3-36. Suspending the Indoor Unit
Depending on the ceiling type:
Insert suspension bolts as shown in Fig. 3-115
or
Use existing ceiling supports or construct a suitable
support as shown in Fig. 3-116.
It is important that you use
extreme care in supporting the
indoor unit inside the ceiling.
Ensure that the ceiling is strong
enough to suport 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. 3-113)
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. 3-115.
(Cut the ceiling material, if necessary.)
(3) Suspend and fix the indoor unit using the 2 hexag-
onal nuts (field supply) and special washers (sup-
plied with the unit) as shown in Fig. 3-117.
