WARNING
It is important that you use extreme care in supporting
the indoor unit from 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) Before suspending the unit from the ceiling, determine the
pitch of the suspension bolts referring to the dimensional
data given previously. (Figs. 3-1 and 3-2)
(2) Screw in the suspension bolts allowing them to protrude
from the ceiling as shown in Fig. 3-3. (Cut the ceiling
material, if necessary.)
(3) Suspend and fix the indoor unit as shown in Fig. 3-6 using
vibration absorbers, sound insulation brackets and the
material shown in Fig. 3-5. Note that all fixing material
must be field-supplied.
