3 IMPORTANT NOTICES

3.1 IMPORTANT NOTICES
- Check and exchange the Mg anode regularly.
- No stop valves can be put between the heater and 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
- Prior to startup you shall run the heating circuit and possible impurities, that are trapped in
the filter, to clean up. After that, the system is fully operational.
Do not try to repair the failure yourselves. Seek either expert or service help. It does not take
much for an expert to remove the defect. When making a repair appointment, report the
type and serial number you find on the performance plate of your water heater.
To prevent formation of bacteria (e.g. Legionella pneumophila) within stack heating it is
recommended, if absolutely necessary, to increase the temperature of HSW periodically for
a transitional period of time to at least 74°C. It is also possible to make use of another way of
HSW disinfecting.
