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 suitable.

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 and a section
suitable.
