CME2006R 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. This machine incorporates advanced technology, including a scroll compressor. 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. All Scotsman CM3 models, like this one, feature Scotsman's AutoIQTM control system and ReliaCleanTM water system cleaning process. TABLE OF CONTENTS Introduction . . . . . . . . . . . . . . . . . .

CME2006R Specifications Both of these ice machines are designed to be installed indoors, in a controlled environment. They can operate satisfactorily under a wide variety of conditions. However, 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. Bins: All models will fit a standard, 48" wide or wider open top Scotsman Ice Storage Bin. Some examples are: Operational Limits Minimum Air Temperature Water Temperature Water Pressure Voltage (60 Hz) 50oF. 40oF. 20 psi 197 Maximum 100oF. 100oF. 80 psi 253 · · · · BH900 BH1100 BH1300 BH1600 In addition, there may be other bins that can be used, check Scotsman's sales literature for application information. Note: Slope-front bins must have an internal baffle. Scotsman's BH900 haas the required baffle. Baffle must be approximately in the position shown in the diagram below. Baffle Voltage note: The control system transformer in the control box of this ice machine has two primary taps, one for 208 volt power and one for 240 volt power. The machine ships with the power supply connected to the 208 volt tap. Change to the 240 volt tap when the voltage supplied to the unit is greater than 229 volts. 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.

Electrical: Check the nameplate for electrical requirements. The nameplate is located on the back of the ice machine. If the information on the nameplate is different from other published information, go by the nameplate data. While the model and serial number are on the nameplate, a serial number plate is located at the front of the machine, behind the left front panel and to the right of 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 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. Service Technicians: All models covered here come set from the factory with at a "Standard" water rinse. Standard water rinse is designed to be compatible with typical water conditions. The ReliaCleanTM water system provides an adjustment method so the amount of water rinsed out of the machine 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. Nameplate Serial Number Plate July 1998 Page 4 CME2006R Location & Assembly Locate the ice machine indoors. A 6 inch minimum Cabinet Panel Removal: clearance on the back and left sides is required 1. Remove the front panels by removing the four for the proper operation and service of this screws connecting the front panels to the machine. machine. Locate the remote condenser as close as possible to the ice machine. See page 11 for details. 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. Note: If recycling a prior bin, be sure that the bin top gasket is in good condition or seal the ice machine to the bin with food grade sealant. Level the top edge of the bin front to back and left to right. If the ice machine has not been unpacked, do so now. Remove the carton from the skid. Remove shipping straps. Remove the left side and front panels. Remove all packaging materials including the compressor shpping brackets.. 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. 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 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. Evaporator Cover: To Remove Evaporator Cover: Push Up and Tilt Out November 2003 Page 5 CME2006R Bin Control: Installation The bin control is a thermostat. It must be field Note: If the machine is located at an altitude installed after the ice machine has been placed on higher than 2,000 ft., adjust the thermostat by the bin. removing the plastic cover and rotating the adjustment screw per the table. Before starting, remove the left front panel and any baffle in the bin. 1. Locate bin thermostat bulb. 2. Route bulb thru routing tube (located between the compressor and the reservoir). 3. Locate bin thermostat bracket. 4. Carefully position the thermostat bulb on the bracket (see the diagram on the next page). 5. Fasten the bracket to the bottom of the ice machine with the two 3-pronged knobs supplied with the unit. 6. Pull back into the ice machine any excess capillary tubing. 7. Return the baffle to the bin and continue with the installation.
