b) Lift the indoor unit, and place it on the washers through
the notches, in order to fix it in place. (Fig. 3-14)
c) Tighten the 2 hexagonal nuts on each suspension bolt to
suspend the indoor unit as shown in Fig. 3-15.
NOT E
The ceiling surface is not always level. Confirm that the indoor
unit is evenly suspended. For the installation to be correct,
leave a clearance of about 10 mm between the ceiling panel
and the ceiling surface and fill the gap with an appropriate
insulation or filler material.
(8) If the tubing and wiring are to go towards the rear of the
unit, make holes in the wall. (Fig. 3-16)
(9) Measure the thickness of the wall from the inside to the
outside and cut PVC pipe at a slight angle to fit. Insert the
PVC pipe in the wall. (Fig. 3-17)
NOT E
The hole should be made at a slight downward slant to the
outside.

Duct for Fresh Air
There is a duct connection port (knock-out hole) at the right-rear
of the top panel of the indoor unit for drawing in fresh air. If it
is necessary to draw in fresh air, remove the cover by opening
the hole and connecting the duct to the indoor unit through the
connection port. (Fig. 3-18)

Shaping the Tubing
Fig. 3-14
The positions of the refrigerant tubing connections are
shown in the figure below. (The tubing can be routed in 3
directions.) (Fig. 3-19)
* When routing the tubing out through the top or right sides,
knock out the appropriate parts in the top panel and cut
notches in the side panel (Fig. 3-18).
* When routing the tubing out through the top, the optional
L-shape tubing kit is required.
Fig. 3-15
If the tubing is to be routed out together, use a box cutter or
similar tool to cut out the part of the rear cover indicated by
the marked area (Fig. 3-20), to match the positions of the
tubes. Then draw out the tubing.
