Concentrator plus/Vacufuge® plus — Operating manual
Connect vacuum pump with external power supply
Requirement
• Additional power source for the vacuum pump.
• Solenoid valve for controlling the vacuum pump via the basic device (see Accessories on
p. 43)
• 2 connecting hoses (length: max. 50 cm, inner diameter: 8 mm, chemical resistant and
suitable for vacuum applications)

1. Disconnect the basic device 1 and the vacuum pump 7 from the mains power supply.
2. Connect the hose connection P of the solenoid valve 4 to the pump connection 2 at the rear of
the basic device via a connecting hose 3.
3. Connect the hose connection A of the solenoid valve 4 to the inlet of the vacuum pump 6 via
a connecting hose 5.
4. Insert the plug of the solenoid valve 9 into the provided socket 10 at the rear of the basic
device (connected mains voltage!).
5. Connect the basic device to the mains power supply 11.

Hint!
The vacuum pump is isolated from the device automatically before concentration is complete by
closing the solenoid valve which is piloted by the concentrator. The isolation can also be carried
out without a solenoid valve by closing an in-line valve manually (e.g., stop valve with a ground-in
stopper).
