How The Ice Maker Makes Ice
Set the ON/OFF button to the ON position. The ice maker will automatically go to the ice making stage.
There are two distinct cycles: ice freeze and harvest.
1. The freeze cycle happens when water flows to the evaporator surface.
2. The harvest cycle is when the ice is released and water enters the ice maker.
20 Minutes: A complete cycle takes about 20 minutes, but it depends on temperature and operating conditions.
Freeze: During the freeze cycle the compressor is pumping refrigerant, the fan motor is blowing air, and the water pump
is circulating water. When the batch of ice has been fully formed, the ice maker stops the freeze cycle and harvest cycle
begins.
Harvest: During the harvest cycle the compressor is still operating, but the water pump has stopped. The hot gas valve
opens, diverting hot refrigerant gas into the evaporator. The hot refrigerant gas warms the evaporator, causing the cubes
to slide as a unit off the evaporator and into the storage bin. The freeze cycle will restart when all the cubes have been
harvested.
How The Ice Maker 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 trough freezes continuously in the evaporator
.
MIM50P and MIM50P-O DRAIN SYSTEM OPERATION
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
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.
