UV Lamp Replacement
The coated low pressure mercury lamp has an expected lifetime of
at least 2,000 hours. To replace a lamp, proceed as follows, referring to
Figure B-1:
1. Unplug the optics module from the rear panel of the control unit.
Warning: Failure to unplug the optics module from the control unit
may expose the user to high voltage and UV radiation.
2. If the UV lamp has been on, allow the optics module to cool for 10
minutes before continuing.
3. Remove the filter tray (see Section 5.2) and the flow cell (see
Appendix A).
4. Remove the screws holding the optics module together and remove
the bottom half of the case.
5. Pull the old UV lamp out of its holder and unplug it from its
connector.
6. Plug the new UV lamp into its connector and insert it into the lamp
holder. Never handle the quartz surface of the UV lamp. Grease and
fingerprints will destroy the lamp.
7. Reassemble the optics module (do not over-tighten the screws).
