Model BVX-203
This model features a deep-bed gas filter, which generally does not clog and
reduce airflow as 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 adsorbing moisture from ambient air.
Use only original Metcal
replacement
filters.
5.3 Safety Interlock
The safety switch is an interlock which
turns off the fan when the main filter is
removed and when the fan inlet opening
is exposed. The safety switch also
prevents the system from operating
without filters in which case the
impurities would contaminate the
internal unit.
WARNING!
Do not bypass safety interlock. Bypassing safety interlock could
result in injury to persons.
