This chapter describes AS Autosampler service and repair procedures that the user
can perform. All procedures not included here, including electronics-related repair
procedures, must be performed by Dionex personnel. For assistance, contact
Dionex Technical Support. In the U.S., call 1-800-346-6390. Outside the U.S.,

Before replacing any parts, refer to the troubleshooting information in Chapter 4
to isolate the cause of the problem.
The CPU card contains a lithium battery. If the CPU card is
replaced, dispose of the used battery properly. Contact your local
government for disposal or recycling practices in your area.
