4. Reconnect the fluid connections on the pump head. Observe the following:

When installing the capillary from the pump head to the purge unit, make sure that you
install the capillary in the direction of solvent flow, as indicated by the arrow on the
capillary. If the label is missing: Note that one side of the capillary is longer than the
other. Connect the longer side to the pump head.

When you attach the solvent line to the inlet valve, take care to avoid cross-threading.
5. Only HPG-3x00
Reconnect the pressure transducer cable to the P-Work connector on the interior front
panel.
Verify that the cable is properly connected. If it is not, messages relating the working
pressure may appear on the pump display, for example, 'Working piston pressure out of
range.'
6. Return the pistons into the appropriate position for normal operation. To do so,
perform the appropriate command for the pump head that you want to install:

On the Pump/Maintenance screen on the pump display, select Dock . Wait until the


In Chromeleon, perform the DockPistons command from the Commands dialog box
(listed under [Pump Device Name]_Wellness_RightBlock and/or [Pump Device

Rinse the pump with at least 30 mL of HPLC-grade water or pure organic solution.

Open the purge valve (with an ISO-3100BM, observing the precautions on page 90) to
prevent the rinsing liquid from entering the HPLC system.
9. Test the pump for leakage (

page 154). Tighten leaking connections.
10. Update the related service information in Chromeleon. To do so, perform the
PistonsChanged command for the pump head for which you replaced the pistons
(

page 91).
If you replaced the entire pump head assembly, perform also the SealChanged ,
CheckValveServiceDone , and SupportRingChanged commands.
