LED should change from green to orange. Once you are familiar with operating the system, you can
choose your preference of plenum or arm operation.
PLENUM OPERATION Place the plenum in front of the work area where fume extraction is necessary.
Plug the system in and click “On.” Fumes will be absorbed collected through the opening at the bottom of
the plenum. Impurities are then removed in the filter and clean air returned to the environment.
ARM OPERATION If you need the flexibility to move the fume collection device to the source of the
fumes, the BVX-100 easily converts for use with an arm. An arm and adapter come with the BVX-100
system for easy conversion to arm use. Make sure the system is “Off” and unplugged. Slide the adapter
into the plenum till it stops and secure it to the top of the plenum with the lock. Insert the cuffed end of the
arm into the adapter. Adjust the arm as needed.
The BVX-100 can also be used with bench-mounted arms normally used
with multi-user systems. Remove the arm and nozzle from the arm
adaptor assembly. Insert the 50mm hose, supplied with the arm, into the
arm adaptor assy.
“BLOCKED FILTER” LED INDICATOR When the unit is operating
properly, the LED indicator will illuminate green. If the HEPA or pre- filter
becomes clogged, the LED light will change to orange, indicating the blocked filter. The pre-and/or main
filter should be replaced until the light returns to green (see FILTRATION). The LED indicator will not turn
orange when the gas filter is saturated. Pre-filters should be replaced three to five times as frequently as
the HEPA filter. The gas filter life will be dependent upon the amount of gas vapor in the air stream.
“NO FILTER” SAFETY INTERLOCK The safety interlock is a switch that prevents the system from
operating open. This safety feature keeps the blower from operating when the unit is open to replace
filters, and it prevents the system from contamination if operation is attempted without a filter.
FILTRATION
Metcal fume extraction products are designed to effectively remove and filter fumes generated on the
electronics workbench. Two filter configurations are offered with the BVX-100.
For use in light to medium soldering and clean rooms, a 99.997% HEPA / activated carbon gas filtration
main filter is recommended. For light duty organic solvent and adhesive applications, a deep bed,
activated carbon filter is recommended. In both applications, a dual stage pre-filter is provided to retain
the large particles that can reduce filter efficiency and life.
Filter Replacement
A clogged filter will reduce the performance of your system. The BVX-100 monitors the airflow of the
system and the LED will change from green to orange when the filter is clogged. The unit will continue to
operate, but failure to promptly replace the filter may result in premature failure of the system.
Replacement of filters
1. Turn the unit off
2. Disconnect the power cord from the outlet on the system.
3. Unlatch the housing from the plenum (the latch is located on the back).
4. Remove housing off the plenum.
5. Replace the filter.
6. Replace housing on plenum and lock.
7. Reconnect power cord and turn system on.
8. If the LED is still orange, refer to Troubleshooting.
