Component Location And Function - Scotsman CME256 Product Manual

Component Location and Function:

Reservoir: Contains the water charge used for
every batch of ice.
Water Inlet Valve: Opens to allow water into the
reservoir.
Water Level Sensor: Controls the size of the ice
cube by measuring how much water is used in a
cycle. It consists of a float, stem and electric eye.
The stem will move slightly when the pump is on,
this is normal. As the machine makes ice the
reservoir water level will fall and the visible portion
of the stem will slide down thru the slot in the
sensor body.
AutoIQ Controller: Controls the complete
operation of the ice machine. Turns it on and off;
switches it between cycles; shows information via
indicator lights; and shuts the machine down if
there is a problem.
Evaporators/Freezing Compartment: Location of
the evaporators. Ice forms on the evaporators and
is released when warmed up during the harvest
cycle. The freezing compartment is fully insulated
for maximum efficiency.

Cube Deflector: The slots in the inclined deflector
let the water falling from the evaporators back into
the reservoir, but when ice falls during harvest, the
ice slides off into the bin.
Refrigeration Service Access Valves: Only to be
used by a certified technician. Allows access to the
refrigeration system for diagnostic information.
Water Pump: Forces the water from the reservoir
to the top of the evaporator(s). The motor is
separated from the reservoir water to minimize
contact with the water.
Compressor: The refrigerant vapor pump, it
forces the refrigerant to flow thru the refrigeration
system tubing.
Hot Gas Valve: Closed during freeze, it opens
during harvest to divert hot discharge refrigerant
gas into the inlet of the evaporators.
Condenser: Either air or water cooled, discharges
the heat produced in ice making.
