Installation: Product Specications
Location Limitations: The product is designed to be installed indoors, in a controlled environment. Air cooled models discharge very warm air into the room out the back. Space must be allowed at the left side and back for air intake and discharge.
Water cooled models discharge warm water into the building’s drain. Space needs to be provided on both sides and above for service access.
Space Limitations - Affects Ice Making Capacity
Note: Although the machine will function, ice capacity
of air cooled machines will be signicantly reduced
with minimal clearance at the sides, back and top. Some space is recommended for service and maintenance purposes on all models.
6" of space at the sides and back are required for adequate operation. To get the most capacity, locate the machine away from heat producing appliances and heating ducts. Provide several feet of space to
the left for maximum ice capacity.
Walls or other large machines near to the ice machine might also cause a reduction in ice capacity. One foot behind and two feet above will be required to make rated capacity.

Water
The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product. There are two ways water can contain impurities: in suspension
or in solution. Suspended solids can be ltered out. In solution or dissolved solids cannot be ltered, they must be diluted or treated. Water lters are
recommended to remove suspended solids. Some
lters have treatment in them for suspended
solids. Check with a water treatment service for a recommendation.
Scotsman lters:
A triple head lter is recommended for the potable water. Either the Scotsman SSM3 taste and odor lter
system, or the ADS-AP3 Aqua Patrol system. RO water. This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm.
Condenser Water Supply - ltration not recommended
for this water supply
GPH, 70 degree water
C1448W 70 C1848W 106
Potential for Airborne Contamination
Most water lters remove chlorine from the water
supply to the machine which contributes to this
situation. Testing has shown that using a lter 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
Water Flush
Cube ice machines use more water than what ends up in the bin as ice. While most water is used during ice making, a portion is designed to be drained out every cycle to reduce the amount of hard water scale
in the machine. That’s known as water ush, and an effective ush can increase the time between needed
water system cleaning.
In addition, this product is designed to automatically
vary the amount of water ushed based on the purity of the water supplied to it. The water ush rate can
also be set manually.
Adjustments of ush due to local water conditions are
not covered by warranty.
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.

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.
Note: Turn the leg levelers in all the way and adjust after the ice machine is on top and in its selected location.
Return the bin to an upright position. Check the bin
top gasket for gaps and tears, ll any in with food
grade sealant prior to placing the ice machine on the bin.
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).
Open door to access On and Off switch buttons.
Lower Light and Switch Panel
This user accessible panel provides important operational information and duplicates the lights and switches on the controller. It also allows access to the On and Off buttons that operate the ice machine.
Level the bin and ice machine using the adjustment part of the legs.
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:
• The used bin must be in good condition. Broken
doors, hinges, or warped walls are reason for considering a new 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.
Sometimes access to the switches should be limited to prevent unauthorized operation. For that purpose
a xed panel is shipped in the hardware package. The xed panel cannot be opened.
To install the xed panel:
1. Remove the front panel and remove the bezel.
2. Spread the bezel frame open and remove
original door, insert xed panel into bezel. Be
sure it is in the closed position.
3. Return bezel to panel and install panel on unit.

Drains
All models require drain tubing to be attached to them.
Air cooled models have a single ¾” FPT drain tting
in the back of the cabinet. Water cooled models have
the same tting plus an additional ½” FPT drain tting
in the back of the cabinet. 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.
1. Connect water supply to water inlet ttings.
Note: This NSF listed model has a 1" anti-back
ow air gap between the end of the water inlet tube
and the highest possible reservoir water level, no
additional back ow device is required for the potable
water inlet.
2. Connect drain tubing to drain ttings.
Water Inlet Connection
3. Route the drain tubing to building drain. Follow local codes for air gap.
Use rigid drain tubes and then route them separately – do not Tee into the bin’s drain or, if water cooled, Tee the condenser drain into the reservoir or bin drain.
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.
Horizontal runs of drain tubing need a ¼” per fall per
foot of run for proper draining. Follow all applicable codes.

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 lters 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 specically 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.
1. Remove the front panel.
2. Remove the evaporator cover.
3. Remove all ice from the storage bin or dispenser.
4. Push and release the Clean button. The yellow Clean light will blink and the display will show C. The machine will harvest any ice, drain the
reservoir and begin to rell it.
Note: Curtains must be in the closed position. Move curtains to release any ice trapped after ice is harvested.
5. Observe code display, when it blinks the characters “A d 1” immediately go to the next step.
6. Pour 24 ounces of Scotsman Clear 1 ice machine scale remover into the reservoir. The unit will
circulate the scale remover, then drain and ush
it. This will take 35 minutes, then the machine will stop and the display will show O.
Ice machine cleaner contains acids. Acids can cause burns.
7. Mix a cleaning solution of 1 oz of ice machine scale remover to 12 ounces of water.
8. Locate curtains, push in on edge of curtain by pivot pin to release it. Pull curtains out of machine.
9. Remove water distributors from ice machine. Remove cover, inspect distributor for restricted
orice holes, ush out any debris and open any
restricted holes. Return cover to distributor, be sure it is fully attached.
10. Locate ice thickness sensor. Squeeze mounting legs together to release sensor.

Air cooled condenser lter
1 Pull air lters from their louvered mounts.
2 Wash the dust and grease off the lter.
3 Return them to their original positions.
Do not operate the machine without the lter in place
except during cleaning.
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 lters
If the machine has been connected to water lters,
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 lls
with water.
Maintenance
Air cooled condenser
If the machine has been operated without a lter the air cooled condenser ns will need to be cleaned.
Push and release the Off button. Wait until the machine stops.
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 ns. Use a n comb to straighten any bent ns.

Under Curtain
Air and Water Cooled User Manual 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 ow 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.
To Manually Reset the machine.
Open the switch door
Push and release the Off button.
Push and release the On button.
To Shut the Machine Off:
Push and hold the Off button for 3 seconds or until the machine stops.
