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.
