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.

3-25. 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. 3-91).
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. 3-92.
or
b) Use existing ceiling supports or construct a
suitable support as shown in Fig. 3-93.

* If the optional drain up kit is installed, create a ø3-15/16" hole along the dotted line (part marked with * in figure).
(4) Screw in the suspension bolts, allowing them to
protrude from the ceiling as shown in Figs. 3-92
and 3-93. The distance of each exposed bolt must
be of equal length within 1-15/16". (Fig. 3-94)
