The HEPA filters in the Biosafety Cabinet will gradually accumulate airborne
particulate matter from the room and from work performed in the cabinet.
The rate of accumulation will depend upon the cleanliness of the room air,
operating time and the nature of work being done in the cabinet. The Filter
Gauge accurately displays the amount of filter life remaining.
Proper operation of the cabinet depends largely upon its location and the
operator’s work habits. Consult the Installation and Normal Operation
sections of this manual for further details.
Avoid direct exposure of plastic or coated materials to ultraviolet (UV)
radiation. Never bypass the UV safety interlock that only allows the UV
light to work when the sash is closed. When surface disinfecting the
Biosafety Cabinet:
• Avoid splashing the disinfecting solution on skin or clothing.
• Ensure adequate ventilation.
• Carefully follow the disinfectant’s safety instructions.
• Always dispose of disinfecting solutions in accordance with local and
national laws.
• DO NOT allow disinfectants with high concentrations of free chlorine
to contact the stainless steel components of the Biosafety Cabinet for
a long period of time. Free chlorine will corrode stainless steel after
extended contact.
The electrical receptacle cover may be removed to facilitate surface
decontamination. In the event of gross contamination, the cover should
be removed, sterilized and/or decontaminated as required and discarded.
Order Replacement Receptacle Cover #1287900. See Appendix A:
