8 Service and maintenance of Fortuna cabinets
These cabinets are only safe as long as they are working properly. All components must be in full
working order to ensure safety for product, operator and environment.
Every 5000 operating hours or at least once every year the cabinet has to be
inspected and tested by a trained technician.
To ensure this, at least a yearly service and maintenance inspection is highly recommended. This
activity must be carried out by trained technicians and all appropriate safety measures must be taken
during this work.
Before repair work is carried out inside the contaminated and/or infected cabinet and
prior to filter replacement and upon change of location, proper cleaning and
disinfecting by the operator is required. The lab Manager/Safety Manager must
confirm this in writing to the service personnel.
Always disconnect the mains supply before doing any work on the electrical parts of
the cabinet. Failing this may cause electrical shock and damage to the electrical
components.
Before starting any service and maintenance work on the cabinet, conduct a general inspection to
evaluate the state of the cabinet.
After completion of the service and maintenance work, tests are required according to the standard.
Leakage test of downflow filter.
Test and adjustment of air velocities in downflow and alarm settings in the vertical downflow
inside the working chamber.
Test of air flow patterns.
The general function and safety tests must be performed in accordance with local requirements. For
this purpose we recommend a service and maintenance agreement.
All maintenance and repair work performed, as well as filter replacements and required tests, must
be documented in a test book.
