CME1056 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. Be certain that the information applies to the model in question. If no model is listed, the information applies to all models. 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.

It will operate satisfactorily under a wide variety of conditions. 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. In addition, there may be other bins that can be used, check Scotsman's sales literature for application information.

Do not place Air Cooled models where the noise from the fan will be objectionable. 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, near the purge valve. 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 also have treatment in them for dissolved solids. Check with a water treatment service for a recommendation. Nameplate on Back Panel 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, Note: Slope front bins must have an internal baffle. combined with water filters, prolongs the times Scotsman HTB555 and BH550 have the required between needed water system cleaning. baffle. Baffle must be approximately in the position 3 shown in the diagram. Note: All Scotsman CM models, like those described in this manual, feature Scotsman's AutoIQTM control system and ReliaCleanTM water Baffle system cleaning process. Service Technicians: All models covered here come set from the factory at a "standard" water rinse, which is compatible with typical water conditions. They may be adjusted to "Minimum" or "Maximum" 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.

Do not place them where the heat and noise will be objectionable. A 6 inch MINIMUM clearance on the back, and both sides is required for the basic operation and service of the air cooled model.

Use baffle for In-The-Corner Applications Back View of Ice Machine Air Cooled Condenser Outlet Attach Air Baffle Here Airflow is in the sides and out the back Air Baffle Attach Air Baffle Here Baffle Position Baffle Baffle Note: A six inch side clearance with zero top clearance will NOT provide enough air exchange space for optimum performance. 12 inches side clearance is required when there is no top clearance. 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. Ice Machine Top View Ice Machine Top View Ice Machine Top View Wall Wall Wall 17-2632-01 Rev. A. Air cooled models come equipped with a baffle that can be used when the machine is installed in a corner. The purpose of the baffle is to limit air recirculation. This can occur in a corner when the hot air from the back of the machine is re-drawn back into the machine from the nearest side of the machine. Return the bin to an upright position. Check the bin top gasket for gaps and tears, fill any in with food Install the air baffle as shown.

Remove the carton from the skid. After removal of the shipping straps, 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). May 2000 Page 6 CME1056 Cabinet Panel Removal: Note: The top panel holds the upper edges of the side panels in place. 1. Remove the front panel by removing the two screws connecting the top edge of the front panel to the machine, then pull out at the bottom. 2. Lift up at the front edge and push the top panel back until it releases from the tabs connecting it to the back panel. 3. Remove the screws at the front edge of the left side panel, and pull forward until it releases from the tabs connecting it to the back panel. Remove The Front Panel First May 2000 Page 7 CME1056 Stacking: Requires Kit Only like models may be stacked. Begin after the Upper Machine: bottom unit has been placed on the ice storage bin and secured. Stacking requires heavy duty leg kits. 8. Knock out 1 hole in the lower left (viewed from the front) corner of the upper unit's back panel. Casters are NOT recommended. Bottom Machine: 1. Remove front, side, and top panels. 2. Hang the plastic shield from the tabs on the stainless steel bracket. 3. Locate the two notches on the sides of the top edge of the freezing compartment. Lower Unit: 9. Knock out 1 hole in the upper left (viewed from the front) corner of the lower unit's back panel. 10. Position the strain reliefs over the wrapped portion of the stacking kit wire harness. 11. Route the Stacking Kit wire harness from the back to the top and bottom machines thru the holes made in steps 8 and 9. The harness is marked which end goes to which machine. Push the strain reliefs into place from the back of the machines. Follow local codes for 24 volt wire 12.Route wire harness in lower ice machine to the controller. Connect to terminal #7. Plug the two free wires onto thermostat terminals #1 and #2 Notch 4. Place the bracket over the notches of the freezing compartment. Bracket Routing of Harness Shield 5. Secure bracket to freezing compartment with screws from the kit (from the sides). 6. Locate gasket material in kit. Place a layer of gasket material on the top edge of the plastic freezing compartment. 7. Place the top ice machine onto the bottom one. Secure together with hardware from the top machine. Remove front and left side panels. Ma ...
