Secure the base framing or wall brackets using the manufacturer’s specified anchor bolt sizes. Torque all hardware to engineering specifications to guarantee resistance against structural vibration and seismic events.
: Before commissioning, the assembly manufacturer must verify mechanical operation, dielectric properties, and wiring. Even if previously tested at a workshop, these checks should be repeated after transport to the installation site.
Scrap paint from structural joints or tighten the star washers down to raw metal.
