- connection to mains with a rigid pipe (if the appliance has no cable clamp); use a cable with a minimum 3x1.5 

mm

 section;

- with a flexible cable (type H05VV-F 3x1.5mm

2

, 8.5 mm in diameter) if the appliance is supplied with a cable 

clamp.

Startup and commissioning 

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 water leaks from the flanges, from the by-pass pipe, tighten down the bolts not too much, if necessary (

C

Fig. 5) and/or the rings (

W

 Fig. 7).

Power the appliance by actuating the switch.

MAINTENANCE REGULATIONS (for competent person) 

CAUTION Observe all general warnings and safety standards listed at the begin-

ning of this text in full; all such instructions are obligatory.  

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. 

Emptying the appliance 

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

 (fig. 2). 

Replacing parts 

Remove the plastic cover in order to work on the electrical parts (fig. 7).

To work on the door-sensor rods (Ref. 

K

) it is necessary to disconnect the wires (Ref. 

F

) from the circuit board 

and pull them from their seating making sure that you do not bend them excessively.

To work on the power board (Ref. 

Z

) disconnect the wires (Ref. 

C

, 

Y

, 

F

 and 

P

) and loosen the screws.

To work on the control panel refer to figure 4. Remove the plastic cover (fig. 4A), loosen the 4 front screws 

(fig. 4B), disconnect the wire (fig. 4C), and loosen the 4 rear screws (fig. 4D).

During reassembly, make sure that all components are put back in their original positions. To work on the 

heating elements and the anodes, it is necessary to first empty the appliance.

Unscrew the bolts (

C

 fig. 5) and remove the flanges (

F

 fig. 5). The flanges are coupled with the heating 

elements and the anodes. During reassembly make sure the thermostat sensors and the heating elements 

are put back in their original positions (fig. 7). Make sure that the flange plate colour marked H.E.1 or H.E.2, 

is assembled on the water heater marked with the same colour code. We recommend the flange gasket (

Z

fig. 6) is replaced every time it is removed.

Warning! The inversion of the heating elements will cause the appliance to malfunction. Work on one 

heating element at a time and disassemble the second one only alter having reassembled the first 

one.

Periodical maintenance 

The heating element (

R

 fig. 6) should be descaled every two years to ensure it works properly (

R

 Fig. 6) 

approximately every two years (the frequency must be increased, if water is very hard).

If you pre- fer not to use special liquids for this operation, simply crumble away the lime deposit without 

damaging the heating element.

The magnesium anodes (

N

 Fig. 6) 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 them, remove the heating elements and unscrew them from the brackets.

The bypass pipe (

X

 Fig. 7) is inspected in the event of fault due to its obstruction. To inspect it remove the 

two rings (

W

 Fig. 7).

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.
