3-1. Preparation for Suspending

This unit uses a drain pump. Use a carpenter's level to check
that the unit is level.

3-2. Suspending the Indoor Unit

(1) Fix the suspension bolts securely in the ceiling using the
method shown in the diagrams (Figs. 3-1 and 3-2), by
attaching them to the ceiling support structure, or by any
other method that ensures that the unit will be securely
and safely suspended.
(2) Follow Fig. 3-2 and Table 3-1 to make the holes in the
ceiling.

(3) Determine the pitch of the suspension bolts using the
supplied full-scale installation diagram. The diagram
and table (Fig. 3-3 and Table 3-2) show the relationship
between the positions of the suspension fitting, unit, and
