The exact dosage is dependent upon:
viscosity of the detergent
height from which it is being drawn into the
unit
flow resistance in the high-pressure line
If an exact dosage is required, the amount of
detergent drawn into the unit must be measured
separately (e.g. by drawing the detergent out of
a measuring beaker).
Recommendations concerning detergents can
be found in the "Accessories" section.
