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 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
