4.1 REPLACING THE UV LIGHT
The UV light should be replaced after 6 months of continuous use. For this procedure, you will need a
Phillips head screw driver.
1. Turn off the computer and the Imager.
2. Unplug the power cord from the back of the Imager.
3. Disconnect the Imager Interface Cable.
4. Remove the Imager's Top Cover.
Slide out the gel holder to reveal two Phillips head screws obscured by the holder's front panel. Four
more Phillips head screws are located on the outer edges of the rear panel. Remove all six screws and
then lift off the Top Cover. Save the screws.
5. Detach the two Wire Bundles from the Reflector.
Be careful not to bend or distort the Reflector.
6. Remove the Reflector.
Locate and remove the shiny tent-like reflector held in place by two thumb screws. Be careful not to
bend or distort the reflector.
At this time you may wish to inspect the Excitation Filter and clean if necessary.
7. Remove the UV Tube.
Grasp and twist the UV tube 90° to release and remove it from the holder. Applying outward pressure to
the back of the Imager Chassis may help. When inserting a new tube, be sure to align it so that the
manufactures label faces upward toward the top of the reflector.
