5-2. Suspending the Indoor Unit
Depending on the ceiling type:
•
Insert suspension bolts (Fig. 1-110)
or
• Use existing ceiling supports or construct a suitable support
(Fig. 1-111).
Hole-in-anchor
Hole-in-plug
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 suspending 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
Fig. 1-108 and Table 1-11.
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 (Fig. 1-110). (Cut the ceiling material, if necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (field supply) onto each of the 4 suspension bolts (Figs. 1-112 and 1-113).
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.
