4.13 Leak test the system
WARNING:
Process gases which leak from the pipelines will be dangerous to people and there
may be a danger of explosion or fire if air leaks into the pipelines
Uncontrolled air leaks may lead to flammable mixtures in the process gas pipelines. We
will accept no liability or warranty claims resulting from flammable mixtures caused by
air leaks.
Leak test the pipelines according to all local and national regulations, but as a minimum
the pump exhaust and the bypass pipelines must be tested.
1. Leak test the system.
2. Seal any leaks found.
