Troubleshooting

f Remove the filter cassette from the appliance.
f If necessary, place a new filter in the filter cassette.
f Push the filter cassette into the appliance. Ensure that the
filter cassette is installed in the intended position. The arrow
on the filter cassette and the arrow on the appliance must
point in the same direction.
f To secure the filter cassette, turn the wing screw clockwise.
f Switch on the power supply to the appliance.
f After changing the filters, set the "Filter reset" to "On".
The unit resets the filter runtime to 0 and the "Filter reset" is au-
tomatically reassigned the value "Off". The filter change warning

Instructions, standards and regulations

WARNING Injury
!
In connection with the fire prevention regulations con-
cerning the installation of ventilation systems, observe
all country-specific regulations and requirements. In
Germany, these are particularly the building regulation
guideline on fire prevention requirements of ventilation
systems in its applicable version.
Note
Observe all applicable national and regional regulations
and instructions.
7.3 Operation of the appliance in buildings with
combustion equipment
The term "combustion equipment" used below includes, for exam-
ple, tiled stoves, fireplaces and equipment with gas combustion.
WARNING Injury
!
Ventilation units can generate negative pressure in the
dwelling. If combustion equipment is operating at the
same time, combustion exhaust gases can penetrate the
combustion equipment installation room. It is therefore
important to observe a number of points for simulta-
neous operation of a ventilation unit and combustion
equipment.
The engineering, installation and operation of the ventilation unit
and combustion equipment must be carried out in accordance with
national and regional regulations.
7.3.1 Planning safety measures
Together with the relevant authorities, engineers plan the safety
measures that are required for simultaneous operation of a ven-
tilation unit and combustion equipment.
Alternate operation
Alternate operation means that, when the combustion equipment
is commissioned, the mechanical ventilation system is switched
off and/or cannot be started. Alternate operation must be ensured
by appropriate measures, e.g. automatically enforced shutdown
of the ventilation unit.
