They meet or exceed the standards of U. L. , N. S. F. , and C. U. L. [. . . ] Remove the block from the float in the water reservoir. Continue ice making for at least 15 minutes, to flush out any cleaning solution. DO NOT USE any ice produced from the cleaning solution. 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. Wait 15 minutes, then switch the master switch to ON. 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. November 2000 Page 14 SENSOR MAINTENANCE 1. 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. SLIDE ICE LEVEL CONTROLS OUT OF CHUTE Double System RL 2. Check/clean ice level sensors No ice, auger motor is turning Unit makes ice, but very slowly Clean water level sensor Auger can't turn. Circuit board has not yet shut unit down. Auger turning but there is no refrigeration Liquid line valve not opening, effect check coil, check board relay. No refrigerant to ice machine, check main system. Unit is shut down Circuit board has shut ice machine down due to high auger motor amp draw. Check for cause of high amp draw, including bearings, gear motor condition and scale on auger & evaporator. May also be due to liquid line valve leak thru during the off cycle. Auger not turning Due to: motor failure; auger relay failure on circuit board; or gears stripped. Low suction pressure Liquid line valve not opening due to coil failure or failure of compressor relay on circuit board EPR setting too low, check/adjust TXV restricted or not metering. No power to circuit board Check harness Circuit board gear motor relay will not close Check / replace board Water level or ice level sensor failed Check / replace sensor Liquid line valve coil is open Check / replace valve coil Circuit board relay will not close Check / replace board High discharge pressure because of dirty Clean condenser. condenser Auger and evaporator are coated with Clean the water system minerals Low suction pressure due to low EPR Adjust EPR, check TXV setting superheat November 2000 Page 18 SERVICE DIAGNOSIS Symptom Water Leak Possible Cause Drain plugged up Tubing cracked Condensation on drain tubing Hose off Reservoir cover off Reservoir cracked Evaporator water seal leaks Double System RL Probable Correction Clean out drain Replace tubing Insulate tubing Reattach hose Return cover to reservoir Replace reservoir Check base of evaporator & drip pan. [. . . ] After the gearmotor has been inspected, fasten the evaporator to the gear motor, torque the bolts to 110 inch pounds. 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. Heat sink the TXV body when unsweating or resweating the adjacent tubing. b) At the suction line at the joint about 3" from the evaporator. [. . . ]
