REPLACING PARTS (WHEN NECESSARY)

Remove the plastic housing to access the electrical equipment (Fig. 7). lntervene on the power board
(Ref. M) by disconnecting the cables (Ref. C, P) and remove the screws. lntervene on the control panel
by first removing the power board. The display board is attached to the product through two fixing side
flaps (Fig. 4a Ref. A) accessible from inside the lower cover.
Release the control panel fixing flaps using a flat screwdriver to pry upon the same (Fig. 4b) and release
them from the pins, simultaneously push it outwards to free it from the seat. Repeat for both fixing flaps.
Pay special attention not to damage the plastic flaps as breaking them will not allow for correct assembly
of the panel in its seat, resulting in possible aesthetic defects. After removing the control panel, you can
disconnect the connectors of the rod carrying sensors and power board. To access the sensor mounting
rods (Fig. 7, Rif. K) disconnect the cables and remove them from their seats, taking care not to bend them
too much. When reassembling these parts, make sure that all the components are put back in their original
positions. The model have two dry resistances, which can be replaced without emptying the device, because
they are not in direct contact with water.
To replace a malfunctioning heating element (identified with a tester) disconnect the cable (Fig. 4c, Rif. X)
and undo the screw (Fig. 4c, Rif. V). Remove the damaged heating element and replace it.
To access the anodes, first empty out the appliance. Undo the bolts (Fig. 5, Rif. C) and remove the flang-
es (Fig. 5, Rif. F). The flanges are associated with both heating elements and anodes. During reassembly,
make sure that the sensor mounting rods and heating elements are restored to their original positions
(Fig. 7 and 5). Make sure that the flange plate marked H.E.1 or H.E.2 is installed in the position marked in
the same way. Replace the flange gasket every time you reassemble the flange (Fig. 6, Rif. Z).
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 Rif. R) 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 dam-
aging the heating element.
The magnesium anodes (Fig. 6 Rif. N) 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 (Fig. 5 Rif. x) is inspected in the event of fault due to its obstruction. To inspect it remove the
two rings (Fig. 5 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.
