Maintenance procedure Frequency
Perform leak test As needed. For instructions on evaluating the
fluid-handling integrity of the system, see the
online Help regarding the following diagnostic
tests:
• Fluid integrity test
• Dynamic leak test
• Static decay test
• Set-pressure diagnostic test
Tightening of fittings As needed. For instructions on tightening
fittings, see the component’s overview and
maintenance guide on the documentation
CD.
Replace tubing As needed. For instructions on replacing
tubing, see the component’s overview and

Maintenance procedure Frequency
Replace the pump interconnect tubing As part of the annual scheduled routine
maintenance and thereafter, as needed. The
typical failure modes are as follows:
• You see a visible leak.
• The system exhibits a high-pressure
