  Check mains pressure 

  Check the plug connection of sensor plug and pressure sensor 

 

 

WARNING 

Do not remove the pressure sensor under any 
circumstances. Sensor is located directly in the pressure 
range of the water. Water with high pressure could escape. 

 

  Check  if  water  has  been  used  for  a  long  period  without 

interruption. 

 

If a longer permanent flow duration is required, the system can be 
specifically  adapted  to  your  application  (please  refer  to  chapter 
9.1.5 "Changing the flow duration"). 

 

If no prolonged water withdrawal is known, the piping system must 
be tested for tightness (see chapter 8.2 "Checking the tightness").
