How the machine uses the water
The ice maker begins with a fixed charge of water that is contained in the water trough. As
the water flows to the freezing evaporator surface, the portion of water that does not
contain mineral impurities freezes and sticks to the ice cube molds. The water containing
impurities falls back into the water trough. During the ice making process, fresh water
enters into the water trough continuously as the water in the trough freezes continuously in
the evaporator.
How the drain system operates when water is pumped out
The components of the Pump-Out Water Drain System are
• Water reservoir
• PC Board & Water level switch 1, 2
• Water Drain Pump
OPERATION
• All water coming from the overflow and the melted ice is
collected in the water reservoir.
• As soon as the water in the reservoir reaches the maximum
level, the water level switch 1 closes, transmitting a low
voltage current to the PC Board.
