Connecting the process gas source

Connect the pig tails. Proceed as described in the instructions for use for the respective pig tail.

The compression fitting of Spectron pig tails is pre-installed at the factory. Insert the end of the pipe with the union nut into the thread fitting of the process gas valve as far as it will go.

Now hand-tighten the union nut and then tighten by approximately 1/8 of a turn with a matching wrench. To do this, hold the screw fitting with a second wrench.

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.
6. Perform a leak test as pressure or leak test. The HPI remains closed in this process (see "Exchanging the process gas source").
