23.
Use the smallest possible quantity of chemical(s) within the enclosure
and never exceed the amount which can be effectively adsorbed by
the filters before breakthrough.
24.
Leave the blower on for at least one minute after work in the
enclosure has been completed.
25.
If a chemical is spilled on the work surface
DO NOT
switch off the
blower until all traces of the chemical has been removed.
26.
Make sure filters are installed prior to each use. Remove the front
panel to install the filters.
27.
If the blower fails during use, chemical processes should cease and
the area should be vacated and ventilated before servicing the blower.
28.
Always refer to the Paramount Chemical Guide and/or the NIOSH
Pocket Guide to Chemical Hazards before proceeding. For additional
help with filter and chemical selection, contact Labconco at 800-821-
5525 or 816-333-8811.
29.
The surface of the HEPA filter is fragile and should not be touched.
Care must be taken to avoid puncturing the HEPA filter during
installation or normal operation. If you suspect that a HEPA filter has
been damaged DO NOT use the enclosure; contact a local
certification agency or Labconco. Reference Chapter 6 for the HEPA
filter certification procedure.
30.
The HEPA filter in the enclosure will gradually accumulate airborne
particulate matter from the room and from work performed in the
enclosure. The rate of accumulation will depend upon the cleanliness
of the room air, the amount of time the enclosure is operating and the
nature of work being done in the enclosure.
31.
Ensure that the ductless 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 enclosure
from electrical service.
32.
Tag the enclosure with appropriate warning, if any filters have been
removed for service.
