8.5.23 Check the Gas Cooling Pipes

1. Unscrew the 3 or 6 connection pieces with the tube connectors.

2. Carefully pull the relevant gas cooling pipe upwards out of the cooler guide.

3. Check the cleanliness of the gas cooling pipe removed (Note that the white silicone-free, heat-

conductive paste is not contamination).

4. If contamination is ascertained, cleaning is necessary (Chapter 8.5.12 on page 176).

5. Once the test criterion is met, refit the gas cooling Pipe, reconnect the tubes correctly to the tube

connectors and proceed with the next step.

Warning

Damage to the gas cooling pipes

Do not pull the gas cooling tubes out of the welded hose connection as the

connection could break off.

The images of the gas cooler must not be cleaned with sharp objects, as other-

wise the transition surface from the cooler to the gas cooling tube will be da-

maged.

Pay attention to the correct connections of the hose connections, since a

change of the hoses can lead to wrong measuring results.
