Single choice
Water is delivered to ice-cube trays that are placed in freezers at less than -6?centigrade. The trays are removed from the freezers after six hours. If the water has not completely frozen, the trays are returned to the freezer until freezing is complete. The ice-cubes are then removed from the trays, inspected, and placed in bags. Defective cubes are discarded. The bags filled with cubes are kept in storage freezers.
Alarms are sounded if a freezer's temperature goes above -6?centigrade. It has been shown that water in the ice-cube trays will freeze in six hours at -6?centigrade or less.
