The peristaltic pump pulls the desired fluid through the system, disposing waste into a designated compartment inside the solutions pack. A second motor drives a lead screw which in turn drives a mechanical link-arm assembly. This link-arm assembly moves the sample probe vertically allowing the probe inside the solutions valve to aspirate the appropriate fluid for pumping: sample; standards; or air. The sample detector in the fluid line positions the fluids. Please note that mechanical and electrical assemblies can be replaced. Follow the instructions in the Troubleshooting section to determine if assembly replacement is necessary. Refer to the Replacement List in this section which lists replaceable assemblies, components, and appropriate catalog numbers. If repair to any electrical assembly is necessary, consult Schematics in the Appendix for further detail.
