building.
8.3.1.
SERVICE PANELS
The unit has four panels:
Service panel A
Service panel B
Exhaust panel
(do not open!)
Bypass panel
(do not open!)
The sash fasteners of the exhaust air panel and bypass panel must not be opened and are
factory sealed with screw varnish. Deviations from this are only permitted after prior consulta-
tion with technical customer service.
The service panels must be loosened by opening the sash fas-
teners. To do so, turn the sash fasteners 90° with the tool pro-
vided, in accordance with the direction of rotation shown in the
picture (right). The panel can then be lifted out of the unit by
holding
and
lifting
both
handles.
Ensure that the panel does not tip or slip out prematurely.
Only a suitable tool (inner triangle 8 mm) should be used for opening. A
suitable key (picture on the right) is included with the unit.
