Water Pump - HAKO Scrubmaster B 120 R Service Booklet

8. Water pump

The water pump for supplying the operative units is connected at the central control unit
at A01.X11:4 + 11. It is operated via clocked voltage to convey different water quantities
for the six stages. The voltage values measured here depend on numerous factors; it is
therefore not possible to specify exact values. Decisive is that the voltage values differ
considerably from the lowest to the highest stage.
The measurement of the water quantity is the recommended method to check the water
supply.
