Leaking pressure transducer

1. Make sure the liquid line connections into the pressure transducer are

tight. Refer to Installation of Dionex Liquid Line Fittings (Document No.
031432) for tightening requirements. The manual is included on the
Dionex Reference Library CD-ROM (P/N 053891). Replace any
damaged fittings.

2. If the pressure transducer continues to leak, contact Dionex for assistance.

The pressure transducer cannot be serviced by the user.

Leaking pump head waste valve

Make sure the waste valve is closed. To close the valve, turn the knob
clockwise, and tighten fingertight. DO NOT OVERTIGHTEN!
Overtightening may damage the valve and the pump head.

If the leak persists, replace the waste valve O-ring (see

Section 5.9

).

Leaking suppressor

Refer to the suppressor manual for troubleshooting procedures. Suppressor
manuals are included on the Dionex Reference Library CD-ROM
(P/N 053891).

Leaking injection valve or auxiliary valve

1. Make sure the liquid line connections to the transducer are tight. Refer to

Installation of Dionex Liquid Line Fittings (Document No. 031432) for
tightening requirements. The manual is included on the Dionex Reference
Library CD-ROM (P/N 053891). Replace any damaged fittings.

2. Liquid leaks from behind the valve stator may indicate a scratched rotor

seal. Rebuild the valve (see

Section 5.4

).

Leaking detector cell

1. Check the waste lines for blockage; trapped particles can plug the lines

and cause a restriction and/or leak. If necessary, clear the waste lines by
reversing the direction of flow.

2. Make sure the plumbing downstream from the cell is clear; a blockage

may overpressurize the cell, causing it to leak. If the problem continues,
contact Dionex for assistance.
