3-21. Suspending the Indoor Unit

Depending on the ceiling type:

•Insert suspension bolts as shown in Fig. 3-86 or

•Use existing ceiling supports or construct a suitable support as shown in Fig. 3-87.

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 on the previous page. (Fig. 3-84 and Table 3-3)

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. 3-86. (Cut the ceiling material, if nec- essary.)

(3)Thread the 3 hexagonal nuts and 2 washers (field supply) onto each of the 4 suspension bolts as shown in Figs. 3-88 and 3-89. 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.
