MAINTENANCE (FOR QUALIFIED PERSONNEL)
All interventions and maintenance operations must be carried out by qualified personnel(in possession of
qualification required by the regulations in force on the subject).
Before calling your Technical Servicing Centre, check that the fault is not due to lack of water or power
failure
WARNING: DISCONNECT THE APPLIANCE FROM THE MAINS BEFORE CONDUCTING ANY MAINTE-
NANCE WORK.
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 tap, if installed (Fig. 1, Ref. D), otherwise the central tap domestic power supply;
- turn on the hot water tap (wash basin or bathtub);
- open the drain valve (Fig. 1, Ref.B).
REPLACING PARTS (WHEN NECESSARY)
Remove the enclosure to access the electrical equipment.
To work on the electronic thermostat (Fig. 6, Ref. T) disconnecting the power cable (Fig. 6, Ref. C) and the
cable (Fig. 6, Ref. Y) of the control panel. Then remove it from its seat, taking care not to bend the sensor
holder rod excessively (Fig. 6, Ref. K).
To replace the electronic boardl (Fig. 6, Ref. W) disconnect the cable (Fig. 6, Ref. Y) and unscrew the
screws.
During reassembly, make sure that all components are put back in their original positions.
n order to work on the heating element and the anode, the appliance must first be emptied.
Undo the 4 bolts (A Fig. 4) and remove the flange. 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. We recommend replacing the flange gasket (Z Fig. 5).
Use only original parts from authorized service centres authorized by the manufacturer.
PERIODICAL MAINTENANCE
The heating element (Fig. 5, Rif.R) should be de scaled 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 de scaler (in this case please
read the safety data sheets of de scaling), you can simply break off the deposit, taking care not to damage the
heating element's cladding. The magnesium anode (Fig. 5, Rif.N) must be replaced every two years, other-
wise the decay of the warranty. 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.
