•
Check the waste container daily and empty when needed.
Weekly
•
Once a week, check fluid lines for crimping or discoloration. Replace any
pinched lines. Replace damaged lines.
•
Check the junctions between the pump heads and the pump casting for
evidence of liquid leaks. If the 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 5.7 ).
•
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.
Every Six Months
•
Calibrate the cell (see Section 5.1.2 ).
•
Calibrate the vacuum degas assembly (see Section 5.1.4 ).
•
Replace the pump piston rinse seals and piston seals (see Section 5.7 ).
Yearly
•
Thermo Fisher Scientific recommends performing preventive maintenance
annually, as well as before scheduled Performance Qualification tests. A
Dionex ICS-1100 Preventive Maintenance Kit (P/N 057954) is available for
this purpose.
•
Rebuild the auxiliary valve, if installed (see Section 5.4 ).
•
If a Dionex AS Autosampler is installed, perform the preventive maintenance
procedure. The Dionex AS Preventive Maintenance Kit (P/N 060581) is
available for this purpose.
