theelectrical components duringthe Testing
Mode. Used to by-pass the 3' stand by time
(just jumpthecontactswith PCBoard under
power).
J2 - SYEN / J3 - Pro. El. Ind. - 60/70°C:
Used to set up the CutOut temperature
of the condenser sensor:
• Jump OUT = 60°C
• Jump IN = 70°C
J3 - SYEN / J2 - Pro. El. Ind. - · 3'/60':
Used to set up the start up delai time:
• Jump IN = 3'
• Jump OUT = 60'
H 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 for-
mation and fluidity.
On the inner side of the reservoir cover are fit-
ted the twowater level sensor pinswhich detec-
ts the presenceor theshortageof water inthe-
reservoir.
I Freezing cylinder or evaporator
The freezing cylinder ismade of a stainless steel
vertical tube onwhich exterior iswrapped aro-
und the cooling coil with the evaporating cham-
ber 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
bottompart, freezes into ice when in contact
with the cylinder inner walls. The ice is then lif-
ted up by the rotating auger and compacted
and forced out by the ice breaker.
J Eisbrecher
Der Eisbrecher befindet sich im oberen Teil des
Freezers und wirkt dem an den Zylinderwänden
aufsteigendem Eis entgegen, das auf diese
Weise komprimiert wird, so dass ein Teil des
darin enthaltenen Wassers beseitigt und das
Eis in viele Körnchen gebrochen wird, die in
den Behälter befördert werden.
Im Eisbrecher befindet sich das obere Lager,
das aus zwei Reihen Rollen aus rostfreiem Stahl
besteht, die den von der Schnecke ausgeübten
radialen und axialen Belastungen standhalten
können.
Dieses Lager ist mit einem speziellen, wasser-
abstoßenden Lebensmittelschmierfett
geschmiert.
NOTE.
It is very important tomake sure of the
correct fitting of the cover on the reservoir in
order to enablethesensor to efficiently control
the water situation avoiding undue shutoff inter-
ventions.
ANMERKUNG.
Es wird empfohlen, alle sechs
Monate den Zustand des Schmiermittels und
des oberen Lagers zu überprüfen.
