WATER CIRCUIT
The water enter in the machine through the
water inlet fitting which incorporates a strainer -
located at the rear side of the cabinet - then it
goes to the water reservoir flowing through a
float valve.
The float reservoir is positioned at the side of the
freezing at such an height to be able to maintain
a constant water level. The water flows from the
reservoir into the bottom inlet of the freezer to
sorround the stainless steel auger which is verti-
cally fitted in the center of the freezer.
In the freezer the incomingwater gets chilled into
soft (slush) ice which is moved upward by the
rotating action of the auger. The auger rotates
counter-clockwisewithin the freezer powered by
a direct drive gear motor and carries the ice
upward along the refrigerated freezer innerwalls
andbydoingso theice gets progressively thicker
and harder.
The ice, being costantly lifted up, meet the teeth
of the ice breakerwhich is fitted on the top end of
the auger,where it gets compacted, cracked and
forced to change from vertical into horizontal
motion to be discharged out, through the ice
spout and chute, into the storage bin.
NOTE.
The presence of thewater in the float
reservoir is detected by a system of two sen-
sors which operates in conjunction with the P.C.
Board. The two sensors use the water as a con-
ductor to maintain a low voltage current flow
between them. In case the water used is very
soft (de-mineralized) or the float reservoir gets
empty the current flow between the sensors
become so weak or is no longer maintained
that, as consequence, the P.C. Board shutoff
the flaker operation with the simultaneous
glowing of the
YELLOW LED
signalling
“Shortage of water”.
