Steps for Replacing the Frit in the Solvent Line Filter
Open the filter holder and remove the filter frit.
Assemble the solvent line filter, wearing appropriate clean gloves:
- Place the frit in a level position in the filter holder (bottom part).
- Screw the filter top firmly to the filter bottom.
Slide the filter holder with the adapter onto the solvent line.
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.
To remove any air from the solvent lines, purge the pump using the solvent of your application.
