7.3 General Rules for Maintenance and Service
For successful maintenance and service procedures, follow these rules
and recommendations:
• Before starting maintenance or service procedures, shut down the
pump when instructed to do so.
•
Use only the replacement parts specifically authorized and qualified
for the pump by Thermo Fisher Scientific. For ordering information,
see
section 10.4 Consumables and Replacement Parts, page 223 .
•
Follow all instructions step by step and use the tools recommended
for the procedure.
•
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 pump, test the pump for leakage before you
resume operation.

If you need to return the pump for depot repair, follow the
instructions in
section 7.16 Transporting or Shipping the Pump,
