Checking the system for leaks
NOTICE
Risk of gas leakage
When the outlet flow is significantly less than the inlet flow, the device system has a gas
leak.
¡
Check all connection pieces, for example with a foamy tenside solution.
¡
Only put the device into operation when the gas leak has been eliminated.
The system tightness is automatically checked at the gas outlet of the analyzer.
