3. Assembly
When the softener is supplied packed up, at first it
has to be made ready for connection:
-Remove softener from the cardboard
box and remove cardboard pads from
the plastic container.
-Connect brine suction pipe and regene-
rating drain hose at the control head.
-Fix water inlet and outlet connections
together with the safety combination at
the control head.
-Attach the temperature registration label
to the pipe bend of the water inlet.
The appliance consists of a mobile plastic container
with removable cover. Into the container which
contains regenerating salt and brine there are built in
two cartridges made of glass fiber reinforced
polyster, which are connected to each other and
filled with exchanger resin. One of the cartridges is
equipped with a control head with exchangeable
hardness section plate. In the plastic container there
is also the brine suction pipe with integrated float
valve.
Water inlet and drain are at the rear of the control head. The water inlet is equipped with a safety combination
according to DIN DVGW 1988.
4. Function
The treatment of the water is done according to the principle of ion exchange. The exchanger resin in the
cartridges has the property to bind the hardness forming salt ions from the passing untreated water and to give to
the water other non-hardening salt ions.
The exchange resin has a limited capacity which depends on the hardness of the untreated water. When
exhausted, it has to be regenerated.
In order to have continuously softened water, in case of exhaustion one of the cartridges the DuoMatik 2x4
automatically switches to the second cartridge and the exhausted cartridge is regenerated.
The regeneration intervals are controlled by the hardness section disc, which has to be adjusted to the hardness
of the untreated water.
