3.12 Maintenance
This section describes routine maintenance procedures that users may perform.
All other maintenance procedures must be performed by Dionex personnel.
As Needed
• Regularly check the eluent reservoir to see if it needs to be refilled.
• Make fresh eluent as needed.
Daily
• Check the ICS-1000 component mounting panel (see Figure 2-4) for leaks or
spills. Wipe up spills. Isolate and repair leaks (see Section 4.2
). Rinse off any
dried eluent with deionized water.
• Check the waste container daily and empty when needed.
Weekly
• Once a week, check fluid lines for crimping or discoloration. Relocate any
pinched lines. Replace damaged lines.
• Check the junctions between the pump heads and the pump casting for
evidence of liquid leaks. If piston seal wash tubing is not connected, check the
drain tubes at the rear of the pump heads for evidence of moisture. Normal
friction and wear may gradually result in small liquid leaks around the piston
seal. If unchecked, these leaks can gradually contaminate the piston housing,
causing the pump to operate poorly. If leaks occur, replace the piston seals
(see Section 5.6
).
• Check the end-line filter (P/N 045987) and change if needed. When new, end-
line filters are pure white. If the system is in continuous operation, change the
end-line filter weekly, or whenever it becomes discolored. Replace the filter
more often if bacterial buildup is visible or if the eluent does not contain
solvent.
NOTE It is especially important to regularly replace end-line
filters when using aqueous eluents, which may
contaminate the filter with bacteria or algae. The
bacterial buildup may not be visible.
