DESCRIPTION
Against fine dust during dust-forming work indoors
In exhaust air operation (for example for renovation work), the device is connected to the toilet connec-
tion with a flexible hose or is led directly into the open. The doors to the living area should be closed.
After the device has been commissioned, a negative pressure is created in the room, which prevents the
spread of fine dust in other rooms. In this operating mode, only the coarse air filter G4 is necessary.
In recirculation mode, the device is left in the room without leading the exhaust air into the toilet connec-
tion or outside. When the device is switched on, the air in the room is cleaned by the filters. The prere-
quisite for this is the optional fine air filter, type F7, which together with the existing coarse air filter, type
G4, filters the air accordingly as a pre-filter. In this operating mode, there is no negative pressure in the
room.
Dust particles are deposited in the device and can be effortlessly removed from the box after finishing
work.
Exhaust air operation
a) Switch off the Fine Dust Cube or remove the mains plug.
Remove the air filter fine, type F7. This is not needed.
b) Place the reducer on the exhaust air connection and
connect it to the exhaust air hose (6) that leads to the
toilet connection. Alternatively, use the exhaust air
hose (5) that leads to the outside.
c) Switch on the Fine Dust Cube and set the power output
with the power controller.
In order to create negative pressure to the other rooms,
you have to seal everything to the outside (windows, doors,
ventilation), otherwise the outside air will flow in and equa-
lize the negative pressure!
At the end of operation you should remove and clean the
filter (carefully knock it out or vacuum it out)
Recirculation mode (only with the fine dust filter option)
a) Switch off the Fine Dust Cube or remove the mains
plug. Insert the air filter fine, type F7. This opera-
ting mode should not be started without this filter.
b) Remove the reducer or any exhaust hose attached
to it from the exhaust air connection.
c) Switch on the Fine Dust Cube and set the desired
power level with the power controller.
At the end of operation, you should remove and clean the
filters (carefully knock them out or vacuum them out).
