5. Installation
5.1 Unboxing & Set-up
Remove the Fume Extraction System from the packing materials and place it on the
floor under the workbench or near your work area where fume extraction is required.
Make sure you have access to the unit for filter maintenance.
Connect the Unit power cord into the main power input on the back of the system.
Plug the power cord into a grounded wall outlet.
Warning!
To provide protection against the risk of electrical shock, connect to properly grounded
outlets only.
Connect the Unit to hoses/arms (optional) per installation instructions. To power up
the system, press the power switch located on the top right side of the Unit (“I”
indicates the “Power On” position). The operator can expect a delay of a few seconds
before hearing the fan running. This is due to a built-in motor “Soft-Start” feature.
Position the arms/hoses to optimize the fume capture.
Follow maintenance procedures below.
Attach the Nozzle to the Hose
1. Connect the nozzle to the hose by pushing it until it stops.
2. Turn the nozzle clockwise to ensure the nozzle is attached firmly to the hose.
3. Insert the nozzle filter into the top of the nozzle -ensure it clicks into place.

6. Communication with ConnectionValidation™ (CV) and GT
Series Soldering Systems
The BVX-250 Series Fume Extraction System can communicate with a connected Metcal
CV or GT Series soldering system. (A firmware update may be required)
Simply connect a USB-A to USB-A cable between the USB port on the BVX-250 and the
USB port on the CV or GT Series soldering station.
IDLE MODE
When the BVX-250 is connected to a CV or GT soldering system, it will go into idle mode
(indicated by the LED ring turning blue) when the connected soldering system is in an
idle mode. The GT goes into idle/sleep mode when the handpiece does not move for a
set time (selectable). The CV will go into idle/sleep when the tip is in the sleeper stand.
If the BVX is connected to two soldering systems, both systems need to be in idle mode
to trigger idle mode on the extraction system. When the connected soldering station is
no longer in idle/sleep mode, the BVX unit will resume normal fume extraction.
SCREEN ALERTS
The screen on the connected CV or GT soldering system will now display alerts sent
from the fume extraction system that correspond to the messages conveyed by the
LED ring:
•PRE-FILTER (SOLID OR FLASHING AMBER LED RING): If the pre-filter needs to
be changed or is not installed correctly, a popup will appear on a connected
soldering system.
•FILTER (SOLID OR FLASHING RED LED RING): If the main filter is blocked or not
installed correctly, a popup will appear on a connected soldering system.

7. Maintenance and Cleaning
7.1. Filter Unit - Maintenance and Safety
The Fume Extraction System is designed with low maintenance in mind. The
housing is ESD-safe plastic. Here are a few tips to keep your system running in
top shape:
To clean, use a light wipe with a gentle cleaner to prevent buildup of particulate
and flux residue (be sure the Unit is turned off while cleaning).
Do not block the exhaust outlets; this will cause the operating temperature of the system
to rise, potentially damaging the Unit, and causing a drop in performance.
Do not defeat the filter interlock switch. Running the system without a filter will allow
particulate and flux residue to adhere to the blower and decrease the life of the system
and increase noise.
Do not lift the system while operating.
Be sure to handle filters with care.
7.2. Filter Replacement Timing
HEPA/Gas Filter
When fumes are filtered inside the Unit, the particulates captured will start clogging
the filter over time. The coarse particles are collected in the pre-filter while fine
particles will be collected in the HEPA 13 filter. The clogging will result in a reduction
of the airflow, which may reduce the number of fumes extracted from the work area.
This condition may not necessarily require filter replacement. One step is to move
the optional extraction arms closer to the application if possible. If the fumes are not
extracted any longer to previous satisfaction level, or when the LED light changes to
RED or AMBER, filter replacement is required. See section 7.4 for filter replacement
procedures.
Warning!
Do not attempt to clean filters. Attempted cleaning can damage filters and cause
potential risk to health and equipment.
Notice: Metcal recommends replacement of main filters annually as a minimum. Regular
changing of the pre-filter will prolong the life of the main filter (HEPA/Carbon). Use only
original replacement filters.

15
BVX-250 Series Fume Extraction System
User Guide
Optional Deep Bed Gas Filter
Deep bed gas filters generally do not clog and reduce airflow as is common with
HEPA filters. Replace both filters, pre-filter, and carbon filter, as soon as odors
become noticeable.
Notice: Replace filters at least every 6 months, as most gas-phase filter media achieve
saturation by absorbing moisture from ambient air. Use only original replacement filters.
7.3. Safety Interlock
The safety switch is an interlock which deactivates the fan
motor when the main filter is removed, allowing the fan inlet
opening to be exposed. The safety switch also prevents the
system from operating without the filters, which would allow
impurities to contaminate the internal unit.
WARNING!
Do not bypass the safety interlock. Bypassing the safety interlock could result in injury.
7.4. Filter Replacement Procedure:
1. Turn the Unit off.
2. Disconnect the power cord.
3. Remove and replace the Pre-filter (see illustration below).
4. Remove and replace the Main filter (see illustration below).
5. Reinsert the filter by lining up the white dot on the filter holder with the white
dot at the top of the opening. Slide the filter into place.
6. Secure the filter holder by turning it 90 degrees clock-wise. The Metcal logo
should be right-side-up and parallel with the floor.
7. Reconnect the power cord and turn the system on.
8. If Unit does not operate, refer to the Troubleshooting section.
Notice: Always use new replacement filters!
