3-23. Suspending the Indoor Unit

Depending on the ceiling type:

Insert suspension bolts as shown in Fig. 3-74

or

Use existing ceiling supports or construct a

suitable support as shown in Fig. 3-75.

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, deter-

mine the pitch of the suspension bolts referring to

the dimensional data on the previous page.

(Fig. 3-73)

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. 3-74.

(Cut the ceiling material, if necessary.)

(3)

Thread the 2 hexagonal nuts and washers (field

supply) onto the 4 suspension bolts as shown in

Figs. 3-76 and 3-77. Use 2 sets of nuts and

washers (upper and lower), so that the unit will

not fall off the suspension lugs.
