No you don’t.
The Air Still Pro automatically diverts and collects the foreshots into a small 30ml collection vial located on the side of the unit. Once the vial is full, a shut off ball will seal the foreshots in the vial below and then direct your distillate out of the collection tip and into your collection vessel.
Note: The vial must be installed correctly for the foreshots to be collected. The vial must be empty at the start of each run. If the vial is not installed, a secondary Stainless Steel ball stops the liquid from flowing out of the unit and onto your benchtop.
