User manual SCOTSMAN FME2400RH

[. . . ] FME2400RH 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 FME2400RH (remote high side) is the freezer portion of a commercial ice machine. It is designed to be connected to the condensing section of a refrigeration system, specifically a supermarket R-404A system.

FOR THE ELECTRICIAN . [. . . ] 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. Slowly pour the cleaning solution into the water reservoir until it is full. As the ice maker begins to use water from the reservoir, continue to add more cleaning solution to maintain a full reservoir. After all of the cleaning solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch to OFF. After draining the reservoir, as in step 6, wash and rinse the water reservoir. January 1996 Page 14 FME2400RH MAINTENANCE SLIDE ICE LEVEL CONTROLS OUT OF CHUTE Electrical Shock Hazard Electrical shock can cause personal injury. 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. CLEAN THE ICE LEVEL CONTROL SENSORS Inspect the assembly, looking for wear. Check and tighten all bolts and screws. RESERVOIR ICE SWEEP CLEAN THE WATER LEVEL SENSOR ///////////////////////////// CAUTION: THE TIMP IS MADE OF GLASS /////////////////////////////// BREAKER COVER 3. The bearing in the breaker should also be checked at least two times per year. Check the bearing by: ·pushing the bail clamp back and removing the ice chute cover ·unscrewing the ice sweep ·unscrewing the breaker cover ·unscrewing the auger stud January 1995 Page 15 FME2400RH CLEANING In some installations the water supply to the ice maker will be so concentrated with dissolved minerals, (such as calcium carbonate) that as ice is made, the evaporator and auger become coated with the minerals, requiring a more frequent cleaning 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. For more information on removal of these parts, see REMOVAL AND REPLACEMENT. If top panel cannot be removed, or if there is less than 6" clearance over the top of the machine, the gearmotor/evaporator may be slid out for service access. Loosen band clamp under ice chute, and remove ice chute from evaporator. Allow the auger to dry, the stainless steel of the auger and evaporator must be clean and bright. Reverse to reassemble. DIVIDER, AUGER AND SLOTTED COLLAR ALLEN HEAD SCREWS January 1995 Page 16 FME2400RH SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. The machine will not run if there is not enough water in the reservoir. Check: The gear motor, if it will not run, the liquid line valve will not open. [. . . ] Lower the auger into the evaporator barrel, slightly turning it to match up with the drive end. Complete the reassembly by reversing the disassembly for the breaker & thrust bearing assembly.
