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. They meet or exceed the standards of U. L. , N. S. F. , and C. S. A. [. . . ] When the microswitch button is pushed in there is power connected to the coil of the relay, and the unit is in the freeze cycle. When the microswitch button is released, the power to the relay is stopped, and the unit goes into harvest. The microswitch is actuated by a cam assembly directly connected to the timer motor. One complete rotation of the cam will take eight minutes. Harvest is preset at three and one half minutes, but is adjustable. High Pressure Safety Control This is a manual reset control that shuts down the icemaker, should the discharge pressure ever reach 450 PSIG (air cooled) or 350 PSIG (water cooled). Found below the control box. CUBE SIZE CONTROL RELAY TIMER AND MICROSWITCH ICE/OFF/WASH SWITCH BIN ICE LEVEL SELECTOR SWITCH September 1993 Page 12 WRF560SEYB COMPONENT DESCRIPTION Bin Level Control This electronic control uses sound waves to measure the distance between the bottom of the ice machine and the top of the ice in the bin. It is designed to control the machine's ice production to maintain that distance. The control is adjustable so that the ice machine will maintain a certain height of ice. When set at FULL it will not allow the machine to fill the bin any closer to the ice machine than about 8", and it will not work if the distance to the bottom of the bin is greater than 8 feet. BIN ICE LEVEL SELECTOR SWITCH ICE/OFF/WASH SWITCH Because it uses sound waves, a slight "ticking" sound can be heard coming from the bottom of the machine. There are two parts to the control, the circuit board, and the level control switch. THE USER CAN SELECT THE AMOUNT OF ICE TO BE MAINTAINED IN THE BIN. SOUND WAVES FULL PARTIAL September 1993 Page 13 WRF560SEYB COMPONENT DESCRIPTION Water Inlet Solenoid Valve The water inlet solenoid valve fills the sump assembly with water. Move the WASH/OFF/ICE switch to the OFF position. 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. Add hot water to the bin to melt the ice. [. . . ] · When brazing the tubing connections to the hot gas valve or thermostatic expansion valve, the component must be protected by heat sink material. Specifically: Recover, reclaim or recycle refrigerant. The method chosen is up to the service company. There are various mechanical devices that may be used to recycle refrigerant at the field level, however, Scotsman requires that any refrigerant placed into a Scotsman ice machine meet ARI spec 700.
