In some applications e.g. when backing a turbomolecular pump, we recommend that you incorporate an inlet
isolation valve in the pipeline from the vacuum system to the pump, so that you can isolate the vacuum
system from the pump when it is switched off.
Ensure that the sealing surfaces are clean and scratch-free.
We recommend that you use an exhaust extraction system suitable for use with all of the process gases you will pump.
Ensure that the exhaust extraction system cannot become blocked or obstructed when the pump is operating. Use a
catchpot on the exhaust to prevent the drainage of contaminated condensation back into the pump.
A small amount of tip seal wear product may collect in the exhaust duct of the pump. The dust may be blown out
with the initial burst of air after the pump has been vented. This is quite common and the amount of dust seen will
reduce over time.
At high temperature (in excess of 250 °C) tip seal wear product will begin to decompose, giving rise to gaseous
fumes that can produce unpleasant symptoms.
3.9 Leak test the system
Leak test the system and seal any leaks found after you have installed the XDS pump, to prevent leakage of any
substances out of the system and leakage of air into the system.
