This section applies to all pumps except the isocratic pump.
When
Damage or blockage of the solvent line
Parts and additional items required
Solvent line between pump inlet and proportioning valve or degasser inlet, as applicable for the pump
Solvent suitable for purging
Preparations
Empty the solvent lines (see Emptying the Solvent Lines).
Follow these steps
Retighten the reservoir cap hand-tight. The retaining guide must remain in the hole in the reservoir cap. If it does not, press the retaining guide into the hole so that the tubing is kept in place in the cap.
Remove the solvent line on the pump inlet and on the degasser.
Install the new solvent line.
To remove any air from the solvent lines, purge the pump using the solvent of your application.
