solenoid valve is activated again for a
few seconds till the water reaches the
maximum water level to reduce any
possibility of slush ice formation).

l) Replace the panels previously removed .
The ice cubes are produced within a special
hive-like vertical copper evaporator.
A circulation pump produces a continuous
water flow on the front grid; gradually, a
portion of the water turns into ice on the
inner walls of the small cells and forms
cubes, the height of which is controlled by
a special adjustable sensor. Such a sensor is
made up of two metal reeds, which are fed
by a low-voltage circuit, (insulated between
themselves), and kept at a certain distance
(adjustable through a screw) from the
evaporator. As the ice is produced, the
water film flowing on the ice itself
approaches the two reeds and finally
touches them, thus closing the electronic
circuits which operates simultaneously:

evaporator, by opening a solenoid valve,
and the consequent disjunction of the
partially joined cube plate from the
evaporator.
- The opening of the water-discharge
valve in order to remove any possible
residual impurity.
Once it has been disjuncted, the cube plate
slides away from the evaporator and moves
the front baffle (which is hinged in its upper
portion) toward the outside and with simple
gravity, falls into the container,
The front baffle, while rotating back and
forth, opens and closes the contacts to an
elecrtronic card, which, in turn restores the
normal ice-production cycle.
When the bin is full, the last ice-cube plate
keeps the baffle open and stops the switch
contacts from closing. Thus the electronic
card, connected to the switch, stops the
machine within 30 seconds.
The removal of the ice from the collecting
bin allows the baffle to restore its normal
position, and therefore the process is
started again.
A complete cycle takes from 15 to 30 mins
depending on water and room temperature.
If the machine stops because of irregular
working, the LED No. 2 will illuminate.
Wait at least 3 hours from the alarm
beginning, before pressing reset.
If the machine continues to malfunction call
a service technician.

Cleaning of the Air Condenser
The gradual accumulation of dust in the
condenser causes a significant reduction
in the refrigerating action of the machine
and consequently in its ice production. It
is recommended to inspect frequently the
condenser at the back of the machine
and to clean in either with a non-
metallic brush, or better with a vacuum
cleaner (Fig.23).

Cleaning of the Water Inlet Filter
Close the shut-off valve of the water
supply. Unscrew the water connection to
the machine and take out the water inlet
filter. Rinse the filtering part under
running water, when clean reassemble.

Cleaning of the Water Circuit
Attention
The machine is equipped with a new
semi-automatic washing device that
enables the effective cleaning of the
entire water system.
The washing of the entire water system
should be carried out by a service
technician.
The washing frequency depends upon
the hardness of the water.
It is advised that the washing operation is
carried our at least twice a year.
