zone of the welder, make sure that all fume is
extracted through the hood.
• Put the unit off approx. 20 seconds after you have finished
welding.

periodic maintenance

The product has been designed to function without problems
for a long time with a minimum of maintenance. In order to
guarantee this some simple, regular maintenance and cleaning
activities are required which are described in this chapter. If
you observe the necessary caution and carry out the
maintenance at regular intervals, any problems occurring will
be detected and corrected before they lead to a total
breakdown.
WaRNiNg
Overdue maintenance can cause fire.
The indicated maintenance intervals can vary depending on
the specific working and ambient conditions. Therefore we
recommend to thoroughly inspect the complete product once
every year beside the indicated periodic maintenance. For this

Filter replacement

The service indicator (red LED) is on when the airflow is too
low.
Make sure that:
- the shut-off damper is open
- the extraction arm is not fully folded
When the service indicator stays on, you must replace the
filter cassette(s).
As the pre filter is smaller and becomes more quickly saturated
than the HEPA filter, you can replace the pre filter cassette
several times before you finally need to replace the HEPA filter
cassette.
WaRNiNg
Do not replace the filter cassettes while the fan is
running.
WaRNiNg
Do not shake out or (vacuum) clean the used filter
cassettes to avoid the release of particles.
