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
