5. Push the pod completely into the valve drive body.
Be sure to install the pod in the correct orientation. Align the large slot in the pod with
the matching runner in the valve drive body.
If you cannot push the pod completely into the valve drive body, refer to the
Troubleshooting Tip (see further down in this section).
6. Tighten the spanner firmly with your hand only (without using any tool). If the
spanner is too tight, the valve may not switch. If you attempt to switch the valve, a
message appears, for example, Right (or Left) valve moving timeout error.
7. When the valve is replaced, the rotor seal is also replaced. Therefore, in Chromeleon,
update the service information for the rotor seal. Perform the LeftRotorSealChanged
command or RightRotorSealChanged command as appropriate.
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, the valve coupling is not aligned properly. Turn the coupling by
hand until you can push the pod completely into the body.
