User manual SCOTSMAN FM2400RH

[. . . ] FM2400RH 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 FM2400RH (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-502 system. It consists of two evaporators, two gearmotors, two liquid line valves, two control boxes, two thermostatic expansion valves, and an EPR valve. For the Installer . [. . . ] Check and tighten all bolts and screws. CLEAN THE WATER LEVEL SENSOR ///////////////////////////// CAUTION: THE TIMP IS MADE OF GLASS /////////////////////////////// SPANNER WRENCH (only needed on units mfg. before 1991) ICE SWEEP reservoir, and the tip wiped clean of mineral buildup. The bearing in the breaker should also be checked at least two times per year. Check the bearing by: · removing the ice chute cover · unscrewing the ice sweep · removing the water shed · using a spanner wrench and unscrewing the breaker cover · unscrewing the auger stud Inspect the assembly, looking for wear. Reverse to reassemble. August 1994 Page 15 FM2400RH CLEANING In some installations the water supply to the icemaker 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. Check with a water treatment specialist regarding water treatment. DIVIDER, AUGER AND SLOTED COLLAR ALLEN HEAD SCREWS Switch off electrical power, and shut off the water suplly. 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. 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. Allow the auger to dry, the stainless steel of the auger and evaporator must be clean and bright. Reverse to reassemble. August 1994 Page 16 FM2400RH SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: The reset switch, (on the circuit board): depress and release the switch. It opens from excess pressure of ice inside the ice chute: this should only happen when the machine does not shut off when the ice storage bin is full. This switch will reset when the ice melts, but the machine will not resart until the reset switch on the circuit board is pressed. E. The machine will not run if there is not enough water in the reservoir. See the next step. August 1994 Page 17 FM2400RH SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES F. Check: The gear motor, if it will not run, the liquid line valve will not open. If no power to it: Check: The indicator lights on the circuit board, the bin empty light should be ON, the no water light should be OFF . If the line side has the correct voltage and the load side does not, replace the transformer. [. . . ] GEARCASE 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. [. . . ]
