CME865R & CME1002R PRE-INSTALLATION INFORMATION These two models are modular ice cube machines that are designed to be connected to a remote condenser. The remote condenser coil must be of adequate size and must NOT have been used with a mineral oil refrigeration system. Specific Scotsman remote condensers are recommended. A stacking kit (KSCMS) is required for stacking these ice machines. It interconnects the sonor bin ice level controls. A CME865 or CME1002 may only be stacked onto models CME865, CME1002, MCM860, MCM1062 or CMS1002. These models will fit any 30" wide Scotsman bin, such as the BH550 or HTB555, without a bin top. Other bins 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. See page 5 for location.

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. 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. Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. They meet or exceed the standards of UL, NSF, and CSA. 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 part and/or other components not specifically approved by Scotsman. Scotsman reserves the right to make design changes and/or improvements at any time. Specifications and design are subject to change without notice. September, 1994 Page 5 CME865R & CME1002R FOR THE INSTALLER: Machine & Bin Assembly Overview: This ice system consists of 4 major assemblies: 1. The ice storage bin. 2. The ice maker itself. 3. The interconnecting refrigerant lines. 4. The remote condenser. Additionally, there will be interconnecting wires between the ice maker and the condenser. The Scotsman remote condenser is powered from the ice maker. The condenser must be located above the ice maker, usually on the roof. On the back of the cabinet is the following notice: REMOTE CONDENSER NOTICE This unit has been designed for use with Underwriter's Laboratories Inc. listed forced air cooled condensers, Scotsman models RCE1001-32A or RCE1002-32A or ERC301. The ice maker, condenser and connecting line sets are factory charged with the correct amount of refrigerant and therefore require no charging in the field unless the system should be opened for service repairs. If other forced air cooled condensers are being considered for use with this ice maker, prior approval from Scotsman is necessary to insure proper system operation. Any alternate forced air cooled condenser being considered must be listed with Underwriters Laboratories, Inc. Certified with C.S.A. and have a minimum design pressure of 500 P .S.I.G. CAUTION A suitable ground path must be provided between the remote condenser cabinet and the ice maker cabinet if the condenser fan is powered from the ice maker. IMPORTANT In order to prevent compressor damage due to refrigerant migration, and to insure acceptable start up, a crankcase heater has been installed on the compressor. This heater is wired to operate at all times. Upon initial start up and any time the unit power supply is interrupted for more than one hour, the machine should not be started for at least 4 hours after the power supply has been reconnected to the machine. Storage Bin: 1. Measure the location of the ice machine floor drain relative to the installed location of the bin. Route all drain lines so that when the machine is installed in its normal position, the drain tubes terminate just above the floor drain. 2. Using corner posts from the bin's carton as a cushion, lay the bin on its back. 3. Install the legs into the leg sockets. 4. Move bin back to an upright position. 5. Remove all material that is packed inside the bin. 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 location which should have a minimum room temperature of 50-degrees F. and maximum room temperature of 100 degrees F. 3. 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. 4. 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. 5. 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. Remote Condenser: A new condenser coil designed for the machine's capacity MUST be used. Because of the possibility of mineral oil contamination, coils and line sets that had been connected to R-12, R-502 or R-22 units MAY NOT BE CONNECTED TO THIS SYSTEM. Doing so voids the refrigeration system warranty. January 1998 Page 6 CME865R & CME1002R 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. 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. Drain Connections: All drains are gravity type and must have a minimum of 1/4 inch per foot fall on horizontal runs. VENT FOR ICE MACHINE DRAIN The drains to be installed must conform with the local plumbing codes. Use only 3/4" rigid tubing. The ice machine's drain must be separate from the bin's drain. Both use 3/4" FPT fittings. Insulation of the bin drain is recommended. Install a vertical open vent on the drain line(s) high point to ensure proper draining. The ideal drain receptacle is a trapped and vented floor drain. CONFORM TO ALL LOCAL CODES. 3/4" FPT DRAIN FITTING 3/8" MALE FLARE WATER INLET WATER TREATMENT DEVICE BIN DRAIN 3/4" FPT OUT THE BOTTOM OF THE BIN SHUT OFF VALVE VENT FOR BIN DRAIN BACK VIEW OF MACHINE ON BIN: INLET WATER AND DRAIN CONNECTIONS FLOOR DRAIN September, 1994 Page 7 CME865R & CME1002R FOR THE INSTALLER: Remote Condenser Locate the condenser as near as possible to the interior location of the ice maker. Location of the condenser is limited by the specific length of pre-charged refrigerant tubing supplied for the application. The pre-charged tubing connects the ice maker to the remote condenser. The condenser must be above the ice maker. Select the best available location, protecting the condenser from extremes of dirt, dust, and sun. Meet all applicable building codes. Roof Attachment: Install and attach the remote condenser unit to the roof of the building, using the methods and practices of construction that conform to the local building codes, including having a roofing contractor secure the condenser to the roof. Pre-charged Line Routing CAUTION Do not connect pre-charged tubing until all routing and forming of the tubing is complete. See the coupling instructions for connecting instructions. 1. Each set of precharged refrigerant lines consists of a 3/8 inch diameter liquid line, and a 1/2 inch diameter discharge line. Both ends of each line ...
