GB
For this very reason, we recommend you connect this drain, leaving it always open, to
a drain pipe installed inclined continuously downwards and in a place without condensation.
Should the mains supply pressure be close to the maximum pressure value indicated
on the data plate, then a pressure reducing valve should be fitted as far away from the
appliance as possible. Should you decide to install the mixer assemblies (taps and
fittings or shower), make sure the piping is cleared of any impurities that could cause
damage.
Electrical connection
The appliance must be connected to the mains electricity supply by means of a differential
bipolar thermo-magnetic switch (30 mA) complying with the CEI-EN regulations in force
(contact break of at least 3 mm, even better if they are provided with fuses), or by means
of a plug.
Whenever the appliance needs to be disconnected from the mains electricity supply,
then use this switch to do so. The appliance is equipped with a H05VV-F cable with a
3x1,5mm cross-section, 8.5mm in diameter. The yellow-green earth wire must be
2
slightly longer than the phase wires. Before putting the appliance into operation, check
that the mains voltage conforms to the value on the appliance's data plate.
Putting into operation and testing
Before connecting the appliance to the electricity supply, fill the boiler up with water
from the mains supply. To do this, allow water to enter the appliance by opening the
main tap of your home system while at the same time turning a hot water tap on until
water comes out from it.
Check to see whether there are any water leaks from the flange (F fig.11). If there are
any, then tighten in moderation the corresponding fixing nuts (C fig. 10). Turn the
appliance on by pressing the switch.
Working temperature control
For those models not provided with external temperature control, the thermostat is on
a high setting. Should you wish to reduce the temperature, to limit consumption,
disconnect the appliance from the mains electricity supply, remove the small cap and,
using a screwdriver, turn the thermostat knob delicately clockwise (V fig. 7). On the
knob, references for the adjustment are indicated by a + and a - .

Maintenance instructions

A qualified professional must perform all maintenance and servicing operations.
Before calling on our Technical Assistance for a suspected failure, make sure that the
malfunction is not due to other causes such as, for example, the temporary lack of water
or of electricity.
The replacement of any spare parts
Disconnect the appliance from the mains electricity supply. Remove the cap to have
access to the electrical parts (fig. 8).
To act on the thermostat (T fig. 9), disconnect it from the supply cable and remove it
from its housing.
For any servicing of the heating element and anode, first of all empty the appliance of
its contents as follows:
