Flushing the process gas into the control panel

1. Close all valves except LPV (if present).
2. Slowly open the process gas source valve and then the HPI valve to fill the entire area in which the process gas is to penetrate (pressure build-up).
3. Open valve PLI.

The process source pressure and the gas type properties are to be taken into account here.

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".
