2. Rinse and drain the assembly as required (→  34).
3. Disconnect the assembly from the process.
4. Remove the assembly from the wall installation (→  39).
5. Using the clips, separate the assembly into the modules(→  37).
6. Replace or clean the seals.
7. Clean sealing surfaces of the modules before inserting new seals.
8. Use the clips to reassemble the modules back into the assembly.
Please note the following:
• Pay attention to the correct position of the modules (orientation, position, sequence).
• Ideally, mount the assembly lying on its side so that the seal can be inserted flat into the
mounting groove.
• Ensure that the seal is not displaced when attaching the next module.
• Tighten the screws evenly using a torque of 2.5 ± 0.5 Nm.
• Visually inspect the clips. When installed correctly, there should be no gaps between
them.
9. Carry out a leak test in advance at low water pressure, with the dummy plugs or plugs
installed and without the sensors.
10. Mount the assembly on the wall again.
11. Connect the assembly to the process.
12. Put the measuring point into operation (→  28), paying particular attention to

There are two different versions of the module seal:
• Gasket seals with bore hole
• Gasket seals with channel.
The correct selection of the seal depends on the flow direction of the adjacent modules in
each case. The flow direction is indicated by an arrow.
• The gasket seal with bore hole should be used if the arrows of the adjacent module
halves in question are at the same height (→  39).
• The gasket seal with channel should be used if the arrows of the adjacent module halves
in question are offset to each other →  39.
