SAFETY
Safe and appropriate handling requires knowledge of the basic safety
regulations, and of the intended use of the ventilation system. Read
this manual before operating the ventilation unit. Retain the manual for
later reference. If you lose the manual, it can be downloaded from our
website.
This user manual contains all the information necessary for safe
operation of the system. All persons who operate and maintain
the ventilation system must follow the instructions provided in this
manual. Furthermore, all local accident prevention regulations must be
observed.
Installation
Installation and setup should be carried out only by qualified experts.
Electrical installations and connections must be carried out only by an
electrician and in compliance with local regulations.
GUARANTEE
The guarantee and liability exclude damage resulting from:
• Inappropriate use of the ventilation system or the control unit
• Incorrect or inappropriate installation, setup or use
• Neglect of instructions concerning transportation, installation, use,

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 panel installed in the building.
• Through the MyVallox Home local area network connection
and the MyVallox Home/Cloud user interface.
• Through the MyVallox 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 and carbon dioxide 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.
Connecting the ventilation unit to the cloud
service
The ventilation unit can be connected to the MyVallox Cloud
service. The cloud service allows for controlling ventilation
remotely also, using e.g. a smartphone or tablet. Also the unit
software is updated automatically through the cloud service.
To connect to the cloud service, the ventilation unit must be
connected to the Internet via LAN and registered with the cloud
service. At the same time you create a MyVallox Cloud account
for yourself. Read more about the service at www.myvallox.com.
NOTE
For the MyVallox Cloud/
Home instructions,

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.

INSTALLATION SITE
The Vallox ventilation unit must be installed in a location
where the temperature remains above +10°C. When the unit is
installed without a protective enclosure, the location must be
chosen so that its noise does not cause any disturbance (e.g.
storage premises, technical spaces, and false ceilings).
Vallox TSK Multi 50 MV and Vallox TSK Multi 80 MV must
be mounted on the ceiling. Use the mounting hooks (4 pcs)
delivered with the unit to mount the ventilation unit on the ceiling.
Observe the weight of the unit (45 kg / 58.5 kg) when mounting.
IMPORTANT
The unit must be installed straight so that the
condensing water that collects in the bottom pool drains
through the condensing water outlet.
NOTE
Reserve a space equal to the depth of the unit in front of
the unit for servicing purposes.
The service space in front of Vallox TSK Multi 50 MV
must be at least 530 mm.
The service space in front of Vallox TSK Multi 80 MV
must be at least 600 mm.
NOTE
The whole length of the outdoor air duct to the unit and
exhaust air duct from the unit must be insulated using
closed cell insulation.
REMOVAL OF CONDENSING WATER
The unit is delivered with a siphon that has an air lock and a
more compact elbow. When the elbow is used, an air lock must
be installed somewhere else between the extraction pipes (the
parts needed are included in the accessory bag). The air lock
ensures the removal of condensing water and mues any noise.
MEASURING AND ADJUSTING THE AIR
FLOWS OF THE VENTILATION UNIT
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.

BEFORE BEGINNING MAINTENANCE WORK
The safety switch (S) automatically turns o the power when the door of
the unit is opened.
WARNING
Always disconnect the power plug before starting the ventilation
unit maintenance.
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 side
of the centre line as shown in the instructions. In the left-handed
version, outdoor air blows into the unit from the left side. Also the
position of the filters, HR cell bypass damper, and heating resistor is
mirrored in the left-handed model.
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.
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.

NOTE
Using original Vallox
filters ensures that the
ventilation unit remains
in top condition, giving
the best results. 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 select and
order filter packages,
please go to:
filters.vallox.com

CLEANING THE HEAT RECOVERY CELL
Check that the heat recovery cell (D) is clean roughly once a
year when 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.
To check the heat recovery cell (HR cell):
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Lift the latch to open the door of the ventilation unit.
3. Lift the door o.
CAUTION
The door is heavy.
4. Pull the coarse filters (A, C) and filter supports out of the
unit.
5. Remove the sealing strip (E) above the HR cell.
6. Remove the side sealing strip (F).
7. Remove the fine filter (B).
8. Lift and pull the cell (D) out of the unit.
IMPORTANT
Handle the cell carefully! For example, do not lift the
cell by the layers. The cell layers are very thin and
easily damaged.
9. 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.
10. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
11. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
12. Close the door. Ensure that the safety switch catch of the
door is touching the safety switch.
13. Plug the ventilation unit back into the mains.
14. The heat recovery cell has now been checked and
cleaned.
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 siphon 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.
