EMPTYING THE APPLIANCE
The appliance must be emptied if it is to be left unused for a long period and/or in premises subject to frost.
To drain the appliance, proceed as follows:
- disconnect the appliance from the electricity mains;
- close the cut-off valve, if installed (Fig. 2, Ref. D), or the main household water valve, if not;
- turn on the hot water tap (wash basin or bathtub);
- open the drain valve (Fig. 2, Ref.B).
REPLACEMENT OF PARTS WHEN NECESSARY
The electrical parts may be accessed by removing the cover (Fig. 7).
Intervene on the power board (Fig. 7, Ref. Z) by disconnecting the cables (Fig. 7, Ref. C,Y and P) and remove
the screws. Intervene on the controlpanel by f irst removing the power board (Fig. 7, Ref.Z).
The display board is secured to the product with 2 screws (Fig. 4, Ref. A). After loosening the screws,
press both the tabs with two fingers (Fig. 4, Ref. B) and remove the support (Fig. 4, Ref. C) from its hous-
ing, moving it towards the centre of the product.
After removing the control panel, you can disconnect the connectors of the rod carrying sensors and power
board. Intervene on the rod carrying sensors (Fig. 7, Ref. K) by disconnecting the wires (Fig. 7, Ref. F) from the
control panel and remove it from its seat, taking care not to excessively bend them.
During reassembly, make sure that all components are put back in their original positions.
To work on the heating elements and anodes, first drain the appliance.
Remove the bolts (Fig. 5, Ref. C) and remove the flanges (Fig. 5, Ref. F). The flanges are coupled to
the heating elements and anodes. During reassembly, make sure to restore the rod carrying sensors
and the heating elements to the original positions (Fig. 7 and 5). Make sure that the f lange plate with
the coloured writing H.E.1 or H.E.2, is mounted in its position marked by the same writing.
We recommend replacing the f lange gasket (Fig. 6, Ref. Z) every time it is disassembled.
CAUTION! Swapping the heating elements will cause the appliance to malfunction. Work on one element
at a time, and only disassemble the second one after the first one has been reinstalled.
Use only original parts from authorized service centres authorized by the manufacturer.
PERIODICAL MAINTENANCE
The heating element (Fig. 6, Rif.R) should be descaled every one years to ensure it works properly (the fre-
quency must be increased, if water is very hard). If you prefer not to use special liquids for this operation, simply
crumble away the lime deposit without damaging the heating element.
The magnesium anodes (Fig. 6, 6a Rif.N) must be replaced every two years or the warranty shall be voided
(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 them, remove the heating elements and unscrew them
from the brackets. The bypass pipe (Fig. 5, Rif. X) is inspected in the event of fault due to its obstruction. To
inspect it remove the two rings (Fig. 5, Rif. W).
After routine or extraordinary maintenance, 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.
SAFETY VALVE
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.
