CME506R, 656R, 806R: AutoIQ Cubers Introduction: This product manual contains the information needed for the setup, installation, initial start up, sanitation and maintenance of this ice machine. Keep it for future reference. There are 3 models covered in this manual: Be certain that the information applies to the model in question. If no model is listed, the information applies to all models, including A and D series. This manual is organized in the same way as the expected use of the machine, it begins with specifications, goes thru unpacking and setup, shows where everything is; continues with initial start up, then describes how it works. After that is the sanitation section, followed by service diagnosis and repair. Additional Maintenance . . . . . . . . .

They can operate satisfactorily under a wide variety of conditions. However, Do NOT operate the machine where it has not been designed for. Do NOT operate the machine in temperatures it has not been designed for. Do NOT operate the machine above or below the voltage limits for the particular model. Do NOT operate the machine with too little or too much water pressure. All models will fit a standard, 30" wide Scotsman Ice Storage Bin.

Use precharged tubing kits, RTE25 (25') or RTE40 (40'). A stacking kit to place two like cubers together is: KSCME6-30. March 2002 Page 2 CME506R, 656R, 806R: AutoIQ Cubers Pre-Installation Other Applications: The Electronic Cubers may be placed on certain Ice Dispensers, including Scotsman models: HD356, RS220 and IS220. Check with other dispenser manufacturers for recommendations regarding application. Check the nameplate for electrical requirements. The nameplate is located on the back of the ice machine. While the model and serial number are on the nameplate, a serial number plate is located at the front of the machine, below the metal control box. Water: There is no such thing as pure water. All water contains some impurities. There are two ways water carries the impurities: suspended and dissolved. Suspended solids can be filtered out. Dissolved solids 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. 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 "rinse" out the water system to keep hard water scale from clogging up the machine. That water rinse, combined with water filters, prolongs the times between needed water system cleaning. Note: All Scotsman CM3 models, like those described in this manual, feature Scotsman's AutoIQTM control system and ReliaCleanTM water system cleaning process. Service Technicians: All models covered here come set from the factory with at a "Standard" water rinse. Standard water rinse is designed to be comparable with typical water conditions. The machine may be adjusted to a different water rinse after start up. If the prior ice machine worked acceptably well with the local water conditions, leave the machine at the factory setting. If severe water conditions are present, and water filters do not solve the problem acceptably, adjust the machine to use more water. If water conditions are excellent, adjust the machine to use less water. See the Adjustments section. Note: Water use adjustments are customer convenience adjustments; they are NOT factory defects and are NOT covered by warranty. January 2000 Page 3 Nameplate CME506R, 656R, 806R: AutoIQ Cubers Location: A 6 inch minimum clearance on the back, left and right sides is required for the proper operation and service of this machine. Locate the condenser as near as possible to the interior location of the ice maker. Cabinet Panel Removal: Note: The top panel holds the upper edges of the side panels in place. 1. Front Panel, "A" series: Remove the front panel by removing the four screws connecting the Select the best available location, one that protects front panel to the left and right sides. the condenser from extremes of dust, grease and sun. Meet all applicable building codes. Unpacking and Assembly: 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: Stacked applications may not use casters. 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. 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. Secure the ice machine to the bin with the hardware provided (two metal straps and 4 bolts). After all packing materials have been removed from the ice machine, lift or hoist the machine onto the bin. Align the sides and back of the machine with the sides and back of the bin. Secure the ice machine to the bin with the two metal straps and 4 bolts provided. Panel Removal Remove First Remove Second Front Panel "C and D" Series: Remove top two screws and pull the bottom of the panel away from the machine to unsnap it from the machine. 2. Lift up at the front edge and pull the top panel forward until it releases from the tabs connecting it to the back panel. 3. Remove two screws at the front of each side panel, and pull them forward until they release from the tabs connecting them to the back panel. January 2000 Page 4 CME506R, 656R, 806R: AutoIQ Cubers Stacking: Models CME256, CME506, CME656 and CME806 may be stacked together in any combination. Use kit number KSCME6-30. 1. Remove the front, left side and top panels from the bottom machine. Discard the top panel. 2. Remove the front and left side panels from the top machine. 3. Place the upper machine onto the lower machine. Check that the tabs on the top of the freezing compartment in the lower machine engage the slot in the base of the upper machine (around the cube port). Mounting Strap Strain Relief 4. Fasten the upper cabinet to the lower cabinet with the hardware (two metal straps and four bolts) provided with the machine. Stacking Kit Wire 5. Knock out 1 hole in the upper left (viewed from the front) corner of the lower unit's back panel. Knock out the hole in the lower left (viewed from the front) corner of the upper unit's back panel. 6. Position the strain reliefs over the wrapped portion of the stacking kit wire harness. Route the Stacking Kit Wire Harness from the back to the top and bottom machines thru the holes made in step 5. The harness is marked which end goes to which machine. Push the strain reliefs into place from the back of the machines. Follow local electrical codes for 24 volt wire. In the lower unit, route the wire behind the suction line and thru the snap bushing just below the AutoIQ Controller. Tape any excess wire to the insulated suction line. In the upper unit, route the harness thru the snap bushing just below the Controller. Plug one end into each Controller connection number 7. 7. Place insulation pad from the kit over the reservoir drain tubing in the upper machine. Make certain that the insulation is in contact with the tubing. 8. Return all panels to their normal places. Mounting Strap Harness Stacking Two Ice Machines Together January 2000 Page 5 CME506R, 656R, 806R: AutoIQ Cubers Remote Condenser Location Use the following for planning the placement of the Configurations that do NOT meet these condenser relative to the ice machine requirements must receive prior written authorization from Scotsman. Location Limits - condenser location must not exceed ANY of the following limits: Do NOT: condenser is 35 physical feet · Maximum drop from the ice machine to the condenser is 15 physical feet · Physical line set maximum length is 100 feet. · Calculated line set length maximum is 150. Calculation Formula: · Maximum rise from the ice machine to the rises. · Route a line set that falls, then rises, then falls. Calculation Example 1: The condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally. 5 feet x 6.6 = 33. 33 + 20 = 53. This location would be acceptable Calculation Example 2: The condenser is to be located 35 feet above and then 100 feet away horizontally. 35 x 1.7 = 59.5. 59.5 +100 = 159.5. 159.5 is greater than the 150 maximum and is NOT acceptable. Condenser Distance & Location Schematic · Route a line set that rises, then falls, then · Drop = dd x 6.6 (dd = distance in feet) · Rise = rd x 1.7 (rd = distance in feet) · ...
