Mounting method
• In existing construction, remove enough
ceiling panels to provide clearance space
for mounting unit to ceiling joists.
• Before beginning the installation, inspect
the unit location, test the strength of the
ceiling joists to insure they will support
the weight of the unit.
• Determine mounting method:
– On wooden beams use threaded rods,
washers, and nuts to suspend support
brackets.
– With metal structures, secure thread-
ed rods on an existing angle or install
a new support angle.
– On newly built concrete slabs secure
threaded rods with inserts and em-
bedded bolts.
– For previously built concrete slabs
install hanging bolts with an expan-
sion anchor.
• Follow local building codes for required
safety cables, braces, etc.
