MANUAL
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
Cooker hood damper control panel
A rotary, automatically closing damper equipped with a timer.
When turned to the right, the damper closes, switching on
the timer which will automatically close the damper in 60
minutes.
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.
Damper open
• 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.
WARNING
A G23 PL lamp will cause damage!

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 will be set o once
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.
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.

MANUAL
D11213/28.02.2020
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 from 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.

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.
• The static pressure loss is measured
from the hole in the damper
using the measuring tube found in
the accessory bag (see 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.
