If the water metre is not working or flow is not occurring despite taking the abovementioned points into account, it is necessary
to rinse the HWR. If an automatic control valve is used for flow regulation, particles can impact its function. In this case, the valve
must be opened and cleaned. Vertical installation of the water metre can help in order to protect against possible damages. In
certain cases, it may be necessary to remove, clean or replace the water metre.
7.2 Functional check - Anode function
You can check the function of the electrochemical water treatment using the analogue display. The system is self-regulating. In
case of water with high conductivity or a large quantity of dissolved oxygen, the electrochemical cells automatically works harder
than with water which is no longer reacting. Here, the flow strength (milliamperes - mA) on the display signalises how hard the
HWR is working.
The display allows the following interpretations:
The display indicator is between 10% and 100%.
This is the normal operating range. The lower the display, the less the
anode has to work.
The display indicator is always on 100%.
The anode is working hard. If the indicator stays in this position for more than
one heating season, then the HWR may be too small or the water
may contain too many aggressive substances.
Measures: Heating water analyses, speak to your consultant.
The indicator is always near the red area,
When the HWR is emptied, it sinks to “0”.
The anode does not need to work anymore, because the water is no longer
reacting.
Measures: Observe, heating water analysis where applicable
A few years after initial operation, the indicator falls to the
red area.
The anode has been used up.
Measures: Open the device and replace the anode.
The device shows
an absolutely constant value even when the HWR is emptied.
The functional display is faulty.
Measures: Replace the functional display.
