Adjusting the thermostat knob to the left backstop does not mean permanent shutoff
of the heating element. When the heater is in use without blocking the daily rate, we do not
recommend the temperature to be set above 55°C. Select the "OPTIMUM" symbol
as the maximum.
4 IMPORTANT NOTICES

Without a confirmation of performed electrical installation issued by an authorised company,
-
the warranty certificate shall be void.
Check and exchange the Mg anode regularly.

Please make sure that for the connection of your heater you don't need an approval of the local
-
electricity supplier.
No stop valves can be put between the heater and the safety valve.
-
With overpressure in the water distribution system higher than 0.48 MPa, it is recommended
-
that a reduction valve is fitted before the safety valve.
All hot water outputs must have a combination faucet.
