WATER SYSTEM
A combination of a solenoid water inlet valve with
a water level sensor is used to control the level of
the water into the reservoir/sump.
A pump, running continuously, after the first 30"
of freezing cycle, forces the water to the top of the
evaporator, where it is distributed through a

water tube and then cascades down the
evaporator surface by gravity. As it flows accross
the refrigerated evaporator, some of the water
will be chilled enough to change form, turn to ice,
and stay frozen onto the evaporator cells. Most of
the water returns to the reservoir, to be sucked
back into the pump, and repumped over the
evaporator.
