Ceiling Type (T1 Type)
6-19. 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. 1-50).
NOTE
Since the diagram is made of paper, it may shrink or
stretch slightly because of high temperature or
humidity. 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. 1-51.
or
(b) Use existing ceiling supports or construct a
suitable support as shown in Fig. 1-52.
WARNING
It is important that you use
extreme care in supporting the
indoor unit from the ceiling.
Ensure 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. 1-52.
The distance of each exposed bolt must be of
equal length within 2 inches. (Fig. 1-53)
