AEG 302D - Manual (Page 8)

General
The cooker hood can be used :
either as an exhaust air appliance (extraction mode)
or as a return air appliance (recirculation mode)
via a carbon filter (optional extra).
Preparation for installation
Extraction In this mode the fumes are extracted to the outside via a venting
mode hose connected to the coupling ring A, placed in hole B (fig. 1).
Depending on your installation the hose can be directed either
towards the ceiling or towards the walls(fig. 2).
In the extraction mode the outlet venting hose should to be
120mm in diameter, but 100mm or 110mm venting hoses can be
used by inserting the multiconnector flange (fig. 1), supplied with
the hood on the coupling ring A, before connecting the hood to the
outlet venting hose.
If the venting hose runs horizontal it must be slightly slanted
upwards (about 10°) to ensure the air is vented easily from the
kitchen to the outside.
If the hood is to vent out into the open air through an
external wall, you need a telescopic wall box (optional
extra). Wall box and venting hoses are available via your
AEG Stockist or AEG Spare Parts. Flame retardant venting
hose is available in 120 and 100mm diameter. Other flame
retardant materials such as KA piping can be used.
Optimum operation of the cooker hood in the extraction mode is
assured only if the following points afe observed:
- short, straight exhaust air runs
- as few hose bends as possible
- running of the hose in smooth flat arcs not at sharp angles.
- as large as possible hose diameter
Failure to observe these principles will result in serious power
losses and increased operating noise.
