Suspending the Indoor Unit
Depending on the ceiling type:
•
Insert suspension bolts (Fig. 1-11-22)
or
•
Use existing ceiling supports or construct a suitable
support (Fig. 1-11-23).

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 Figs. 1-11-19 and 1-11-20.
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 plac-
ing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to protrude from
the ceiling (Fig. 1-11-22). (Cut the ceiling material, if necessary.)
(3) Thread the 3 hexagonal nuts (Field supply) and 2 washers
(Supplied) onto each of the 4 suspension bolts (Figs. 1-11-24
and 1-11-25).
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.

Installing a drain pan (Field supply) could protect against
condensation and leaks.
Drain pan size should be over the tube connections and any
place that would condense water.
