Follow these instructions if leakages emerge:
10. Deactivate the PHE [► chapter 6.3].
11. The PHE must be at the ambient pressure and the ambient temperature before work is begun.
12. Ensure that the pressure-free PHE is not tensioned beyond the final dimension specified on the name
plate. Follow the sequence while tightening the tensioning screws [► chapter 9.5.2].
