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 a plate near the rear side of the appliance.
The manufacturer declines any responsibility for any damages caused by lack
of an effective ground installation.
The machine shall be connected to a 16A wall circuit breaker switch with
contact distance, equal to or not exceeding 3mm and a supply cable no less
than 2.5mm². The cable cross section must be calculated according to voltage
and length of cabling. If cabling is too long adjust cable size to Amp rating;
do not pull supply cable or install cable under tension. If cable needs to be
replaced use type H07RN-F.
2)WATER CONNECTION
Install a 55°C water tap in a well accessible place, terminating in a 3/4"
fitting, which the pipe strainer and inlet hose shall be connected to.
Carefully comply with any national or regional regulations in force.
The operating pressure should be neither less than 2 bars or greater that 4
bars (200/400 kPa). If water pressure is inferior then 2 bar, a pressure
increase pump is necessary. If water pressure exceeds 4 bar, a pressure
reducer is necessary.
In order to obtain best results, it is suggested that the water supply have a
hardness not greater that 8 Clarke.
