WARNING
Before connecting the air exhaust hose,
make sure that the motor non-return valves
can rotate freely.
CAUTION
The installation must comply with the
r
egulations in force regarding the
v
entilation of enclosed environments. In
p
articular, discharged air must not be
c
onveyed into a duct used for fumes
d
ischarge or discharge from appliances using
g
as or other combustible materials. The use
o
f discontinued ducts is not allowed without
t
he approval of a qualified technician.
WARNING
After having replaced the filters, reinstall the
front stainless steel panel, otherwise the
Downdraft is not enabled to function.
Extraction options
This appliance is intended to suck cooking
fumes, greases and small amounts of steam. It
has been designed to work in both a ducted
mode with outside evacuation and recirculating
mode (using charcoal filters).
Ducted - Outside discharge version
The cooker hood can be mounted in the version
with outside discharge for extracted air: in this
case it is necessary to connect the ducting/
exhausting channel to the outside (exhausting
pipes are not supplied with the products.)
Unblock the motor non-return valve if required.
In case of outside air discharge installation, fit a
non-return valve to prevent wind and back air
from entering.
R
ecirulaton mode
In case fumes and vapour cannot be evacuated
outside, the appliance can also be used in
recircualtion mode.
Activated charcoal filters are required for
this type of installation (the DD605 requires
CAP27CF and the DD905 required CAP43CF)
Air recycled through the charcoal filters is
recirculated into the kitchen, thanks to a duct
conveying the air on one side of the cabinet
(Fig.11)
Removing the grease filters and
installing the charcoal filters
The removal and fitting of the grease and
charcoal filters need to be carried out with the
downdraft in the open position. To open the
downdraft, push the '1' key. Then remove the
front panel,
pushing the upper part of each side
at the same time. The panel will drop forwards
to make it possible to access the grease filters
(Fig. 6). Remove the grease filters to access the
carbon filters (Fig. 12). The replacement of the
charcoal filters has to be carried out accordingly
to the effective use of the Downdraft, and in any
case they should be replaced at least once every
6 months.
Connect the internal or external motor cable to
the terminal board found inside the plastic box
on the downdraft wiring. When performing the
electrical connection, take care to respect the
colours of the electrical wires and connect it
correctly (Fig 14).
