The following description applies for assemblies with POPL already fitted. If you are
retrofitting POPL, please refer to the instructions supplied with the spare parts kit.
1. Replace O-rings and damaged windows in the same way as for assemblies without
POPL. Follow the steps until you have re-installed the window rings on either side of the
assembly.
2. Release the 2 securing screws (item 6) on each window ring.
3. Clean the measuring gage (item 1) and insert it into the assembly until it is positioned
between the windows.
4. Now use the path length adjuster (item 4). Reduce the path length by gradually
screwing in the actuator (item 5) on both sides until the measuring gage just touches
both windows (→ diagram). Do not tighten too tightly.
5. Carefully remove the measuring gage from the assembly again.
6. Then tighten the securing screws to secure the actuator in place.
Remove the path length adjuster.
If possible: perform a pressure test with double the process pressure on the mounted flow
assembly. Perform another check with the measuring gage and adjust the path length if
necessary. Pressure tests guarantee the compression of the O-ring window seals and the
