Routine Maintenance - Thermo Scientific EASY-nLC 1200 Troubleshooting And Maintenance Manual

Routine Maintenance

Thermo Scientific
To maintain the EASY-nLC instrument, follow the procedures in this chapter.
Tip You can access most of the instrument components by removing either the left or
right side panel of the instrument. Three captive quarter-turn screws secure each panel to
the instrument housing. To remove a side panel from the housing, loosen (unlock) the
screws from the housing by rotating them 90° counterclockwise. When loosened, the
screws rotate freely without constraint, but remain connected to the side panel.
For information about the suggested maintenance schedule and the built-in maintenance
scripts and record keeping features provided by the EASY-nLC touch-screen application, see
Chapter 3, "Maintenance Scripts and Service Records."
