Connecting the process gas source

Connect the hoses. Proceed as described in the instruction manual for the respective hose.

1. Place the process gas source in front of the bracket and secure with the safety chain.
2. Remove and retain the protective cap and sealing nut on the process gas source.
3. Remove the plug from the gas connection.
4. Check connection thread and sealing. A new sealing must be used for each gas source exchange.
5. Screw the gas connection onto the gas source valve by hand and tighten it gas-tight with a spanner as required.
6. Perform a leak test as pressure or leak test. The HPI remains closed during this process, if possible (see "Exchanging the process gas source").
   The HPI may not only be the high pressure connection block or input, but in some versions may also consist of a ball valve or shut-off valve.
