Removing / replacing xenon tube
Unscrew the grub screw (2.0mm A/F hexagon key) in the flange of the cover 3 full turns (Do not fully unscrew). Unscrew
and remove the cover and lens assembly using the spanner supplied to gain access to the inside of the unit.
Remove the old tube by unscrewing the terminal block fixings. The replacement tube can now be fitted (see xenon tube
installation sheet, which is supplied with the replacement tubes)
Once the new tube has been correctly fitted, replace the cover assembly, ensuring the cover is fully screwed down. There
should be a maximum gap of 0.2mm between the faces of the cover and enclosure to ensure o-ring compression. Ensure
the cover seal is correctly seated in its groove during re-assembly. Re-tighten the grub screw (2.0mm A/F hexagon key)
in the cover flange to secure the cover.
