When
Damage or blockage of the solvent line
Parts and additional item required
Solvent lines from solvent reservoir to pump
Solvent suitable for your application
Parts affected
No. | Description |
|---|---|
1 | Solvent lines from reservoirs, routed to the pump through all modules above the pump in the system stack, with |
1a | Solvent line, channel A |
1b | Solvent line, channel B |
2 | Shut-off valves, A and B |
3 | Seal wash detector assembly |
Preparations
Empty the solvent lines. See Emptying the Solvent Lines.
If you want to replace the solvent line filter together with the solvent line, prepare the filter. See Replacing the Solvent Line Filter.
For easier access, consider removing the seal wash detector assembly (funnel and detector).
Removing the Seal Wash Detector Assembly
Grasp and pull the seal wash detector assembly (funnel and detector) upward by the funnel. The detector including the tubing and cable can remain connected to the funnel.

Removing the Solvent Line
Remove the solvent line from the reservoir cap:
- Remove the filter from the solvent line.
- Remove the retaining guide.
- Pull the solvent line out of the reservoir cap.
Disconnect the solvent line in the pump.
Remove the solvent line from the pump and all modules above the pump in the system stack. When removing the solvent line from the tubing guides, do not pull on other tubing in the guides.
Routing the New Solvent Line to the Solvent Rack
Connect each solvent line to the inlet port in the pump for which it is intended (see labeling on the solvent lines and in the pump).
Route the solvent lines from the pump to the solvent rack, through the tubing guides in the pump and all modules above the pump in the system stack. Observe the routing guidelines in Guiding Capillaries and Tubing Through the System.
Route the solvent lines through the guide hole in the solvent rack and push them into one or more of the tubing guides.

2 | Retaining guide |
3 | Reservoir cap |
4 | Cap plugs |
5 | Solvent line filter with solvent line adapter |
Feed each solvent line through a retaining guide.
Feed the solvent line through an open hole in a cap for a solvent reservoir. The retaining guide keeps the solvent line in place in the reservoir.
Close any open holes in the reservoir caps with the cap plugs.
Slide a solvent line filter onto each solvent line.
Tighten the reservoir cap hand-tight. Press the retaining guide into the hole in the reservoir cap so that the tubing is kept in place in the cap.
Position the solvent lines straight in the tubing guides.
Check the solvent lines across the entire flow path. Make sure that the lines are not bent, pinched, or squeezed at any point in the flow path.
If applicable, reinsert the seal wash detector assembly.
Purge the pump using the solvent for your application.
