Follow the instructions for the maintenance procedure that you want to
perform:
•
When you replace the flush solvent, observe the guidelines in
Solvent Guidelines
•
When you replace flush purge lines, see
( page 165).
•
When you perform a flush purge cycle, see
Cycle ( page 171).
When replacing the flush solvent, with the same liquid or when changing
the flush solvent, observe the following:
•
Before filling the flush solvent reservoir, rinse the reservoir
thoroughly. Make sure that no particles, dust or algae are present.
•
Recommended when using 100% water as flush solvent replace the
flush solvent daily if the flush function is adopted.
•
Use a flush solvent that is suitable for your application and that
removes residual fraction from flush buffer loop sufficiently.
•
Check the liquid level of the flush solvent reservoir. Fill the flush
solvent reservoir with fresh flush solvent if required.
•
If you want to use a different flush solvent composition compared to
the current flush solvent composition, ensure that it is compatible
with the flush solvent used or change to the new flush solvent
stepwise.
•
After replacing the flush purge liquid
In Chromeleon, select Purge Flush Pump on the ePanel FC tab to fill
the flush pump with fresh flush solvent. During purging, the flush
pump and flush buffer loop are washed continuously until all flush
purge lines are filled with the fresh flush solvent. See
