Installation diagram:
Using a multi-function valve (MFV):
Dosing, pressure retention and overpressure valves (pos. 1 and pos. 2) can be
replaced by a multifunction valve (MFV) (pos. 3) from our product range, which
combines all these functions. When using a multifunction valve, it is essential
to observe the corresponding instructions
When using a metering valve, metering spikes < 1.2 mPa (12 bar) may occur.
This means that the pump displays an error and stops.
Troubleshooting:
1. Check back-pressure!
2. Check all valves on the metering lines; it may be that a valve fitted in the metering
line is not opening correctly or may even be closed.
3. Check the system pressure, and reduce if necessary.
