Commissioning instructions
for the Winterhalter DuoMatik 3 softener
These regulations are intended for correct commissioning of the
softener by an authorised Winterhalter service technician.
1 Testing installation
 Test the following points:

Is it installed according to the operating instructions and the
connection diagram?

Is the water inlet temperature in accordance with the connec-
tion diagram?

Are the water pressures in accordance with the connection
diagram?
2 Converting total hardness
Water hardness is specified in the German degree of hardness (°dH)
in these instructions. Other units of measurement are used in other
countries.
 Measure the total hardness and convert into the German degree
of hardness (°dH) using the following table:
°dH °e °TH mmol/l
German hardness 1°dH= 1.0 1.253 1.78 0.179
English hardness 1°e= 0.798 1.0 1.43 0.142
French hardness 1°TH= 0.560 0.702 1.0 0.1
mmol/l 1mmol/l= 5.6 7.02 10.00 1.0
3 Adjusting and installing the brine valve
 Determine the total hardness of the
raw water:
 Total hardness ≤ 40 °dH:
 Use standard setting (5 mm).
 Total hardness > 40 °dH:
 Change distance (a) to 17 mm.
INFO
The salt consumption per
regeneration increases
from 0.3 kg to 0.5 kg.
 Ensure that the valve base (1) is
sitting in the recess of the container
base and that it is possible to move
the float cup vertically approx. 6 mm.
 Fasten riser pipe of the brine valve
onto the control head using the en-
closed screw connections (2).
4 Adding regeneration salt
Caution
Possibility of damage due to incorrect salt.
Only use undenaturated evaporated salt (approx. 15 mm
granularity or in tablet form) marked as regeneration salt
for softeners. Do not use any other types of salt e.g.
table salt, rock salt or de-icing salt. These may contain
components that are not soluble in water.
5 Venting / manually triggering regeneration
 Switch off the warewasher connected to the softener.
 Slowly open the water inlet to the softener.
 Turn the screw (1) slowly in a clockwise direction until the
regeneration begins (approx. 1 o'clock / 7 o'clock position).
 Air and water must be emitted from the hose with regenera-
tion waste water.
 After approx. 10 minutes no more water may be emitted
from the hose.
 Turn screw (1) further clockwise into the 7 o'clock (or 1 o'clock)
position and vent the second cartridge in the same way.
