the cooling coil with the evaporating chamber
and in its interior is located the auger which
rotates on its vertical axis and it is maintained
aligned by the top and bottom bearings. A water
seal system is located in the bottom part of the
freezer while at the top end is fitted the ice
breaker.
The water constantly flowing into the cylinder
bottom part, freezes into ice when in contact with
the cylinder inner walls. The ice is then lifted up
by the rotating auger and compacted and forced
out by the ice breaker.

ICE BREAKER (Two on SFN1000 Model)
The ice breaker is fitted in the freezer upper part
it has, on F120-F200 Model, two breaker teeth to
break the ice and with its slanted shape from the
rear tooth to the front one it compacts and forces
the ice out in an horizontal way.
On the other models the ice breaker is made by
several rectangular openings where the ice is
forced to pass through.
By undergoing this, the ice looses its excess of
water content so it drops into the bin in hard dry
bits of ice.
In the ice breaker it is housed the top bearing
which is made of two rolls bearings positioned to
withstand the auger axial and radial loads. This
bearing is lubricated with a food grade - water
resistant grease.
NOTE
. It is advisable to check the conditions
of both the lubricant grease and the top
bearing every six months.

GEAR MOTOR
(Two on SFN1000 Model)
The gear motor is made of a single phase electric
motor with permanent capacitor directly fitted on
a gear box.
The drive motor rotor is kept aligned on its
vertical axis by two ball bearings permanently
lubricated. The gear case contains a train of
three spur gears with the first one in fiber to limit
the noise level. All the three gears are encased
in case roller bearings and are covered by
lubricant grease (MOBILPLEX IP 44).
Two seal rings, one fitted on the rotor shaft and
the other on the output shaft keep the gear case
sealed.
The interior can be inspected and serviced by
unbolting the two halves of the aluminium gear
case housing.
G. JUMPERS
The Flaker PC Board is equipped by three jumpers:
J1 · TEST: Used in the factory to energise all
the electrical components during the
Testing Mode.
Used to by-pass the 3' stand by time
(just jump the contacts with PC Board
under power).

INTERFACE P.C. BOARD
(Only on SFN1000 Model)
Used only on SFN1000 model, it allows to elaborate
the signal received from both the electromagnetic
sensors as well as from both the optical ice level
controls transmitting it to the P.C. Board for the
control of the unit operation.
The Interface P.C. Board is equipped by four
INLET sockets (two for the electromagnetic
sensors and two for the optical ice level controls)
and two OUTLET plugs to be connected to the
sockets of the main P.C. Board.
I.
FLOAT RESERVOIR
The float reservoir consist of a plastic water pan
on which is fitted a float valve with its setting
screw. The float valve modulate the incoming
water flow to maintain a constant water level in
the reservoir, level that corresponds to the one in
the freezing cylinder to ensure proper ice
formation and fluidity.
On the inner side of the reservoir cover are fitted
the two water level sensor pins which detects the
presence or the shortage of water in the reservoir.
NOTE.
It is very important to make sure of the
correct fitting of the cover on the reservoir in
order to enable the sensor to efficiently control
the water situation avoiding undue shutoff
interventions.
