    Important: 

       • Each valve can be removed by being slid with the weight of the valve itself.
       • If the valve will not slide in this manner, push it out with a wire or face the valve inserting side downward and tap the valve lightly with rubber-headed hammer. Do not scratch the valve and damage its surface or hole.
       • Do not use a magnet. It may cause residual magnetism.
       • Be careful not to drop or lose the valve and internal components.
