What do I do when ignoring airflow arrows on plan?
Print Reading, Tags & LayoutFoundation print-reading starter — verify latest revision/detail
Follow airflow arrows before installing fittings, dampers, VAVs, louvers, and equipment connections.
Field checklist
- Find arrows on plan/details.
- Trace airflow to equipment/room.
- Check fitting direction and damper orientation.
- Mark airflow on staged pieces if needed.
- Ask if arrows conflict with field direction.
Ask foreman
Can you confirm airflow direction before I install this fitting/device?
Do not
Do not flip fittings or devices because they physically fit.
Why it matters
Many parts fit backwards but do not work backwards.
