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 as
shown in the tables and diagrams under the section
"Required Minimum Space for Installation and Service"
on page 1-11-99.
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. (Cut the ceiling material, if necessary.)

(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts. 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.
