User manual SCOTSMAN NME950R

[. . . ] NME950R & FME1200R INTRODUCTION To the owner or user: The service manual you are reading is intended to provide you, and the maintenance or service technician, with the information needed to install, start up, clean, maintain, and service this ice system. The ice machines covered in this manual are a remote condenser type modular ice system that fits a variety of Scotsman storage bins. They feature: front service for the freezer, gear motor, control box, water reservoir, and bin control; an electronic circuit for monitoring ice and water level; a thermostatic expansion valve; and R-404A as the refrigerant.

[. . . ] Drain the reservoir and thoroughly wash the interior of the reservoir and cover with sanitizer solution. Continue ice making for at least 15 minutes, to flush out any cleaning solution. DO NOT USE any ice produced from the cleaning solution. Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin. Sanitize the bin interior by washing the interior of the bin with the balance of the sanitizer solution. Switch the master switch ON. January 1996 Page 21 NME950R & FME1200R MAINTENANCE AND CLEANING ICE CHUTE Moving Parts Hazard. Disconnect electrical power before beginning. ICE LEVEL SENSORS SLIDE LEFT TO REMOVE 1. The bin control uses devices that sense light, therefore they 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. SLIDE UP TO REMOVE RESERVOIR Inspect the assembly, looking for wear 4. Check and tighten all bolts and screws. ICE SWEEP WATER LEVEL SENSOR ////////////////////////////////////// CAUTION: THE TIP IS MADE OF GLASS /////////////////////////////////////// BREAKER COVER 3. The top bearing in the breaker should also be checked at least two times per year. Check the breaker bearing by: · removing the ice chute cover · unscrewing the ice sweep · removing the water shed · unscrewing the breaker cover (left hand thread) · unscrewing the auger stud December 1995 Page 22 NME950R & FME1200R MAINTENANCE AND CLEANING In some areas the water supply to the ice maker will have a great deal of minerals in it, and that will result in an evaporator and auger becoming coated with these minerals, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, the auger can be removed so the parts can be inspected. Note: Water filters can filter out suspended solids, but not dissolved solids. Check with a water treatment specialist regarding water treatment For more information on removal and replacement of these parts, see REMOVAL AND REPLACEMENT. 1. Push back bail clamp holding ice chute cover to ice chute, and remove cover. Loosen band clamp under ice chute, and remove ice chute from evaporator. 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. ALLEN SCREWS BREAKER & BEARING & AUGER ASSEMBLY December 1995 Page 23 NME950R & FME1200R SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: The reset switch (high pressure): depress and release the switch. If the unit still does not start, check the spout for too much ice, or high side pressure. [. . . ] Note: The gears and bearings are available only as pressed together sets. D) After replacing parts as required, (if any) reassemble the gearcase. The two smaller gears and the oil should be in the lower case, the output gear will be with the cover. As you lower the cover onto the lower case, cover will have to be moved closer to the second gear after the output gear has cleared the second gear top bearing. [. . . ]
