The Mobiflex 200-M(/HE) Base Unit is provided with a
Filter Maintenance Indicator "FILTER CLOGGED" (A).
When using the machine, regularly check the Filter
Maintenance Indicator. The red indicator slowly moves
upwards as filter cartridge becomes saturated or
clogged.

The Filter Maintenance Indicator
only functions when the fan is in
operation and the system is proper-
ly configured.

WARNING
Saturation or clogging of the filter
cartridge results in a decrease of
the extraction capacity which could
result in reduced extraction of weld-
ing fumes.
------------------------------------------------------------------------
• When the Filter Maintenance Indicator is entirely red,
replace the LongLife filter cartridge. See Filter
Replacement for description.
FILTER REPLACEMENT
WARNING
Take necessary precautions so that
you and your fellow workers are not
over-exposed to particulate. Wear
suitable personal protection equip-
ment, such as gloves, respirator,
eye glass and protective clothing
when disposing of the filter and par-
ticulate.
Check with local waste management (or local
agencies) for assistance in the disposal of filter. If
filter has collected certain types of particulate
which local agencies define as hazardous waste,
filter may be classified as hazardous waste and will
need to be disposed in accordance with federal,
state and local regulations - which could vary from
state to state, and between local municipalities
within the state.
------------------------------------------------------------------------
LONGLIFE FILTER CARTRIDGE
Replace the LongLife filter cartridge:
- When the Filter Maintenance Indicator (See Figure
B.5) shows that the filter cartridge is saturated or
clogged; or
- When the airflow is reduced to the point that extrac-
tion performance is no longer satisfactory; or
- When it has been damaged.
Replacement Steps:
See Figure B.6
1. Turn off the machine and disconnect it from the
input power.
2. Loosen the thumb nut (A) and remove the filter
