Suspending the Indoor Unit
(1)
Place the full-scale diagram (supplied) on the
ceiling at the spot where you want to install the
indoor unit. Use a pencil to mark the drill holes.
(Fig. 3-64).
Since the diagram is made of paper, it may shrink or
stretch slightly because of high temperature or
humidity. For this reason, before drilling the holes
maintain the correct dimensions between the
markings.
(2)
Drill holes at the 4 points indicated on the full-
scale diagram.
(3)
Depending on the ceiling type:
a) Insert suspension bolts as shown in Fig. 3-65.
or
b) Use existing ceiling supports or construct a
suitable support as shown in Fig. 3-66.
It is important that you use
extreme care in supporting
the indoor unit from the
ceiling. Ensure that the
ceiling is strong enough to
support the weight of the
unit. Before hanging the
ceiling unit, test the strength
of each attached suspension
bolt.
(4)
Screw in the suspension bolts, allowing them to
protrude from the ceiling as shown in Fig. 3-66.
Distance “A” of each exposed bolt must be of
equal length.
(5)
Before suspending the indoor unit, remove its air-
intake grille and service cover. (Fig. 3-67)
(6)
Suspend the indoor unit as follows:
a)
Temporarily mount the supplied toggle wing
nuts at diagonal locations (Fig. 3-68) on the
suspension bolts.
