WARNING
It is important that you use
extreme care in supporting
the indoor unit inside the
ceiling. Ensure that the ceil-
ing is strong enough to sup-
port 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 on the previous page. (Fig. 3-98
and Table 3-5)
Tubing must be laid and connected inside the ceil-
ing 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. 3-100.
(Cut the ceiling material, if necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts as
shown in Figs. 3-102 and 3-103. Use 1 nut and 1
washer for the upper part, and 2 nuts and 1 wash-
er for the lower part, so that the unit will not fall off
the suspension lugs.
