VENTILATION CONTROL
USING THE COOKER HOOD
The cooker hood has a sliding part that can be pulled
out of the cooker hood. Pull the sliding part out of the
cooker hood for maximal extraction capacity.
 Position of the damper
The damper is opened by pressing the damper button
(light turns on). The damper is closed (light turns o) by
pressing the damper button or automatically after one
hour (without a timer or 45-120 min when programmed).
In normal circumstances, the damper must be closed
(the signal light is o), which boosts the extract air flow
from other premises.
The damper must be open (the signal light is turned on)
when the user wants to increase the extract air flow
from the cooker hood e.g.
• when the cooker top or the oven is used for
cooking
• when the load in the kitchen is exceptional e.g. due
to the use of strong detergents or the presence of
a large number of people.
Touch the button on the damper to open it and to start
the timer. The damper will close automatically within 60
minutes.
Front panel buttons
The front panel of the cooker hood has two buttons
and two signal lights.
 Cooker hood light
Turn the light on or o by pressing the light switch. The
light is dimmable. Adjust the brightness by pressing the
light switch until the brightness is adequate.
Selection button
The selection button is roughly 3 cm to the left from the
damper button. The selection button is not marked on
the front panel.
CAUTION
• Neglecting the cleaning of the grease
filter can cause a fire hazard.
• The outer surfaces of the hood can
become hot when the cooker or the
oven is turned on.
• Flaming is forbidden underneath the
cooker hood.
• Always follow the instructions
provided on adjusting the eciency of
ventilation.
• Enable a sucient supply air flow
into the room if the cooker hood
and non-electric devices are used
simultaneously.
The removal of cooking smells can be enhanced by
using the adjustment damper of the hood. Poten-
tial-free contact data and 230 V 4 A supply voltage are
provided of the position of the damper.
When Vallox Delico KTD A is connected to the joint
extraction system of a multi-storey building, a Vallox
Smoke Limiter must also be installed.

MAINTENANCE
Keep the cooker hood clean. Wipe outer surfaces
regularly with water containing a small amount of a mild
detergent. Clean o any grease stains immediately. Do
not use abrasive or corrosive detergents or tools.
Keep the grease filter clean to ensure an adequate
extract air flow. The grease filter must be washed with
warm water and detergent at least 1-2 times a month.
Removing and mounting the grease
filter
12
• Pull the sliding part out of the cooker hood.
• Pull the locking device of the grease filter towards
the front edge of the cooker hood while pulling the
grease filter downwards until it comes o.
• Wash the grease filter and leave to dry.
• Mount the grease filter back in place. Push the
front edge of the filter into the pins on the cooker
hood, and click the rear edge in place.
Other functions
Guard function
The cooker hood has a guard function that is activated
when the temperature of the cooker hood exceeds +60
°C or after a sudden increase in temperature (> 8 °C/
min). In such a case, the damper of the cooker hood
closes and all signal lights of the cooker hood and the
LED light will flash. If this kind of alarm is noticed before
fire damage, it can be acknowledged by pressing any
of the cooker hood buttons.
Pre-selection of light brightness
To modify the pre-selection of light brightness:
1. Turn the light on and close the damper.
2. Press the selection button for roughly 3 seconds
until the setting mode signal light starts to flash.
3. Adjust the brightness of the light by pressing the
light button until the brightness is adequate.
4. To save the setting, press the selection button for
roughly 3 seconds until the setting mode signal
light stops to flash.

button, go to our website, www.vallox.com.

MEASURING AND ADJUSTING PERFORMANCE VALUES
Standard ventilation
The volume flow rate of the air inside the cooker hood is
measured with the damper closed and, where required,
adjusted based on the static pressure loss and the
performance scheme of the cooker hood.
• Measure the static pressure loss of the cooker hood by
pushing the probe through the hole in the damper (see
the figure).
• Determine the volume flow rate from the performance
scheme based on the measured pressure and the number
of open holes in the damper.
Adjustment:
• Cover the required number of holes in the damper with
the magnetic strip that is delivered with the cooker hood.

Boost ventilation
The volume flow rate of the air inside the cooker hood
is measured with the damper open based on the static
pressure loss and the performance scheme of the cooker
hood.
• Measure the static pressure loss of the cooker hood.
The measuring point must be located 2 times the duct
diameter above the outlet collar of the cooker hood (see
figure).
• Determine the volume air flow based on the measured
pressure and the performance scheme (with the damper
open).
