Location Limitations:
The product is designed to be installed indoors, in a controlled environment. Air cooled models discharge very warm air into the room. Water cooled models discharge warm water into the building’s drain. Space needs to be provided for service access.
Space Limitations
Do not block air flow at the front.
In most cases, CU3030 air cooled models installed without legs or casters will experience reduced ice making capacity.

Room Temp Air In
Air Flow - Do Not Restrict
Airflow for air cooled models is in the front left and out the front right; CU3030 air cooled models also take air in from the bottom of the cabinet
Built In Situations:
•If built in under the counter with no space above, the bin cannot be removed without moving the unit.
•If built in with 1" or more clearance above the unit, the bin can be removed without moving the unit.
•If built in with between 1/2 and 1 inch of clearance, releasing the top panel's back flap prior to placement will allow removal of the bin without moving the unit.
The warranty statement for this product is provided separately from this manual. Refer to it for applicable coverage. In general warranty covers defects in material or workmanship. It does not cover maintenance, corrections to installations, or situations when the machine is operated in circumstances that exceed the limitations printed above.
Product Information
The product is a self contained cuber with bin. That type of machine is designed to be free standing or it can be built in under the counter.
Options
Casters may be used in place of the supplied legs, the kit number is KBC1.
When not using legs or casters, most codes require sealing to the floor. Kit numbers to allow sealing are KPUFM26 and KPUFM30.

Table notes: Height is without legs. Medium cube models have the same electrical characteristics as Small. Series revision code omitted. * Or HACR type circuit breakers.
** If not using legs, add .25" for screws below base. Legs add 6 to 6.75 inches, but not the 1/4 inch for the screws. Use of floor mounting kit adds about a half inch.

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. Water can contain impurities either in suspension or in solution. Suspended solids can be 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.
RO water. This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no less than 10 microSiemens/cm.
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 reservoir to keep it cleaner between manual cleanings.
This manual covers several models. The model number on the product is located in two places, on the back dataplate and on the model and serial number tag, located behind the front panel. See the illustration for the dataplate and serial tag locations.
Write the model and serial number of this product here:
Water purge
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 purge, and an effective purge can increase the time between needed water system cleaning.
In addition, this product has the capability to automatically vary the amount of water purged based on the purity of the water supplied to it. The water purge rate can also be set manually. Adjustments of purge due to local water conditions are not covered by warranty.
Uncrate and Set Up
Remove the carton, and using part of the carton as a cushion, tip the unit on its back to remove the skid and attach the legs or casters.
If installing the optional kit to attach the unit to the floor, see that kit's instructions. If placing on the floor without using that kit, position field supplied furniture glide pads under the unit to reduce floor scratches from the metal on the bottom of the unit.
Return the unit to an upright position. Do not start the unit for at least an hour after it has been returned to the upright position.
Place the ice machine in the selected location and level it by adjusting the bin leg levelers.
