WARNING
• It is important that you use extreme care in supporting
the indoor unit from the ceiling. Ensure that the ceiling
is strong enough to support the weight of the unit.
Before hanging the ceiling unit, test the strength of
each attached suspension bolt.
(4)
Screw in the suspensions bolts, allowing them to
protrude from the ceiling as shown in Fig. 3-16. The
distance od each exposed bolt must be of equal length
within 50 mm. (Fig. 3-17)
(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. 3-18. Then remove both side
panels sliding them along the unit toward the front after
removing the two screws which fix them. (Fig. 3-19).
(6)
Preparation for suspending the indoor unit. The
suspension method varies depending on whether the
unit is next to the ceiling or not. (Fig. 3-20 and 3-21).
(7)
Suspend the indoor unit as follows.
(a) mount a washer and two hexagonal nuts on each
suspension bolt as shown in Fig. 3-22.

(b) Lift the indoor unit, and place it on the washer
throught the notches, so as to fix it in place.(Fig. 3-23)
(c) Tighten the two hexagonal nuts on each suspension
bolt to suspend the indoor unit as shown in Fig. 3-24.
NOTE
A 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 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 have to pass towards the rear
of the unit, make holes in the wall. (Fig. 3-25)
(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. 3-26)
NOTE
The hole should be made at a slight downxard slant to the
outside.
