Initial Start Up:
1. Remove the front, top and side panels.
2. Locate and open the receiver “king” valve.
3. Locate the AutoIQ Controller.
4. Switch on the electrical power. Note that the
LED or indicator lights all flashed on briefly.
5. Open the water supply valve.
6. 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 inlet water valve will open to fill the
reservoir. The inlet water valve will shut off
when the reservoir is full.
• The water pump starts to pump water.
•
The water solenoid opens again to refill the
reservoir.
• After 30 seconds the liquid line valve is
energized, allowing the compressor &
remote fan motor to start.
• 5 seconds later the hot gas valve closes.
Freeze Cycle:
•
The Freeze indicator light will come on. The
machine will stay in a Freeze cycle for many
minutes. Slush may appear in the reservoir,
it is temporary and normal.
•
Under certain conditions, the pump may stop
for a few seconds and then the inlet water
valve may open to refill the reservoir.
•
The freeze cycle will continue until the water
level in the reservoir drops to its factory set
point, then the Harvest Cycle will begin.
Harvest Cycle:
•
The Harvest indicator light will be ON,
• The hot gas valve will open.
• The water pump will switch off. The pump
will restart part way thru the harvest cycle.
• The Inlet water valve will open. The machine
will fill the reservoir and overflow it for a
specified number of seconds then shut off.
The harvest cycle may still be in progress.
• The Bin Full indicator light will go on and off
as ice falls from the evaporators.
7. Machines are shipped from the factory with the
purge level set to accommodate average water
conditions. To achieve optimal machine
performance, set the purge level to the minimum
setting.
Note: While the amount of water purge is
adjustable, only those installations with a water
supply known to be excellent (very low TDS)
should adjust to the minimum setting. See page 16
for purge adjustment procedures.
8. The machine’s correct cube size should result
in ice that falls from the evaporator in vertical strips
of 8 - 10 cubes, the top two cubes may fall
individually.
9. After a few minutes the machine will return to a
freeze cycle.
10. Fill out the Customer Evaluation and Warranty
Registration. Send it to Scotsman.
11. Return all panels to their normal positions.
12. Inform the user of the location and telephone
number of the local service company. Also inform
the user of the required maintenance of the
machine.
Operational Notes:
1. The machine will only shut off on Bin Full at the
end of the Harvest Cycle after the bin fills. That
last harvest cycle will be for Maximum Harvest
Time.
2. After switching off on Bin Full, if ice is removed
from the bin, the machine will not restart until it has
been off for 5 minutes. If the Freeze button is
pushed, the machine will restart immediately.
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.
