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.
Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.

Protective cover
Procedure
1. Remove the protective cover from the exhaust connection.
2. Choose a minimum exhaust line cross section equal to the nominal size of the connection.
3. Install a vacuum connection with small flange components, e.g. screw-in flange DN 16 ISO-KF

4. Route the piping downwards from the vacuum pump, to prevent condensate return.
5. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
5.6 Remove transportation lock
The transportation lock fixes the spring-mounted floor panel diagonally with 2 knurled screws.
