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. Some examples are: · BH550; HTB555; HTB350; HTB250 The CME256 and CME506 are the typical models used in hotel applications and they fit the Scotsman HD30 dispenser without an adapter. All models fit the ID200 or ID250 dispensers which require a KBT44 adapter. Check Scotsman's sales literature for other application information. Note: These machines fill the bin very full, up to the base of the ice machine. Bin Model BH800 may need kit KBaffle2 and Bin Model BH550 may need kit KBaffle1. In some cases the ice level in the bin may be too high for a customer's needs. A thermostat kit is available to lower the ice level, its part number is A37749-001. A stacking kit, for like models, is KSCME6-30. Scotsman reserves the right to make design changes and/or improvements at any time. Specifications and designs are subject to change without notice. Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman that have been altered in any way, including the use of any parts and/or other components not specifically approved by Scotsman.

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. There are two ways water can contain impurities: in suspension or in solution. Suspended solids can be filtered out. In solution or 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 are set by the factory at a "standard" water rinse, which is compatible with typical water conditions. The ReliaCleanTM water system provides an adjustment method so to the amount of water rinsed per cycle can be changed. 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. Top View Diagram Location of Nameplate (on the back, plus a serial plate is behind the front panel) Nameplate Back View Diagram (air cooled) Note: Although the machine will function, ice capacity of air cooled machines will be significantly reduced with only 6 inches of clearance at the sides, back and top. July 2004 Page 3 CME256, 506, 656, 806: AutoIQTM Cubers Location & Assembly: Air cooled models take room temperature air in from the left and right sides, and discharge warm air out the back. If installed in a corner or with another cabinet next to the right side, an air baffle could be installed on the back of the cabinet to minimize air re-circulation. A 6 inch minimum clearance on the back, left and right sides is required for operation and service of this machine. Air Flows in the Sides and Out the Back 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 front panel to the left and right sides. Remove Second Remove First Note: Although the machine will function, ice capacity of air cooled machines will be significantly reduced with only 6 inches of clearance at the sides, back and top. Removal of Panels 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. Front Panel "C thru F" Series: Remove top two screws, and pull the bottom of the panel away from the machine to unsnap it from the machine. 2. Remove 2 screws at the front edge of the top panel, and pull the top panel forward until it releases from the tabs connecting it to the back Return the bin to an upright position. Check the bin panel. top gasket for gaps and tears, fill any in with food 3. Remove the screws at the front edge of each grade sealant prior to placing the ice machine on side panel, and pull them forward until they the bin. release from the tabs connecting them to the back panel. 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).

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). 4. Fasten the upper cabinet to the lower cabinet with the hardware (two metal straps and four bolts) provided with the machine. 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 Controller. Tape any excess wire to the insulated suction line. In the upper unit, route the harness thru the snap bushing just below the System Controller. Plug one end into each Controller connection number 7. Wire Harness from 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.
