the dimensions of the hood has to be cut out. The depth of this opening is 251mm. The width 472mm
or 652mm, depending on the model. The opening should be placed in the floor as centrally as possib-
le.
In any case the lower panel should not dominate the sides of the floor. Best would be, if the front
edges of the hood cover and the cabinet bottom were flush. However, care must be taken to ensure
that the remaining mounting frame has at least 20mm thickness so it does not endanger the cabinet
stability.
Installation
The hood is equipped with a clamping device. With
this the hood can be installed from the bottom by
clamping it to the mounting frame. The same opening
as in variant 1 has to be cut out. First the fixing
screws of the clamping device have to be loosened
from the outside (see picture right, point 1) with each
only half a turn. Now the clamps should be loose and
adjustable in heights and depths. Now the hood can
be put into the cabinet. Open the lower flap, remove
the grease filter and press the clamping noses from
inside back outside again. Then fix the clamps by
turning the wing nut (see picture right, point 2) down
until the hood is firmly trapped into the mounting
frame. Repeat this on the opposite side. The hood is
now attached and the flap can be closed after the
grease filter has been reinstalled.
Derivation of the exiting air flow
The air discharged from the hood, regardless of the use in the recirculation or exhaust mode, must
be discharged from the cabinet. In this respect, it is necessary to cut out another opening in the
cabinet ceiling at the same place as the air outlet of the extractor hood. Through this, either the
exhaust hose routed to the wall outlet or in recirculation mode a pipe or hose connection is created
that blows the air out of the cabinet. One end of the pipe or hose is to be connected to the hood on
the exhaust port, the other end leads out of the closet and if necessary to a wall opening.
If after installation of the hood there is no access to the space, the air duct should be installed before
installation of the hood. The same applies to the power supply.
Alternative use as a ceiling hood
Due to the high suction power, use as a ceiling hood is conceivable. Slightly disadvantageous affects
the low depth / width and thus smaller area coverage of the suction. In addition, there is no
possibility of lateral air outlet, which thus an installation height of at least 410mm, provided that the
connection of an exhaust air duct with lateral discharge is provided. For straight discharge upwards or
in recirculation mode with diffuse exhaust air distribution in the suspended ceiling, the height can be
reduced. Basically, however, and as well when installed in a cabinet, make sure that the air can
escape unimpeded and is not blown into a completely enclosed space. Even with recirculation an
outlet from a suspended ceiling has to be done in any case.
Otherwise, the attachment of the hood is analogous to installation in a cabinet.
