Fix the suspension bolts securely in the ceiling
using the method shown in the diagrams (Figs.
3-33 and 3-34), 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. 3-34 and Table 3-2 to make the holes
in the ceiling.
