Always set up or install a plug for cleaning in the lower part of
the siphon in order to allow quick disassembly.
If the unit is not used during the winter period, the water contai-
ned in the system may freeze. All the water in the circuit must
be drained in good time. If draining the system seems too labo-
rious, a suitable quantity of antifreeze liquid can be mixed with
the water.
The unit is supplied as standard with left coil connections, howe-
ver, the coil can be rotated for the connections to be on the right.
The main and additional coil can be rotated after the unit is
installed, however, it is recommended to do so before the instal-
lation, with the unit resting on the ground.
Check that the voltage and the frequency of the electrical
system correspond to 230 V (±10%) single phase at 50 Hz;

for the maximum current required.
Make sure the electrical supply system complies with current
National safety regulations.
The connections must be implemented in accordance with the
diagrams supplied with the machine. Use an H05RN-F type,
