[. . . ] FM2400R 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. It features: front service for the freezer, gearmotor, control box, water reservoir, and bin control; an electronic circuit for monitoring ice and water level; a thermostatic expansion valve; and R-502 as the refrigerant. TABLE OF CONTENTS For the Installer Specifications . 37 Parts Lists and Wiring Diagrams are located in the center of this manual, printed on yellow paper. December, 1988 Page 1 FM2400R FOR THE INSTALLER The FM2400R is designed to fit the following Scotsman storage bins: · B590 and extentions, with bin top KBT18. When installing a new system, check to be sure that you have everything you need before beginning: · Correct Bin · Correct Ice Machine · Correct Bin Top · All kits, legs, and information required for the specific job. There are two separate ice making and refrigeration systems in this model. [. . . ] ////////////////////////////////////////////////////////////////////////// 15. Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin. Sanitize the bin interior with an approved sanitizer using the directions for that sanitizer. Replace the front panel. December, 1988 Page 21 FM2400R MAINTENANCE AND CLEANING The FM2400R is made up of two separate ice makers; to properly clean and maintain the FM2400R, these steps must be followed for both systems. ICE CHUTE /////////////////////////////WARNING/////////////////////////// Disconnect electrical power before beginning. ////////////////////////////////////////////////////////////////////////// ICE LEVEL 1. The bin control uses devices that sense SENSORS SLIDE LEFT TO light, therefore they must be kept clean REMOVE 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 SLIDE UP TO REMOVE RESERVOIR WATER LEVEL SENSOR ////////////////////////////////////// CAUTION: THE TIP IS MADE OF GLASS /////////////////////////////////////// Inspect the assembly, looking for wear 4. Check and tighten all bolts and screws. ICE SWEEP 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 buildup. 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 · using a spanner wrench and unscrewing the breaker cover (left hand thread) · unscrewing the auger stud SPANNER WRENCH BREAKER COVER December, 1988 Page 22 FM2400R MAINTENANCE AND CLEANING In some areas the water supply to the icemaker will have a great deal of minerals in it, and that will result in ann 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. Check with a water treatment specialist regarding water treatment For more information on removal and replacement of these parts, see REMOVAL AND REPLACEMENT. Remove 3 hex studs 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.

"Soft" water December, 1988 Page 23 FM2400R SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: The 2 reset switches (circuit board and high pressure): depress and release each switch. If the unit still does not start, check the spout switch, 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. [. . . ]
