extracted through the hood.
• Put the unit off approx. 20 seconds after you have finished
welding.
When the airflow is too low during use, the buzzer (ref. Fig.

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.

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

The buzzer emits an acoustic signal when the airflow is too
low.
When the buzzer still continues, 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.
