E. Check to see through the ice discharge opening that the spray system is correctly seated and that the
water jets uniformly reach the interior of the inverted mold cups. Also, make sure that the plastic
curtain is hanging freely and there is not excessive water spilling through it.
F. The ice making process begins with the water sprayed into the molds that gets gradually refrigerated
by the heat exchange with the refrigerant flowing into the evaporator serpentine. During the freeze
cycle, the evaporator temperature falls to 32˚F (0˚C) (red LED blinking as per Fig. 4) and then to 5˚F (-
15˚C) (red LED ON steady as per Fig. 4a). When it reaches 5˚F (-15˚C), the evaporator temperature
sensor supplies a low voltage power signal to the electronic control device (PC Board) in order to
activate an electronic timer. This takes over the control of the freeze cycle up to the complete
formation of the ice cubes.
