6.1.2. Electric supply
The machine is supplied ready for connection
according to the required electrical specifications.
Before connecting the machine ensure that the
plate details (fig. 1) comply with those of the electric
distribution network.
The electrical connection cable must be directly
connected to the connection provided according to
current legislation. Ensure that the earthing system
is efficient and in compliance with current legal re-
quirements.
The earthing system and the lightening protection
system must be realized in accordance with the
provisions of current legislation.
For the supply network use a cable in compliance
with standards with protective conductor (earthing
wire).
For three-phase power use a cable with 5 conduc-
tors ( 3 n earth).
For single phase power supply use a cable with 3
conductors (phase + n earth).
In both cases it is necessary to provide an auto-
matic differential switch (Fig. 6) at the start of the
power cable, complete with magnetic release ele-
ments in accordance with the identification plate
details (Fig. 1). The contact opening must be
equivalent or over 3 mm.
Remember that each machine must be fitted with
its own safety elements.
WARNING:
Should the power supply cable be damaged
it is to be replaced by the manufacturer or by
its technical assistance service or by person
with equivalent qualification, in order to pre-
vent any risks.

6.2. Preliminary operations
ANTISUCTION VALVE INSTALLATION
On the top of the boiler there is the antisuction valve.
When installing the machine make sure to remove
the plastic fork “A” and check that the pin ”B” is
not blocked.
This operation is very important for the correct working
of the machine.
