Flushing the process gas into the pressure control panel

1. Close all valves and fully depressurise the pressure regulator by turning the of the handwheel anticlockwise as far as it will go.
2. Open the process gas source valve and then the HPI valve, so to fill the entire area in which the process gas is to penetrate (pressure build-up).
3. Now open valve PLI.
4. Slowly set the pressure regulator to the required outlet pressure.

In this process, the process source pressure and the gas type properties are to be taken into account.

The pressure control panel is now in a condition ready for operation.

If operation is not to be continued following the flushing process, proceed in accordance with "Gas supply interruption".
