Troubleshooting
If the actuator does not fit properly on the valve body
during installation or the valve performs improperly
(e.g., never fully closes) after installation, check that
the black plastic attachment support ring has been
removed from the valve body top. See the Mounting
Actuators on Valve Body section.
