– Detergents simplify the cleaning task. They are sucked in
from an external detergent tank.
– The basic model of the appliance is equipped with a dosing
valve (C). A second dosing device (dosing valve D) can also
be procured as special accessory. It is then possible to use
two different detergents.
– The dosing quantity is set at the detergent dosing valves (C
or D) at the operating panel. The set value corresponds to the
percentage share of the detergent.
– The outer scale is applicable while using undiluted detergents
(100% CHEM).
– The inner scale is appliance while using 1 +3 pre-diluted de-
tergents (25 % CHEM + 75 % water).
The following table gives the detergent consumption for the val-
ues on the outer scale:
The exact dosing depends on:
– Viscosity of the detergent
– Suction height
– Flow resistance of the high pressure pipe
If an exact dosing is required, then measure hte detergent quan-
tity that is sucked in (for e.g. by sucking in from a measurement
beaker).
Note: For list of recommended detergents refer the chapter "Ac-
cessories".
Caution
There can be calcium deposits in the continuous heater if you use
the appliance without softeners.
If the softener tank is empty, the indicator lamp for protection
against calcification (H) begins to glow.
