4. Turn the actuator to full open position.
5. Install the actuator.
6. Close the actuator until it just touches the seat (you will feel minor resistance on the
handle).
7. Open the actuator.
8. Remove the actuator.
9. Check the circumference of the diaphragm for even distribution of riboflavin (use a
blacklight to see this clearly).
If the circumference is evenly coated, the valve has minimal or no warping. If it is not
even, we recommend a pressure test to further determine if the valve is installed correctly.
If the valve does not pass a pressure test then most likely it has been warped out of
specifications. We then suggest the valve is removed and a new valve is reinstalled.
