Checking for Leaks
To Correct Leaks in the Split Splitless Inlet
If the inlet fails a pressure decay test, check the following:
• Check the caps/plugs used in the test—make sure each is
correctly installed and tight.
• If you performed the leak test after performing
maintenance, check for proper installation of the part(s)
handled during the maintenance.
• Check the tightness of the septum nut. See To change the
septum on the split/Splitless inlet.
• Check the septum. Replace if old or damaged.
• Check the insert assembly installation.
• Check the liner and liner O- ring. See To change the liner
and O- ring on the split/splitless inlet.
• If you changed the gold seal, verify correct installation.
See To replace the gold seal on the split/splitless inlet.
• Make sure the inlet temperature remained constant during
the test.
If these items do not resolve the problem, contact Agilent for
service.
