4.1 General safety instructions
● Read the safety instructions through
carefully before commissioning.
● Ask your installer to familiarise you with the
ventilation unit and the room air control
once the installation is completed.
● Keep these instructions somewhere safe.
● Ventilation unit and room air control should
not be used as toys.

● Change both air filters if the room air con-
trol filter change display appears and at the
latest, every six months. Only use original
filters.
● Filters should not be washed out as
otherwise the filter properties are lost.

pertinent regulations and guidelines.
The ventilation unit may only be installed
in rooms with air-ventilated fireplaces if:
● the evaluation criteria drawn up by the
responsible, regional master chimney
sweep are met,
● a parallel operation of air-ventilated
fireplaces for liquid or gaseous fuels and
the air-extracting equipment can be
prevented, or
● the extraction of exhaust gas from the air-
ventilated fireplaces is monitored by special
