Checking flow rate
First you need to clean the filter balls. Shut the valve, undo the back of the valve, remove the strainer,
clean it and replace it then open the valve.
Start the pump, see above, the unit will be running in heating mode. Check the flow rate, we need
12l/min on the 5kW unit, 20l/min of flow on the 8kW unit and 30l/min on the 12 and 16kW unit. If
there is not enough flow the unit will never operate and it will give fault E911 see fault code page.
If you look into the flow meter you can see the flow in litres per minute. The flow rate is the low
figure, in this picture you can see a flow rate indicated, this shows 0l/min NOT 16l/min. Make sure
you clean the filter ball, turn up all the pumps, open all the valves and get rid of the air to keep flow
rate up.
