13.6.2 Specific hazards
The device conforms to 2014/34/EU (ATEX) (equipment group II, category 3 and temperature
classification T4); it is exclusively intended for extracting air from Zone 2 or non-Ex zones and must be
installed in a safe area.
Marking:
II 3/-G Ex ec IIC T4 Gc
No specific hazards for people or the environment arise provided this equipment is used as intended
and only with original accessories, and provided this Installation and Operating Manual as well as the
information on safe commissioning are observed.
13.6.3 Operating principle, safe installation, commissioning, adjustment, installation /
removal, maintenance
The device is shipped ready to use and install with the exception of the control cables, which are not
included in the scope of supply because they must be adapted to the specific conditions on site. You
must check the electrical specifications (voltage, frequency) and compare them with the information on
the rating plate prior to connecting the device to the mains.
The device may only be installed, operated and maintained by appropriately trained,
instructed and authorised persons.

Operating principle: The air containing hazardous substances is discharged from the
hazardous material cabinet via a filter system comprised of a coarse filter, a fine filter and an
activated carbon filter. 99.9% of all hydrocarbons are retained in this way by adsorption. This
micro-controlled device monitors the volume flow and saturation of the activated carbon filter.
The operational status is indicated by three LEDs (GREEN, YELLOW and RED) as well as by
an audible signal. To meet the requirements of TRbF 20 Annex L, the exhaust function is
interrupted as soon as the saturation LED shows “Error”. This ensures that no hazardous
substances are discharged from the cabinet into the workroom. The interior of the device is
automatically flushed in the event of an error in order to reduce the concentration. If flushing
does not cause the concentration to fall below the setpoint, the device goes into “alarm”.
Alarms can only be cancelled by authorised persons. Short concentration peaks (less than 9
seconds) are simply indicated (all saturation lamps on) without the device going into “error”.
The coarse and fine filters significantly extend the life of the activated carbon filter by retaining
dust particles. The actual saturation up to the limit value is indicated by the three yellow LEDs
in 25% steps. The quality of the ambient air is shown by another yellow LED. The brightness
of this LED varies according to the amount of the hazardous substances.
•
Installation location: the capacity of the recirculating air filter is intended for cleaning the air
volume from the cabinet (cabinet volume x air turnover). Since the exchange air is taken from
the ambient air via cabinet air intake, it must be taken into account that the concentration of
pollutants is influenced by the composition of the ambient air. The total concentration of
pollutants before the filter is therefore composed of the sum of the cabinet and ambient
concentrations. When installing the cabinet, make sure that the ambient air is pollutant-
neutral. The device provides an indication of the quality of the ambient air using the four-level
All forms of use which deviate from or exceed the limits of use described above are
considered to be contrary to the intended purpose. The manufacturer / supplier is not
