Connecting the vacuum side
1. Remove the blank flange from the vacuum flange.
2. Make sure that the centering ring with cone sieve and the O-ring are in the vacuum flange.
3. Establish the shortest possible connection between the vacuum pump and vacuum chamber;
equivalent to the nominal flange diameter as a minimum.
4. Metal hoses with flange connections must be used exclusively in this regard.
5. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
6. Connect both flanges with a circlip (DN 16 ISO-KF).
7. Protect the vacuum pump against contamination using suitable measures.

WARNING
Risk of fatalities due to escaping process media
The manufacturer has no influence on the media being supplied with the vacuum pump. Process me-
dia are often toxic, combustible, potentially explosive and/or reactive in other ways. There is a risk of
serious or even fatal injuries if these media are permitted to leak into the atmosphere.
► Refer to the corresponding local guidelines. This information can be obtained from the Depart-
ment of Health and Safety at Work of the user.
► Prevent zone entrainment.
► Connect the pump outlet to the suction system for hazardous media on the system.
► Perform regular inspections to ensure that there are no leaks at the connection between vacuum
pump and suction pipes.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
