2.2. Functionality of the system
The filter unit serves to suck off and filter polluted air (according to the intended use). First of all, the
coarse particles are separated at the prefilter mat in the filter section of the unit. The subsequent particle
filter cleans even fine smokes and dusts. The activated carbon filter absorbs gases and unpleasant
odours. An automatic filter monitoring indicates when a cleaning or a replacement of the filters is
necessary. The purified air is led back into the working room.
2.3. Intended use
The device is intended for commercial use. If the device is made publicly accessible, it must never be
operated unsupervised by authorized personnel, authorized by the operator.
The filter unit is intended for extraction and filtration of fumes that result from lasers or soldering jobs.
WARNING
Improper use can damage parts and be a danger to life and limb!
The device must not be used for the extraction of oil-laden welding fume, explosive dust
and gases, hybrid mixtures, glowing or burning substances, gases, water, etc. The
device must not be operated in explosive zones.
Dangers arising from fire.
If the sucked medium is combustible fume or dust, the operator must determine
beforehand which fire protection measures are to be taken.
2.4. Residual risk
CAUTION
Danger due to possible hazardous materials in the exhaust air flow.
Because the unit does not monitor the quality of the air in the exhaust air flow, we
recommend that you always guide the exhaust air flow exiting our unit to areas (e.g. to the
outside into the open air) in which there is no danger to any living being. To do this, it is
necessary to fit a suitable exhaust air line at the filter unit.

7. Maintenance
In accordance with national regulations, the operator is obliged to carry out repeat and functional tests.
Unless otherwise specified by national regulations, we recommend regular visual inspections and
functional tests of the device as described in the chapter “Maintenance intervals”.
You find the chapter “Maintenance intervals” at the end of the document. The general
maintenance (visual inspection, etc.) is also explained there.
In the chapter “Maintenance intervals” there is information on the maintenance intervals of the filter
elements. But these are only recommendations. Depending on the application (multi-shift operation,
dust generation, ...) it may be necessary for the operator to change the maintenance intervals.
In this chapter the maintenance work which is caused by wear caused during operation is described.
WARNING
Work on the open system entails the risk of electrical shock or accidental restart the
system. Both pose a danger to life and limb.
When cleaning and servicing equipment during the replacement of parts or when changing
to another function, set the device to maintenance condition first (see chapter “Reset to
maintenance state”).
A recommissioning of the device must only occur if it is ensured that the device is
functionally equivalent to the original state.
CAUTION
Hazards to the respiratory tracts are possible due to contact with contaminated filter
elements.
All maintenance work must only be carried out in well-ventilated rooms and while wearing an
appropriate respiratory mask! We recommend: respiratory protection half mask DIN EN
141/143 protection level P3. For all maintenance work ensure a cautious handling of filter
elements and components in order to avoid whirling up dust.
The operator is obliged to store and dispose of the collected dust in accordance with national or
regional regulations. For all maintenance or cleaning work please refer to the applying
environmental regulations. Pollutants and filter elements must be disposed of or stored according
to the regulations as well. If you have any doubts, we recommend contacting a disposal
contractor in your area.

7.2. Replacing the prefilter mat
The prefilter mat is installed upstream to the particle filter and separates the coarse particles. This
extends the service life of the particle filter.
The prefilter mat must be changed after a certain number of operating hours. The time depends on the
amount of accumulated dust, and therefore cannot be determined beforehand. At the latest, the prefilter
mat must be changed when changing the particle filter.
CAUTION
Whirling up dust is possible.
The prefilter mat is a disposable filter element. Do not try to clean the filter element.
● Open the service door of the particle filter housing (see chapter 2.1).
● Lower the lifting device (A) by turning the clamping screw (B). Therefore, use the hexagon key
that is located on the right of the clamping screw.
● Carefully pull the particle filter (see chapter 2.1) out of the housing.
● Remove the prefilter mat from the particle filter and dispose of or store it according to the
regulations.
● Put a new prefilter mat into the particle filter.
Only use TEKA spare filters. Otherwise the proper functioning of the unit is
not guaranteed.
● Push the particle filter back into the particle filter housing as far as it will go.
● Elevate the lifting device by turning the clamping screw so that the particle filter is pressed
tightly against the above housing.
● Close the service door.
