General information

Exhaust duct
Note: The appliance manufacturer does not provide any
warranty for faults attributable to the pipe section.
The appliance achieves its optimum performance by means of
a short, straight exhaust air pipe and as large a pipe diameter
as possible.
As a result of long, rough exhaust air pipes, many pipe bends
or pipe diameters that are smaller than 150 mm, the optimum
extraction performance is not achieved and fan noise is
increased.
The pipes or hoses for laying the exhaust air line must consist
of non-combustible material.
If the exhaust air is conveyed through the outer wall, a
telescopic wall box should be used.
Risk of damage from returning condensate. Install the exhaust
duct in such a way that it falls away from the appliance slightly
(1° slope).
Round pipes
An inner diameter of 150 mm, but at least 120 mm, is
recommended.
Flat ducts
The inner cross-section must correspond to the diameter of the
round pipes.
dia. 150 mm ca. 177 cm
2
dia. 120 mm ca. 113 cm

Flat ducts should have no sharp deflections.
Use sealing strip for deviating pipe diameters.
Electrical connection
m
Risk of electric shock!
Components inside the appliance may have sharp edges. These
may damage the connecting cable. Do not kink or pinch the
connecting cable during installation.
The required connection information is on the appliance's
identification plate.
This appliance complies with the EC interference suppression
regulations.
This appliance must only be connected to a correctly installed
earthed socket.
Attach the earthed socket preferably inside the flue duct.
The earthed socket should be connected via its own circuit.
If the earthed socket is no longer accessible after installing
the appliance, an all-pole isolating switch (e.g. circuit breaker,
fuses and contactors) with at least a 3-mm contact gap must
be included in the installation.

Installation preparation

Checking the ceiling
The ceiling must be flat, horizontal and adequately load-
bearing.
The maximum weight of the extractor hood is 45 kg.
Appliance dimensions and safety clearances
Observe the appliance's dimensions. A
Comply with the safety clearances. B
If the installation instructions for the gas cooking appliance
specify a different distance, the larger of the two must always be
provided for.

Preparing the ceiling

The ceiling must be heat-resistant up to 90°C. The ceiling must
still be sturdy after the cut-outs have been made.
After making the cut-outs, remove any shavings.
Make the cut-out in the ceiling. (Fig. 1a)
1.
Affix the installation profiles. (Fig. 1b)
2.
Preparing the appliance
Open the filter cover. (Fig. 2a)
1.
Note: At an opening angle of approximately 40°, undo the
safety catch.
Remove the metal grease filter. (Fig. 2b)
2.
Adapt the holders to the thickness of the ceiling. (Fig. 2c)
3.

Installing the appliance

Note: Ensure that the filter cover is open during installation.
Grip the appliance by the housing frame and push it into the
1.
cut-out. (Fig. 3a)
Note: You must hear the holders click into place.
Tighten the screws in the holder. (Fig. 3b)
2.
Connecting the appliance
Notes
For exhaust-air operation, a backflow flap should be fitted. If a
backflow flap has not been included with the appliance, it can
be obtained from a specialist retailer.
If the exhaust air is conveyed through the outer wall, a
telescopic wall box should be used.
Establishing the connection for the exhaust air
Note: If an aluminium pipe is used, smooth the connection area
beforehand.
Remove the screws and open the flap downwards. (Fig. 4a)
1.
Attach the exhaust air pipe directly to the air pipe connector.
2.
(Fig. 4b)
Connect it to the exhaust air opening.
3.
Seal the joints appropriately.
4.
Establishing a connection to the mains
Plug the mains plug into the earthed socket.
Removing the appliance
Open the filter cover.
1.
Remove the metal grease filter.
2.
Undo the screws in the holder.
3.
Disconnect the appliance from the power supply.
4.
Remove the exhaust air pipe from the air pipe connector.
5.
Bleed the appliance.
