MANUAL
VENTILATION CONTROL
The removal of cooking smells can be enhanced by
using the adjustment damper of the hood. Potential-
free contact data is provided of the position of the
damper.
When Vallox X-Line KTXA is connected to the joint
extraction system of a multi-storey building, a Vallox
Smoke Limiter must also be installed.
USING THE UNIT
Front panel
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 by hand or in a dishwasher
at least 1-2 times a month.

Position of the damper
When turned to the left, the damper is in the closed
position: In normal circumstances, the damper must
be closed,
which boosts the extract air flow from other premises.
When turned to the right, the damper is in the open
position:
used when the extract air flow needs to be boosted,
such as:
• 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.

WARNING
The unit is not intended for use
by children under 8 or by persons
with reduced sensory, physical or
mental capabilities, or whose lack
of knowledge and experience do
not ensure safe operation of the
unit. Such persons can use the unit
under supervision, or by following
the instructions of someone who
is responsible for their safety. Do
not let children play with the unit
or to clean or maintain it without
supervision.
WARNING
If the ventilation of the apartment
is turned o, the entry of fresh
replacement air into the apartment
and the extraction of used air
from the apartment are prevented.
Impurities, such as carbon dioxide,
humidity, smells, formaldehyde,
dust, and radon, which come from
people, structures, and the soil
will quickly contaminate the room
air and are harmful to the health
of people. Excessive humidity
may damage the structures of the
building and result in mould and
fungal growth. For this reason,
building regulations require that
ventilation be turned on at all times
and that its eciency is adjusted
based on the needs of the user.
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.

Removing and mounting the grease
filter
INSTALLATION
Use the mounting accessories included in the package
to fasten the cooker hood in place.
1. Shorten the extract air duct to be connected to the
hood (125 mm spiral duct) to the correct length.
2. Where required, install a Vallox cover strip, for
instance, (2142400 cover strip 500 or 2142500
cover strip 600) to cover the opening in the rear
wall.
3. Lift the hood so that it is in contact with the duct.
4. Fasten the cooker hood with the mounting
brackets or by other means, so that the hood is
firmly in place and cannot move (figures 1, 2 and
3). The mounting screws included in the accessory
bag are suited to walls made of wood, chipboard,
cement or stone. Use appropriate mounting
devices for other materials.
5. Check the tightness of the extract air duct system.
6. Plug the cooker hood into the mains. Ensure that
the plug can be unplugged, where required.
• Open the quick connectors of the bottom plate of
the cooker hood by turning (Figure 1).
• Turn the bottom plate down.
• Remove the grease filter from its holder (Figure 2).

WARNING
A G23 PL lamp will cause damage!
CAUTION
The minimum distance of the
bottom edge of the grease filter to
an electric cooker is 500 mm, and
to a gas cooker 650 mm.
CAUTION
• The cooker hood must not
be connected to a flue that is
used for removing combustion
gases (e.g. from a wood- or
gas-burning fireplace, cooker,
or stove).
• The cooker hood must not
be fastened through the side
panels to the cabinets.
• Fans that are controlled
through the cooker hood must
have an engine cover and
their maximum power must not
exceed 340 W.
• Regulations on leading
extraction air outdoors must
be observed.

MANUAL
Measuring and adjusting the air flows
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 the figure).
• Determine the volume air flow based on the measured
pressure and the performance scheme (with the damper
open).
NOTE
If a Vallox Smoke Limiter has
been installed in connection to
the Vallox X-Line KTXA cooker
hood, adjustment of the boost
air flow must be completed in
accordance with the manual of
the smoke limiter.
