DANGER
Risk of injury!
The sensor element is continuously exposed to the box gas and
therefore is at risk from contamination.
►
Ensure that all local and national safety guidelines are followed
when handling potentially contaminated materials.
！
NOTE!
MBRAUN recommends a maintenance cleaning procedure every 3
months.
CAUTION
Risk of damage!
When cleaning the sensors it is important that contamination from
the ambient atmosphere is prevented. Therefore, MBRAUN
recommends that the box parameters are set to a pressure of
b1.0 and +5.0 mbar ( see parameters chapter ) and that the
circulation mode is switched OFF.For Glove Box systems that must
remain at a negative pressure, special procedures may be required.
Contact MBRAUN service for advice.
