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.

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.

  • After you have performed maintenance or service on the flow connections in the system, do the following: First, test the system for backpressure (script: D01 - Test System Back Pressure), then, test the system for leakage (script: D02 - Test System Tightness (What Should Be Tested = System)).

NOTICE

Flow connections and capillary connectors are highly sensitive to contamination. Dust and debris can contaminate these connections.

Always install caps onto capillaries and plugs to open flow connections to protect them from contamination.

Depot Repair

  • If you need to return the system to Thermo Fisher Scientific for depot repair, contact your local Thermo Fisher Scientific support organization for the appropriate procedure.
