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 given
previously. (Figs. 3-100 and 3-101)
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. 3-102. (Cut the ceiling material, if
necessary.)
(3) Suspend and fix the indoor unit using the 2 hexagonal nuts
(field supply) and special washers (supplied with the unit) as
shown in Fig. 3-104.
