Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.
Connecting the fore-vacuum side
1. Choose a minimum pipe cross section equal to the nominal diameter of the pressure flange.
2. Clear welded lines of any scaling, loose particles etc. prior to installation.
3. Route the pipes so that no mechanical stresses can act on the roots pump or the backing pump.
4. Install a bellows in the piping if necessary.
5. Ensure that mating flanges are in a parallel position.
6. Install the pipes downward from the vacuum pump, so that condensate does not flow back in.
5.6 Connect the switch box
CAUTION
Electric shock and damage to the vacuum pump and electronic drive unit due to improper
connection and disconnection of components
With existing power supply connection to the switch box, there is a risk of electric shock when making
contact with the motor connecting plug. Even after the power supply has been switched off, the vac-
uum pump continues to deliver electrical energy during its run-down period. If the units are discon-
nected prematurely, there is the risk of electric shock, and destruction of electric components.
► Always interrupt the power supply connection at the switch box before connecting the power sup-
ply plug to the motor.
► With existing power supply connection to the switch box or when the pistons are running, never
disconnect the motor connecting plug.
► After switching off, wait at least another 5 minutes until the capacitors have discharged before
separating the cable connection.
