Water Distribution System The water distribution system evenly supplies 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 functions only during the harvest cycle, to divert the hot discharge gas from the compressor, by passing the condenser, for direct flow in the evaporator plates to release ice cubes from the ice cube molds. The hot gas solenoid valve is installed in a branch of the discharge line. When the harvest cycle begins the energized solenoid coil lifts the valve stem within the valve body, to cause the hot discharge gas to be diverted to the evaporators. Strainer A water strainer is located in the potable inlet water line before the water inlet solenoid valve. Clean the water strainer frequently. WATER DISTRIBUTORS SUMP STAND PIPE OPTIONAL WATER FILTER HAND VALVE SUMP PUMP COMPONENT LOCATION April, 1993 Page 17 DRAIN CAP MCM1462R 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. ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// 7. Pour the cleaning solution into the reservoir until CLEANING: ICEMAKER full. Move the master switch to the WASH position. 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. Move the ICE-OFF-WASH switch to the OFF (center) position. Remove the 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 ICE-OFF-WASH 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. Electrical Shock Hazard. [. . . ] · 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. · If using recycled refrigerant, it must meet ARI spec 700 or have been cleaned by a machine capable of attaining ARI spec 700. If the refrigeration system must be serviced, the quality of service must insure that there will not be a repeat failure, as repeat failures will cause refrigerant to be discharged into the air by the failure or when the failure is corrected: · If there has been a compressor burn out, check for acid in the oil.
