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.

SAFETY SWITCH LOCATION

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!
