Water filter system for deionization

4.5.3 Notes on the ion exchanger mixed bed resin

Only use resin that is suitable treating the top-up or filling water for heating systems. The ion
exchange resin should have a proportion of the anion resin of at least 60%.
If the water filter system has not been used for a long period of time, rinse twice with a volume of
water corresponding to the volume of the cartridge before using it again.
To avoid contamination, we recommend an annual resin change.

4.6 Capacity monitoring with the MINIgarde conductivity indicator

MINIgarde is a flashing conductivity indicator that has three LEDs.
Green LED flashes = <10 μS / cm conductivity = filter has full capacity.
Yellow LED flashes = 10 - 50 μS / cm conductivity = filter shows exhaustion.
Red LED flashes => 50 μS / cm conductivity = replace resin in any case.
Note: Ideally, the reading of the capacity takes place while water is flowing. If necessary, open the
sampling valve to create a water flow.
MINIgarde has an integrated battery with a lifespan of 10 years. The entire measuring device must be
replaced at the end of its service life.

4.7 Maintenance instructions

Apart from the capacity control and the regular resin change, only little maintenance is necessary.
However, please note the following information.

4.7.1 Safety sieves in the connection fitting for wall-hanging cartridges

A safety sieve is installed in the inlet and outlet of the black connection fitting. This sieve prevents the
mixed bed resin from breaking through if the cartridge is installed without the riser pipe, the riser pipe
is defective or a suction effect occurs.
To clean or replace the safety sieves, you must unscrew the black double nipples from the connection
fitting.
A reduced flow rate can be an indication that the safety sieves are contaminated and need to be
cleaned or replaced.

4.8 Disposal

The mixed resin ion exchanger can be disposed of with normal household waste.
The water filter system must be disposed of in accordance with local regulations.
