2.2 Operating modes
Exhaust air mode
In the version with exhaust air to the outside, the air drawn in
is freed from grease and fumes by the metal grease filter
and led outdoors through an exhaust air duct.
A backflow or inflow of outside air is prevented
by a non-return valve.
For exhaust air operation, the preconditions mentioned in the
installation chapter must be fulfilled and the corresponding
instructions must be followed exactly!
If implementation is not possible as described,
use the extractor fan only in recirculation mode!
WARNING!
Danger to life!
If the cooker hood and room air-dependent fireplaces
or appliances are operated at the same time,
insufficient supply air can cause a negative pressure,
which draws smoke and toxic combustion gases
back into the living spaces!
In this case there is a danger to life!
Inadequate installation can additionally result in fire
and health risks as well as operational malfunctions!
For exhaust air operation, observe and follow
the corresponding notes and instructions in the
installation chapter exactly!
