Branch takeoff facing wrong direction
Verify branch direction before sealing. A takeoff facing the wrong way can starve the branch or create noise/turbulence.
Watch out
- Do not assume any branch direction works as long as it connects.
Check
- Confirm airflow direction in the main duct.
- Check the takeoff orientation against the shop drawing/detail.
- Verify the branch serves the correct diffuser/room.
- Look for damper position and access before sealing.
- Ask before rotating/cutting/moving the takeoff.
