PAGE 23 Parts Lists and Wiring Diagrams are Located in the Center of this Manual May 2000 Page 1 CME1356 and CME1656 Specifications These ice machines are designed to be installed indoors, in a controlled environment. They can 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. 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 All models will fit a standard, 48" wide Scotsman Ice Storage Bin. Some examples are BH900, BH1100, BH1300, BH1600. There may be other bins that can be used, check Scotsman's sales literature for application information. Slope front bins must have an internal baffle like the BH900. Baffle must be approximately in the position shown in the diagram on page 5. Scotsman reserves the right to make design changes and/or improvements at any time. Specifications and designs are subject to change without notice. Dateplates on the ice machine contain charge and electrical requirements. Always go by the dataplate information. The table below is for reference.

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 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 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. Nameplate Serial Number Plate Note: Slope front bins must have an internal baffle. Scotsman's BH900 has the required baffle. Baffle must be approximately in the position shown in the diagram. Baffle Side View May 2000 Page 5 4.0" 12.0" CME1356 and CME1656 Location & Assembly The air cooled models take room temperature air in from the left side and the front and discharge warm air out the back. A 6 inch minimum clearance on the back, and both sides is required for the proper operation and service of the air cooled model. 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 front panel to the machine. 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. 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. 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. 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). Locate the Bin Thermostat Bracket and hardware. Retain for later use. Aiir cooled: Remove baffle from its shipping position and secure to the back of the cabinet. Follow the directions on the baffle for proper installation. August 2003 Page 6 CME1356 and CME1656 Stacking - Kit KSCME6-LG-B Only like models may be stacked. Begin after the bottom unit has been placed on the ice storage bin and secured. Stacking requires heavy duty leg kits. Casters are NOT recommended. Note: Instructions are for either model. Bottom Machine: 1. Remove front panel, left side panel, and top panel. 2. Remove & discard top cover from over the freezing compartment. 3. Install gasket materials to freezing compartment: Cut about 22" of gasket material from the roll in the kit. Apply it to the back side top edge of the freezing compartment. Cut two lengths of gasket material to fit the right side top edge of the freezing compartment and apply them. 4. Place a bead of food grade sealant to the top of the back wall's gasket. 5. Place the shield bracket (has a large hole in the center) from the kit over the center of the freezing compartment. Insert the tabs of the bracket into slots on the back of the unit. 11. Remove two existing screws and secure the bracket to the: freezing compartment, back panel and front channel with the 2 existing screws and 1 large and 4 small screws from the kit. Both Machines: 12. Place the top ice machine onto the bottom one. Secure together with hardware from the top machine. Remove left front and left side panels. 13. At the back of the ice machines, on the compressor end, remove the upper knock-out from the bottom machine and the lower knock out from the upper machine. 14. Place a ...
