December, 1994 Page 1 CME865W & CME1002W SPECIFICATIONS Before beginning installation, be sure that all of the components necessary for complete assembly of the ice system are available, and are the correct components with regard to model, voltage, and finish. A stacking kit (KSCMS) is required for stacking CME1002 or CME865 ice machines. It interconnects the sonar bin ice level controls. A CME865 or CME1002 may only be stacked onto models CME865, CME1002, MCM1062 or CMS1002. The CME865 or CME1002 will fit any current 30" wide Scotsman bin, such as the BH550 or HTB555, without needing a bin top. Other bins will require a bin top. Note: The sonar transducer, located in the base of the machine, must NOT be covered by installation material (such as a non-Scotsman bin top). The transducer must have clear access to the ice to be able to sense the ice level.

Minimum Air Temp Water Temp Water Pressure Voltage 50 F. 400F. 20 PSI 197 0 Water Limitations An ice machine is a food manufacturing plant; it takes a raw material, water, and turns it into a food product, ice. The purity of the water is very important in obtaining pure ice and in maximizing product life. These general recommendations should help keep the ice maker clean: 1. Filter the water used to produce ice. Water filters vary greatly in ability and function. Install one that filters out suspended solids to a dimension of 5 microns or smaller. The finer the filter the better, but finer filters will clog sooner than course ones. It may be necessary to add a course filter ahead of the fine filter to prolong filter life. 2. Check with a water treatment specialist for a water test, and recommendations regarding filters and treatment. When servicing a machine, it's helpful to compare that unit's operating characteristics to those of a new, clean, normally operating machine. What follows is that type of information: Service Limitations Some space on the sides, the back and the top should be allowed for service and utility connections. Maximum 1000F. 1000F. 80 PSI 253 Operating the ice machine outside of the above limitations, or outdoors, is potentially damaging to the machine; also it is misuse of the machine, which may void the warranty.

A SERIAL NUMBER PLATE IS LOCATED BEHIND THE FRONT PANEL, NEAR THE CONTROL BOX. December, 1994 Page 5 CME865W & CME1002W FOR THE INSTALLER: Machine & Bin Assembly Overview: This ice system is comprised of 2 major assemblies: 1. The ice storage bin. 2. The ice maker itself. Storage Bin: After uncrating the ice storage bin, attach the legs to the bin: 1. Use a portion of the carton as a cushion, and tip the storage bin on its back. 2. Screw the legs into the threaded holes in the bottom of the bin. 3. Turn the leg levelers all the way in to prepare the bin and ice machine for leveling. 4. Return the bin to the upright position. Ice Maker: 1. Arrange for proper electric, water and drain. See instructions for the plumber and for the electrician. 2. Position the ice storage bin in the selected INDOOR location. 3. Level the bin, in both the front to rear and side to side directions. 4. Inspect the bin top mounting gasket which should be flat, with no wrinkles, to provide a good water seal when the cuber is installed on top of the bin. 5. Install the modular cuber on top of the bin using care to be sure a good seal is made between the two cabinets, use of a mechanical lift is recommended. Align the holes in the bottom back of the cabinet to mate with the two mounting straps on the top rear of the bin. 6. Use bolts and straps found in the hardware package to secure the ice machine to the ice storage bin. When alignment and leveling are completed, tighten the bolts to secure the mounting straps. December, 1994 Page 6 CME865W & CME1002W FOR THE PLUMBER Water Supply The recommended water supply line is a 3/8-inch O.D. tubing with a minimum operating pressure of 20 PSIG and a maximum of 80 PSIG. A separate water inlet is required for the condenser water supply. Connect to cold water supply line with standard plumbing fittings, with shut off valve installed in an accessible place between the water supply and the cuber. In some cases a plumber will be required. CONFORM TO ALL LOCAL CODES Drain Connections: Connections: All drains are gravity type and must have a minimum of 1/4 - inch fall per foot of horizontal run. The drains to be installed must conform with the local plumbing codes. Install a vertical open vent on the ice machine reservoir drain. The ideal drain receptacle is a trapped and vented floor drain. The storage bin drain should be insulated. Water Cooled Connection: A separate cold water supply is required, connect to the 3/8-inch FPT fitting at the back of the cabinet. An additional drain line is required to drain the water cooled condenser, and must not interconnect to any of the other drains. CONDENSER INLET HAND SHUT OFF VALVE RESERVOIR DRAIN VENT CONDENSER DRAIN HAND SHUT OFF VALVE POSITION OF FILTER BIN DRAIN VENT WATER COOLED PLUMBING CONNECTIONS FLOOR DRAIN December, 1994 Page 7 CME865W & CME1002W FOR THE ELECTRICIAN: Electrical Connections See the NAMEPLATE for current requirements to determine wire size to be used for electrical hookup. The cuber requires a solid chassis to chassis earth ground wire. See Wiring Diagram. Be certain the cuber is connected to its own electrical circuit and individually fused. Voltage variation should not exceed ten percent of the nameplate rating, even under starting conditions. Low voltages can cause erratic operation and may be responsible for serious damage to the icemaker. Electrical connections are made at the rear of the icemaker, inside the junction box. All external wiring should conform to the national, state and local electrical code requirements. Usually an electrical permit and services of a licensed electrician will be required. ELECTRICAL JUNCTION BOX FUSES or HACR CIRCUIT BREAKERS December, 1994 Page 8 CME865W & CME1002W FOR THE INSTALLER: Final Check List 1. Is the ice maker cabinet in a room where ambient temperatures are within the minimum and maximum temperatures specified? 2. Is there clearance at both sides of the cabinet and at the back and top for service and utility connections? 3. Has water supply pressure been checked to insure a minimum of 20 PSIG and a maximum of 80 PSIG operating pressure? 4. Is the cabinet level? 5. Check that any shipping material has been removed from inside the cabinet. 6. Have all electrical and piping connections been PROPERLY made? 7. Are the Master and Compressor switches on OFF? 8. Has power been connected to the ice maker? 9. Is the water supply line shut off valve installed? 10. Check all refrigerant lines and conduit lines, to guard against vibration or rubbing and possible failure. 11. Have the bin and cabinet been wiped clean and sanitized? 12. Has the Customer Evaluation & Warranty Registration form been properly filled out? Check for correct model and serial numbers from Serial nameplate, then mail the completed form to SCOTSMAN. 13. Has the owner been given the name and telephone number of the authorized SCOTSMAN Service Agency serving him? December, 1994 Page 9 CME865W & CME1002W INITIAL START UP Ice Maker: 1. Remove front panel. 2. Remove two screws and the control box cover. 3. Remove the evaporator cover. 4. Remove the left side service panel. 5. Check that the ON/WASH/OFF rocker switch and the Compressor ON-OFF toggle switch are in the OFF position, on the control box. 6. OPEN the water supply line shut off valve. 7. Inside the control box is the shaft of the timer and the switch assembly. Rotate the shaft of the timer and switch assembly clockwise to where the actuator arm on the microswitch drops off outer cam into cam slot. See Timer Cam Positions. TIMER CAM POSITIONS MICRO SWITCH 9. Observe water fill cycle: The water pump will be operating and the water inlet solenoid valve will OPEN. Incoming water flows from the valve through the tubing, the reservoir fills and excess water drains out the machine drain. At the end of the harvest cycle the water inlet solenoid valve will close and the water fill cycle is complete. If the reservoir is not full, turn the shaft of the timer clockwise into a new harvest cycle; this opens the water valve again. The water pump forces water from the reservoir up to the water distributor at the top of each evaporator plate, where water is dispensed, cascades down both sides of the evaporator plate and drains back into the reservoir for recirculation. 10. Check that the water cascades down over the cube molds and into the reservoir. Note: Some spray is normal on new machines. 11. When the reservoir is full, move the compressor ON-OFF switch to the ON position. 12. Check operation of the freezing cycle: Very shortly ice begins to form in the cube cells, and tubing becomes frosted at the top of the evaporator plate. Freezing time will be longer than average for the first cycle.. Average complete cycle time is about 14 - 16 minutes. 13. ...
