4 IMPORTANT NOTICES
4.1 INSTALLATION REGULATIONS
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!
