Protect Dampers, Sensors, Liner, and Internal Parts During Installation
Identify internal parts before drilling, screwing, cutting, clamping, or using temporary supports. Mark their location on the outside so installation work does not strike or bind them.
This section has a damper and sensor upstream of the joint. I marked their locations-are these fastener and clamp zones clear before we close it?
Watch out
Do not assume the duct is empty, drive long screws blindly, or place clamps and temporary supports where they can crush liner or bind a blade or linkage.
Check
Review shop marks, access panels, labels, and submittals for internal components.
Look inside safely from available openings before choosing fastener or cut locations.
Mark no-drill and no-clamp zones on the exterior where needed.
Recheck operation or condition before the section is closed and inaccessible.
