Suspending The Indoor Unit - Panasonic S-12MU1U6 Installation Instructions Manual

3-21. Suspending the Indoor Unit

Depending on the ceiling type:
• Insert suspension bolts as shown in Fig. 3-86
or
• Use existing ceiling supports or construct a suitable support as
shown in Fig. 3-87.
WARNING
(1) When placing the unit inside the ceiling, determine the pitch of the
suspension bolts referring to the dimensional data on the previous
page. (Fig. 3-84 and Table 3-3)
Tubing must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
tubing into position for connection to the unit before placing the
unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude from the
ceiling as shown in Fig. 3-86. (Cut the ceiling material, if
necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (fi eld supply) onto
each of the 4 suspension bolts as shown in Figs. 3-88 and 3-89.
Use 1 nut and 1 washer for the upper part, and 2 nuts and 1
washer for the lower part, so that the unit will not fall off the
suspension lugs.

It is important that you use extreme care
in supporting the indoor unit inside the
ceiling. Ensure that the ceiling is strong
enough to support the weight of the unit.
Before hanging the unit, test the strength
of each attached suspension bolt.
