System Controller
Indicator Lights:
Bin Full: On when bin is full, goes on and off as ice falls
during a harvest cycle.
Freeze: On when the unit is in the Freeze cycle, blinks
when a freeze mode is pending.
Harvest: On when the unit is in the Harvest cycle.
Clean: On when the unit is in the Clean cycle, blinks
when preparing for a clean mode.
Off: On when the unit has been switched off, blinks
when the machine is preparing to shut off.
Water: On when the controller has identified a problem
with the water system.
Refrigeration: On when the controller has identified a
problem with the refrigeration system.
Cycle Definitions:
Freeze: The refrigeration system is operating to remove
heat from the evaporators. The compressor, fan motor (if
air cooled) and water pump are ON.
Harvest: The refrigeration and water systems are
operating to harvest the ice cubes. While the compressor
is on for the full cycle, the water pump will be off at the
beginning and inlet water valve will switch off before
the end.
Clean: The Inlet Water Valve opens to fill the reservoir.
The Water Pump starts. The Clean indicator light is
switched ON. A manually initiated rinse flushes the
system.
Initial Start Up
1. Remove the front panel.
2. Locate and open the liquid line valve.
3. Double check quick-connect couplings for leaks.
4. Locate the Controller.
5. Check for electrical power. The Off light on the controller
should be glowing.
6. Open the water supply valve.
7. Push and release the Freeze cycle push button (the Freeze
indicator light will blink until the compressor starts). The next
several operations are automatic.
Initial Start (30 seconds)
The Freeze light will begin to blink.
The hot gas solenoid valve will be open.
The purge valve will be open
The water pump will be on
After 30 seconds, the hot gas valve closes
The purge valve will shut and the inlet water valve will open to
fill the reservoir. The inlet water valve will shut off when the
reservoir is full.
The compressor & remote fan motor start.
Freeze Cycle
The Freeze indicator light will come on. The unit will be in a
Freeze cycle for many minutes. Slush may appear in the
reservoir, it is temporary and normal.
The pump will stop for a few seconds a few minutes into the
freeze cycle
The freeze cycle will continue until the water level in the
reservoir drops to its factory set point, the first time that
happens the water valve will re-fill the reservoir. The second
time it happens in a freeze cycle starts the Harvest Cycle.
Harvest Cycle:
The Harvest indicator light will be ON,
The hot gas valve will open.
The purge valve will be open for 74 seconds.
The water pump will switch off. The pump will restart part way
thru the harvest cycle.
The purge valve closes.
The Inlet water valve will open for a short time
