Check the second and third cube harvest. Ensure that they are the correct size and make adjustments to the Ice Sensors Fingers as Wiring Diagrams necessary. In certain areas where there are extreme water problems it may be necessary to fit a filter or purifying equipment. NOTE. If the water is too soft (demineralized) the Ice Thickness Sensor may not be able to sense the water on its fingers, thereby not switching the unit onto the harvest cycle. In the event of this occurring a safety system bu
