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.

(model with interface shown in Fig.8c)

The electrical parts may be accessed by removing the cover (

Fig. 7a

).

To operate on the thermostats, you will first need to disconnect them from the cables (

Fig. 7a Ref. K 

and L

) and remove them from their housings.

To access the anodes, first empty out the appliance.
Undo the bolts (

Fig. 5a, Ref. C

) and remove the flanges (

Fig. 5a, Ref. F

). The flanges are associated with 

both heating elements and anodes. Replace the flange gasket every time you reassemble the flange 
(

Fig. 6a, Ref. Z

).

When reassembling these parts, make sure that all the components are put back in their original posi-
tions.

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, 6a Rif.R

) should be descaled every one years to ensure it works properly (the 

frequency 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 applianc-

es 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, 5a Rif. X

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

the two rings (

Fig. 5, 5a 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.

RESETTING THE BIPOLAR SAFETY DEVICE 

(model with the interface shown in Fig. 8c)

In the event of abnormal water overheating, a thermal safety switch (in compliance with the national reg-
ulations) cuts off the electrical circuit on both power supply phases of the heating element; if this occurs, 
contact the Technical Assistance Service.
