8. Troubleshooting
8.1 What you should do if...
...there are aluminium components in the system?
For aluminium components in water bearing systems, most manufacturers state a maximum pH value of 8.5. However, it is
known that aluminium components can remain stable at higher pH values, as long as the concentration of the substance s in the
water remain low. If a regulator is installed in a system containing aluminium components, the filling and make-up water of the
system must be prepared using total water demineralisation. However, it may adjust to a pH value of >8.5. With regards to com-
plying with any guarantee claims, we refer to the relevant manufacturer's specifications.
... the system water is still not clear after one year of operating the HWR?
If the throughflow is strongly limited due to individual system parts, causing insufficient circulation, the HWR’s cleaning function
won’t work. All system parts must be fully opened as far as possible. If this is not possible, then all the parts must be rinsed
properly.
...that no water leaks when rinsing the Heating Water Regulator?
If no water is coming out during rinsing, then the lower outlet is blocked. In this case, carefully pierce the opened outlet and loo-
sen the blockage. CAUTION!! Here a large quantity of water may suddenly come out. Set up suitable collection vessels.
...water is leaking from the HWR?
If the water is dripping from the insulation, the automatic quick bleeder is faulty. In this case, it needs to be replaced.
...the water metre is not turning?
Check if the pumps are working and all the valves are open. If the water metre is still not turning, remove both the metre and
the automatic control valve and clean them. If the water metre is still not working after this, then it needs to be replaced.
...the functional display is still not reacting even though a new anode has been installed?
Test the display using a 1.5V battery. If it does not show any reaction, install a new display. However if it reacts, then there may
not be any water in the device or the anode is not installed properly, possibly there is an oxide layer on the anode. This will need
to be cleaned using a brass wire brush.
...corrosion and silt build-up occur despite HWR use?
Please check if the regulator has been laid out according to our instructions and has been installed correctly so that water
throughflow takes place. Has the maintenance been carried out as described above? Contact us and arrange a water analysis for
troubleshooting.
8.2 Success monitoring
If you would like to check if the HWR plus is really providing corrosion protection,
you can check this by means of certain water parameters. Simply have the heating water
analysed once a year for pH value, conductivity, hardness and dissolved metals. This will provide you with a long-term statistic
and you can determine the corrosion protection function by means of the improved values. The regular water analysis also serves
as a warning system if problems occur.
