• Clean the metal grease lter at least every other week to
prevent the built-up of fat residues on the metal grease
lter. These residues may catch re or ignites sponta-
neously. Replace the metal grease lter regularly and/or
if needed.
• To avoid generating excessive heat, do never operate
any cooking zone without a pot or pan or other cookware
on it.
• Never use open re near the devise.
• Never leave hot oil or fat unattended. Do never use wa-
ter when trying to extinguish any re caused by oil or fat.
Simultaneously using the device in the exhaust air fan
operation modus while operating any replace, furnace, or
oven operated with ambient air (such as heating applianc-
es red by gas, oil, wood or coal, instant-on water heat-
ers, water boilers or chimneys), consumes the ambient air
of the kitchen and the adjoining rooms (Fig. 5). This may
cause toxic combustion gases from the chimney or the
exhaust air shaft to ow back into the living areas inside
the apartment. Danger of suocation.
Therefore, you must in particular make sure of:
Employing a window ip switch to allow fresh air owing
in from the outside (Fig. 6).
A fresh air/ exhaust air wall sleeve does not provide su-
cient air supply. Please consult your competent chimney
sweeper who will evaluate the air supply and consumption
in your apartment.
The underpressure inside the room where the replace,
furnace, or oven is located must not be less than 4 Pa.
When using the device in the circulation fan operation mo-
dus, you do not need pay any particular attention to the air
supply and consumption in your apartment.
The device is powered by electricity; therefore, the danger of
an electric shock persists. Therefore, you must in particular
make sure of that:
• If an additional socket is required to connect the device,
you need to engage a professional electrician to perform
the respective installation.
• You will never touch the plug with wet hands.
• You will pay special attention to prevent the bending or
jamming of the power cable.
