Regenerating dosing
with condenser
The water softening can be adjusted in 10 levels. The incoming
water flows until positon 5 to 85 % through the softener which
works according to the ion exchange principle. The ion exchanger
is filled with small epoxy resin balls. The resins exchange the
hardness constituents (calcium and magnesium), for sodium
ions.
When all the sodium ions are used up, it is necessary to
regenerate the softener. This is done by flushing a brine solution
through the softener.
Afterwards the softener is washed out with fresh water and is now
fully effective.
Depending on the water hardness, regeneration is only necessary
after several wash cycles.
The remaining 15 % of water flow through the rinse tank ventilation
directly into the appliance.
From setting of level 6, the whole water flows through the
softener. For this purpose you also have to set mechanically from
0 to 1 with the regenerating dosing.
With the setting of level 9, it is additionally regenerated after the
washing in a rinse cycle. With the settings 1 to 8, it is regenerated
after the final rinse depending on need. The softening system is
designed for a water hardness of up to 70 °dH.
With every filling step, the condenser
cools down due to the cold incoming
water. Therefore another 1 liter of water
is required during the drying cycle.
