Now that you have an understanding of how to work in the hood, we will
review the suggested maintenance schedule and the common service
operations necessary to maintain your hood for peak performance.
Only trained and experienced certification technicians should perform
some of the service operations after the 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.
Routine Maintenance Schedule
Weekly
• Clean the hood interior appropriate for the application.
• Operate the exhaust system, noting the airflow velocity through the
enclosure using a source of visible smoke. Airflow alarms are
recommended for constant monitoring.
Monthly (or more often as required)
• Determine the actual face velocity through the sash opening of the
hood where the average reading should be at the specified velocity.
(Use calibrated thermal anemometer or other approved apparatus).
Airflow alarms are recommended for constant monitoring.
• Using a cloth and glass cleaner, clean the exterior surfaces of the
hood, particularly the front of the hood, to remove any accumulated
dust.
• The hood rear baffle should be checked for any blockage to ensure
that the enclosure is maintaining proper airflow.
• All weekly activities.
