Model
Vallox X-Line PTXP MC
Type
27983-3
The Vallox X-Line PTXP MC control hood is suited to controlling SC or MC
ventilation units.
The cooker hood is designed to be used above the cooker top, as a general
extraction valve in the kitchen, and as a ventilation system control panel.

VENTILATION CONTROL
Apartment-specific ventilation units allow residents to
adjust the ventilation eciency.Ventilation is controlled
based on the need e.g. through the cooker hood,
ventilation control panel, or a separate control centre.
It is recommended that ventilation be left turned on
during long holidays also. This keeps the indoor air
fresh and prevents humidity from condensing in the
ventilation ducts and structures. It also reduces the risk
of moisture damage.
USING THE UNIT
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,
e.g., in the following situations:
• 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.

1. Away mode (position 1).
The ventilation eciency can be temporarily reduced
when the apartment is unoccupied.
2. Normal mode (position 2 or 3)
Ventilation must be continuous, i.e. the air inside the
building must be replaced at least once every two
hours.
3. Boost mode (positions 3-4)
Cooking, sauna, bathing, drying of clothes, excessive
heat, and other similar situations can require that
ventilation be increased from the standard setting. In
such a situation, ventilation must be increased. This
is done by boosting the ventilation either in general
or space-specifically. For example, the damper of
the cooker hood is kept open during cooking but is
closed or in the minimum position at other times.

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.

Signal light
The signal light shown in Figure 1 (A) is on when the MC
ventilation unit controlled by the hood is on. Signal light
flashing at one second intervals indicates that it is time
for maintenance of the ventilation unit. This reminder is
shown every six months. The service reminder is set o
when the door of the ventilation unit is opened. Other
reasons for the flashing of the signal light indicating
failure are described in the manual of the ventilation
unit. A
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.
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.
Replacing the lamp
• Remove the protective glass of the lamp by moving it
to the left (Figure 3).
• Remove the lamp by pulling it to the left (Figure 4).
• Lamp type: G23 LED.
Removing and mounting the grease
filter
• 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).

The signal light is not in
use if the hood is used
for controlling roof fans or
some other ventilation unit,
or if the signal light has
not been connected to the
ventilation unit.
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.
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.

Adjusting the fan speeds
A low signal voltage is coming to the control panel and,
therefore, the adjustment is made while the control
panel is connected and the ventilation unit is running.
• The adjustment is made by using the four holes
found underneath the knob of the ventilation
control panel (Figure 2) one speed at a time, by
using the potentiometer of the speed in question.
• The set voltage can be measured from the
measurement points found underneath the knob
of the control panel (markings S and -) or on
the terminal block underneath the black casing
(markings S and -, see Figure 6) by using the
DC voltage measuring of a universal meter. The
adjustment range is ~2…11.2 V.
• The control voltage (air flow) increases when the
potentiometer is turned to the right. The preset
voltages are 2.5 V, 5 V, 7.5 V, and 10 V.Please
note! Do not set the control voltage so low that
the fan does not stop (approx. 1.5 V).
An example of air flow adjustment:
Standard ventilation is adjusted at speed 2.
• Set the control panel to speed 2 and measure the
air flows from the valves.
• If the total air flow is too low, increase the control
voltage from potentiometer 2.
• If the total air flow is too high, decrease the control
voltage from potentiometer 2. Do not choke the air
flow unnecessarily by using valves!
• The balance between the supply and extract air
flow of the Vallox MC ventilation unit is adjusted
with the potentiometer inside the unit. Do not
change the supply/extract balance in connection
with measurements conducted at other speeds.
• Adjust the Away air flows similarly by using speed 1
(potentiometer 1).
• Adjust the Boost air flows similarly by using speed
3 (potentiometer 3).
• Speed 4 is usually reserved for the maximum
speed.
Set the ventilation control to
position 1 and remove the
knob by using a screwdriver,
for example
Measure the voltage from
poles – and S, set e.g. speed
1 from potentiometer 1
Measure the voltage from
poles – and S, set speed 2
from potentiometer 2, etc.
There are holes for
adjustments and
measurements underneath
the knob
Replace the knob, set the
ventilation control to the next
speed, and remove the knob
again.
You may also carry out
the measurement from the
terminal block, at the places
indicated by the wiring
diagram.
Lastly, measure the voltage of each speed from the
measuring pins and record them in the measurement
log. In e.g. terraced houses, the voltage measurement
can be used to “copy” the measurement made in the
first apartment to other similar apartments.
