WATER CIRCUIT
Water enter into the machine by the inlet line, where there is a small arille filer
located in the back side and here reach the wáter tank going through a float
valve.
PRINCIPLE OF OPERATION
NOTE: The presence of water in the tank is detected by a system of two
sensors that work together with the electronic board. Both sensors use the
water as a conductive to maintain a electric flow of low voltage that it is send
to the electronic board showing the presence of water in the tank. The lack of
water or the presence of soft water with an electrical conductivity with less of
30mS (demineralize waters)means the interruption of electrical flow to the
electronic boards and consequently the stop of the unit and the switch on of
the YELLOW LIGHT of ” lack of water”.
Tank of wáter is located allied of the evaporator case to a high that allows
through the communicative pipes, maintain constantly a correct level of
wáter inside the evaporator case.
Water enters from the tank through the conexion pipe inside the
evaporator case, where it is unfreeze and it is transformed in ice; this is
constantly mantained in movement by a stainless steel shaft that turn
inside the evaporator case.
The shaft, sumerge in water inside the evaporator turn in antitimetable
direction by the action of a reductive motor, pushing up the sheet of ice
that is formed in the internal cooled walls of the evaportor.
The ice, when it is push up by the shaft becomes more thick and when it
reach the crush it is compacted and cut into pieces, going through the outlet
pipe and falling into the ice keeper.
When the unit start up, it start up the continuous process of ice making,
process that continue until the ice keeper is full until the level sensors located
in the pipe of outlet ice.
When the ice interrumps the infrared beam of light between both electronic
eyes ( one or both in the model MF 61), the unit stops, the YELLOW LIGHT
switch on that shows the situation of full cabin.
