INSTALLING THE PAYMENT SYSTEM
The machine is sold without payment system, there-
fore the installer of such a system is responsible for
any damage to the machine or to things and persons
caused by faulty installation.
- Fit the coin mechanism and make sure that all relevant
parameters are programmed correctly;
- adjust the selector opening cam bracket in such a way as
to allow the selector to open completely;
- adjust the coin chute according to the type of coin
mechanism.
WATER SOFTENER UNIT
The machine is sold without water softener.
Should the water be very hard, a water softener cartridge
or an ion-exchange resin water softener unit can be
installed in the cabinet.
The water softeners, available as accessory, must be
replaced or regenerated regularly following the directions
of the manufacturer.
FILLING THE WATER SYSTEM
When the machine is switched on the condition of air-
break (full or empty), pump (electrical functioning and
water flow) and boiler (pressure) are checked.
If required by the conditions, the machine will automati-
cally start an installation cycle, and namely:
- the display will show "Installation" for the entire duration
of the cycle;
- the water mains solenoid valve is opened or the water
supply pump is started to fill the air-break;
- (for espresso models only) instant product solenoid valve
is opened so that air may be bled from the boiler and 400
cc. of water filled.
N.B.: If there is no water flow during the installation cycle,
the machine will lock until the water is resumed or the
machine is switched off.
Versions with internal tank
IMPORTANT NOTICE!!!
For models with an internal tank, when the machine is
first switched on, the installation procedure MUST BE
carried out manually (see relevant chapter).
CONNECTING THE MACHINE TO
THE POWER SUPPLY
The machine is designed to operate under a single-phase
230 V~ voltage and is protected by 10 A fuses.
Before making the connection make sure that the ratings
correspond to those of the power grid, and more specifi-
cally:
- the supply voltage rating should be within the limits
recommended for the connection points;
- the main switch should be capable of withstanding the
peak load required, and at the same time ensure proper
omnipolar disconnection from the power grid with an
opening gap of the contacts of at least 3 mm.
The main switch, the power outlet and the plug should
be located within easy reach.
The power cable is of the type fitted with a fixed plug.
Any replacement (see Fig. 11) should be done by qualified
personnel only, using exclusively cables of the type HO5
RN - F or HO5 V V-F or H07 RN-F with a section of 3x1-
1,5 mm
2
.
The electrical safety of the machine is ensured only when
it is correctly and efficiently earthed according to the safety
standards in force.
This fundamental safety requirement must be duly
verified, and if in doubt the system must be carefully
tested by qualified technicians.
Do not use adapters, multiple sockets and/or exten-
sions.
Before switching the machine on, be sure it is correctly
connected to the water mains and the cutoff valve is open.
THE MANUFACTURER DECLINES ALL RESPONSI-
BILITY FOR ANY DAMAGE CAUSED BY NONCOMPLI-
ANCE WITH THE ABOVE MENTIONED SAFETY RULES.
DOOR SWITCH
When opening the door a special microswitch disconnects
the power from the machine electrical system.
With the door open, no energised parts can be ac-
cessed. Inside the machine the only energised parts
are the ones which are covered with protective cas-
ings which are marked with a plate indicating “before
removing the cover disconnect the power”.
Before removing these covers it is necessary to dis-
connect the machine from the mains.
To energize the system with the open door, simply insert
the special key into the slot (see Fig. 1).
All operations requiring the machine to be energized
with the door open should be carried out with the door
switch key inserted, and therefore by qualified per-
sonnel informed about the specific risks of such
situation.
