This action fills and rinses the sump during each harvest cycle. Water Distribution System The water distribution system functions to evenly supply water to all cells of the evaporator plates. The water pump pumps water from the sump up the vertical tygon tube to the tee. From there water is channeled through the water manifold to the water distributors, above each evaporator plate, and from six holes within each distributor, water flows to the cells of each side of the evaporator plates. Gravity flow returns the unfrozen excess portion of water to the sump reservoir for recirculation. Hot Gas Solenoid Valve The hot gas solenoid valve opens only during the harvest cycle, to divert the hot discharge gas from the compressor, by passing the condenser and capillary tube, for direct flow to the evaporator plates to release ice cubes from the ice cube molds. SUMP STANDPIPE Fan Pressure Control - Air-Cooled Models only. WATER DISTRIBUTORS ln both freeze and harvest cycles, the fan pressure control functions to maintain a minimum discharge pressure by cycling the fan on and off. Strainer WATER FILTER A water strainer is located in the potable inlet water HAND line before the water inlet solenoid valve. Clean VALVE the water strainer frequently. SUMP PUMP COMPONENT LOCATION September 1993 Page 14 DRAIN CAP CMS1402 CLEANING ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// A Scotsman Ice System represents a sizable investment of time and money in any company's business. In order to receive the best return for that investment, it MUST receive periodic maintenance. Maintenance and Cleaning should be scheduled at a minimum of twice per year. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// CLEANING: ICEMAKER 7. Pour the cleaning solution into the reservoir until full. Move the WASH/OFF/ICE switch to the WASH position. 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 empty the bin of ice. Remove the hose clamp, rubber cap and drain all the water from the sump assembly into a container. 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. [. . . ] Reclaim programs are available thru most refrigerant wholesalers. Use conservation minded service procedures: · If gauges must be used, use very short hoses. Minimal refrigerant discharged into the hoses equals minimal refrigerant discharged into the air. · If hi side pressure must be checked, use a quick connect at the end of the discharge hose to minimize the release of refrigerant, J/B Industires part number A33000 works well. · Scotsman's schrader valve caps must be tightened to 70 inch - pounds to insure that the valves will not leak.
