Installation recommendations for fittings
The system uses gold-plated compression screws and two-piece ferrules. See
the diagram below for assembly orientation:
Recommendations:
•
To prevent bandspreading, ensure the tubing is fully bottomed in the
fitting hole before tightening the compression fitting.
•
For easier accessibility, use long compression screws to attach tubes to
the injector and vent valve.
•
Perform the solvent manager leak test whenever you replace or loosen
fittings during maintenance (see the ACQUITY online Help).
•
Whenever you loosen fittings during maintenance, examine for cracks,
stripped threads, and deformations.
•
Do not re-use stainless-steel fittings more than six times.
