April, 1993 Page 1 WRX988SIBB FOR THE INSTALLER The WRX988SIBB will fit Scotsman ice storage bin MDB900 and is stackable with stacking kit KSMCM48. Either a Scotsman remote condenser or a Mac 6 condensing system are required to for this ice system. [. . . ] 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 400 PSIG. Low Pressure Control (Pump Down) This pressure control connects power to the compressor contactor coil. Its Cut In is 35 PSIG and its Cut Out is 20 PSIG. Located below the control box. CONTROL BOX CUBE SIZE CONTROL RELAY TIMER & SWITCH BIN ICE LEVEL SELECTOR SWITCH April, 1993 Page 15 WRX988SIBB 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. Because it uses sound waves, a slight "ticking" sound can be heard coming from the bottom of the machine. Reinstall the water distributor manifolds. Electrical Shock Hazard. Electrical shock can cause personal injury. Cleaning procedures are done with the power ON. Remove the control box cover, and rotate the shaft of the timer and switch assembly CLOCKWISE advancing to the freezing cycle. (Beginning of the higher part of the cam against the microswitch). Open the ice storage bin door and discard all the ice. Remove the hose clamp, rubber cap and drain all the water from the sump assembly into the bin. Mix 24 ounces of Scotsman Ice Machine Cleaner with 2 gallons of warm (950F. Scotsman Ice Machine Cleaner contains acids. In case of external contact, flush with water. KEEP OUT OF THE REACH OF CHILDREN. Note: The ice making portion of the water system should be sanitized after cleaning by repeating steps 2-12 and substituting a sanitizing solution for the cleaning solution. 13. [. . . ] 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. Reclaim programs are available thru most refrigerant wholesalers. Use conservation minded service procedures: equals minimal refrigerant discharged into the air. [. . . ]
