[. . . ] Single System RL 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. This Remote Low side unit 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 . [. . . ] 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 1997 Page 13 Single System RL 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 1997 Page 14 Single 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. 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 1997 Page 15 Single System RL 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. 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. [. . . ] B) To lift off the cover, lift up until you can feel internal contact, then pull the cover towards the output gear end, and then lift the cover (with drive motor attached) up and away from the gear motor case. 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. [. . . ]
