6. Set Recirculation Control Valve (gray), and Recirculation Flow Rate.
•
The recirculation valve should be set according to the table in tank.
•
Normal recirculation flow should be level with the top edge of the recirculation pipe line
cut-out spilling into Chamber 1.

7. Check/Set Aeration Balance Control Valve (blue).
•
The default, normal setting for the Aeration Control Valve is 50%.
•
Visually observe the airflow rates on each side of the plant by checking to see if bubbles
are evenly distributed on both sides of Chamber 3, The Aeration Chamber. If there is an
obvious discrepancy in airflow between the two sides, adjust the Aeration Balance Control
Valve so that the airflow is equal.
Important!
