Replacing the lamp cartridge
Recommendation:
Because lamp alignment is critical to proper detector
operation, it is recommended that only Waters pre-aligned lamp cartridges be
used.
Required Materials
• #2 Phillips screwdriver
• Lamp cartridge
To replace the lamp cartridge
1. Power-off the detector, and disconnect the power cable from the rear
panel.
Warning:
To prevent injury, always observe Good Laboratory Practices
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:
Avoid electric shock:
• Do not open the detector cover. The components within are not
user-serviceable.
• Power-off and unplug the detector before performing any
maintenance operation on the instrument.
Caution:
To avoid damaging electrical parts, never disconnect an
electrical assembly while power is applied to the detector. To completely
interrupt power, set the module’s power switch to “off”, and then unplug
the power cord from the AC outlet. Wait 10 seconds thereafter before
you disconnect an assembly.
