CLEANING THE EXTRACTOR
Careful maintenance ensures the correct operation and optimal performance.
CAUTION:
The hood must be disconnected from the electrical network, both by unplugging the appliance
from the socket and activating the magnetic circuit breaker (safety cut-out), before removing the
metal grease filters. After cleaning operations, replace the metal grease filters as outlined in the
installation instructions.
MAINTENANCE HOW TO PROCEED? ACCESSORY PRODUCTS TO USE
Cleaning external
surfaces and
accessories
Do not use metallic scrubbers,
abrasive products, or hard brushes.
To clean the external surfaces of the downdraft
and the light housing screen use only commercially
available household detergents diluted in water.
Then rinse with clean water and dry with a soft
cloth.
Grease filters After 30 hours of operation, the
downdraft will signal the grease filter
saturation.
Saturation is indicated by the flashing
RED colour LED speed indicator, when
the cooker hood is off.
To reset, hold down the
Push button control panel (fig. 8)
A: 10 minutes timer, after which the motor is
turned off and the front is closed.
The setting of the function is signaled by
indicator(B) flashing.
B: The motor speed indicator.
The LED gives off four different colors, depending
on the set speed.
First speed color: WHITE
Second speed color: GREEN
Third speed color: BLUE
Fourth speed color: RED
C: The key is only active with open top (45° 90°).
For each selection of the function there is an
increase of the motor speed, up to the fourth
speed.
D: the key is only active with open top (45° 90°).
Each time you select the function you have a
speed decrease of the motor, up to the first
speed.
E: When the product is switched off, the first
touch activates the top panel until it reaches the
intermediate opening of 45°.
As the intermediate opening is reached, the
motor is automatically set to the 2nd speed.
Another press will start full opening (90°) of
the top panel, maintaining the speed of the motor.
Another press will stop the motor and completely
close the top panel.
NOTE:
- When the top panel is opened at 45°, hold down
the E button for 3 seconds, the top panel will
close and the motor turns off.
- When the top panel is closed, hold down the E
button for 3 seconds, the top panels opens by 90°
and the motor is activated at the second speed.
Warning: The product DD522BK allows the
opening of the glass top only by 90° (no 45°
opening is possible).
HOW THE
DOWNDRAFT WORKS
TIMING
As a result of the new EU65 “Energy label” and
EU66 “ Ecodesign” regulations issued by the Euro-
pean Commission, which came into force as from
January 1st, 2015 , our products have been adap-
ted to comply with these new requirements.
All of the models complying with the energy label
requirements, are equipped with new electronics
including a timer device for suction speeds control,
when the air capacity exceeds 650m³/h.
Internal motor models, with maximum air capacity
higher than 650m³/h, are equipped with a timer de-
vice that automatically switches the suction speed
from 4th to 3rd speed, after 6 minutes operation.
External motor models are equipped with remote
motors that , as for internal motor versions, inclu-
de a timer device that switches down the suction
speed when it exceeds 650 m³/h. (See External
Motors Instructions)
Remote motors, whose air capacity exceeds
650m³/h at both 4th and 3rd speed, will have the
following by default timer control functions:
The suction speed is automatically switched from
4th to 2nd speed, after 6 minutes operation.
If the appliance is working at 3rd speed, it is auto-
matically switched to 2nd speed, after 7 minutes
operation. Operation speeds can also be changed
during operation.
The energy consumption of the appliance in stand
– by mode is lower than 0.5W.
Other functions:
Automatic turn off:
After 4 hours of continuous operation from the last
setup, the appliance turns off automatically.
Grease lters saturation
After 30 hours of operation, the speed indicators
“B” will all flash simultaneously, signaling the
grease filters saturation. To reset this alarm, hold
the “TIMER” button down for at least 3 seconds,
while the extractable unit is open.

button for at least 3 seconds, while
the carriage is open.
The grease filters can be washed by hand or in
the dishwasher. These filters need to be cleaned
on a regular basis, because otherwise they may
represent a fire risk.
Refit the grease filters and front panel, making
sure that they are properly fitted at the sides
so that it does not cause the downdraft to stop
operating.
Active charcoal filter In the recirculation mode, the active
charcoal filter must be replaced
periodically.
To remove the charcoal filter first
of all, it is necessary to remove the
grease filter and then pull the plastic
key of the panel itself, in order to
disengage it from its seating.
Follow these steps in reverse order to
insert the active charcoal filter.
Replace the used charcoal filter on an
average of every six months.
