WARNING
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.
(1) When placing the unit inside the ceiling, determine the pitch
of the suspension bolts referring to the dimensional data as
shown in Fig. 3-1 and Table 3-2.
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 (Fig. 3-3). (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 (Figs. 3-5 and 3-6). 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.
3-2. Suspending the Indoor Unit
Depending on the ceiling type:
•
Insert suspension bolts (Fig. 3-3)
or
•
Use existing ceiling supports or construct a suitable support
(Fig. 3-4).
This shows an example of installation.
