WARNING
Risk of crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
► Keep limbs out of the reach of the roots pump.
NOTICE
Property damage from intake of solid particles
During commissioning, there is a risk of damage to the suction chamber from dirt from the system or
the pipes.
► Use a suitable protective strainer ("start-up strainer") in the intake flange.
► Ensure that this strainer is only removed when the risk of solid particles entering the vacuum
pump can be excluded.
– Observe any pumping speed decrease.
Required tools
● Ring spanner,
WAF 13
with flange DN 100 ISO-F
● Ring spanner,
WAF 24
with flange DN 100 PN16
Procedure
1. Degrease the connection flange.
2. Clear welded lines of any tinder, loose parts or similar before installation.
3. Route the piping between the vacuum pump and vacuum chamber so that it remains as short as
possible; at a minimum, the nominal diameter of the pump flange.
4. Select a larger nominal diameter for pipe lengths > 5 m.
5. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
– Install a bellows in the piping if necessary.
6. Always use
all
prescribed screws to fasten the flange.
