Important notice!!
Access to the machine interior for maintenance and/or
repairs is via the back panel.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel.
Installation on the cabinet
The machine must be placed on the special support
cabinet, which houses: the liquid waste tray, the water
supply kit, the payment system and, in the case of very
hard water, the softener unit.
WARNING FOR INSTALLATION
The machine installation and the following mainte-
nance operations should be carried out by qualified
personnel only, who are trained in the correct use of
the machine according to the standards in force.
The machine is sold without payment system, therefore
the installer of such system has sole responsibility for any
damage to the machine or to things and persons caused by
faulty installation.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel. Height 650 mm

LOADING AND CLEANING outside of the door (see Fig. 1).
DOOR SWITCH
When opening the door a special switch disconnects the
power from the machine electrical system to allow the
operations described below, regarding filling and routine
cleaning.
All operations requiring the machine to be energized
should be carried out by qualified personnel ONLY,
informed about the specific risks of such situation.
MAINTENANCE AND DISINFECTION
According to current safety and health rules and regula-
tions, the operator of an automatic vending machine is
responsible for the hygiene and the maintenance of the
foodstuff circuits, to prevent formation of bacteria.
At installation the hydraulic circuits and the parts in
contact with foodstuff should be fully sanitised to
remove any bacteria which might have formed during
storage.
It is advisable that specific sanitising agents (such as Fig. 1
chlorine-based detergents or similar) are used for cleaning

COFFEE UNIT OPERATION When the doser unit is full, the ground coffee dose is

14). At the end of the dispensing cycle and during a pause of 3
seconds, the pre-brewing spring (5) will discharge the
water through the third way of the dispensing solenoid
valve, lightly pressing the used coffee dose.
By completing its rotation, the ratiomotor makes the swing-
ing lever (6) lift the pistons and the coffee dose.
At the same time, when the brewing chamber returns to its
vertical position, the scraper on the coffee hopper stops the
used coffee dose and drops it.
The lower piston now returns to the bottom dead centre.
