DOOR SWITCH
When opening the door a special microswitch (see Fig. 8)
disconnects the power from the machine electrical system.
The trasformer inside the support cabinet remains ener-
gised.
The differential switch must be used to disconneted it.
With the door open, there is no access to energised
parts. Inside the machine, the only parts that stay
energised are those protected by covers and carrying
a plate with the warning “Disconnect the power before
removing the protective cover”.
Before removing such covers disconnect the machine
from the power grid.
To energize the system with the open door, simply insert
the special key into the slot (see Fig. 8).
All operations which require the machine to be ener-
gised with the door open must be carried out by
qualified personnel who are aware of the specific risks
of such condition.
WATER SOFTENER UNIT
The machine is sold without water softener.
Should the water be very hard, a water softener cartridge
can be installed, using the connections provided in the
hydraulic circuit.
The cartridge should be replaced according to the manu-
facturer’s instructions.
INSERTING THE PRODUCT LABELS
The menu and instruction labels are supplied with the
machine and must be inserted at the time of installation
according to the layout and to the language (see “selection
dose” table).
LENGTH OF STIRRERS
The correct installation position of the stirrer stacker (see
Fig. 8) must be checked according to the length of the
stirrers to be used (105 mm by default).
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).
When the machine is completely empty the “No Water”
failure is indicated.
When the programming button located on the internal side
of the push-button board (see Fig. 19) is pressed twice the
machine will be set to “Programming” mode; when press-
ing the selection buttons 3 and 6 in a sequence, the
machine will go through an installation cycle, and namely:
- the water supply pump is started to fill the air-break;
- the milk solenoid valve is opened so that the air may
be bled from the boiler and 400 cc. of water filled.
- the message “Installation” will be shown on the display
for the entire duration of the cycle;
N.B.: If there is no water flow from the mains during the
installation cycle, the machine will stop until water is
resumed or the machine is switched off.
IMPORTANT NOTICE!!!
If a considerable amount of air bubbles is formed in the
water system, for example during maintenance, it is pos-
sible that an installation cycle need to be started when the
machine is switched on.
