4.2 Maintenance instructions
4.2.1 Calibrating the pressure sensors
Calibration of the pressure sensors may be required from time to time or when the UrSpring
shows a sensor error (error code 109). Calibration adjusts the zero
​
point of the pressure
sensors to atmospheric pressure. During the calibration process, there may not be any
pressure, flow or vibrations. The control unit adjusts the pressure sensors using the atmospheric
pressure.
To perform a calibration:
1. Close the feed water valve.
2. Close the filtered water line downstream.
3. Flush the UrSpring manually as described in
​
Flushing the filter module
​
.
The UrSpring is now at atmospheric pressure.
4. Go to menu
​
Change Settings? >
​
Calibrate Now? .
The display shows: ​ Disconnect Water ”.
5. Push to confirm the water is disconnected.
The controller calibrates the sensors.
When finished the display shows:
Adjustment or Sensors o.k.!
NOTICE When controller display shows a sensor error, and you are sure that during the
calibration there was no pressure, flow or vibration, then the pressure sensors must be
exchanged (see
​ 4.2.2 Exchanging the pressure sensors ​ ).
4.2.2 Removing the controller from the valve block
To maintain the sensors on the valve block you need to remove the controller from the valve
block:
1. Close the water in feed and filtered water lines.
2. Depressurize the UrSpring with a manual flush (see
​ Flushing the filter module ​ ).
3. Disconnect the power by removing the plug from the mains socket.
4. Remove the four screws on the sides of the controller.
5. Carefully lift the controller from the valve block.
