September 1993 Page 1 WRF560SEYB FOR THE INSTALLER The WRF560SEYBB will fit the following Scotsman ice storage bin (48" wide): BH900, and with adaptors, onto the following Scotsman ice storage bins: Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman that have been altered in any way, including the use of any parts and/or other components not specifically approved by Scotsman. Scotsman reserves the right to make design changes and/or improvements at any time.

Then high pressure, high temperature gas refrigerant being discharged from the compressor is diverted from the condenser through the hot gas solenoid valve into each evaporator plate. The finished ice cubes are released from the sides of each evaporator plate by the warming effect of the hot gas condensing in each evaporator plate and the water cascading over the ice cubes. At the end of the harvest cycle, the timer cam will push in the microswitch actuator arm. If there is no ice close to the bin level control's transducer, a whole new cycle will begin. If there is ice within 8" of the base of the machine (when the bin level control is set for full) the icemaker will shut OFF.

When the suction line gets cold enough, the cube size control closes (on temperature fall) and starts the timer. A change in either ambient air or incoming water temperature will affect the efficiency of the refrigeration system, and this will vary the length of time it takes the evaporator to reach the temperature at which the cube size control is preset to close. Relay The multi-function, three pole, double throw, plug-in relay is inserted into a receptacle on the printed circuit board in the control box. The relay functions in part to by-pass the bin thermostat control to prevent the icemaker from shutting OFF, when the bin thermostat opens during the freezing cycle. The bypass action ensures full-sized ice cubes with each harvest cycle and prevents short cycling on the bin thermostat control. CONTROL BOX Timer - Timer & Switch Assembly The timer cam is controlled by the cube size control. Mix 24 ounces of Scotsman Ice Machine Cleaner with 2 gallons of warm (950F. During the wash cycle, if the machine runs out of solution, mix 2 more gallons of solution per step 6, refill the sump and continue the wash cycle for the remainder of the 30 minutes. Remove the reservoir drain cap and drain the cleaning solution from the sump. Rotate the shaft of the timer and switch assembly CLOCKWISE to the harvest position (low part of the cam against microswitch). Move the WASH/OFF/ICE switch to the ICE position to start the Harvest cycle. If, after completing this procedure, one or more evaporator plates does not have a full flow of water for each vertical column of cubes, shut down the operation and remove and clean all water distributor manifolds. Reinstall the water distributor manifolds. Note: Thie ice making portion of the water system should be sanitized after cleaning by repeating steps 2-12, except substitute an approved sanitizing solution for the cleaning solution. 13. Move the compressor ON-OFF switch to the ON position to start the icemaking process. ////////////////////////////////CAUTION////////////////////////////////// DO NOT use ice produced from the cleaning solution. /////////////////////////////////////////////////////////////////////////////////// 14. Check the next ice cube harvest to be sure that the ice cubes are clear and the acid taste is gone. [. . . ] Reverse to reassemble, refer to wiring diagram as needed. STRAINER September 1993 Page 24 WRF560SEYB REFRIGERATION SERVICE General: · Scotsman recommends that any work on the refrigeration system only be done when it is certain that the system needs repair. · Refrigerant should not be added except as a way to determine the proper operation of the product. If the system was low on refrigerant, there is a leak, and it must be found and repaired. · Although this system uses R-22, it should not be wasted to the atmosphere, but reclaimed. [. . . ]
