Water  
The quality of the water supplied to the ice machine Cube ice machines use more water than what ends  
will have an impact on the time between cleanings up in the bin as ice. While most water is used  
and ultimately on the life of the product. There are during ice making, a portion is designed to be  
two ways water can contain impurities: in drained out every cycle to reduce the amount of  
suspension or in solution. Suspended solids can be hard water scale in the machine. That’s known as  
filtered out. In solution or dissolved solids cannot  
be filtered, they must be diluted or treated. Water  
filters are recommended to remove suspended  
solids. Some filters have treatment in them for  
suspended solids. Check with a water treatment  
service for a recommendation.  
water flush, and an effective flush can increase the  
time between needed water system cleaning.  
In addition, this product is designed to  
automatically vary the amount of water flushed  
based on the purity of the water supplied to it. The  
water flush rate can also be set manually.  
Adjustments of flush due to local water conditions  
are not covered by warranty.  
Scotsman filters:  
A triple head filter is recommended for the potable  
water. Either the Scotsman SSM3 taste and odor  
filter system, or the ADS-AP3 Aqua Patrol system.

Potential for Airborne Contamination  
Installing an ice machine near a source of yeast or  
similar material can result in the need for more  
frequent sanitation cleanings due to the tendency  
of these materials to contaminate the machine.  
Most water filters remove chlorine from the water  
supply to the machine which contributes to this  
situation. Testing has shown that using a filter that  
does not remove chlorine, such as the Scotsman  
Aqua Patrol, will greatly improve this situation,  
while the ice making process itself will remove the  
chlorine from the ice, resulting in no taste or odor  
impact. Additionally, devices intended to enhance  
ice machine sanitation, such as the Scotsman  
Aqua Bullet, can be placed in the machine to keep  
it cleaner between manual cleanings

Uncrate and Set Up  
Begin with unpacking the ice storage bin. Remove  
the carton, and using part of the carton as a  
cushion, tip the bin on its back to remove the skid  
and attach the legs or casters.  
Bin Recycling  
Many times an ice machine head will be replaced,  
while the existing ice storage bin will be reused.  
This is an acceptable practice, if some precautions  
are taken:  
Note: Turn the leg levelers in all the way and adjust  
after the ice machine is on top and in its selected  
location.  
The used bin must be in good condition.  
Broken doors, hinges, or warped walls are  
reason for considering a new bin.  
Return the bin to an upright position. Check the bin  
top gasket for gaps and tears, fill any in with food  
grade sealant prior to placing the ice machine on  
the bin.  
The used bin top edge gasket must be  
replaced. Water leaks could occur if the  
gasket tape is not replaced.  
The used bin should be the proper size for  
the ice machine head.  
Install the bin top adapter if one is required for the  
application.  
If the ice machine has not been unpacked, do so  
now. Remove the carton from the skid. Lift the ice  
machine off the skid directly onto the bin.  
Note: The machine is heavy! Use a mechanical  
hoist if necessary.  
Secure the ice machine to the bin with the  
hardware provided (two metal straps and 4 bolts).  
Level the bin and ice machine using the adjustment  
part of the legs.

Plumbing Requirements  
All models require connection to cold, potable  
water. A hand actuated valve within site of the  
machine is required. Air cooled models have a  
single 3/8” FPT inlet water connection, a 3/8” FPT  
to 3/8” male flare adapter is supplied with the  
machine and can be used if desired.  
Water Filters  
If connecting to water filtration, filter only the water  
to the reservoir, not to the condenser. Install new  
cartridges if the filters were used with a prior  
machine.  
A triple head filter is recommended. Either the  
Scotsman SSM3 taste and odor filter system, or  
the ADS-AP3 Aqua Patrol system.

Install new tubing when replacing a prior ice  
machine, as the tubing will have been sized for the  
old model and might not be correct for this one.  
Vent the reservoir drain. A vertical vent at the back  
of the drain, extended about 8 – 10” will allow the  
gravity drain to empty and also keep any surges  
during draining from discharging water.

Use and Operation  
Once started, the ice machine will automatically  
make ice until the bin or dispenser is full of ice.  
When ice level drops, the ice machine will resume  
making ice.  
Caution: Do not place anything on top of the ice  
machine, including the ice scoop. Debris and  
moisture from objects on top of the machine can  
work their way into the cabinet and cause serious  
damage. Damage caused by foreign material is not  
covered by warranty.  
There are four indicator lights at the front of the  
machine that provide information on the condition  
of the machine.

The SmartBoard’s features include:  
The cuber drops ice in large sections. That ice will  
break up into random parts as it falls into the bin,  
but some large sections may remain on top of the  
ice in the bin. When removing ice, tap the groups of  
ice with an ice scoop to separate them into smaller  
units. In a dispenser, this ice will break up into  
mostly individual cubes as the dispense

SEL  
The ice machine will make noise when it is in ice  
making mode. The compressor, fan motors if air  
cooled and water pump all produce some sound. It  
is also normal to hear some cracking just before  
the harvest cycle begins. In addition, during the  
harvest cycle the harvest assist solenoid will click  
twice as it pushes the ice out and returns to its  
normal position. The ice harvests as a unit or slab,  
which makes some noise when it impacts the bin or  
dispenser. These noises are all normal for this  
machine.

Cleaning, Sanitation and Maintenance  
This ice system requires three types of  
maintenance:  
Remove the build up of mineral scale from the ice machine’s water system and sensors.  
Sanitize the ice machine’s water system and the ice storage bin or dispenser.  
Clean or replace the air filter and clean the air cooled condenser (air cooled models only).  
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without  
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of  
their water systems with a specifically designed chemical. This chemical dissolves mineral build up that  
forms during the ice making process.  
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine  
is cleaned and sanitized.  
The ice machine’s water system should be cleaned and sanitized a minimum of twice per year.

If there is imbedded grease, use a commercial coil  
cleaner to wash out the grease. Dust can be blown  
out with compressed air from the back with a  
vacuum cleaner operating in the fan area. Be  
careful not to damage the condenser’s fins. Use a  
fin comb to straighten any bent fins.  
Exterior Panels  
The front and side panels are durable stainless  
steel. Fingerprints, dust and grease will require  
cleaning with a good quality stainless steel cleaner.  
Water filters  
If the machine has been connected to water filters,  
check the cartridges for the date they were  
replaced or for the pressure on the gauge. Change  
cartridges if they’ve been installed more than x  
months or if the pressure drops too much when the  
ice machine fills with water.

What to do before calling for service  
Reasons the machine might shut itself off:  
Lack of water.  
Freeze cycle takes too long.  
Harvest cycle takes too long.  
High discharge temperature.  
Controller self test failure.  
Check the following:  
1. Has the water supply to the ice machine or  
building been shut off? If yes, the ice machine will  
automatically restart within 25 minutes after water  
begins to flow to it.  
2. Has power been shut off to the ice machine? If  
yes, the ice machine will automatically restart when  
power is restored.  
3. Has someone shut the water off to a water  
cooled unit? If yes, the ice machine may need to be  
manually reset.  
4. Is the curtain open because some ice is stuck  
under it? If so, remove the ice and the machine  
should start in a few minutes.  
Note: Curtain can be removed & replaced anytime  
the machine is in a standby mode or when it is in a  
freeze cycle. Removal of the curtain during harvest  
terminates harvest at that point and, if left off, will  
result in the machine shutting off.  
Check For  
Ice Stuck  
Under Curtain  
To Manually Reset the machine.  
Push and release the Off button.  
Push and release the On button.  
To Shut the Machine Off:
