Prime the plunger seal-wash pump
The prime plunger seal-wash test automatically primes the solvent
management system plunger seal-wash pump. Perform this test if you discern
a lack of flow in the plunger seal-wash system or if you are changing the
seal-wash solvent. If required, use an intermediate solvent to prevent
miscibility or precipitation problems when changing solvents.
Required materials
• Seal-wash solution
• Tubing adapter (startup kit)
• Syringe (use only if no solvent is in the seal-wash pump)
To prime the plunger seal wash:
1. Ensure that the plunger seal-wash supply line (labeled “Inlet”) is in the
seal-wash solvent bottle and that the plunger seal-wash waste line
(clear) is in a suitable waste container.
2. Attach the tubing adapter (startup kit) to the syringe.
3. Fill the syringe with the seal-wash solution, and then connect the
syringe assembly to the seal-wash inlet tube.
4. Press the Prime SealWsh screen key in the Diagnostics screen.
5. In the Prime Seal Wash dialog box, press Start to begin the seal-wash
procedure.
6. Push on the syringe plunger to push seal-wash solvent through the
system.
7. When seal-wash solvent flows out the seal-wash waste tube, press the
Halt screen key.
Result: The seal-wash pump prime will time-out after fifteen minutes if
the test is not halted.
8. Press Close to return to the Diagnostics screen.
