8 Additional information on personnel safety and
protective measures
Adjustments and maintenance must be done only by trained service personnel. The potential sources of
harm are the fans with fast rotating impellers. The impellers are still a potential hazard even after power
cut-off because of after-run that can last up to 30 seconds.
The inspection doors are provided with a lock.
