Replacing parts

Disconnect the appliance from its power supply.

Remove the enclosure to access the electrical equipment.

To work on the thermostat, extract it from its mount and disconnect it from its power supply.

To work on the heating element and anode, first drain the appliance.

Use only original spare parts

Scheduled maintenance

The heating element (R fig. 5) should be descaled every two years to ensure it works properly.

If you do not wish to use a liquid descaler, you can simply break off the deposit, taking care not to damage the heating

element's cladding.

The magnesium anode (N fig. 5) must be replaced every two years; however, the anode should be checked every year

if the water is corrosive or chloride rich. To replace it, remove the heating element and unscrew it from its bracket.

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.

Reactivating the two-pole cutout

If the water overheats excessively, a thermal cutout (CEI-EN compliant) trips to cut the electrical power supply to the

heating element (both phases); contact the Service Centre if this occurs.

USER INSTRUCTIONS

CAUTION Observe all general warnings and safety standards listed at the

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

Recommendations

- Do not place anything under the water heater which may be damaged by a leak.

- If the water is not used for a long time:

➣

shut off power to the appliance by setting the external switch to "OFF";

➣

close the water circuit cocks.

- Water heated to over 50°C can cause immediate serious burns or even death. Children, disabled persons and the

aged are particularly at risk of burns.

Do not attempt to service or repair the appliance.

Operation, setting the operating temperature

Start up

Power up by turning the adjustment knob clockwise. The indicator lamp only remains on when heating up. The thermostat

will automatically disconnect the resistance when the preset operating temperature is reached.

Setting the operating temperature

On models with external regulation, the water temperature can be set with the knob (M fig. 6) connected to the

thermostat, as indicated on the device itself.

USEFUL HINTS

If the water delivery is cold, have the following checked:

- is there power to the thermostat and terminal block?

- are the heating elements working?

If the water is boiling hot (steam is coming out of the taps)

Shut off electrical power to the appliance and have the following checked:

- thermostat;

- the amount of scale on the boiler and heating element.

If the hot water delivery is insufficient, have the following checked:

- the mains water pressure;

- the condition of the deflector on the cold water intake pipe;
