NOTE. If, after tenminutes fromthe unit start
up, no ice is made and the evaporating
temperature detected by the evaporator
sensor results to be higher than -1°C (30°F)
the ice maker stops (compressor first and
gear motor 3' later) and the 5th WARNING
YELLOW LED blinks.
The machine will remain in OFF mode for
one hour then it will restart automatically.
In case the unit trips OFF again in alarm for
3 times in 3 hours, themachine SHUTSOFF
DEFINITIVELY.
MECHANICAL SYSTEM
The mechanical system of the Flaker machines
consists basically of a gear motor assembly
which drives, through a ratched coupling, a
worn shaft or auger placed on its vertical axis
within the freezing cylinder.
The gear motor is made of a single phase elec-
tric motor with a permanent capacitor. This
motor is directly fitted in the gear case through
which it drives - in counter clockwise rotation at
a speed of 9.5 r.p.m. - the freezer auger being
linked to it by the ratched coupling.

Too low ambient and water temperature (well
below the limitations of respectively 10°C and
5°C - 50°F and 40°F) or frequent interruptions
of the water supply to the freezing cylinder
(clogging of thewater hose connecting the
float reservoir to the water inlet at the bottom
of the freezer) may cause the ice to get too
hard and compact loosing fluidity and the-
reby seizing the auger.
This situation will put under excessive strain
and load the entire drive system and freezer
bearings.
ANMERKUNG. Zur Wiederherstellung des
Betriebs nach Behebung der Ursache für die
Abschaltung müssen die oben angegebenen
Schritte, wie bei Drehung in die falsche
Richtung, durchgeführt werden.
