CME306 & CME456 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. Note: The ice machine will hang over the back of the Lancer dispensers shown in the following list. In addition, there may be other bins that can be used, check Scotsman's sales literature for application information. Note: This unit may not be stacked.

Do not place Air Cooled models where the noise from the fan(s) 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 controller. 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's BH375 has the required baffle. Baffle between needed water system cleaning. must be approximately in the position shown in the 3 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. Side View Serial Number Plate, Remove Front Panel to Locate January 2000 Page 5 4.0" 12.0" CME306 & CME456 Location Air cooled models take room temperature air in from the left side and discharge warm air out the back. Do not place them where the heat and noise will be objectionable. A 6 inch MINIMUM clearance between the back and a wall and between the left side and a wall or another product is required for the basic operation and service of the air cooled model. Airflow is in the left side and out the back Remove Air Baffle from its Shipping Position. Use baffle for In-The-Corner Applications Back View of Ice Machine Condenser Outlet Attach Baffle Here Air Baffle Baffle Position Ice Machine Top View Ice Machine Top View Baffle Wall Wall 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. 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. Install the air baffle as shown on the left rear corner when a side wall and back wall are between 6 and 18 inches from the unit. January 2000 Page 6 CME306 & CME456 On a Bin 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. Application Notes: No thermostat is required for any of the following bins. BH375: Direct fit. Connect ice machine to bin using strap and bolts from ice machine for the ice Return the bin to an upright position. Check the bin machine side, and sheet metal screws to attach top gasket for gaps and tears, fill any in with food the bracket to the bin. Use the bracket as a grade sealant prior to placing the ice machine on template and drill two holes in the back of the bin the bin. for the sheet metal screws. 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). HTB555: Use KBT27 BH550: Use KBT27 and Kbaffle1 Other Brand's Bins: KBT27 may allow installation of this unit on a non-Scotsman 30" wide bin. Thermostat kit KSTAT-22 must be used if the bin's baffle is too short. May 2004 Page 7 CME306 & CME456 On a Beverage Dispenser The CME306 or CME456 will mount on top of many brands of ice and beverage dispensers. The brands include Scotsman, Cornelius and Lancer. A bracket and filler plate kit (KLD22-30) is required to connect and secure the CME306 or CME456 to the Lancer 30" wide ice or ice and beverage dispenser. It includes a thermostat and bracket. Scotsman and Cornelius use the same adapter kits. 22" wide ice dispe ...
