Insert 4 mounting brackets with angles pointing away from housing. In approximate location between joists where housing will be
located, drive 2 nails (see dimensions “A” and “B” in Fig. 2) leaving 1/4” of nail projecting. Position one set of brackets over nails and
drop in to place. Extend the remaining mounting brackets to the adjacent joist and repeat nailing procedure. Finish driving nails and
adjust housing between ceiling joists.
