3. Safety instructions
Installation, initial operation and maintenance of this appliance must only be conducted by an authorised professional, who will then be
responsible for adherence to applicable standards and installation regulations. We assume no liability for any damages caused by failure
to observe these instructions.
• Do not use the appliance until it has been correctly installed and unless it is in perfect working order.
• The appliance is suitable but not limited to domestic use and similar applications inside closed, frost-free rooms, and must only be
used to heat potable water from mains supply.
• The appliance must never be exposed to frost.
• The appliance must be earthed at all times.
• The minimal specific water resistance must not fall below the value stated on the label.
• The maximum water pressure must not exceed the value on the label.
• Before commissioning for the first time and each time the appliance is emptied (e.g. due to work on the plumbing system, if there is a
risk of freezing or in case of maintenance), the appliance must be vented correctly in accordance with the instructions in this manual.
• Do not remove the front cover under any circumstances before switching off the mains electrical supply to the unit.
• Never make technical modifications, either to the appliance itself or the electrical leads and water pipes.
• Pay attention to the fact that water temperatures in excess of approx. 43 °C are perceived as hot, especially by children, and may
cause a feeling of burning. Please note that the fittings and taps may be very hot when the appliance has been in use for some time.
• Water inlet temperature must not exceed 70 °C.
• In case of malfunction, disconnect the fuses immediately. In case of leaks, cut off the cold water supply instantly. Repairs must only be
carried out by the customer service department or an authorised professional.
• This appliance must not be used by any person (including children) with limited physical, sensorial or mental abilities or failing experience and/or knowledge unless they are supervised by a person responsible for their safety or received instructions about how to use
the appliance. Children should be supervised in order to make sure that they do not play with the appliance.
