Solvent suitable for purging the pump
Turn off the pump flow and wait until the system pressure is down to
zero.
Follow the steps for each solvent line in which you want to install a shut
off valve.
1. Unscrew the cap of the solvent reservoir and remove the solvent
line together with the cap from the reservoir.
2. Stop purging as soon as the solvent line is empty.
3. Retighten the reservoir cap hand-tight. Verify that the retaining
guide remains in the hole in the reservoir cap. If it does not, press
the retaining guide into the hole to ensure that the tubing is kept in
place in the cap.
