Troubleshooting Tip
If you cannot push the pod completely into the valve drive body, the position of the valve
coupling does not match the position of the valve drive.
1. Switch the valve into another position and try again.
2. If this does not help, turn the pod in the valve drive body until the valve coupling locks
in place in the drive. Continue turning to align the locating pin on the pod with the
opening in the valve drive body, and then push the pod completely into the body.

4. Unscrew and remove the locking ring (spanner). Unscrew the spanner using only your
hand. Do not use a wrench. Grasp the pod and pull out firmly to remove the pod from
the valve drive body.
To facilitate removing the valve pod, you may use the so-called pod popper. Place the tab
of the popper into one of the drain holes on the stator ring. Unscrew the spanner (using
only your hand) while holding the popper in place with pressure. This will force the pod
out. Unscrew the spanner until the pod is completely removed from the valve drive body.
