INSTALLATION
During installation, carry out proper machine levelling, which is a prerequisite
for a correct operation thereof (max. tolerance 2°).
In order to prevent any damage caused by steam going out of the machine,
make sure that the surrounding materials do not deteriorate in its presence.
After machine installation check thermostat settings, booster 85°C, tank 60°C.
1)ELECTRICAL CONNECTION
The electrical safety of this equipment is only assured if it is connected as
follows. It is necessary to connect the equipment to an effective earthing as
specified by the electrical safety regulations in force. Check that this basic
requirement is complied with, in case of any doubt ask for a careful check of
the installation by a qualified personnel. In the case the earthing is not efficient
there will be a dispersion due to the suppresser.
The machine shall be included in a correctly dimensioned equipotential, whose
effectiveness is to be very tight in accordance to the procedures set for in the
applicable safety standards. The connection shall be performed through a
screw marked by the plate near the rear side of the appliance.
The manufacturer declines any responsibility for any damages caused by lack
of an effective ground installation. For the electrical power supply have
available a wall circuit breaker switch with multiple phase protection according
the following table with contact aperture distance, equal to or not exceeding
3mm and a supply cable no less than 2.5mm².

For other supplies the cable cross section and the circuit breaker switch must
be calculated according to voltage and length of cabling. If cabling too long
adjust cable size to Amp rating; do not pull on supply cable or install it under
tension. If cable needs to be replaced use type H07RN-F.
