TinnerFlow™3rd YearEquipment ConnectionsRED · Stop / Verify
A VAV that cannot be serviced is not “done” just because it is hung. Stop before cover, verify service side/access, and coordinate a shift, rotation, hand change, or revised layout.
Equipment needs access after the ceiling closes. If an X-brace, wall, pipe rack, or other obstruction blocks the VAV control panel or coil access, the install will create a service and inspection problem.
Do not assume “they can reach it later.” Check the approved access requirements from the submittal/project detail and bring a practical recovery: mirror/handed box if available, shift the box, alter spool lengths, rotate service side if allowed, or coordinate a different location.
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
