4.3 Liquid Leaks
• Leaking fitting
Locate the source of the leak. Tighten or, if necessary, replace the liquid line
connection (see Section 5.3
). Refer to Installation of Dionex Liquid Line
Fittings (Document No. 031432) for tightening requirements. The manual is
included on the Thermo Scientific Reference Library DVD (P/N 053891).
• Broken liquid line
Replace the line and fittings with the same length and internal diameter tubing
(see Section 5.3
).
• Blocked or improperly installed line
Make sure the lines are not crimped or otherwise blocked. Also, if the blocked
line is a waste line, make sure it is not elevated at any point after it exits the
Dionex ICS-1100. If a line is blocked, replace it (see Section 5.2
).
• Loose pump check valve
1. Make sure the check valves are firmly seated in the pump head. If they are
not, tighten them carefully with an open-end wrench just until the leak
stops.
2. If the leak persists, replace the check valve (see Section 5.6
).
• Leaking seal wash port
Leaking from the seal wash port indicates a leaking piston seal. Replace the
seal (see Section 5.7
).
• Damaged pump piston seal
1. Replace the piston seal (see Section 5.7
).
2. If the leak persists, replace the piston (see Section 5.8
).
• Pump head not tight against casting
Carefully tighten the pump head mounting nuts just until the leak stops. DO
NOT OVERTIGHTEN!
