Read these instructions carefully. Only then 
will you be able to operate your appliance 
safely and correctly. Retain the instruction 
manual and installation instructions for future 
use or for subsequent owners.
The appliance can only be used safely if it is 
correctly installed according to the safety 
instructions. The installer is responsible for 
ensuring that the appliance works perfectly at 
its installation location.
The width of the extractor hood must 
correspond at least with the width of the hob.
For the installation, observe the currently valid 
building regulations and the regulations of the 
local electricity and gas suppliers.
When conveying the exhaust air, official and 
legal regulations (e.g. state building 
regulations) must be followed.
:Warning – Risk of death! 
Risk of poisoning from flue gases that are 
drawn back in. The exhaust air must not be 
conveyed into a functioning smoke or exhaust 
gas flue or into a shaft which is used to 
ventilate installation rooms that contain 
heating appliances. If the exhaust air is to be 
conveyed into a non-functioning smoke or 
exhaust gas flue, you must obtain the consent 
of the heating engineer responsible.
:Warning – Danger of death! 
Risk of poisoning from flue gases that are 
drawn back in.
Always ensure adequate fresh air in the room 
if the appliance is being operated in exhaust 
air mode at the same time as room air-
dependent heat-producing appliance is being 
operated.
Room air-dependent heat-producing 
appliances (e.g. gas, oil, wood or coal-
operated heaters, continuous flow heaters or 
water heaters) obtain combustion air from the 
room in which they are installed and discharge 
the exhaust gases into the open air through an 
exhaust gas system (e.g. a chimney).
In combination with an activated vapour 
extractor hood, room air is extracted from the 
kitchen and neighbouring rooms - a partial 
vacuum is produced if not enough fresh air is 
supplied. Toxic gases from the chimney or the 
extraction shaft are sucked back into the living 
space.
■ Adequate incoming air must therefore 
always be ensured.
■ An incoming/exhaust air wall box alone will 
not ensure compliance with the limit.
Safe operation is possible only when the 
partial vacuum in the place where the 
heat-producing appliance is installed does not 
exceed 4 Pa (0.04 mbar). This can be 
achieved when the air needed for combustion 
is able to enter through openings that cannot 
be sealed, for example in doors, windows, 
incoming/exhaust air wall boxes or by other 
technical means.
In any case, consult your responsible Master 
Chimney Sweep. He is able to assess the 
house's entire ventilation setup and will 
suggest the suitable ventilation measures to 
you.
Unrestricted operation is possible if the vapour 
extractor hood is operated exclusively in the 
circulating-air mode.
:Warning – Danger of death! 
Risk of poisoning from flue gases that are 
drawn back in. If installing a ventilation system 
in a room with a heat-producing appliance 
connected to a chimney/flue, the electricity 
supply to the hood must be equipped with a 
suitable safety switch.
