INTRODUCTION
There are two unit models, left- (L) and right-handed (R). In the
right-handed version, outdoor air blows into the unit from the
right. In the left-handed version, outdoor air blows into the unit
from the left side. The location of the filters, bypass damper, and
heating radiator is also mirrored in the left-handed model.
VENTILATION UNIT CONTROL
Ventilation unit control options.
Operation of the Vallox ventilation unit can be controlled by the
following means:
• Through the My Vallox Control control panel installed in the
building.
• Through the MyVallox Home local area network connection
and the MyVallox Home/Cloud user interface.
• Through the MyVallox Cloud cloud service and the MyVallox
Home/Cloud user interface.
• Through a remote monitoring service or building automation
that uses voltage signals or Modbus messages.
In addition to the integrated humidity sensor, ventilation can
also be adjusted automatically by using the optional carbon
dioxide, humidity, or VOC (air quality) sensor. When these are
used, ventilation remains optimal even when the dwelling is
unoccupied. Each user can use the week clock to adjust the
ventilation to fit their individual lifestyle.

MV
Vallox 51K MV
The Vallox 51K MV ventilation unit is controlled by using the
Vallox Captura cooker hood that is connected to the unit. 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.
The front panel of the cooker hood has four buttons.
Position of the damper
The damper is opened by pressing the damper button
(signal light turns on). The damper is closed (signal 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
• the load in the kitchen in exceptional due to the use of
strong detergents, presence of a large number of people, or
similar.
INTRODUCTION
IMPORTANT
Apartment-specific
ventilation units allows
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.
In order to ensure that
the indoor air presents
no harm to health and
remains optimal also
for the structures of the
building, ventilation
must be kept on
without disruptions.
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.
IMPORTANT
Prolonged overpressure
can result in damage
to the structures of the
building.
At home
Use this ventilation profile when the apartment is
occupied.
Away
Use this ventilation profile when the apartment is
unoccupied, e.g. during a trip or other long absence.
Fireplace profile
Use this ventilation profile e.g. when making a fire in
the fireplace. The profile is primarily used to create
momentary overpressure in the dwelling.
Boost
Use this profile to enhance ventilation, e.g. when
there are more people than usual in the apartment.
Changing the ventilation profile
Vallox 51 MV
The Vallox 51 MV ventilation unit is controlled by using the
MyVallox Control control panel. Press the left button of the
control panel (see the Figure) repeatedly until the desired status
is shown as the middle option on the display.

INSTALLATION
MOUNTING ON THE WALL
NOTE
Avoid mounting the unit on a hollow, echoing partition wall or
on a bedroom wall, or prevent the conduction of sound.
Note that during mounting the unit rises 10 mm higher than
the final height.
Mount the ventilation unit on the wall with a mounting plate, as
shown in the adjacent figure. Make sure that the unit is horizontally
level after mounting.
Vallox 51K MV must be mounted so that the clearance between
the bottom of the cooker hood and the cooker top is at least 426
mm in case of an electric stove and 650 mm in case a gas stove.
The clearance is 134 mm (i.e. the height of the cooker hood) more
between the bottom of the ventilation unit and the cooker top.
EXTERNAL ELECTRICAL CONNECTIONS
External electrical connections are led to the ventilation unit
through the ceiling bushing for electric wires. The length of the
wires must enable pulling the fan chamber assembly out of the unit
without having to disconnect any of the connections.
NOTE
A space of at least 330
mm must be reserved
in front of the unit for
maintenance purposes.
REMOVAL OF CONDENSING WATER
Vallox 51 MV
The Silent Klick water seal is installed in the bottom pool of Vallox 51
MV. The condensing water tube is led from the water seal e.g. to the
water seal of the sink or to the floor drain. Alternatively, an elbow can
be installed in the bottom pool, in which case the Silent Klick water
seal is installed in the condensing water tube to enable maintenance
measures.
NOTE
The Vallox Silent Klick
water seal package is
delivered with Vallox
51 MV and 51K MV.
Installation instructions
for the water seal are
enclosed with the
packaging, and can also
be found online at www.
vallox.com. When the
alternative water seal
installation method is
used, the ring seal and
the locking part must
be moved to the pipe
connection part that is
mounted on the wall.

Vallox 51K MV
In Vallox 51K MV, an elbow is mounted on the bottom pool
between the unit and the cooker hood. Condensing water tube
is led from the elbow e.g. into the water seal of the sink or the
floor drain. The water seal must not be installed inside the cooker
hood. Instead, it must be installed in the condensing water tube
so as to enable maintenance measures. There are approx. 2
mm wide holes at the rear of the bottom of the Vallox 51K MV
ventilation unit marking the position where the condensing water
tube must be installed.
1. Install the elbow at the bottom of the ventilation unit
without the water seal (Figure 1). Install the water seal in
the condensing water tube before the drain or odour trap
(Figure 2). The Silent Klick water seal helps prevent noise
disturbance caused by the removal of condensing water.
2. The condensing water tube must be installed either directly
backwards from the cooker hood through the wall, if there
is a sewer connection behind the wall (see figure 2 for the
dimensions of the tube location), or to the odour trap of the
sink (Figure 2).
3. The condensing water pipe must be placed at an angle so
that it always points downwards.

The accessories delivered with the unit include four (4) air flow
measuring tubes. These can be inserted in the ducts to allow for
easier ventilation adjustment.
MEASURING AND ADJUSTING THE AIR
FLOWS OF THE COOKER HOOD
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.

MV
Air flow measurement points
Air flow measuring tubes are placed in
the ventilation ducts in accordance with
the instructions. Standard air flow from
the cooker hood is measured past the
damper. The fan curves indicate the total
pressure accounted for by duct losses.

BEFORE BEGINNING
MAINTENANCE WORK
WARNING
Always disconnect the power plug before starting
maintenance on the ventilation unit. The unit has no
safety switch that would switch the power o when
the door of the unit is opened.
CHANGING THE FILTERS
The Vallox ventilation unit has three filters:
• Coarse filter for supply air filters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Fine filter for supply air filters microscopic pollen and
dust particles out of the supply air.
• Coarse filter for extract air filters the extract air and
keeps the heat recovery cell clean.
The filter replacement interval depends on the ambient
particle concentration. It is recommended that the filters
be replaced every spring and autumn, or at the very least
once a year.
To replace the filters:
1. Disconnect the ventilation unit from the mains
electricity supply.
2. Open the door of the unit.
CAUTION
The door is heavy.
3. Remove the old filters (A, B, C) and discard them.
4. Install the new filters (A, B, C).
5. Close the door of the unit.
6. Plug the ventilation unit back into the mains.
7. The filters have now been successfully replaced.
TIP
Using original Vallox
filters ensures that the
ventilation unit remains
in top condition, giving
the best results. To
select and order
filter packages,

CLEANING THE HEAT RECOVERY
CELL
Check that the heat recovery cell is clean roughly once a year,
or whenever the filters are being replaced. Clean by washing
as required.
IMPORTANT
If the unit has an enthalpy cell, it must not be washed.
Only aluminium or plastic cells can be washed.
Cleaning the heat recovery cell:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the door of the ventilation unit by undoing the
finger screws and by lifting the door o.
CAUTION
The door is heavy.
3. Pull out the black upper support of the cell (E) located
above the cell.
4. Lift and pull the cell (D) out of the unit.
IMPORTANT
Handle the cell carefully! Do not lift the cell by the
layers. The cell layers are very thin and easily damaged.
5. If the cell is dirty, clean it by immersing it in warm water,
to which a small amount of a mild detergent has been
added.
6. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
7. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
8. Close the door.
9. Plug the ventilation unit back into the mains. The heat
recovery cell has now been cleaned.
MAINTENANCE
CONDENSING WATER
In the heating season, the extract air humidity condenses to
water. In new buildings, condensation runo can form rapidly.
Condensed water must be able to freely leave the unit.
At some time before the heating season begins (e.g. during
autumn maintenance), check that the water seal or the
condensing water outlet in the bottom pool are not clogged. To
check this, pour some water into the pool. Clean as required.
NOTE
Some condensing water
may have accumulated
in the bottom pool
of the unit; this is
normal and requires no
corrective action.
WARNING
Water must at all times
be kept out of the
electrical system.

the ceiling bushing (G) and connected to the connection
card (F) in the electric box prevents moving the fan chamber
suciently far from the ventilation unit, disconnect the
cables. Pull these cables out of the unit through the ceiling
bushing.
5. Detach outdoor and extract air temperature sensors from the
ceiling mounts. Remove the round feedthrough rubbers (H)
from the slots on the intermediate walls of the unit by pulling.
6. Undo the earthing screw (K) on the upper left corner of the
electric box.
7. Release the damper motor (J) by placing an orange magnet
(I) on the magnet icon on the damper motor. Observe the
location of the magnet so that you will be able to return it to
its original location after maintenance. Remove the bar from
the joint of the damper. Turn the crank of the damper motor
so that the bar comes o from the bypass damper and turn
the damper into the cell bypass position.
8. Pull out the upper support of the cell (E). Lift and pull the cell
(D) out of the unit.
9. Pull the fan chamber (K) out of the unit (contains the fans,
electric box, and the bypass duct incl. the damper motor).
10. The fans are mounted on the fan chamber by means of three
screws (L). Do not undo the earthing screw at the bottom
edge on the rear wall side.
11. Disconnect the quick connectors of the fan cable.
12. Clean the fans. The fan can be cleaned with compressed air
(wear protective goggles) or by brushing it gently.
13. To reassemble the ventilation unit, follow the above steps in
reverse order.
NOTE! Remember to reconnect the bar of the damper
motor into the joint of the damper and to lock the
connection with the orange magnet. Ensure that the
sensors and their feedthrough rubbers are in correct
locations. Also ensure that all the connections have been
correctly implemented and the earthing screw is in place in
the left corner.
