When replacing the fluorescent tubes, observe tube orientation (inscription).
How to replace the fluorescent tubes is described in chap.16.2.
Operation with light cassettes and illumination on: Maximum temperature 60 °C / 140 °F.
Operation with light cassettes and illumination off: Do also NOT operate the unit at tempera-
tures >60 °C / 140 °F. Otherwise, the lifetime of the fluorescent tubes will be considerably re-
duced.
When operating the chamber at temperatures > 60 °C / 140 °F, remove the light cassettes.
Entering the set point values for KBF P when operating without illumination:
• Adapt the setting of the temperature set-point according to the table in chap. 8.2.
• Adapt the setting of the humidity set-point according to the table in chap. 8.2.
