For successful maintenance and service procedures, follow the rules and recommendations below.

General Rules

  • Before starting maintenance or service procedures, shut down the device when instructed to do so.

  • Use only the replacement parts specifically authorized and qualified for the device by Thermo Fisher Scientific.

  • Follow all instructions step by step and use the tools recommended for the procedure.

Using Fast Cool Mode for Maintenance Procedures

To cool down hot surfaces inside the column compartment quickly, use the Fast Cool mode:

  • Press the FAST COOL button on the keypad. When the LED next to the button is green, you can access the column compartment.

  • Cancel the Fast Cool mode when the procedure has been completed by pressing the FAST COOL button again. The Fast Cool mode can also be cancelled via the Chromeleon software (see Important Operating Parameters).

Opening Flow Path Connections

  • Before opening the flow path to replace capillaries in the system, turn off the pump flow and wait until the system pressure is down to zero.

  • Dirty components can contaminate the chromatography system. Contamination leads to poor performance of the modules and entire system or can even cause damage to the modules and system. Therefore:

    • Always wear appropriate gloves.

    • Place the components only on a clean, lint-free surface.

    • Keep your tools clean.

    • Use only lint-free cloth for cleaning.
