It describes how the bottom grid maps one to one with the manifold columns and how flow requires engaging a waste pathway destination, such as column waste, to avoid no flow even though bottles are pressurized. It also covers the gas option for VLS models that pushes fluid back down through the column to agitate resin and help purging for certain syringe sizes. Finally, it clarifies that WashTM and EmptyTM are programs for washing and purging each Tridyl Monitor vial with ACN, respectively.
