August 1994 Page 1 WRF540CWBB FOR THE INSTALLER: Specifications The WRF540CWBB is designed to fit the Scotsman storage bins BH800 or B90. Leg kit KLP4 is recommended when using both the B90 bin and an extension. Installation Limitations: The WRF540CWBB is BACK VIEW 15. 53" 3. 1" and performance. [. . . ] Continue ice making for at least 15 minutes, to flush out any cleaning solution. ///////////////////////////////WARNING///////////////////////// DO NOT USE any ice produced from the cleaning solution. ////////////////////////////////////////////////////////////////////////// 15. 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. 18. Replace the front panel. August 1994 Page 14 WRF540CWBB MAINTENANCE ////////////////////////////WARNING//////////////////////////// Disconnect electrical power before beginning. ///////////////////////////////////////////////////////////////////////// 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. 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 SLIDE ICE LEVEL CONTROLS OUT OF CHUTE RESERVOIR CLEAN THE ICE LEVEL CONTROL SENSORS 4. If the transformer is good, and the bin empty light is OFF, check the ice level sensors. Look through the ice chute "eye" hole for something blocking the ice chute. Unplug "opto trans" and "LED" connectors from the circuit board. Plug "opto trans" and "LED" connectors from the Scotsman Electronic Control Testor Model NM1 into the circiut board. a. Move the "bin full" switch on the tester to the full position. The bin full light on the tester should be ON, if not, replace the circuit board. If the bin full light on the tester is ON, move the tester switch to "bin empty" the light on the tester should go OFF and the bin empty light on the circuit board should go ON. If it does as above, and the machine still does not run, replace the ice level sensors. If the transformer is fine, and the "no water" light is ON, check the water level sensor. Remove the water level sensor from the reservoir and clean the tip if dirty. If the no water light is still on, check that the "water sen" plug is firmly plugged into the circuit board.

Unscrew the 4 cap screws holding the gearmotor to the gearmotor plate. A) Remove the cap screws holding the gearmotor case halves together and pry the two cases apart. 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.
