Comments
•
If the unit is only used for warm water supply, the heating function can be switched
off using the service code on the operating panel. The CH installation does not need
to be connected or filled.
•
If the unit is switched off during winter, and is disconnected from the electricity
supply, the sanitary water must be drained in order to prevent freezing. To do so,
disconnect the tap water connections underneath the unit.
In case of old installations or domestic hot water circuits which can contain small particles,
install a filter in the domestic hot water circuit.
This pollution could cause a fault during domestic hot water operation.
