Maintenance Considerations; Proper Operating Procedures - Waters ACQUITY UPLC Operator's, Overview And Maintenance Manual

Maintenance considerations

Safety and handling
Observe these warning and caution advisories when you perform maintenance
on your detector.
Warning:
when you handle solvents, change tubing, or operate the system. Know
the physical and chemical properties of the solvents you use. See the
Material Safety Data Sheets for the solvents in use.
Warning:
No user-serviceable parts are inside.
Caution:
• To avoid damaging electrical parts, never disconnect an electrical
assembly while power is applied to the detector. To completely
interrupt power to the detector, set the power switch to Off, and then
unplug the power cord from the AC outlet. After power is removed,
wait 10 seconds before you disconnect an assembly.
• To prevent circuit damage from static charges, do not touch
integrated circuit chips or other system instruments that do not
require manual adjustment.

Proper operating procedures

To ensure your system runs efficiently, follow the operating procedures and
guidelines in
Spare parts
Replace only parts mentioned in this document. For spare parts details, see
the Waters Quality Parts Locator on the Waters Web site's Services & Support
page.
Recommendations:
• For optimal baseline stability, keep the detector door closed at all times.
• Filter and degas solvents to prolong column life, reduce pressure
fluctuations, and decrease baseline noise.
To prevent injury, always observe good laboratory practices
To avoid electric shock, do not remove the detector's top cover.
