrows marked on the bottom left
and right sides of the installation plate. The meeting point
of the line extension is the centre of the hole.
2. Drill the piping plate hole with ø70 mm hole-core drill.
• The hole centre of the right pipe is at the crossing of the
lines which extend vertically from the edge of the
installation plate, and, horizontally, from the side arrow
on the installation plate (see figure above.)
• The hole centre of the left pipe is at the crossing of the
lines which extend vertically from the downward arrow on
the installation plate, and, horizontally from the side
arrow on the installation plate (see figure above.)
• Drill the piping hole at either the right or the left and the
hole should be slightly slanted to the outdoor side.
11.3.2. TO DRILL A HOLE IN THE WALL
AND INSTALL A SLEEVE OF
PIPING
1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes about 15 mm from the
wall.
4. Finish by sealing the sleeve with putty or caulking
compound at the final stage.
11.3.3. INDOOR UNIT INSTALLATION

2. For the right and right bottom piping
: For left side piping, piping connection for liquid should be from
this line.
: For left side piping, piping connection for gas should be about
60 mm from this line.

750 mm from this line.
Caution
When the wall is hollow, please be sure to use the
sleeve for tube ass’y to prevent dangers caused by
mice biting the connecting cable.
