8.1 Overview of Regular Care and Maintenance Actions
The following maintenance schedule provides an overview of recommended and regular actions for ca-
ring and maintaining your analyser. Visual inspections are used to check the applicative need for care
and maintenance actions.
8.1.1 Tightness Test
After replacement of components, e.g. a reactor tube, a tightness test should be performed.
1. To run this test, the "status screen" in user level 2 must be called.
2. Set the pressure to 0.5 bar via the pressure regulator.
3. The screen shows the carrier gas inlet on the right side of the screen. This value must be
considered in this test all the time.
4. Bend off the black Viton hose (outlet of the radiator) with a hose clamp. The exam takes a few
minutes. The flow (carrier gas inlet) must drop to <5 l / h. If this is not the case, contact LAR AG
Technical Support.
5. At the end of the test loosen the kink in the hose and set the pre-pressure to 0.5 bar.
