Scotsman ice machines have always been the smart choice for ice,
combining reliability with the industry's best energy consumption
and groundbreaking innovations including automatic variable purge water.
Scotsman leads the industry with the latest smart technology
found in the new Prodigy modular cube ice machine.
To show the line's ease of operation and servicing, let's take a walk through.
Beginning with the smart technology of the auto alert indicator light panel
on the upper left corner of the front panel.
It contains easy to reach on and off switches plus the power indicator light.
The green status light shows the machine is operating correctly in the ice making
mode. If the mission malfunctions, the light blinks red.
The water light signals a water supply problem by blinking red if the reservoir fails to fill properly.
This smart machine makes maintenance a breeze.
The descale and sanitation light is normally off
changing to yellow when it's time to descale and sanitize.
The cleaning process described later turns the light off.
The panels are easily removed using the Phillips head screwdriver.
First, the two screws at the top of the front panel,
then two screws at the front of the top panel, freed by lifting and pushing it back an inch.
Side panels are easily removed from the front
and the unique sound shield under the front panel is also easily removed.
The internal components are now open to clear view and easy access.
The controller,
the water level sensor,
the ice thickness sensor,
the curtain switch,
the water inlet valve,
water purge valve,
hot gas valve,
and evaporator.
All easy to reach without moving the machine.
Ice is produced two cycles:
First, the freeze cycle.
When it begins, the controller drains the reservoir, refilling it when the mid
length probe is uncovered - stopping when the water touches the top probe.
Freeze cycles, which followed the harvest cycles, refill but do not drain the
reservoir.
The compressor and water pump start and the fan begins blowing hot air out the
back of the machine.
When the water reaches a preset temperature the pump shuts down for
thirty seconds.
Then restarts and ice begins forming on the evaporator.
When the water touches the ice thickness sensor for a few seconds, the ready
to harvest light links - becoming steady as the harvest cycle begins.
Harvesting begins as hot gas heats the evaporator and the harvest assist
solenoid pushes the ice slab from the evaporator.
The cubes being held together by thin ice bridges.
The harvested ice forces the curtain open, actuating the curtains switch - which tells
the controller the ice has been harvested, ending the cycle.
The hot gas and harvest assist are shut off and the curtain closes
ready for the next freeze cycle.
During harvest a water purge has been taking place.
The freeze cycle does not use all the water that flows over the evaporator to make ice.
some of it is drained out every cycle to reduce hard water scale.
To reduce scale build-up, Prodigy machines with water sends technology
automatically vary the amount of water purged based on water purity.
