6.3.3 Recirculation when using the cooktop
extractor as a recirculation system
In the case of recirculation systems there must be a
return flow aperture in the kitchen units:

> 500 cm² (per air cleaning box) in combination with
cooktops PKFI11, PKI11, PKIW1, PKC32, PKC3B,
PKCH2 and PKT11

> 1000 cm² (per air cleaning box) in combination with
gas cooktop PKG11
INFO If several extractor systems are operated in
recirculation mode, the return flow aperture
for each air cleaning box must be calculated
correspondingly.
Example:
2 recirculation systems = 2 x (> 500 cm²) or
2 x (> 1,000 cm²) in the case of gas appliances
For recirculation, the necessary return flow aperture can
be created using a shortened plinth. A slatted plinth with
at least the minimum opening cross-section can also be
used.
 Ensure that the return flow aperture is large enough.
6.4 Cut-out dimensions
INFO All dimensions from the front edge of the front
cover.
Worktop overhang
≥60
(

 Please note the worktop overhang x when creating
the worktop cut-out. Applies to flush installation and
surface mounting.
INFO For cooktop extractor PKA used in conjunction
with straight ducting piece PKA1FEV, flush
mounting is also possible for worktop depths
≥ 650 mm.

 Maintain the following safety clearances:
[1] Rear minimum clearance of 50 mm between the worktop
cut-out and the rear corner of the worktop.
[2] Minimum clearance of 300 mm from the left and right of the
worktop cut-out to the adjacent cabinet or wall.
[3] Minimum clearance of 600 mm between the worktop and
the wall unit.
6.3.2 Worktop and kitchen units
 Create the worktop cut-out taking into account the
specified cut-out dimensions.
 Make sure that the cutting surfaces of the worktops
are properly sealed.
 Comply with the instructions of the worktop
manufacturer.

Cross bars on the kitchen unit in the area of the
worktop cut-out may need to be removed.

No false floor is necessary below the cooktop. If cable
protection (false floor) is planned, the following must
be taken into account:

It must be fitted in such a way that it can be
removed for maintenance work.

To ensure sufficient cooktop ventilation, a minimum
distance of 15 mm to the bottom edge of the
cooktop is to be observed.

The drawers and/or shelves in the floor unit must be
removable.

For correct installation, the slide-in units of the
base cabinet must be shortened depending on the
installation situation.
