absorbed by the water heater (please refer to the data plate) and that the cross-
section of the electrical connection cables is suitable, and no less than 1.5 mm
The power supply cable (type H05 W-F 3x1.5, 8.5 mm in diameter) should be inserted
in the corresponding hole (X fig. 6) situated in the vicinity of the control knob and feed
it until it reaches the thermostat slots (T fig. 6). The electrical connection should be
made directly on the terminals (D fig. 6) of the thermostat (respect the L-N polarity).
The appliance is fitted with a cable and plug. For installations without a plug, use a
bipolar switch in conformity with the applicable norms in force (fused with a minimum
contact opening of 3 mm).
The appliance must be earthed and the earth wire (yellow-green colour) should be
fastened to the special faston on the heating element and marked with the

!
The use of multiplugs, extensions or adaptors is strictly prohibited.
It is strictly forbidden to use the piping from the plumbing, heating and gas
systems for the appliance earthing connection.
The appliance is not protected against the effects caused by lightning.
Before turning the appliance on, make sure the supply voltage complies with the value
stated on the appliance data plate and that the appliance itself is filled with water.
If the appliance is not supplied with a power supply cable, make a fixed connection to
the mains using a rigid pipe or cable for permanent installation.
Starting and testing the appliance
Before powering the appliance, fill the tank up with mains water.
Set the knob (F fig. 6) to the desired position, plug the appliance into the socket or
switch the main switch to "ON".
Check the appliance operation until the end of the first heating cycle, indicated by the
relative pilot lamp turning off. During the heating phase, the water expansion could
cause some trickling from the tap: this is completely normal and does not mean the
tap is faulty. Do not screw the taps too tightly to prevent damaging their seals.
In the event of a malfunction, read the paragraph regarding the MAINTENANCE
REGULATIONS.
Adjusting the operating temperature
The temperature of the water can be selected on the knob (F fig. 6) and can be adjusted
from 40 to 80°C approximately.
We recommend you set the temperature of the water heater to 60°C to:
- reduce the formation of limescale;
- reduce heat dispersion;
- avoid the risk of bacteria proliferation.
Anti-freeze function
If the temperatures in the room where the appliance is installed can reach particularly
low values, set the knob (F fig. 6) to setting *.
The pilot lamp (A fig. 4) stays on during the heating phase.
