Two seal rings, one fitted on the rotor shaft and
the other on the output shaft keep the gear case
sealed.
Hovewer, the interior can be inspected and
serviced by unbolting the two halves of the
aluminium gear case housing.
The gear reducer output is connected to the
freezer auger that engages themselves only if
turned in the correct direction namely,
conterclockwise.
M. FAN MOTOR (Air cooled version)
The fan motor is controlled through the P.C.
BOARD and the TRIAC by the condenser tem-
perature sensor. Normally it operates to draw
cooling air through the condenser fins.
In cold ambient situation, the fan motor can run
at intermittance as the condenser pressure must
be kept between two corresponding head
pressure values.
N.
COMPRESSOR
The hermetic compressor is the heart of the
refrigerant system and it is used to circulate and
retrieve the refrigerant throughout the entire
system. It compresses the low pressure
refrigerant vapor causing its temperature to rise
and become high pressure hot vapor which is
then released through the discharge valve.
O.
ICE DISPENSER DRIVE MOTOR
Located on the lower side of the storage bin, it
turn by a milled shaft the dispensing vane placed
inside the round storage bin.
By rotating, the dispensing vane pushes the ice
towards the bottom rectangular opening so to
force the nugget ice to go through the bottom
outlet spout.
P.
STORAGE BIN
Round shaped it is located in the front of the ice
machine and has the main reason to store the ice
produced by the evaporator till it reaches its
maximum level controlled by an infrared optical
system. In its bottom is placed the ice spout as
well as the water drain hole.
Inside the ice spout opening is also located the
water outlet tube connected to the solenoid val-
ve.
Q. DISPENSING WATER SOLENOID VALVE
Normally closed and located in the upper left side
behind the front panel, it is energized and
controlled by the P.C. Board, it allows a metered
quantity of not chilled water to be dispensed
through its spout.
R.
WATER INLET SOLENOID VALVE
Normally open and located in the lower side of
the rear panel, it is energized and controlled by
the P.C. Board, it allows the entrance of the water
in water circuit of the machine for the ice
production.
S.
WATER DRAIN SOLENOID VALVE
Normally closed and located in the lower side of
the rear panel, it is energized and controlled by
the P.C. Board during the purge procedure during
every start-up of the machine when it is switched
ON and every twelve hours of operation. It drain
all the water from the reservoir and freezer to
prevent the growth of bacteria and algae when
machine is not working for many hours (Night-
time and/or Bin full condition).
T.
SAFETY P.C. BOARD
Located on the rear side of the machine, it is
connected with safety switch and ON/OFF green
push button to let them work with low voltage for
safety reason.
