(1) Horizontally install the silencer box base onto the hang bolts mounted in the ceiling. Ensure
that the load is evenly distributed among all the bolts.
(2) The hang bolts and their mounting condition must be strong enough to sustain the load.
(3) After installation, install a locknut to each hang bolt to prevent them from loosening.
(4) To make the fan earthquake-resistant, securely install the fan onto a shaped steel frame fixed
to a building structure.
