30 °C to 85 °C:
– Clean with hot water.
Set working pressure and flow rate
Pressure/quantity regulation of the pump unit
 Turn the regulation spindle in a clockwise direction:
Increase working pressure (MAX).
 Turn the regulation spindle in an anti-clockwise di-
rection: Reduce working pressure (MIN).
Pressure/ quantity regulation at the hand spray gun
 Set the working pressure/quantity regulation at the
pump unit to maximum quantity.
