(System) Pressure Test

Positioning the Blank Nut

To test the complete system's pressure tightness, the blank nut should be
positioned at the column compartment outlet (or the outlet of the last
module before the detector).
If a specific component is suspected of causing a system leak, place the
blank nut immediately before the suspected component, and then run the
(System) Pressure Test again. If the test passes, the defective component is
located after the blank nut. Confirm the diagnosis by placing the blank
nut immediately after the suspected component. The diagnosis is
confirmed if the test fails.
