3-15. Suspending the Indoor Unit

Depending on the ceiling type:

Insert suspension bolts as shown in Fig. 3-63 or

Use existing ceiling supports or construct a suitable support as shown in Fig. 3-64.

WARNING

U

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. 3-61 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. 3-63. (Cut the ceiling material, if

 

necessary.)

(3)

Thread the 3 hexagonal nuts and 2 washers (field supply) onto

 

each of the 4 suspension bolts as shown in Figs. 3-65 and 3-66.

 

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
