5.2.2 Replacing lamps in the Epi-illumination module

Tools required: You will need a size 3/32" hex allenkey to change the lamps in the epi
illumination module
The VersaDoc has two epi-illumination modules each contain single white illumination source
and broad bandwidth UV sources. It is recommended that lamps in both the right and left
epi-assemblies must be replaced at the same time.
To change an epi-lamp, follow the procedure outlined below (Figure 5.3):
NOTE: The procedure to remove and replace the lamp in the UV or white light epi modules is the same. The
procedure outlined below applies to both.
1. Turn off the VersaDoc and disconnect all power, removing the power cable.
2. Open the door to the sample compartment.
3. Find the threaded mounting screw that secures the epi modules to the wall of the
enclosure and loosen it to free up the epi module from the wall.
4. Disconnect the epi module cables from the ballast assembly and remove the epi module
completely from the unit and set it on a clean bench.
5. Using a hex 3/32" key remove the three screws that secure the front end plate on the epi
modules and slide out the end piece and filter glass and set aside for future use. See
Figure 5.3.
