6. Put the measuring point into operation (→  28), paying particular attention to
leak-tightness.

CAUTION
When removing a sensor with a glass shaft, the glass may shatter.
Risk of injury from glass splinters!
‣
When handling these sensors, always wear protective goggles and appropriate
protective gloves.
To replace or remove the sensors, e.g. for external calibration or maintenance, proceed as
follows:
1. Take the measuring point out of operation (→  34).
2. Rinse and drain the assembly as required (→  34).
3. Remove the relevant sensors.
• Remove the cable or connector.
• Unscrew the coupling nut or unscrew the sensor directly.
• Pull sensor out through opening in assembly.
4. Install calibrated or new sensors.
5. Connect the cable or connector.
6. Put the measuring point into operation (→  28), paying particular attention to
leak-tightness.
9.2.6 Replacing seals in valves, process adapters, plugs and sensors
Seals in valves, process adapters, plugs and sensors can be replaced easily by dismantling
the relevant components. The seals can also be replaced while the assembly remains at the
mounting location. To do so, proceed as follows:
1. Take the measuring point out of operation (→  34).
2. Rinse and drain the assembly as required →  34.
3. Remove the relevant components.
4. Replace the seals.
5. Install the components.
6. Put the measuring point into operation (→  28), paying particular attention to
leak-tightness.
The needle valves at the inlet and outlet can only be dismantled if the assembly with
additional valves is integrated into the process.
9.2.7 Replacing the seals and cleaning between the modules
The module seals are located in the channel between the modules. To replace them, the
assembly must be disassembled at the clips and then reassembled correctly. To do so,
proceed as follows:
1. Take the measuring point out of operation (→  34).
