Maintenance and Servicing
8.3 Replacing fluorescent tubes
(only for models with interior lighting)
Caution:
►
Replace the fluorescent tubes only with fluorescent tubes of the same type; e.g. UV
light tubes only with UV light tubes, not daylight tubes. For information on the speci-
fications, please refer to chapter " Technical data " on page 17 .
►
Do not replace single tubes, but always the entire tube set (e.g. all UV light tubes
instead of just one). Replacing single tubes can influence the light output.
1. Loosen the connection of the illumination box in the interior. To do so, turn the bayonet
catch to the left and pull out the plug ( Fig. 34 ).
