Initial Start Up
1. Remove the front and left side panels.
2. Locate and open the liquid line valve.
3. Double check quick-connect couplings for leaks.
4. Locate the AutoIQ 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 shuts 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
•
The Bin Full indicator light will go on and off
as ice falls from the evaporators.
8. 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 the next
page for purge adjustment procedures.
9. After about
6 minutes
(first cycle after any
restart) the machine will return to a freeze cycle.
Note: After the first harvest, the controller adjusts
the harvest time as needed to release all ice.
10. The reservoir refills at the beginning of Freeze.
11. Fill out the Customer Evaluation and Warranty
Registration. Send it to Scotsman.
12. Return all panels to their normal positions.
13. Inform the user of the location and telephone
number of the local service company. 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 about 6 minutes long.
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 4 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.
4. When shutting off, the compressor will run for 30
seconds (everything else will be off) and then
switch off.
