(5) Before suspending the indoor unit, remove the 2 or 3 screws on the
latch of the air-intake grilles, open the grilles, and remove them by
pushing the claws of the hinges as shown in Fig. 3-117. Then remove
both side panels sliding them along the unit toward the front after
removing the 2 attachment screws. (Fig. 3-118)
(6) Carry out the preparation for suspending the indoor unit. The
suspension method varies depending on whether there is a suspended
ceiling or not. (Figs. 3-119 and 3-120)
(7) Suspend the indoor unit as follows:
a) Mount 1 washer and 2 hexagonal nuts on each suspension bolt as
shown in Fig. 3-121.
b) Lift the indoor unit, and place it on the washers through the notches,
in order to fix it in place. (Fig. 3-122)
c) Tighten the 2 hexagonal nuts on each suspension bolt to suspend
the indoor unit as shown in Fig. 3-123.
NOTE
The ceiling surface is not always level. Please confirm that the indoor unit
is evenly suspended. For the installation 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. 3-124)
(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.
