How It Works ICEU060

Water System
Freezing Cycle
The refrigeration process creates cold temperatures within the evaporator coils and removes heat from the
water sprayed up into the inverted ice cube cups. When enough heat is removed, the water changes into
ice, and forms where it is the coldest: in the ice cube cups.
Minerals contained in the supply water will not freeze and are drained away. Mostly pure water will be
frozen into the ice cubes.
During the freezing cycle, the compressor, fan motor, and water pump are operating. Water is continuously
freezing or being sprayed and recirculated. When the evaporator temperature is lowered to the cold
temperature setting of the cube size control, it ends the freezing cycle and starts the harvest cycle.
Harvest Cycle
The hot gas valve opens and hot refrigerant gas is discharged into the evaporator. The inlet opens and a
fresh supply of water flows to the top of the evaporator and then drains into the reservoir.
The ice cubes have been released from the inverted cube cups in the evaporator by the warming effect of
the hot refrigerant gas condensing in the evaporator tubing, plus the incoming water flowing around the
inverted cups. The released ice cubes drop onto the spray platform and through the curtain assembly into
the ice storage bin.
The cube size control thermostat senses the
warmer temperatures of the harvest cycle, and
at a preset temperature, opens the circuit to
the hot gas and inlet water valves. Both valves
then close.
The harvest cycle is complete, and the
freezing cycle restarts.
The automatic ice making process continues
until the bin is full of ice, and the bin thermostat
senses a colder temperature.
The bin thermostat then opens the circuit to all
components and the automatic ice making
process stops.
