January 2005 Page 2 SAMPLE BIN AND MACHINE COMBINATIONS NME654 & FME804 FME804 ON BH550* NME654 ON BH800* The Nameplate is located on the back of the machine. A Serial Number Plate is located inside the cabinet, behind the front panel. FME804 ON BH900* *Bin Top Kit Required January 2000 Page 3 NME654 & FME804 FOR THE INSTALLER Location: Install the machine be installed in a location where it has enough space around it to be accessible for service. A minimum of 6" must be allowed at the back for air circulation on air cooled models. Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the environmental limitations. Water Limitations: An ice machine is a food manufacturing plant: it takes a raw material, water, and transforms it into a food product, ice. The purity of the water is very important in obtaining pure ice and in maximizing product life. This section is not intended as a complete resource for water related questions, but it does offer these general recommendations: 1. Check with a water treatment specialist for a water test, and recommendations regarding filters and treatment. 2. In most cases, the water used to make ice should be filtered or treated, depending upon the water. There is no one type of water filter that is effective in all situations. That is why a water test is important. RO Water Limitation: Water conductivity must be no less than 35 microSiemens/cm. Note: 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 CUL. 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. Storage Bin: Tip the storage bin on its back, using parts of the carton to protect the exterior finish. Install the legs into the threaded holes in the bottom of the bin. Turn the leg levelers all the way in preparation for leveling later. Return the bin to the upright position, remove paper covering the bin gasket. Note: Do not push bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the legs and the leg mounts. Install the appropriate bin top on the bin, according to the instructions for the bin top. Ice Machine: The machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough to install on top of the bin. After the unit is placed on the bin, line it up so it is even with the back side. Secure the machine to the bin with the hardware provided with the machine. Remove the front panel and remove any shipping blocks. Note: When placing 2 of these machines on a BH800 without the bin top, removal of the 2 service panels facing each other will make future service easier: 1. Remove the 2 top panel screws that will face each other. 2. Remove the 2 service panels that will face each other. 3. Add a strip of gasket, such as Scotsman part number 19-0503-04, to the 2 base edges that will face each other and around service panel space on the 2 panels that will face each other. When the 2 machines are placed on the bin, the gaskets will seal the bin top area and the space between the machines. May 2001 Page 4 FOR THE INSTALLER: Location NME654 & FME804 DO NOT STACK ANYTHING IN FRONT OF THE MACHINE(S) TWO UNITS ON ONE BIN ALLOW ROOM FOR AIR CIRCULATION AND SERVICE ACCESS January 2000 Page 5 NME654 & FME804 FOR THE PLUMBER Water Inlet Air Cooled Models: Use 3 8" O.D. copper tubing to connect cold potable water to the 3 8" male flare fitting at the back of the cabinet. Install a hand valve near the machine to control the water supply. Water Treatment: In most areas, a water filter of some type will be useful. In areas where the water is highly concentrated with minerals the water should be tested by a water treatment specialist, and the recommendations of the specialist regarding filtration and/or treatment should be followed. Water Cooled Models: Connect a separate 3 8" O.D. copper line, with a separate hand valve, to the 3 8" FPT condenser inlet at the back of the cabinet. The water pressure to all lines must always be above 20 PSIG, and below 80 PSIG. CONFORM TO ALL APPLICABLE CODES Drains Air Cooled Models: Connect a drain tube to the ¾" FPT drain at the back of the cabinet, the drain line is of the gravity type, and ¼ inch per foot fall is an acceptable pitch for the drain tubing. There should be a vent at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented floor drain. Use only ¾" rigid tubing. Water Cooled Models: In addition to the above mentioned drain, a separate condenser drain must be installed. Connect it to the ½" condenser drain connection at the back of the cabinet. Storage Bin: Install a separate gravity type drain, similar to the air cooled drain. Insulation of this drain line is recommended.

Check the nameplate (located on the back panel) for the voltage requirements, and for the minimum circuit ampacity. The machine requires a solid chassis to earth ground wire. NME654 & FME804 The ice machine should be connected to its own electrical circuit so it would be individually fused. Voltage variation must remain within design limitations, even under starting conditions. All external wiring must conform to national, state, and local electrical codes. The use of a licensed electrician is required to perform the electrical installation. CONFORM TO AL ...
