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.

K.

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.

L.

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).

H.

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.

J.

FREEZING CYLINDER or EVAPORATOR

(Two on SFN1000 Model)

The freezing cylinder is made of a stainless steel

vertical tube on which exterior is wrapped around
