INSTALLING THE PAYMENT SYSTEM
The machine is sold without payment system, therefore
the installer of such a system is responsible for any
damage to the machine or to things and persons
caused by faulty installation.
- Install the desired coin mechanism according to the
appropriate instructions and make sure that the relevant
parameters are programmed correctly.
- adjust the selector opening lever bracket to allow complete
opening of the selector;
- adjust the coin chute according to the type of coin
mechanism installed.
CLEANING THE SOFTENER RESINS
(MOD-
ELS C ONLY)
Before filling the machine water system the resins con-
tained in the softener unit must be cleaned, operating as
follows:
- remove the hose connected to the air-break from the
softener unit fitting (see Fig.16);
- insert a new hose, provided with the machine, onto the now
free hose fitting and direct it towards a drain;
- switch the machine on;
- bleed air out of the softener unit by loosening the plug, wait
until it is full of water and tighten the plug, let a few litres
of water flow out until it is clear;
- re-insert the hose connected to the air-break.

FILLING THE WATER SYSTEM
If the air-break device indicates the no-water condition for
more than 10 seconds after the machine has been switched
on, an installation cycle will automatically be started, and
namely:
- the display will show
"INSTALLATION"
for the entire duration of the cycle;
- the air-break and the instant product boiler are filled;
- (for espresso models only) the coffee solenoid valve is
opened so that air may be bled from the boiler and 800 cc.
of water filled.
N.B.: If there is no water flow from the mains during the
installation cycle, the machine will be blocked until the
water is resumed or the machine is switched off.
This operation must be carried out by hand, using the
special function from the "test" menu in "Technician" mode,
if the kit (optional) for water supply from an internal tank
is fitted or after any maintenance requiring the boiler to be
emptied but not the air-break.
