- the pressure difference over the filter is too high
B Status LED
- (LED continuously lights): system is in operation;
STANDBY
no filter cleaning
- (LED blinks at high frequency
CLEANING

The product has been designed to function without problems for
a long time with a minimum of maintenance. However, the oil/
water separator underneath the pressure reducing valve needs
to be checked regularly and, if necessary, drawn off.
Action
Check the oil/water separator underneath the
pressure reducing valve. Draw off if necessary.
