Ceiling-Mounted Type (TS Type)
3-10. Suspending the Indoor Unit
(1)
Place the full-scale diagram (supplied) on the
ceiling at the spot where you want to install the
indoor unit. Use a pencil to mark the drill holes.
(Fig. 3-19)
NOTE
Since the diagram is made of paper, it may shrink or
stretch slightly because of high temperature or humid-
ity. For this reason, before drilling the holes maintain
the correct dimensions between the markings.
(2)
Drill holes at the 4 points indicated on the full-
scale diagram.
(3)
Depending on the ceiling type:
a) Insert suspension bolts as shown in Fig. 3-20.
or
b) Use existing ceiling supports or construct a
suitable support as shown in Fig. 3-21.
It is important that you use
extreme care in supporting
the indoor unit from the
ceiling. Enure that the ceiling
is sufficiently 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 suspension bolts, allowing them to
protrude from the ceiling as shown in Fig. 3-21.
The distance of each exposed bolt must be of
equal length within 2 inches. (Fig. 3-22)
