Decommissioning

The gas supply via the Purge device can be interrupted without additional risks. No special maintenance or preservation work is required during this time.

If the Purge device remains unused or disassembled for an extended period, a decommissioning processed must be carried out. In principle, decommissioning must be carried out in the following order:

1. Interrupt gas supply (see "Gas supply interruption").
2. Disconnect the process gas source from the Purge device .
3. Seal all open screw connections tightly (e.g. plug on process gas port).
4. Flushing through to the process (see "Flushing through to the process").
5. Close all valves.
6. Switch off controller.
