User Manual
Replacing the filters
Your device is equipped with FLEX™ filter technology that was configured to the user’s protection needs when the device
was purchased. The configuration of the filter column is dependent on the applications carried out in the enclosure. These
applications may change over time. Your FLEX™ filter technology can therefore be reconfigured if your fume hood is used
for applications other than those anticipated when the device is first set up. If so, please contact us so that we can verify that
the current configuration is safe or it needs to be configured.
The table below summarises all possible Flex™ filter technology configurations for your device
