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.

You have to apply for approval of a local power supplier to connect the heater.

No stop valves can be put between the heater and the safety valve.

If the overpressure in the water main exceeds 0.48 MPa, a pressure control valve must be mounted

before the safety valve.

All hot water outputs must have a combination faucet.

Before filling the heater with water for the first time, it is recommended to fasten the flange

connection nuts of the tank.

It is not allowed to handle the thermostat, aside from temperature resetting with a control button.

All electric installation handling, adjustment and replacement of the regulation elements shall only

be performed by an authorised service company.

The thermal fuse must not be turned off! In case of thermostat defect, the thermal fuse interrupts

electric power input to the heating element if the water temperature in the heater exceeds 90 °C.

As an exception, the thermal fuse may also switch off due to water overheating caused by

overheating the hot water heating system boiler (in case of a combined heater).

We recommend you operate the heater with one type of energy.

Both the electric and water installation must follow and meet the requirements and

regulations relevant in the country of use!
