Theory of Operation
Model UC-15I (Undercounter Ice Machine)
Water System
The water system provides and recirculates the
water for ice production. It also provides a
means of drainage. After the ice is produced, the
water system flushes the impurities and minerals
that were in the water, down the drain. (See
Figure 3-3)

Electrical (Electronic Control)
System
Power for the refrigeration system
and the water system in the model
UC-15I is provided through the
electronic control system. The
electronic control system also regu-
lates the operational cycles of the
ice machine. Refer to the Wire
Diagram at right (See Figure 3-4).
NOTE: The models UC-15IP and
UC-15IPO have a drain pump that
is powered off of L1, so even when
the ice machine is switched OFF,
the pump can continue to pump
melted ice water to the drain.
