Thermoelectric models
The instructions given in this manual also apply to thermoelectric models. However, such models must also be
connected to the radiator pipes. Connect the upper radiator connector of the water heater to the radiator's up pipe,
and the lower one to the down pipe, fitting two cocks at the same time.
The lower cock, which is easier to access, is used to disconnect the appliance from the circuit when the radiator is
not in use.
MAINTENANCE REGULATIONS (for competent person)

CAUTION Observe all general warnings and safety standards listed at the
beginning of this text in full; all such instructions are obligatory.
Maintenance work may only be done by qualified technicians (in possession of the regulatory requisites).
Before requesting for the Technical Assistance to intervene for a suspected fault, check that this is not caused by a
temporary lack of water supply or power failure.

Make sure to drain the appliance when it is out of service or in an area subject to subzero temperatures.
To drain the appliance, proceed as follows:
- permanently disconnect it from its power supply;
- close the cock, if present (
D fig. 1), or the main domestic water system cock;
- open the hot water tap (sink or bath tub);
- open cock (
B fig. 1).
Disconnect the appliance from its power supply.
Remove the enclosure to access the electrical equipment.
To work on the thermostat, extract it from its mount and disconnect it from its power supply.
To work on the heating element and anode, first drain the appliance.
Use only original spare parts
The heating element ( R fig. 5) should be descaled every two years to ensure it works properly.
If you do not wish to use a liquid descaler, you can simply break off the deposit, taking care not to damage the heating
element's cladding.
The magnesium anode (
N fig. 5) must be replaced every two years (this does not apply to appliances with stainless
steel boilers); however, the anode should be checked every year if the water is corrosive or chloride rich. To replace
it, remove the heating element and unscrew it from its bracket.
After routine or extraordinary maintenance, we recommend filling its tank with water and draining it completely
so as to remove any residual impurities.
Use only original spare parts supplied by the manufacturer's authorised service centres, otherwise the.
If the water overheats excessively, a thermal cutout (CEI-EN compliant) trips to cut the electrical power supply to the
heating element (both phases); contact the Service Centre if this occurs.
Regularly check that the overpressure device is not jammed or damaged; if it is, remove any scale or replace it.
If the device has a lever or knob, operate it to:
- drain the appliance, if necessary
- check its operation from time to time.
