Supply plug fan airflow adjustment

1) Order write up (OWU) indicate design airflow, supply
and design air pressure drop.
2) Verify on site supply fan airflow. It should match
OWU design airflow.
3) If on site airflow is different from OWU design
airflow the actual supply and design air pressure
drop should be different from design values, Trane
service technician should be mandated to perform air
flow adjustement and optimization.
