12. The HEPA filter provides Class 5 clean air conditions and only provides
product protection inside the Clean Bench. Do not use the Clean Bench
for personnel protection.
13. Never use flammable gases or solvents in the Clean Bench. Use of an open
flame must be avoided in the Clean Bench. Open flames may disrupt the
airflow patterns in the Clean Bench, 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 the airflow patterns of the Clean Bench.
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 Clean
Bench; contact a local certification agency or Labconco.
16. The HEPA filter in the enclosure 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 Clean
Bench 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 Clean Bench 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 Clean Bench. New users should
review the User’s Manual and become familiar with the operation of the
Clean Bench.
21. Proper operation of the Clean Bench 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.
