Harvest Cycle
The ice slab, when released, slides off of the evaporator plate onto the cutting grid, where it begins to be divided into
individual cubes that fall into the bin.
(See Figure 3-7 and Figure 3-8)
In the 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 to the drain.

Clean Cycle
In the water system, the water pump circulates the cleaning solution that has been added to the reservoir up to the
distributor, across the evaporator, and back into the reservoir where it is recirculated while the service control switch
is in the “CLEAN” position.
