WARNING
NOTE
During filling, it might not be possible to remove all air in the system. Remaining air will be removed through the
automatic air purge valves during the first operating hours of the system. Topping up the water afterwards might be
required.
The water pressure will vary depending on the water temperature (higher pressure at higher water temperature).
However, at all times water pressure should remain above 0.3 bar to avoid air entering the circuit.
The unit might drain-off too much water through the pressure relief valve.
Water quality should be complied with EN 98/83 EC Directives.
Detailed water quality condition can be found in EN 98/83 EC Directives.
Connect the water supply to the filling valve and open the valve.
Make sure the automatic air purge valve is open (at least 2 turns).
Fill with water pressure of approximately 2.0 bar. Remove air in the circuit as much as possible using the air purge
valves. Air in the water circuit could lead to malfunction of the backup electric heater.
9.5 Filling water
Do not fasten the black plastic cover on
the vent valve at the topside of the unit
when the system is running. Open air
purge valve, turn anticlockWise at least
2 full turns to release air from the
system.
CounterclockWise rotation, remove the flow switch.
Drying the flow switch completely.
When the unit is not running for a long time, make sure the unit is powered on all the time. If you want to cut off the
power, the water in the system pipe needs to be drained clean to avoid the unit and pipeline system being damaged by
freezing. Also the power of the unit needs to be cut off after water in the system is drained off.
