Pos. 9) is assembled under the
worktop. The installation is equipped with this to protect the interior of the installation against
pollution by coarse materials and to collect spilled fluids. Furthermore the pre-filter will enhance
the life span of the HEPA filter significantly.

Support frame (optional)
For a stable positioning of the cabinet, we strongly recommend the use of the especially designed
support frame from the supplier (
Figure 3, Figure 4, Figure 5
and
Figure 6,
Pos. 13).
This support frame includes an in steps adjustable feet support for a good ergonomic work
position (
Figure

, Figure 4, Figure 5
and
Figure 6,
Pos. 14). As well, the feet support will increase
the stability of the cabinet. In addition, it is recommended to use an in height adjustable, well
disinfectable chair to optimize the work position.
