Before powering up the appliance, fill the heater with mains water. To do so, open the mains cock and the hot
water tap until all the air has been vented from the boiler. Check for leaks from the flanges, tighten down the
fittings (not too much!) if necessary.
Turn on the appliance with the switch.
MAINTENANCE (FOR QUALIFIED PERSONNEL)
Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power failure.
Caution: disconnect the appliance from the mains before conducting any maintenance work..
Emptying the appliance
To drain the appliance, proceed as follows:
- close the tap, if installed (Fig. 2, Ref. D), otherwise the central tap domestic power supply;
- turn on the hot water tap (wash basin or bathtub);
- open the drain valve (Fig. 2, Ref.B).
Replacing parts (when necessary)
The electrical parts may be accessed by removing the cover.
• For models featuring an user interface of the type represented in figure 3:
To work on the sensor support rod (Ref. K), disconnect the wire (Ref. F) form the P.C.B. and remove it from its
slot, taking care not to bend it too much.
To work on the control panel (Ref. W), disconnect the wire (Ref. Y) and loosen the screws.
To work on the power board (Ref. Z), disconnect the cables and wires (Ref. C, Y, F, H e P) and loosen the
screws.
To work on the heating element, loosen the screw (Fig.5, Ref.V) and remove it from its slot.
To work on the anode the appliance must first be emptied. Loosen the 5 bolts (Fig.5, Ref.C) and remove the
flange (Fig.5, Ref.F). The anode is attached to the flange (Fig.5, Ref.N). We recommended the flange gasket
(Fig.5, Ref.Z) is replaced every time it's removed.
• For models featuring an user interface of the type represented in figure 4:
To work on the sensor support rod (Ref. K), disconnect the wire (Ref. F) form the P.C.B. and remove it from its
slot, taking care not to bend it too much.
To work on the control panel (Ref. W), disconnect the wire (Ref. Y) and loosen the screws.
To work on the power board (Ref. Z), disconnect the cables and wires (Ref. C, Y, F, H e P) and loosen the
screws. To work on the anode the appliance must first be emptied. Loosen the 5 bolts (C fig.6) and remove the
flange (Fig.6, Ref.F). The anode is attached to the flange.
During reassembly, make sure that gasket, flange and heating element are put in their original positions (Fig.6-7).
We recommended the flange gasket (Fig.7, Ref.Z) is replaced every time it's removed.
During reassembly, make sure that all components are put back in their original positions.
Only use authentic spare parts from service centers authorized by the manufacturer.
Periodical maintenance
The magnesium anode (Fig. 5-7, Ref.N) must be replaced every two years, otherwise the decay of the warran-
ty. In the presence of aggressive or waters rich in chloride it is recommended to check the status of the anode
annually. To remove this, disassemble the heating element and unscrew from the support bracket.
• For models featuring a user interface as represented in figures 4.
The heating element (Fig. 7, Ref.R) should be descaled every two years (the frequency must be increased, if
water is very hard) to ensure it works properly. If you do not wish to use a liquid descaler (in this case please
read the safety data sheets of descaling), you can simply break off the deposit, taking care not to damage the
heating element's cladding.
