Ensure that OS2.0 is installed. Select the part which needs to be panned then set the part outputs parameter on the output menu to 1&2, 3&4, or 5&6. Now turn the pan pot fully anticlockwise or clockwise to pan the part to an individual output. Once this is done, the stereo effects applied to this part will need to be "panned" too. This is done from the pan menu. Set the pan effects option on.
