MAINTENANCE REGULATIONS (for qualified personnel)

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.

WARNING: disconnect the appliance from the mains before conducting any maintenance 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 cut-off valve, if installed, or the main household water valve, if not;

- turn on the hot water tap (wash basin or bathtub);

- open the drain valve.

Replacing parts (when necessary)

Remove the plastic housing to access the electrical equipment.

The product is equipped with two dry heating elements (not in direct contact with the water) which,

therefore, can be replaced without emptying the appliance.

To replace a malfunctioning heating element disconnect the cable. Remove the damaged heating ele-

ment and replace it. To access the anodes, first empty out the appliance.

Undo the bolts and remove the flanges. Replace the flange gasket every time you reassemble the

flange.

CAUTION!

Use only original parts from authorized service centres authorized by the manufacturer.

Periodical maintenance

The heating element should be descaled every two years to ensure it works properly (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 must be replaced every two years (this does not apply to appliances with stain-

less 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.

After routine or extraordinary maintenance, - recommend filling its tank with water and draining it com-

pletely so as to remove any residual impurities. Use only original spare parts supplied by the manufac-

turer'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.
