[. . . ] High Temperature Cut Out This temperature sensor is located next to the hot gas valve, on the outlet side. During normal operation, it does not affect the ice machine, but it will shut the machine off if the hot gas line overheats. It is an automatic reset. September, 1993 Page 11 CMS1002W COMPONENT DESCRIPTION Ice 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. It will not fill any closer to the ice machine than 8", and 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. ON/OFF/WASH SWITCH ICE LEVEL SELECTOR SWITCH THE AMOUNT OF ICE MAINTAINED IN THE BIN CAN BE SELECTED BY THE USER FULL PARTIAL September, 1993 Page 12 CMS1002W COMPONENT DESCRIPTION Electric Water Inlet Valve The water inlet solenoid valve fills the reservoir assembly with water. Excess water overflows out the overflow standpipe located at the back of the reservoir. This action fills and rinses the reservoir during each harvest cycle. Water Distribution System The water distribution system evenly supplies water to all cells of the evaporator plates. The water pump pumps water from the reservoir 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 reservoir for recirculation. Reservoir The reservoir, located below the evaporators, stores the inlet water charge, and collects the water that flows over the evaporator plates. Above the reservoir, but below the evaporators are the cube chutes, designed to retain any water splash from ice making or harvest. Most ice will be falling into the bin below the center evaporator. Strainer A water strainer is located in the potable inlet water line before the water inlet solenoid valve. High Pressure Safety Control This is a manual reset control that shuts down the icemaker, should the discharge pressure ever reach 350 PSIG. WATER DISTRIBUTION SYSTEM EVAPORATOR WATER REGULATING VALVE WATER PUMP RESERVOIR HIGH PRESSURE CUT OUT STRAINER ELECTRIC WATER VALVE September, 1993 Page 13 CMS1002W SERVICE SPECIFICATIONS When servicing a machine, it's helpful to compare that unit's operating characteristics to those of a new, clean, normally operating machine. What follows is that type of information: COMPONENTS Timer: Makes one complete revolution in 8 minutes. The harvest time is factory preset at 2 1/4 minutes. The harvest time is adjustable as required. Inlet Water Valve: Opens and admits 3/4 gallon per minute during the harvest cycle. [. . . ] Remove screws and pull the water solenoid valve out to gain access. Pull electrical cord connection from solenoid coil terminals. Remove inlet water fitting from the water solenoid valve. To replace the inlet water valve assembly, reverse the removal procedures. ELECTRICAL CORD SOLENOID VALVE Inlet Water Solenoid Valve Assembly To remove the inlet water solenoid valve assembly: 1.
