3-36. Suspending the Indoor Unit
Depending on the ceiling type:
Insert suspension bolts as shown in Fig. 3-120
●
or
Use existing ceiling supports or construct a suitable support as
●
shown in Fig. 3-121.
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 given
previously. (Figs. 3-118 and 3-119)
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. 3-120. (Cut the ceiling material, if
necessary.)
(3) Suspend and fi x the indoor unit using the 2 hexagonal nuts (fi eld
supply) and special washers (supplied with the unit) as shown in
Fig. 3-122.
