Replacing the UV Lamp
The intensity of the UV lamp, particularly the emission of short-wavelength radiation,
decreases over time. Replace the lamp after every six months of operation.
NOTE:
A cotton glove for wearing during the installation is included with
the replacement UV lamp to avoid leaving fingerprints on the quartz
window of the lamp. Fingerprints absorb UV radiation and decrease the
performance of the oxidation reactor. If necessary, use methanol to
remove any fingerprints before installing the new lamp.
To replace the UV lamp
1. If the Analyzer is taking measurements, click the
Stop Analysis
button.
2.
On the Analyzer’s

button to close all the
files.
3.
Turn the rotary power switch (located on the left outside panel of the Analyzer)
to the

Hazardous Material Disposal
The UV lamp contains mercury and may be considered hazardous material in your local
area. Dispose of these items in accordance with federal, state, or local government
regulations.
In the case of any broken or damaged UV lamp, handle the remains in accordance with
your organization’s toxic waste handling procedure and dispose of them in accordance
with federal, state, or local government regulations.
Warning
To avoid potentially dangerous shock, BEFORE opening the Analyzer,
stop any analysis and power off the operating system. Click the Power
On/Off

off
the power
switch and disconnect from the power supply. Any operation requiring
access to the inside of the Analyzer without turning off power, including
