Now that you have an understanding of how to work in
the fume hood, we will review the suggested
maintenance schedule and the common service
operations necessary to maintain your fume hood for
peak performance.
Only trained and experienced
!
certification technicians should
perform some of the service
operations after the fume hood has
been properly decontaminated. DO
NOT attempt to perform these
operations if you are not properly
trained. The wrench icon precedes the
service operations that require
qualified technicians.
