Special Conditions For Safe Use - MEDC CU1 Technische Anleitung

Replacement of the xenon tube:
CAUTION: Before removing the cover assembly, ensure that the power to the unit is isolated.
Unscrew the grub screw on the lens cover assembly three full turns (2.0mm AF hexagon key required). Unscrew
and remove the lens cover.
Remove the old tube assembly by unscrewing the terminal block screws. The replacement xenon tube can now
be fitted into the terminal block provided.
Note: legs of xenon tube may need to be trimmed to allow tube to be fitted to the correct height from the termi-
nal block (see figure 2):
Once the tube has been fitted, replace the cover using the same procedure as above but in reverse manner. En-
sure the cover is screwed down tightly such that the maximum gap between the cover and enclosure is 0.2mm.
Tighten down the grub screw on the lens cover to secure the cover assembly onto the body. Ensure the o-ring is
correctly seated during re-assembly.
