Scotsman TDE470 - Manual (Page 10)

Component Location & Function
Evaporator. This is a vertical cylinder full of water
and refrigerated. Also in the cylinder is a slowly
rotating auger. The auger forces the ice up the
evaporator walls and compresses it at the top. The
resulting flaked ice then falls by gravity into the ice
storage bin.
Water Reservoir. The water reservoir contains the
inlet float valve and the water level sensor. The
float valve controls the flow of water into the
reservoir, and the water level sensor will stop the
ice maker if the water supply fails.
Ice Storage Bin. The ice storage bin is an
insulated plastic container that is open at the top
and has a spout at the bottom. There is a rotating
ice vane inside the bin that causes the ice to be
swept over the spout and dispensed. The vane is
rotated by a gear motor at the top of the bin.
Bin Cover. The bin cover not only keeps dirt from
the ice storage bin, it also is the support for the
dispense gear reducer and the location of the
electric eye bin controls.
Condenser. The TDE470 uses
an air cooled condenser. It blows
air out, away from the fan motor.
The heat removed from the water
is exhausted from the condenser.
Compressor. The refrigeration
system compressor provides the
force to move the refrigerant
around the system.
Auger Drive. The auger drive is
a direct drive gear reducer.
