Complete a tightness test by checking the entire gas route (from the
cylinder/pipeline to the device) using a gas detector.
Seal any leaks properly.
Set the regulators and valves to the required values.
Disconnect blocked lines from the switched-off device and flush the pipeline with
non-flammable gas to remove any blockages and deposits while observing the
maximum admissible pressure.
Discharge the flushing gas properly.
Use suitable gas detectors for the tightness test. These must reliably
display even very small quantities of the possibly leaking process,

The connection plugs on the edge of the terminal board must always be
inserted until they lock. Check that they are secure.
CAUTION
Tighten the screws on any unused terminals.
