Vacuson 40/60
7 Operation
7.1 Switching device on and off
Use the power switch "I/O", at the rear of the device, to switch the device on and off.
The standby is signalized by the LED status light at front of the device.
The device can be switched off at any time, irrespective of any procedure for device
switch-off.
7.2 Pump activation by pneumatic pedal
The included standard pneumatic pedal when pushed activates a switch in the Vacuson
pump, to switch the pump on and off. This is maintained by an air pillow.
After the device was switched on, the pneumatic pedal has to be pressed to activate the
pump and generate vacuum. Pressed again the pump is deactivated.
The pump can only be activated by the pedal. The last used state befor switch-off stays
active.
7.3 Variegate with Vario-AIR-Pedal
Handsfree regulation of the vacuum can be maintained by using the Vario-AIR-Pedal (op-
tional, Art-No. 4242). When pressed, the Vario-AIR-Pedal opens a valve and the vacuum is
reduced by forced ventilation of the pressure system. The more the pedal is pressed the
less vacuum can build up, hence the suction performace decreases.
If the suction performace is controlled by the Vario-AIR-Pedal, the Vacuum Controller on
the front side of the device ideally remains in maximal position.
The Vario-AIR-Pedal is normally used together with the pneumatic pedal.
7.4 Regulating suction process
The suction process is regulated by the Vacuum controller at the front side of the device.
Rotate clockwise:
Rotating anticlockwise:
Establishing airtightness of the suction system:
1. Turn Vacuum Controller anticlockwise all the way to the stop (equivalent to vacuum minimum).
2. Switch on mains switch (I/O) of the pump and press On/Off pedal shortly. Pump is running and building up vac-
uum.
3. Crimp suchtion tube to generate maximal air-tightness of the suction system.
4. Turn Vacuum Controler clockwise (equivalent to vacuum maximum).
5. Wait for maximum build up of vacuum (equivalent to ≥ – 0.9 bar).
6. Now by turning the Vacuum Controller the suction performance can be regulated steplessly from 0 to – 0.9 bar.
Operating Instructions, Vacuson 40/60, Ref. 31997, V43/13
Vacuum increases, suction performance is enhanced.
Vacuum decreases, suction performance is reduced.
