Original instructions
The media of HEPA filters is fragile and should not be touched. Avoid
puncturing either HEPA filter during installation or normal operation. If you
suspect that a HEPA filter has been damaged, DO NOT use the cabinet;
contact a local certification agency or Labconco at 800-821-5525 or 816-333-
8811 for re-certification information.
The HEPA filters in the Procedure Station 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 Procedure Station:
• 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 procedure station for a
long period of time. Free chlorine will corrode stainless steel after
extended contact.
Procedure Stations should be decontaminated for any of the following
reasons:
• Before maintenance work requiring entry into contaminated areas.
• Before HEPA filter changes.
• Before performing certification tests requiring entry into
contaminated areas.
• Before relocating the cabinet.
• Before changing research programs.
• After the gross spill of biohazardous material or toxic chemicals.
