7.7 If Validation Fails
Should the system fail to satisfy any of the system validation check criteria, or should a
component fail to satisfy any of the component validation check criteria, proceed as follows.
• Check whether any consumable items have reached the end of their service
life :
The cause of failure to satisfy check criteria could be a consumable part that is no
longer usable. Check consumable parts and replace them if necessary.
• Perform troubleshooting :
It is possible that some minor problem (such as air bubbles) has caused the system to
fail the criteria.
Perform troubleshooting to check for such problems, and take action to eliminate any
problems found.
For troubleshooting procedures for individual system components, see the applicable
instruction manuals.
• If a cause cannot be determined, contact your Shimadzu representative :
If you are unable to determine the cause of the failure, or if you are unclear about
troubleshooting or corrective action procedures, contact your Shimadzu
representative.
