NME1254 & FME1504 FOR THE INSTALLER These machines are designed to fit the following Scotsman storage bins: · SB480 and extensions (with bin top KBT18) · HTB555 or BH550 - direct fit · BH800 using bin top KBT23 · BH801 using bin top KBT29 · BH900 using bin top KBT22 NME1254 Dispenser Applications The NME1254 can be placed on and used with certain ice and ice-beverage dispensers. ·ID200 or ID250, use adapter KBT44 and KNUGDIV and KDIL-N-ID2 ·Cornelius ED/DF200 beverage KBT44 and KDIL-N-250 dispensers, use KBT44 and KDIL-N-200 ·Cornelius ED/DF250 beverage dispensers, use ·Lancer special-for-nugget Ice Beverage Dispenser, use KDIL-N-L & Lancer kit #82-3491 ICE MACHINE SPECIFICATIONS Model Number Cabinet Dimensions W" x D" x H" 30 x 24 x 27 30 x 24 x 27 30 x 24 x 27 30 x 24 x 27 Basic Electrical 208-230/60/1 208-230/60/1 208-230/60/1 208-230/60/1 Condenser Type Ice Type Refrigerant Charge (R-404A) Air Cooled Flake 36 ounces Water Cooled Flake 24 ounces Air Cooled Nugget 36 ounces Water Cooled Nugget 24 ounces January 2005 Page 2 Minimum Circuit Ampacity 15. 0 14. 3 15. 0 14. 3 Maximum Fuse Size 20 20 20 20 FME1504AS-32B FME1504WS-32B NME1254AS-32B NME1254WS-32B Minimum circuit ampacity is used to determine wire size per National Electric Code. FOR THE INSTALLER: Environmental Limitations Installation Limitations: This ice system is designed to be installed indoors, in a controlled environment: Min. Air Temperature 500F 1000F Water Temperature 400F 1000F Water Pressure 20 psi 80 psi Voltage 198 253 (Compared to the nameplate) Operating the machine outside of the limitations is misuse and can void the warranty. NME1254 & FME1504 Water Limitations An ice machine makes food. [. . . ] After draining the reservoir, as in step 6, wash and rinse the water reservoir. January 2000 Page 15 NME1254 & FME1504 SENSOR and CONDENSER MAINTENANCE 1. The bin control is a device that senses light, and must be kept clean enough so that they can "see". At least twice a year, remove the bin control sensors from the base of the ice chute, and wipe the inside clean, as illustrated. The ice machine senses water level by a probe located in the water reservoir. At least twice a year, the probe should be removed from the reservoir, and the tip wiped clean of mineral build-up. ICE CHUTE SLIDE IN AND OUT ICE LEVEL SENSORS Clean the Probe's Tip with ice machine cleaner and a clean, soft cloth. 3. Clean or replace the air cooled condenser filter. Clean the air cooled condenser. Do NOT use a wire brush. June 2002 Page 16 BEARING MAINTENANCE The bearing in the breaker should also be checked at least two times per year. Check the bearing by: ·removing the ice chute cover Chute Cover NME1254 & FME1504 ·unscrewing the auger stud Auger Stud Cap Screw ·unscrewing the ice sweep Ice Sweep Inspect the bearing. If grease is needed the bearing and breaker should be removed to check the action of the bearing. To remove the breaker remove the lower ice chute then take out all four allen head cap screws and pull the breaker off the auger and evaporator. If the bearing only needs grease, inject grease into the bearing using Scotsman grease needle pn 02-3559-01 and Scotsman bearing grease cartridge, pn A36808-001. See Removal and Replacement section to replace bearing or seals. Needle, pn 02-3559-01 ·removing the water shed & unscrewing the breaker cover (left hand threads). Breaker Cover Off Reverse to reassemble. January 2000 Page 17 AUGER MAINTENANCE NME1254 & FME1504 Hazardous Moving Parts. Disconnect electrical power before beginning maintenance. ALLEN HEAD SCREWS In some areas, the water supply to the Ice Machine will contain a high concentration of minerals, and that will result in an evaporator and auger becoming coated with mineral scale, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, remove the auger so the parts can be inspected. Note: Water filters can filter out suspended solids, but not dissolved solids. For more information on removal of these parts, see REMOVAL AND REPLACEMENT. Push back bail clamp holding ice chute cover to ice chute, and remove cover. Drain the evaporator by lowering and uncapping the evaporator drain hose. After the auger has been removed, allow the auger to dry: if the auger is not bright and shiny, it must be cleaned. Reverse to reassemble. BREAKER & BEARING & AUGER ASSEMBLY Handle auger with care, it has sharp edges. June 2002 Page 18 SERVICE DIAGNOSIS: Symptom No ice is made, nothing operates Possible Cause Unit off due to no power NME1254 & FME1504 Probable Correction Restore Power Switch master switch to ON. Check for water interruption (water cooled) or fan motor failure (air cooled). Circuit board has shut ice machine down due to high auger motor amp draw. [. . . ] Note: The case cover output gear, bearings, and shaft are one pressed together assembly. If the oil level and condition is acceptable, quickly check the gears and bearings. If there is evidence of water in the oil (rusty bearings and gears; the oil having a creamy white appearance; oil level too high) carefully inspect the bearings and gears. Note: The gears and bearings are available only as pressed together sets. [. . . ]
