Initial Start Up - Scotsman CME1356 User Manual

CME1356 and CME1656

Initial Start Up

1. Remove the front panel.
2. Locate the AutoIQ Controller.
3. Switch on the electrical power. The controller's
indicator lights all flashed on briefly. Blue
controllers also begin to flash their red lights and
the Freeze light will be on. After 20 seconds the
red lights stop flashing, the Freeze light goes out,
the Bin Full and Off lights switch on and then the
Bin Full light goes out. The Off light will be glowing.
4. Open the water supply valve.
5. Push and release the Freeze switch (the Freeze
indicator light blinks until the compressor starts).
Initial Start
·
The Freeze light will begin to blink.
·
The Hot Gas Solenoid valve will be open.
·
The Purge valve will be open.
·
The Water pump is on.
·
The hot gas and purge valves close and the
inlet water valve opens to fill the reservoir and
shuts 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.
·
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. 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 18
for purge adjustment instructions.
7. 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.
8. After about 6 minutes the machine will return to
a freeze cycle.
Note: After the first harvest, the controller will
adjust harvest time as needed to release all ice.
9. The water valve will re-fill the reservoir at the
beginning of freeze.
10. Collect and discard the first batch of ice. Rinse
out the bin.
11. Fill out the Customer Evaluation and Warranty
Registration. Send it to Scotsman.
12. Replace the left front panel.
13. 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.
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. This 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
