Scotsman CU3030MA-1 Prodigy Series 30" Air Cooled Undercounter Medium Cube Ice Machine - 313 lbs.

If a malfunction occurs, a machine must be back in service fast. A special feature of Prodigy ice machines assures that problems are quickly found and corrected. When a machine is making ice normally, the function lights in the upper left-hand corner are out. However, when a problem arises—like in this case where there is a problem with the water fill--a status light blinks red and the machine shuts down. The water solenoid valve automatically opens and tries to refill the reservoir. If it succeeds, the warning light goes out and the cycle continues. The controller will repeat water fill attempts every 20 minutes until successful or until a manual intervention. If these attempts fail, the machine remains shut down and the front panel must be removed to find the source of the problem. This reveals the controller that can guide the technician to the cause of the problems. If the machine were working properly, the code display would show 1 of 3 codes. F shows a free cycle is underway. H shows that the harvest cycle is on. B shows a full bin of ice is ready. However, now the display shows a number 3, telling the technician that there is a slow water fill. At this point, he might want to know if this problem has happened before. He can find this information out by pressing the off button for 3 seconds and then repeatedly pressing the manual harvest button that shows, in sequence, the previous problems. In this case, the recent problems have been slow water fill which is shown by repeated a repeated code 3. For the sake of illustration, the technician could also see any other problems that the machine had in the past. For example, if code 1 appeared, it would indicate a past problem with slow freeze time. A code 2 would represent a slow harvest time. A code 4 would be a high discharge temperature. A code 5 would be a temperature sensor failure. A code 7 would be a discharge temperature sensor failure and code 8 would be a short freeze cycle. In this case, however, the problem is slow water fill, so the technician reads the indicator lights that show which components are operating at any stage of any cycle. In this case, he may press "on" to start the initial startup cycle. In the starting stage, the water pump light, the purge valve light, the water solenoid light, the sump empty light, and the curtain switch light come on. The water pump light shows that the water pump is working. The purge valve light shows a purging reservoir. The water solenoid light shows that the machine is trying to refill the reservoir. The sump empty light indicates an empty reservoir and the curtain switch light shows that the curtain is closed. The technician now begins zeroing in on a cause. First, he makes sure of adequate water pressure and then checks each component to verify that they are all working. In this case, he may find a water solenoid that needs replacing. In the same way, the indicator lights can lead him through every stage of every cycle. The technician sees which components should be operating which enables him to quickly find and correct the source of any problem. The result is that the technician has a diagnostic path leading to the right solution in quick time! Added up, the leading qualities of Prodigy ice machines have a longer and trouble-free service at a lower cost with greater flexibility, starting with the stingiest energy consumption in the industry that translates into lower utility costs. A control panel with auto indicator lights that signal the need for service before emergencies arise and point the way to early solutions. Water sends automatic adaptive purge controls to fight scale buildup, earning longer intervals between scale removals. An optional ultra-sonic ice level control reduces ice levels in the bin, ensuring fresh, easy-to-handle ice. An optional Prodigy smart board advanced controls display data on-scene or transmitting to a remote computer for early alert and fast diagnosis of operating issues. The same control, paired with the very smart ice level control, can be programmed to match ice levels to varying day-to-day needs with no monitoring needed. Plus, there's an optional Smart-Lock remote lockout control that enables leasing companies to switch the machine on and off to encourage timely lease payments. Introducing the Prodigy line of cube ice machines--easy to service, repair, and maintain. Recommend Scotsman ice machines to customers with confidence. They'll love the performance and you'll love how simple it is to accurately diagnose and fix problems. Get ready to think smart! The Prodigy is here.

The ice system requires 3 types of maintenance. They are scale removal, sanitizing, and filter and condenser cleaning. To remove scale, remove the evaporator cover of the harvest and push the "clean" button which drains and refills the reservoir. Then, circulate Scotsman's scale remover for at least 10 minutes. Push and release the "clean" button to drain and refill the reservoir for at least 20 minutes to purge the cleaner and residue. When done, push the "off" button. Then, remove the curtain, the ice-thickness sensor and the water distributor, making sure all distributor holes are open. Wash all of these parts with a solution of scale remover and water. Do the same thing with the water level sensor. Then, thoroughly wash these components in a solution of sanitizer and return them to their original positions. Using the same solution, wash the inside of the freezing compartment, including the evaporator cover and right-side panel. Push and hold the "clean" button to drain the reservoir. Push and release the "clean" button again, and when the "purge valve" indicator light goes out, immediately pour the remainder of the solution into the reservoir and let it circulate for 10 minutes. Then, push and release the "clean" and let the machine drain and repeatedly refill the reservoir for at least 20 minutes to purge the sanitizer and residue. When you're done, push the "off" button. Finally, reinstall the evaporator cover and front panel. To resume ice making, push and release the "on" button. As a last step, pull the reusable air filter from the side panel. Wash it using a mild detergent and reinsert it into the side panel. We strongly recommend never operating the machine without a filter except when cleaning. The condenser itself can be cleaned only by a refrigeration technician.
