3.12 Maintenance
This section describes routine maintenance procedures for the Dionex Easion that
users can perform. All other maintenance procedures must be performed by
Thermo Fisher Scientific personnel.
As Needed
•
Make fresh eluent.
•
Regularly check the eluent level and refill the eluent bottle. After refilling the
bottle, use the
Eluent Fill Volume slider on the Chromeleon ePanel to reset
the volume of liquid in the bottle.
•
Every time you refill the eluent bottle, also empty the regenerant bottle, rinse
it, and refill it with fresh regenerant.
Daily
•
Check the Dionex Easion component mounting panel (see Figure 2-2 ) for
leaks or spills. Wipe up spills. Isolate and repair leaks (see Section 4.2 ). Rinse
off any dried eluent or regenerant with deionized water.
•
Check the waste container and empty when needed.
Weekly
•
Check fluid lines for crimping or discoloration. Relocate any pinched lines.
Replace damaged lines.
•
Check the back of the pump head, as well as underneath the head, for
evidence of liquid leaks. 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 5.8 ).
Annually
•
Thermo Fisher Scientific recommends performing preventive maintenance
annually, as well as before scheduled Performance Qualification tests. A
To ensure the accuracy of the Eluent Fill Volume display, reset the
volume each time the eluent bottle is filled.
The regenerant bottle must remain filled all the way to the top at all
times.
