13.6 Water filter:
In the water filter of your device you will find resin (yellow particles in the filter) for ion-
exchange. During the exchange, this resin acts as an acid. This reduces the risk of
decalcification of your device.
The water filter in your device is black , however -
to increase the visibility of
the ion-exchange resin - here a white filter.
Working principle of the water filter
The ion-exchange resin in the water filter reacts with the Mg2+ and Ca2+ dissolved in the
water and can therefore reduce the built-up of calcium or magnesium carbonate deposits.
Lifetime of the water filter
The actiontime of the filter is depending on the water hardness of the used water and the
frequency of use of your device up to approx. one year.
Maintenance of the water filter
However, the filter may require servicing once a month depending upon the water
hardness of the used water and the frequency of use of your device. We recommend to
put the water filter into saturated salt water.
Instructions:
Fill a bowl which is capacious enough for the filter with water. Put ordinary table salt into
the water until the salt will no longer be dissolved, i. e. the water will be saturated with salt.
Put the filter now for one day in salted water, then the ion resin can renew itself and
continue to fulfil its function.
