All maintenance operations and service visits should be performed by a competent person (who have the
skills required by the applicable norms in force).
Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power failure.
The appliance must be emptied if it is to be left unused in premises subject to frost.
When necessary, empty the appliance as follows:
- disconnect the appliance from the electricity mains;
- turn off the domestic mains tap;
- turn on the hot water tap (wash basin or bathtub);
- open the drain valve B (fig. 2).
The electrical parts may be accessed by removing the cover.
• For models featuring a user interface of the type represented in figures 3 and 5:
To work on the electronic thermostat (Ref. T), disconnect the power supply cable (Ref. C) and the control panel wire
(Ref. Y). Next, remove it from its slot, taking care not to bend the sensor support rod (Ref. K) too much.
To work on the control panel (ref. W), disconnect the wire (Ref. Y) and loosen the screws.
• For models featuring a user interface of the type represented in figures 4 and 6:
To work on the sensor support rod (Ref. K), disconnect the wire (Ref. F) from 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 and P) and loosen the screws.
During reassembly, make sure that all components are put back in their original positions.
In order to work on the heating element and the anode, the appliance must first be emptied.
For models fitted with a surge protection flange, remove the nut (D, fig. 7) and remove the bracket fixing the flange in
place (S, fig. 7), then press the flange (F, fig. 7) inwards and remove it with a semicircular movement.
For other models, loosen the 5 bolts (C, fig. 8) and remove the flange (F, fig. 8). The heating element and anode are
attached to the flange. During reassembly, make sure that the flange gasket, the thermostat and the heating element
are put back in their original positions (fig. 7 and 8). We recommend the flange gasket (Z, fig. 9) is replaced every time
it is removed.

MAINTENANCE REGULATIONS (for competent persons)
!
WARNING! Follow the general warnings and the safety norms listed at the
beginning of the text and keep to all the instructions given under all circumstances.
Starting and testing the appliance
!
WARNING! Disconnect the appliance from the electricity supply before
carrying out any work on it.
If the appliance is supplied with a power supply cable, should the latter need replacing, use a cable featuring the same
characteristics (type H05VV-F 3x1.5 mm
2
, 8.5 mm in diameter. The power supply cable (type HO5 V V-F 3x1.5, diameter
8.5 mm) should be threaded through the relevant hole on the rear part of the appliance until it reaches the terminal
board (M, fig. 3-4-5-6), then the individual wires should be fixed in place by tightening the corresponding screws. To
disconnect the unit from the electrical supply use a bipolar, switch conforming to CEI-EN standards (contact opening
at least 3 mm, better if equipped with fuses).
The appliance must be earthed and the earth cable (which must be yellow-green and longer than that of the phases)
is fixed to the terminal marked by the symbol (G fig. 3-4-5-6). Block the power supply cord on the small cap using
the special wire clamp provided. Before starting the appliance, make sure that the power supply voltage conforms to
the value indicated on the data plate. If the appliance is not supplied with a power supply cable, choose one of the
following installation modes:
- permanent connection to the mains using a rigid pipe (if the appliance is not supplied with a cable clamp);
- with a flexible cable (type H05VV-F 3x1.5mm
2
, 8.5 mm in diameter) if the appliance is supplied with a cable clamp.
Before powering the appliance, fill the tank up with mains water.
The filling is carried out by turning on the domestic mains tap and the hot water tap, until the air is completely released.
Visually check for water leaks from the flange and slightly tighten it, if necessary.
Power the appliance at the switch.
