12. The HEPA filter provides Class 5 clean air conditions and only provides

product protection inside the enclosure. Do not use the enclosure for
personnel protection
.

13. Never use flammable gases or solvents in the enclosure. Use of an open

flame must be avoided in the enclosure. Open flames may disrupt the
airflow patterns in the enclosure, burn the HEPA filter and damage the
filter’s adhesive. Gases under high pressure should not be used in the
enclosure as they may disrupt airflow patterns.

14. HEPA filters are only effective for entrapment of particulate matter.

15. The surface of the HEPA filter is fragile and should not be touched. Care

must be taken to avoid puncturing the HEPA filter during maintenance. If
you suspect that a HEPA filter has been damaged DO NOT use the
enclosure; contact a local certification agency or Labconco.

16. The HEPA filter will gradually accumulate airborne particulate matter from

the room. The rate of accumulation will depend upon the cleanliness of the
room air, and the amount of time the enclosure is operating. With normal
usage, the HEPA filters will last two to five years before requiring
replacement.

17. Avoid direct exposure to ultraviolet (UV) radiation; NEVER work in the

enclosure when the UV light is on. Verify the sash is closed and the UV
closure panel is in place before turning on the UV light.

18. Ensure that the enclosure is connected to an electrical service in accordance

with local and national electrical codes. Failure to do so may create a fire
or electrical hazard. Do not remove or service any electrical components
without first disconnecting the filtered enclosure from electrical service.

19. Increase the downflow velocity by adjusting the speed control of the

motorized impeller or change the HEPA filter when the downflow velocity
falls below acceptable limits established by your Safety Officer.

20. Ensure only trained operators use the enclosure. New users should review

the User’s Manual and become familiar with the operation of the enclosure.

21. Proper operation of the enclosure depends largely upon the enclosure

location and the operator’s work habits. The enclosure should be located
away from traffic patterns, doors, fans, ventilation registers, fume hoods,
and any other air-handling device that could disrupt its airflow patterns.
