The Water pump is on.
The hot gas and purge valves close and the inlet water valve
opens to fill the reservoir. The inlet water valve will shut off
when the reservoir is full.
The compressor starts.
Freeze Cycle:
The Freeze indicator light will be on. The machine will stay
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 fan motor (of air cooled models) will begin to turn and
soon warm air will be forced out the back of the cabinet.
The freeze cycle will continue until the water level in the
reservoir drops to its factory set point; the first time that
happens in the freeze cycle will cause the controller to open
the inlet water valve to refill the reservoir, the second time in
the freeze cycle that this set point is reached 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 stop. It will restart in less than 74
seconds.
The purge valve closes and the Inlet water valve will open
for a short time to add water.
The Bin Full indicator light will go on and off as ice falls
from the evaporators.
6. The machine's correct cube size should result in ice
falling from the evaporator in vertical strips of 8 - 10 cubes;
the top 2 cubes might fall individually.
7. After about 6 minutes the machine will return to a freeze
cycle.
Note: After the first harvest, the controller will adjust the
harvest time as needed to release all ice.
8. The water valve will re-fill the reservoir at the beginning
of freeze.
9. Collect and discard the first batch of ice. Rinse out the
bin.
10. Replace the front panel.
11. Give the owner/user the manual, instruct him/her in the
operation of the unit, and make sure they know who to call
for service.
Notes On Operation:
1. The bin control signals the ice machine to shut off
whenever the bin becomes full, but the machine will not stop
until it has finished the next harvest cycle. his last harvest
cycle will be longer than the rest.
2. After the bin has filled the unit will not be able to restart
for 4 minutes. However, if needed, the Freeze button may be
pushed to restart the unit.
For example: If ice is removed from the bin immediately
after the machine has filled up and shut off, the Bin Full
light will be ON and the machine will not restart for 4
minutes.
3. If the bin controls sense a bin full signal before any water
is used (float stem up), the machine will shut off on bin full.
Note on Splash Panel Positioning: It is critical that the lower
splash panel be properly positioned. If removed during
installation or start up, check that it has been properly
returned to its original position.
How To Operate The System Controller
The System Controller is a microprocessor based device that
receives input from several sources and switches various
components on and off.
Its manual control is through the use of the Push Button
Control Switches
1. Freeze Button. Pushing and releasing this button starts or
restarts the machine. The System Controller remembers
what cycle it was last in and returns to that cycle.
2. Harvest Button: Pushing and releasing this button will
cause the machine to go directly to a Harvest Cycle. Can be
done from Freeze or Off. The machine will switch Off at the
end of the Harvest cycle.
3. Clean Button: Pushing and releasing this button will cause
the machine to empty the reservoir, refill and leave only the
water pump on for circulation of ice machine cleaner. After
the ice machine cleaner has circulated for about 10 minutes a
second push of this button will switch on the rinsing system
to flush out the dissolved scale and ice machine cleaner.
4. Off Button: Pushing and releasing this button will switch
the machine OFF at the end of the next cycle. If the button is
pushed and HELD for more than 3 seconds, the unit will
switch off immediately.
