Priming a dry pump via the touchscreen

Priming the pump is part of the system startup workflow on the touchscreen.

To prime a dry pump via the touchscreen:

1. Open the pump’s front door.
   Note: The pump's door is the system's bottom door.
2. Locate the 0.062-inch vent valve solvent waste line located on the left-hand side of the pump bay, nested in the left bezel. Leave the 0.062-inch vent valve solvent waste line submerged into the process waste for now.

3. On the touchscreen, tap Setup > Solvents > Prime Mobile Phase Solvents and follow the on-screen prompts.
4. From the Prime Solvent by Solvent Line screen, tap Prime Solvent A, Prime Solvent B, Prime Solvent C, and/or Prime Solvent D.
5. Follow the remainder of the on-screen prompts to finish the priming process.
6. While the priming is in process, lift the 0.062-inch vent valve waste tube from the process waste manifold, exposing the end. You should see a steady flow of solvent after five minutes. Direct any flow into the top of the process waste cover (manifold) to prevent spills. If there is no flow, monitor solvent inlet lines A, B, C, and D to determine if they are filled with solvent.
   Tip: When solvent flows from the vent tubing continuously, the path is primed.

   Requirement: Ensure that enough solvent remains in the solvent reservoirs to supply subsequent methods.
