sible flow rate with a fully opened tap (see chapter "Specifi-
cation/ Data table").
If necessary reduce the flow rate at the butterfly valve of the
safety valve.
Turn the temperature selector to maximum.
Switch the mains power ON.
Check the function of the appliance. Ensure that the tempera-
ture controller switches off.
Check that the safety valve is working correctly.
11.1.1 Appliance handover

users and familiarise them with their operation.
Make the user aware of potential dangers, especially the risk
of scalding.
Hand over these instructions.
