4. slide the filters out of the fume extractor and transfer
to a suitable disposal container.
5. Inspect the tubesheet and make certain the gasket
sealing area is free of dust to ensure proper sealing
of the new filter. make certain the area is dry after
the cleaning process is complete.
6. review internal cabinet including the bottom surfaces
and on top of the inlet baffle for accumulated
material. remove any accumulated material
manually or using a vacuum suitable for the collected
contaminant.
7. Install the new Protura nanofiber cartridge into the

on the fume extractor. door handle must be placed
at a 90° angle to filter access door prior to placing
the door cover plate support rod in the support
brackets. the flat surface of the door handle should
be facing downward. to close the filter access door,
push the door handle upward, toward the unit. the
filter access door handle must be in a perpendicular

respective joint.
to adjust the joint assemblies, simply tighten or loosen
the nylon lock nuts to the desired level of torque. the
tighter the nut is turned the higher the resultant friction
is created. for the elbow joints it is best to adjust the
two nuts by the same amount. small adjustments are
