12. Maintenance
Every 5000 operating hours or at least once every year the cabinet has to be inspected
and tested.
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 service personnel. For the appropriate form, refer to section 13.
After completion of work, tests are required according to the standard.
Leakage test of pre, main and exhaust air filter.
Test and adjust air velocities and alarm settings in the vertical flow inside the work chamber
and the horizontal in-flow in the work opening.
Test of air flow patterns.
General function and safety tests in accordance with local requirements.
For this purpose we recommend a maintenance agreement.
Before work on the electrical system, disconnect the power.
Fuses are accessible and situated on top of the cabinet (authorized person only).
All maintenance and repair work performed, as well as filter replacements and required tests, must
be documented in a test book. See section 12.
12.1 Filters
The HEPA filter is very fragile. Even a light touch on the filter surface may damage
the filter.
In order to avoid any possible harm, it is recommended that while changing filters the service
technician wears a mask with filter of HEPA quality. (H14 or better).
The used filters must be placed in special bags for biohazard waste immediately after removal. The
special bags should be handled as toxic material and sent for destruction as the normal toxic waste
from the lab.
