5.8 Routine and Preventive Maintenance
The pump 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 pump 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 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 six weeks, a message appears in the
Chromeleon Audit Trail, reminding you to start a purge cycle.

Predictive Performance and Diagnostics
Chromeleon supports functions for estimating the lifetime of consumables and diagnostic
tests to check the performance of certain pump components (

pages 91 and 93).

ISO-3100 and HPG-3200
When the fluid components of the 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 pump.
Therefore,
before you open a fluid connection, position the reservoirs below the
connection to be opened.
Perform the maintenance procedures listed in the table at regular intervals to ensure
optimum performance and maximum uptime of the pump. The exact maintenance schedule
for the pump will depend on a number of factors.
Frequency What you should do...
Daily
Before you start operating the pump, inspect the fluid lines for air
bubbles and degas the solvent.
Check the fluid lines for indications of leakage.
Check the fluid connections for indications of salt deposits.
If the eluent is pure water, replace the eluent in the reservoir on a daily
basis.
Check the liquid level in the liquid reservoir of the rear seal wash
system.
