5.4 Connections
Connecting the vac-
uum side
 The connection between the pumping station and the vacuum chamber should be kept
as short as possible and should have at least the nominal diameter of the pump flange.
Use a greater nominal diameter on line lengths > 5 m.
 Lay the pipes in such a way that the roots pump will not be subjected to any mechanical
tension.
– Suspension components should be integrated into the piping.
– Ensure that mating flanges are in a parallel position.
 Clear welded lines of any welding scales, loose parts etc. before installation.
If dust appears in the intake medium, a dust filter must be installed. When extracting va-
pours we recommend using condensate separators on the intake side and on the exhaust
side. Please enquire for details.
WARNING
There is a risk of injury if the system is not transported properly
Danger to life from falling or protruding loads if the system is not properly secured to
lifting devices or is not transported properly.
 Use suitable lifting devices and tools.
 Ensure that the weight is distributed evenly. Avoid danger of tipping.
 Pay attention to attachments and superstructures.
 Test the hanging for high center of gravity.
 Never stand under suspended loads.
WARNING
Exposed, rotating rolling pistons!
Fingers and hands can become crushed when the intake flange is open.
 Keep all body parts out of operating range of the rolling pistons.
 Use a wooden handle to rotate the rolling pistons during cleaning.
NOTE
Danger of intake of solid particles!
Even in clean processes, fouling from the system must be anticipated during initial
commissioning.
 Use a suitable start-up strainer at the intake connection (see accessories).
 Ensure that this strainer is only removed when the risk of solid particles entering the
pump can be excluded.
 Note loss of pumping speed if necessary.
