Water Pump - HAKO Scrubmaster B 260 R Service Booklet

8. Water pump

The water pump for supplying the operative units is connected at the central control unit
at A01.X12:1 + 11. It is operated via a clocked voltage to deliver different quantities of
water for the stages. The voltage values measured here depend on numerous factors; it
is therefore not possible to specify exact values. It is decisive that the voltage values
differ considerably from the lowest to the highest stage.
Checking of the actual water quantities is preferable.
During the voltage measurement it must be taken into consideration whether the
dependence of the water quantity on the travel speed has been activated. This can be
activated by the operator in menu item "Maintenance". The values measured with this
setting can easily be misinterpreted.
