[. . . ] 25 Removal and Replacement Water Reservoir & Bin Controls . 36 Parts Lists and Wiring Diagrams are located in the center of this manual, printed on yellow paper. This Manual Was Printed On Recycled Paper November 1992 Page 1 WRF535SWBM FOR THE INSTALLER The WRF535SWBM is designed to fit the following Scotsman storage bins: · B90 and extensions, with bin top KBT18. · BH800 using bin top KBT15 (one unit). · BH800 if using two units, no bin top needed. [. . . ] Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin. Sanitize the bin interior with an approved sanitizer using the directions for that sanitizer. Replace the panels.

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. SLIDE UP TO REMOVE ICE CHUTE ICE LEVEL SENSORS SLIDE LEFT TO REMOVE RESERVOIR WATER LEVEL SENSOR Inspect the assembly, looking for wear 4. Use a vacuum cleaner or coil cleaner if needed. Check and tighten all bolts and screws. ////////////////////////////////////// CAUTION: THE TIP IS MADE OF GLASS /////////////////////////////////////// ICE SWEEP 3. The top bearing in the breaker should also be checked at least two times per year. Check that the fan blades are clean, and the fan secure to the fan motor shaft. Check the head pressure control valve, it should be maintaining a head pressure above 220 psig. If the unit has the correct charge, and the condenser is clean, and the refrigerant lines are not kinked or twisted, and the condenser is not overheated by external heat loads, the head pressure should be under the trip out point of the head pressure control switch. If all of the above are found to be good, and the machine trips out on high head pressure, replace the head pressure control valve. E. This switch will open if the bin control (ice level sensor) does not shut the machine off when the ice storage bin is full of ice: ice backs up in the ice chute, and internal pressure opens the switch, stopping the machine. If, after resetting the switch, the machine does start, check: a. The ice level sensors, they may need cleaning (see maintenance). If there is not enough water in the reservoir, the water level sensor will keep the machine from starting. a. Check the water level, restore/adjust if low. Check the water level sensor, clean if dirty, (see maintenance). If the machine does not start, see the next page. November 1992 Page 25 WRF535SWBM SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES G. [. . . ] 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. E) After the case is together, and the locating pins are secure in both ends, replace all cap screws. [. . . ]
