Original instructions
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.

reasons:
• Before maintenance work requiring entry into contaminated areas.
• Before HEPA filter changes.
• Before performing certification tests requiring entry into
contaminated areas.
