method shown in the diagrams (Figs. 1-7 and 1-8), by
attaching them to the ceiling support structure, or by any
other method that ensures that the unit will be securely
and safely suspended.

(3) Determine the pitch of the suspension bolts using the
supplied full-scale installation diagram. The diagram
and table (Fig. 1-9 and Table 1-5) show the relationship
between the positions of the suspension fitting, unit, and
