The heating system must be completely filled with water. If necessary top up with water.
Whilst filling the heating system, keep the shut-off valves open and check the system
pressure at the control unit housing. The system pressure must lie inside the green
marking. The connection between the tap water and heating water required for filling
must be removed after the fill has been completed. Otherwise there is a risk that your
tap water will be contaminated by heating water.
The system may overheat if the boiler is operated without water.
NOTE
Inhibitors are not permissible as there is a risk of damage to the boiler.
The siphon must be fitted and filled.
