Maintaining Your Enclosure
Now that you have an understanding of how to work in the enclosure, we will
review the suggested routine maintenance schedule.
Only trained and experienced certification technicians should
perform some of the service operations after the enclosure has
been properly decontaminated.
DO NOT attempt to perform these operations if you are not
properly trained.
Routine Maintenance Schedule
Weekly
 Clean the enclosure interior with a decontamination solution appropriate
for the application.
 Operate the exhaust system noting the airflow velocity. Airflow alarm is
used for constant monitoring.
Monthly (or more often as required)
 Verify the face velocity through the sash opening of the enclosure. (Use
calibrated thermal anemometer or other approved apparatus.)
Airflow alarm is provided for constant monitoring.
 Using a cloth and glass cleaner, clean the exterior surfaces to remove any
accumulated dust and increase visibility.
Annually
 Replace the fluorescent lamps as required.
 Have the enclosure validated by a qualified certification technician.
 Verify airflows and monitor calibration.
 Check HEPA filter for loading.
 Scan filters for leaks.
 If exhausted remotely, check for proper damper operation and balancing.
