Metal Truss Supported Ceilings. Figure 3 shows an SHM-11
unit suspended from a metal truss supported ceiling. Customer should
take care to determine that the truss will be sufficient to support the
weight. As shown, angle iron braces are secured between two steel
trusses. Rod length should be kept to a minimum and cut to length
as necessary.
In this instance, the rods instead will be installed in the exact same
fashion into the weld nuts found in the blower cabinet.
Be sure rods are threaded adequately into weld nuts, about 1˝ (25.4
mm) of rod extending inside the cabinet is acceptable.
Tighten lock nuts (item #3 in Figure 3) in place to be sure unit does not
vibrate lose or fall over time.
