7) Check an ice production cycle ensuring that the cube
plate is conveyed into the storage bin and that all
operations are performed regulary.
8) Verify the working of the machine-stopping
microswitch by keeping the splash-guard deflector
oper for over 30 seconds.

FUNCTIONING:
The ice cubes are produced within a special hive-like
vertical copper evaporator.
A circulation pump produces a continuous water flow on
the gront 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
sesnor. Such a sensor is made us 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 finally touches them, thus
closing the electronic circuits whitch causes at the same
time:
- The sending of warm gas to the evaporator, by
opening a solenoid valve, anc the consiquent
disjunction of the 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 elecrronic card, which, in turn
restores the normal ice-production cycle.
When the container is full, the last ice-cube plate keeps
the baffle open and, therefore, the microswitch contacts
do not close.
Thus, the electronic card, connected to the microswitch,
stops the machine within 30 seconds.
The removal of the ice from the collecting bos allows the
baffle to restore its normal position, and therefore the
producer is started again.
A complete cycle takes from 15 to 30 minutes,
depending on water and room temperature.

CLEANING AND MAINTENANCE
NOTE:
Observe safety practice: disconnect the machine from
electricity supply before cleaning and mainance
operations.
Q
CLEANING OF THE AIR CONDENSER
The gradual accomulation 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 in the
back of the machine and to clean in either withanon-metallic
brush, or better with a vacuum cleaner (pict. nr. 23).

CLEANING OF WATER INFLET FILTER
Close the shut-off valve of the water supply, take out the
water inlet probe filter and rinse the filtering part under a
water flush and reassemble.
CLEANING OF THE CABINET ESTERIOR
Clean using a clean cloth and warm water.
CLEANING OF THE AIR STORAGE BIN
Remove the ice from the storage bin. Clean the interior
with a sponge wetted in warm water with a little sodium
bicarbonate: rinse with clean water and dry throughtly.

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 hydraulich system.
The washing operation should be carried out by a service
technician.
The washing frequency depends upon the hardness of
the water. It is advised that the washing opeation is
carried our at least twice a year.
