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.
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.
