5.1   Language 

Select   

 

in the display with „OK“ and choose from GERMAN, ENGLISH and 

FRENCH by turning the Wheel Shuttle. Confirm the chosen language by pressing „OK“. The 
display gets back to the language request, but this time in the selected language. 

Turn the Wheel Shuttle clockwise or counterclockwise to continue the parametrization. 
 
 
 
 
 
 
 
 

5.2   Enter Purge Volume    

Select  

 

in the display using „OK“. Purge volume range is from 5 ltr. to 50.000 

ltr. and can be adjusted in steps of 5 litres by turning the Wheel Shuttle. If you press „OK“ 
while turning the Wheel Shuttle the step size is 50 litres. Save the selected value by pressing 
„OK“. Factory presetting is 200 ltr. 

The display now shows the saved value: 

 

 

Confirm  the  displayed  value  by 

pressing „OK“ again. 

Turn the Wheel Shuttle clockwise or counterclockwise to continue the parametrization. 
 
 
 
 
 
 
 
 

5.3   Enter Switchpoint min. Pressure  

Select   

 

in the display using „OK“. The min. pressure range is from 0.8 mbar to 

25 mbar and can be adjusted in steps of 0.05 mbar by turning the Wheel Shuttle. If you press 
„OK“ while turning the Wheel Shuttle, the step size is 1 mbar. Save the selected value by 
pressing „OK“. Factory presetting is 0.9 mbar. 

The display now shows the saved value: 

 

 

Confirm  the  displayed  value  by 

pressing „OK“ again. 

Turn the Wheel Shuttle clockwise or counterclockwise to continue the parametrization.
