MAIN SWITCH
The power supply unit (see Fig. 23) is fitted with a
microswitch that, when opening the sliding compartment,
disconnects the power from the machine electrical sys-
tem,
except from the terminal board supporting the line
cable, the line fuses and from the same switch area.
Before removing the cover from these parts (indicated
with a specific plate) it is necessary to disconnect the
external switch.
The power supply can be reconnected, if necessary, by
inserting the special key supplied with the machine.
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.
DISPENSING COMPARTMENT
MANUAL RELEASE
Some models are fitted with a lock device in the dispens-
ing compartment that is released through electric control
when a selection is made (see compartment lock param-
eters).
Should for any reason be necessary to open the compart-
ment without electric power, do as follows:
- remove the last tray;
- remove the anti-theft grille;
- manually operate the lock device (see Fig. 27).
The cooling unit is located in the lower part of the cabinet.
When sliding sideway all the shutters on the cold air
distribution duct, lining up the duct holes with the ones on
the shutters (shutters in the open position), a uniform
temperature is obtained in the cabinet (setting between
5°C and 20°C).
With the ventilation grille partially covered by the shutters
in the closed position, the temperature in the cabinet is
diversified between the upper trays, with the correspond-
ing holes on the duct closed by the shutters (12-18°C), and
the lower trays, with the holes on the duct open (5 -8°C).
According to the number of shutters in the open or closed
position, it changes the level of temperature stratification
in the cabinet.
The cooling unit is defrosted automatically every 6 hours.
In any case, the timing is programmable.
The power supply unit, mounted in the lower section of the
cabinet, contains the relay card which activates the com-
pressor, the protection fuses and the switch on the pay-
ment system door.
