NOTICE
Malfunction and damage to the vacuum pump from inadmissible exhaust line installation
Negative pressure in the exhaust line causes malfunctions and damage to the vacuum pump. Nega-
tive pressure is permitted only in rotary vane vacuum pumps with magnetic coupling.
► When dissipating gases, make sure that the exhaust pressure is at least 250 hPa higher than the
intake pressure.

Connecting the exhaust side
1. Remove the blank flange from the exhaust flange.
2. Ensure that the centering ring with cone sieve and the O-ring are fitted in the exhaust flange.
3. Choose a minimum exhaust line cross section equal to the nominal diameter of the connection
flange.
4. Metal hoses with flange connections must be used exclusively in this regard.
5. Connect both flanges with a suitable circlip.
6. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
7. Route the piping downwards from the vacuum pump, to prevent condensate return.
8. Route process gases safely.
9. Use a suction device to prevent zone entrainment.
Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.
5.4 Grounding the vacuum pump
A suitable grounding cable must be connected to eliminate any applicative disruptive influences.
