The SterilGARD Biosafety Cabinet is shipped with a protective laminate sheet covering the exhaust HEPA
filter. Removal of this sheet shall be done by the certifier, NOT THE INSTALLER, because of potential
damage during installation. If this protective sheet is not present after installation, inspection of the exhaust
HEPA filters is strongly recommended. Filter replacement maybe necessary if damage found cannot be
repaired.
Step 1 : If equipped with FlexAIR Canopy Exhaust Connection, be sure to have the exhaust air turned on and at
the specified exhaust flow range before beginning the cabinet airflow validation procedure. (See Baker Document
BAKD066 for exhaust airflow requirements)
To meet manufacturer’s specifications, all methods and acceptance
criteria must be followed. No alternative or secondary methods for
measuring cabinet airflow other than what is stated in this service manual
and the cabinet data plate shall be used to validate the performance of this
biosafety cabinet.
