Component Description CU0515Water Pump Water Circuit, Freeze Cycle Water Circuit, Harvest CycleThe water pump operates continually throughoutthe freezing cycle. The pump forces the water fromthe sump to the spray system and through thespray nozzles so it sprays into the inverted cupmolds to be frozen into crystal clear ice cubes.Water Inlet Solenoid ValveThe water inlet solenoid valve is energized onlyduring the defrost cycle. When energized it allowsa metered amount of incoming water to flow overthe evaporator cavity to assist the hot gas indefrosting the ice cubes.The water running over the evaporator cavity dropsby gravity, through the weep holes of the platen,into the sump.Hot Gas Solenoid ValveThe hot gas solenoid valve consists basically intwo parts: the valve body and the valve coil.Located on the hot gas line, this valve is energizedby the contacts 3-2 of the evaporator thermostatduring the defrost cycle.During the defrost cycle the hot gas valve coil isactivated so to attract the hot gas valve piston inorder to give way to the hot gas discharged fromcompressor to flow directly into the evaporatorserpentine to defrost the formed ice cubes.Bin ThermostatThe bin thermostat control body is located in thefront of control box behind the front louvered panel.The thermostat sensing tube is located into a bulbholder on the side wall of the ice storage bin whereit automatically shuts the ice machine OFF when incontact with the ice and re-starts the ice machinewhen the ice is removed. Factory settings are 1oC(35oF) OUT and 4oC (39oF) IN.Cube Size Control (Evaporator Thermostat)The cube size control (evaporator thermostat)body is located in the front of control box behindthe front louvered panel; it’s basically a reverseacting temperature control which closes contacts3-2 when its temperature decreases and closesthe opposite contacts 3-4 when the temperaturerises.July 2007 Page 8
