Ignoring airflow arrows on plan
Follow airflow arrows before installing fittings, dampers, VAVs, louvers, and equipment connections.
Stop if
- Can you confirm airflow direction before I install this fitting/device?
Watch out
- Do not flip fittings or devices because they physically fit.
Check
- 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.
