8.1 What to do if...
...there are aluminium components in the system?
For aluminum components in water-bearing systems, manufacturers usually specify a maximum pH of 8.5.
However, it is known that aluminum components can remain stable even at a higher pH, insofar as the molar
concentration in the water is low. If an elector is installed in a system with aluminum components, the filling
and make-up water of the system must be treated by means of deionization. The system water should have a
conductivity of <10 μS/cm. Nevertheless, a pH of> 8.5 can occur. Regarding receipt of any warranty claims,
we refer to corresponding manufacturer‘s specifications.
...there is an unusually high oxygen ingress?
Please check that the expansion vessels are fine. If a 4-way mixing valve is used most attention has to be paid
to proper pressure maintenance to avoid an unnecessary oxygen ingress.
...the system water is still not clear one year after installation of the elector?
If single system parts are throttled so that only insufficient circulation takes places the cleaning of the water
by function of the elector cannot work. All system parts have to be opened completely when retrofitting an old
system. If this is not possible, all parts have to be flushed properly.
...no water comes out of the elector during flushing the device?
If the flushing water does not leak out of the elector the lower outlet is blocked. In this case please insert
carefully a strong wire into the opened lower valve to remove the blockage. CAUTION! Sudden leakage of a large
amount of hot water from the elector is possible. Protect yourself and supply a suitable bucket to collect the
water below the elector.
...water leaks out of the elector?
If water is dripping out of the insulation of the elector, usually the automatic air vent is broken. This part needs
to be replaced in this case.
...the water meter is not turning?
Check that the pumps are in operation and that all valves are opened. If the water meter still does not work
remove it together with the automatic regulation valve and clean both parts. Please replace the water meter with
a new one if cleaning does not help.
...the function meter does not work even though there is a new anode?
Check the indicator with a battery. If it shows no reaction you need to replace it with a new one. If the indicator
shows reaction there is possibly no water in the elector or the anode has not been installed correctly - possibly
the anode is covered with an oxide layer. The anode has to be cleaned with a brass wire brush in this case.
...Corrosion and appearance of sludge take place despite elector?
Please check first if the elector has been selected properly after our specifications and has been installed so that
a water flow takes place. Contact us an arrange for a water analysis for troubleshooting.
8.2 Control of Succss
To verify that a corrosion protection is established by the elector you can check that by control of certain
water parameters. Simply analyse the heating water once a year on pH, conductivity, hardness and
dissolved metals and you will get a long-term statistics from which you can learn the improvement of the
water quality and the corrosion related values. The regular water analysis also serves as a warning notice,
if trouble should arise.
