ICS-1000 Ion Chromatography System Operator's Manual

3 • Operation and Maintenance3.12 MaintenanceThis 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 orspills. Wipe up spills. Isolate and repair leaks (see Section 4.2). Rinse off anydried 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 anypinched lines. Replace damaged lines.• Check the junctions between the pump heads and the pump casting forevidence of liquid leaks. If piston seal wash tubing is not connected, check thedrain tubes at the rear of the pump heads for evidence of moisture. Normalfriction and wear may gradually result in small liquid leaks around the pistonseal. 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, endlinefilters are pure white. If the system is in continuous operation, change theend-line filter weekly, or whenever it becomes discolored. Replace the filtermore often if bacterial buildup is visible or if the eluent does not containsolvent.NOTEIt is especially important to regularly replace end-linefilters when using aqueous eluents, which maycontaminate the filter with bacteria or algae. Thebacterial buildup may not be visible.Doc. 031879-01 3/03 3-21
