HARVEST CYCLE

Electrical System

When the set temperature of the evaporator thermistor is reached, it signals the electronic control to terminate power to the condenser fan, and the water recirculating pump. Power is then supplied to the hot gas valve and water fill valve solenoids.

If the evaporator thermistor is unplugged, the control defaults to the maximum freeze and harvest times.

Refrigeration System

The hot gas valve opens, allowing high pres- sure refrigerant gas to bypass the condenser, and flow through the condenser accumulating tube. The hot gas pushes the liquid refrigerant that has accumulated in the accumulator tube up into the evaporator. The hot liquid refriger- ant evenly heats the evaporator plate so that the ice slab releases quickly and evenly.

The ice slab, when released, slides off of the evaporator plate onto the cutter grid.

Water System

The water valve opens, allowing water to flow into the water reservoir pan. As the reservoir fills, the mineral-laden water from the previous Ice Making cycle, is flushed out the overflow tube.

As a result of the hot gas flow and the ice sliding off the evaporator plate, the evaporator tem- perature begins to rise. When the evaporator thermistor reaches the set temperature (6.5°F), the unit switches to the Ice Making cycle. This cycling between Ice Making and Harvest, con- tinues until the ice bin is full.

The electronic control board controls the vari- ous components and systems in the ice maker for each of the Ice Making and Harvest cycles.

When the ice maker’s service control switch is in the “On” position, and the bin is not full of ice, the evaporator thermistor determines whether the unit will be in the Ice Making, or the Harvest cycle.

If the thermistor is unplugged from the control board, the unit will cycle using maximum freeze and harvest times.

DIAGNOSTICS / CLEAN CYCLE

Electrical System

Power is supplied to the electrical components through the service control switch.

The electronic control board controls the vari- ous components and systems during the Diag- nostics/Clean cycle. During the first 25 sec- onds of the cycle, each component will operate for 5 seconds.

For the order of the components cycled, see the flow chart on page 6-5.

Water System

When the service control switch is in the ‘’Clean” position, the water recirculating pump circu- lates the cleaning solution that has been added to the reservoir, up to the water distributor, across the evaporator, and back into the reser- voir, where it is recirculated.
