Organic eluents are toxic above a certain concentration. Ensure that work

areas are always well-ventilated! When performing maintenance tasks

on the device, always wear safety glasses with side protection, protective

gloves, and an overall.
All wetted components of a device, e. g. flow cells of detectors or pump

heads and pressure sensors for pumps, have to be flushed with isopropa-

nol first and water afterwards before being maintained, disassembled or

disposed.

Users may perform the following maintenance tasks themselves:

Replacing the pump head

Exchanging the Ball Valves

Proper maintenance of your HPLC device will ensure successful analyses

and reproducible results.

8.1 Maintenance contract

The following maintenance work on the device may only be performed

by the manufacturer or a company authorized by the manufacturer and is

covered by a separate maintenance contract:
Opening the device or removing housing parts
