(7) Suspend the indoor unit as follows.
(a) Mount a washer and two hexagonal nuts on
each suspension bolt as shown in Fig. 1-58.
(b) Lift the indoor unit with a lifting machine to the
ceiling surface, and place it on the washers
through the notches, to fix it in place.
(Fig. 1-59)
(c) Tighten the two hexagonal nuts on each
suspension bolt to suspend the indoor unit as
shown in Fig. 1-60.
NOTE
A ceiling surface is not always level. Please confirm
that the indoor unit is evenly suspended. For the instal-
lation to be correct, leave a clearance of about 3/8"
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. 1-61)
(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. 1-62)
