Chapter 3 - Operation / Handling
3.1 General note
The guideline DIN EN 1717 will replace the DIN 1988-100. The „short-term connection“ of the heating system
with mains water supply by a hose connection is then not longer state of the art.
According to DIN EN 1717 chapter 5.3.2 : „All connections to the tap water installation are regarded as
permanent connections“.
Therefore we recommend to install a safety armature with fluid class 4 when filling a heating system with
CLARIMAX 1200 DM pH+ LED.
3.2 Comissioning
Starting with a new filter cartridge you always should displace air out of the water filter system and flush the
filter system.
Please proceed as follows:
1. Install filter cartridge in system, close system with filter-head and connect with hoses.
2. Position filter system horizontally and let water run into connection „IN“. Rinse the filter with 10 liters water.
3. Position the filter vertically and rinse with additional 10 liters of water.
4. Dispose the rinsing water.
The filter-system is ready for operation after this procedure.
Repeat this process after any cartridge change.
3.3 Filling of heating systems
As soon as the system is ready for operation you can fill the heating system as usual. The filter treats the water
in a single flow through principle. The inlet of CLARIMAX is to be connected to the mains tap water supply
and the outlet of CLARIMAX with the heating system. Once the water has passed CLARIMAX it has the quality
according to the guidelines. We recommend to install a system separator or a compact filling armature at the
inlet of the CLARIMAX filter system.
3.4 In-line water correction
You even can treat existing heating water with the CLARIMAX filter system. Simply install CLARIMAX in a
bypass and pump the heating water via CLARIMAX and back into the system, where the treated water will
dillute the circulating system water. As a temporary limited but continuous process all the heating water will be
corrected after a while. Please observe the maximum operation pressure and that the heating water should be
in a quality of natural water without chemicals. The water must not contain strong oxidants. Particles should be
removed by additional filtration at the inlet of CLARIMAX.
3.5 Capacity control
There is a conductivity meter installed in the filter head. This device controls the filter capacity and gives a
signal, as soon as the cartridge is exhausted and needs to be replaced.
The end of capacity is indicated by an electrical conductivity of the treated water at a level of 90 - 100 µS/cm.
