from metal residues. Make sure the filter
f the solenoid valve is clean (see section
5.2).
Connect the "Water" pipeline to water mains
and install a shut-off valve.
Ensure that the shut-off valve is positioned
so that it can be easily operted by the opera
-
tor at any time.
Warning: if the water supply pipe gets dam
-
aged, it should be replaced with a new one
while the old damaged one should not be
used again.
2.3 Electrical connection
The electrical system shall be fitted with an
efficient earthing system, as required by the
regulations in force. You can ensure the elec-
trical safety of the appliance only in the pres
-
ence of a compliant electrical system.
Before wiring, check the voltage and fre
-
quency of the power grid to ensure that they
comply with appliance rated values given on
the technical data plate (fig. 4).
For direct connection to the mains, you
should placed between the appliance and
the network a device, sized according to the
load, which ensures disconnection. Its con-
tacts should have a minimum opening distance that enables complete dis-
connection under the conditions of overvoltage category III, according to
installation rules; this device should also be located so that it can be easily
used by the operator at any time.
Turn the master switch, to which the power plug will be connected, to posi-
tion 0 (zero). Make the socket cable section checked by qualified staff to
make sure it suits the the power absorbed by the device.
Unscrew the screws that secure the back of the device and remove it (fig. 5).
The flexible cable should be made in polychloroprene or synthetic elastomer
and provided with an oil-resistant sheath.
Use a cable with a cross section suitable for the load of every device, as
shown in table (tab. 1).
