5.10 Maintenance, and Maintenance and Calibration Intervals

5.10.1 General Information

The module is made of high-quality components and materials to minimize maintenance
requirements. All surfaces are resistant to weak acids, alkali, and organic solvents.
Nevertheless, immediately wipe up all liquids spilled onto the module surface, by using
lint-free cloth or paper. If surfaces are exposed for longer periods, these liquids can cause
damage.
Internal Maintenance
•
Every six weeks, the loading pump automatically performs an internal maintenance
procedure when you initiate a purge cycle. While internal maintenance is running, the
purge valve must remain open. When internal maintenance is complete, the purge cycle
starts automatically.
If no purge cycle is initiated after another 6 weeks, a message appears in the Chromeleon
Audit Trail, reminding you to start a purge cycle.
• NC pump
When the fluid components of the NC pump are filled with liquid and the solvent
reservoirs are located above the pump outlet during pump operation, the hydrostatic
pressure in the system may cause eluent to escape when you open a fluid connection in
the NC pump. Before you open a fluid connection, position the reservoirs below the
connection to be opened. Empty the solvents lines. If solvent shut off valves are installed
on the solvent lines, you can close the shut off valves instead.
• Predictive Performance and Diagnostics
Chromeleon supports functions for estimating the lifetime of consumables and diagnostic
tests to check the performance of certain module components (→ pages 132 and 134).
