[. . . ] It is a reverse acting temperature control with double throw contacts. Turning its knob all the way counterclockwise also shuts off the ice maker. The control determines the length of the freezing cycle and correspondingly the size of the cube. A lower setting will produce a smaller cube, and a higher setting will make a larger cube. The cube size control changes its contacts when the evaporator reaches its preset temperature, starting the harvest cycle. When the sensing tube of the cube size control reaches the high preset temperature, the contacts change again, restarting the freeze cycle. The compressor toggle switch is located on the side of the control box. When moved to the OFF position, the other components will still operate. Water Pump The water pump operates during the freezing cycle only, pumping water through the spray nozzles into the inverted spray cups. Inlet Water Solenoid Valve The water solenoid valve, located in the back panel of the unit, is energized only during the harvest or cleaning cycles. When energized it allows a metered amount of water to flow into the machine (. 21 g. p. m. ) This water flows to the top of the evaporator and then down into the reservoir. Bin Thermostat Control The bin thermostat control body is located in front of the control box just beside the cube size control. The thermostat sensing tube is located in the ice storage bin on the left side wall where is automatically shuts the ice maker off when the bin is full and restarts when ice is removed. Factory settings are 1 degree C (36 degrees F) cut out and 4 degrees C (39 degrees F) cut in. It can be adjusted by turning the adjustment screw visible through the control box cover. Hot Gas Valve Assembly The hot gas valve assembly is comprised of two parts, the valve body and the coil. These parts are located on the discharge line of the compressor and are activated by the cube size control (harvest cycle). When the coil of the hot gas valve is energized, it magnetically lifts the plunger in the hot gas valve body. This allows hot refrigerant gas to by-pass the condenser and go directly to the evaporator. Spray Platform and Chute The spray system used on this unit is of the stationary type. The water is forced by the water pump into the platform chamber and sprayed into the inverted cup molds through a set of six spray nozzles. Fan Motor The fan motor is electrically connected through the cube size control and runs only during the freezing cycle. [. . . ] Wipe the interior of the bin with mild soap and hot water, rinse with cold water. To sanitize, mix a locally approved sanitizer solution and repeat steps 3-10, except substitute the sanitizer solution for the ice machine cleaner solution. A possible sanitizer solution may be obtained by mixing 1 ounce of household bleach with 2 gallons of warm (95-115oF) water. Caution: Do not use the ice produced during cleaning, as it may have a strong acid content. [. . . ]
