FOR THE ELECTRICIAN . [. . . ] 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. See Removal and Replacement to replace bearing or seals. 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 March 1997 Page 15 Double System RL 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. "Soft" water may not be the complete answer. Check with a water treatment specialist regarding water treatment. DIVIDER, AUGER AND SLOTTED COLLAR ALLEN HEAD SCREWS Switch off electrical power, and shut off the water supply. For more information on removal of these parts, see REMOVAL AND REPLACEMENT. To remove the auger, remove front and top panel. 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. Push bail clamp back and remove ice chute cover. Loosen band clamp under ice chute, and remove ice chute from evaporator. Remove 4 allen head screws holding breaker to evaporator. Allow the auger to dry, the stainless steel of the auger and evaporator must be clean and bright. Clean the auger and evaporator as required. Reverse to reassemble. March 1997 Page 16 Double System RL SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: Voltage to the unit, restore it if there is none. Check: The master switch, switch ON if off. The machine will not run if there is not enough water in the reservoir. [. . . ] 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. [. . . ]
