Note Because pump S does not have an associated flow sensor, the Pump S dialog box
does not include a Real Flow readback box.
Before using the direct controls to fill or empty pump A or B, make sure that the valves are in
the appropriate position. For information about controlling the position of the valves, see
"Using the Valve Controls"
IMPORTANT Before you fill pump A or B, make sure that the pump's associated valve is in
position 1–2. You can contaminate the pump by attempting to fill the pump when its
associated valve is in position 1–6.
❖ To fill pump A or B with solvent
1. On the Home > Overview page, check the position of the valve that controls the solvent
flow direction for the pump of interest.
2. Make sure that the valve is set to position 1–2.
When valve A or B is in the 1–2 position, the corresponding pump draws solvent from
the solvent bottle on top of the instrument (see
Using the Direct Controls for Troubleshooting and Maintenance
on page 165.
