This shows the current pressure difference between the feed water and filtered water.
To show the pressure difference:
1. Select the menu Operating Data? Filter State.
2. Use and
to display Diff. Pressure and select it with
The display shows the pressure difference.
NOTICE The maximum pressure difference may not exceed 2.5 bar (36.26 psi).
A filter should reduce the pressure as little as possible. Therefore a high pressure difference is an indication that the filter is fouled (or the current water consumption exceeds the UrSpring capacity) and should be flushed see Flushing the filter module. If flushing does not reduce the pressure difference sufficiently, the filter should be changed see Change a filter module.
