Following the on-screen instructions and referencing the installation aid provided with the tubing set, make sure to insert the correct branch of tubing into each valve. Pay close attention to the tubing for valve 12. There are two branches of tubing at valve 12. The lower branch is the correct tubing for insertion, which ensures there is an unobstructed fluid pathway between the pre-column and column.
