October 1993 Page 1 MCM1062R SPECIFICATIONS Always refer to the nameplate, located on the back of the cabinet, for the: · model number, · serial number, · basic electrical requirements, · minimum circuit ampacity, · maximum fuse size, · and refrigerant charge. A serial number plate with the model number, serial number and refrigerant charge is located behind the front panel, near the control box. The unit comes from the factory with the correct refrigerant charge contained in the receiver. The refrigerant charge information is for recharging, should that be necessary. All utility connections and refrigerant line connections are made at the back of the ice maker. 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. Installer: After installation, take this manual with you, do NOT leave it with the machine. October 1993 Page 2 MCM1062R FOR THE INSTALLER: Environmental Limitations Installation Limitations The ice making portion of this ice system is designed to be installed indoors, in a controlled environment. 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. NAMEPLATE, LOCATED ON BACK PANEL. A SERIAL NUMBER PLATE IS LOCATED BEHIND THE FRONT PANEL, NEAR THE CONTROL BOX. October 1993 Page 3 MCM1062R FOR THE INSTALLER: Machine & Bin Assembly Overview: This ice system is comprised 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. 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 casters into the leg sockets. 4. Move bin back to an upright position. 5. Check that the back set of casters are in in line to allow the bin to be rolled back and forth. 7. Hang the scoop holder and scoop from the front edge of the bin (inside the bin). 8. Install the bin bumpers at the back of the bin. 9. 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. Attach the bin bumpers to the bin with the bolt holding the mounting strap to the bin. When alignment and leveling are completed, tighten the bolts to secure the mounting straps. MOUNTING STRAPS AND BOLTS BIN BUMPER 5" October 1993 Page 4 MEASURE THIS DISTANCE FLOOR DRAIN MCM1062R 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. ln some cases a plumber will be required. Drain Connections: Drain tubing and fittings are supplied with the ice bin. All drains are gravity type and must have a minimum of 1/4-inch fall per foot on horizontal runs. The drains to be installed must conform with the local plumbing code. Install a vertical open vent on the drain line(s) high point to ensure good draining. The ideal drain receptacle is a trapped and vented floor drain. October 1993 Page 5 MCM1062R FOR THE INSTALLER: Remote Condenser Scotsman 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 icemaker 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.

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 have quick connect couplings, one end has flexible tubing: that end goes to the icemaker. Note: The openings in the building ceiling or wall, listed in the next step, are the minimum sizes recommended for passing the refrigerant lines through. 2. Have the roofing contractor cut a minimum hole for the refrigerant lines of 1.75". Check local codes, a separate hole may be required for the electrical power to the condenser. /////////////////////////////CAUTION//////////////////////////////// DO NOT KINK OR CRIMP REFRIGERANT TUBING WHEN INSTALLING IT. //////////////////////////////////////////////////////////////////////////// 3. Route the refrigerant lines through the roof opening. Follow straight line routing whenever possible. Any excess tubing MUST be retained within the building. 4. Spiral any excess length of pre charged tubing inside the building. Use a horizontal spiral (as illustrated) to avoid any traps in the lines. 5. Have the roofing contractor seal the holes in the roof per local codes. 6. The flexible line end must be installed behind the icemaker, it is to be looped down from the ice machine connection area then back up to the wall behind the ice machine. This allows the ice machine to be pulled out for service.
