Layout isolation pads, (provided by contractor), according to the design and layout.
Place bases on isolation pads.
Insert legs of duct support into bases and attach with 2-1/2” bolt and 1/2” nut.
Space out pipe supports according to specifications. This should be done before any weight is supported.
*Attach horizontal bracing to legs of duct supports, (approximately 3/4” of the way up the height of the support) with 3” bolt and 1/2” nut. NOTE: If double or triple bracing is required, designated locations will be marked on support legs.
Adjust width up to bottom of ducting.
Make sure duct and duct supports are level, both vertically and horizontally, and proper spacing is maintained per design specifications.
Check that the weight of the ducting is distributed evenly throughout the system.
