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,
or maintenance
• Structural or electronic modifications or changes made to the
software
INTENDED USE
All Vallox ventilation units have been designed to provide appropriate
and continuous ventilation so as to present no threat to health and to
maintain structures in good condition.
IMPORTANT
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

VENTILATION UNIT CONTROL
Connecting the ventilation unit to the cloud
service
The ventilation unit can be connected to the MyVallox Cloud
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.
Ventilation unit control options.
Operation of the Vallox ventilation unit can be controlled by the
following means:
• Through the 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 using the optional carbon dioxide
and humidity sensors. 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.

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.
MEASURING TUBES
The accessories delivered with the unit include four (4)
airflow measuring tubes. These can be inserted in the ducts
to allow for easier ventilation adjustment.

CONDENSING WATER
The unit is delivered with a water seal 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.
WARNING
Water must at all times
be kept out of the
electrical system.

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, bypass flap, and heating resistor is mirrored in
the left-handed model.
REPLACING THE FILTERS (USER)
When the maintenance reminder becomes activated, check the
cleanliness of the filters and replace them if required. The ventilation
unit has three air 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.
3. Lift the door o.
4. Remove the old filters (A, B, C) and discard them.
5. Install the new filters (A, B, C).
6. Close the door of the unit. Ensure that the safety switch catch
of the door is touching the safety switch, allowing the unit to be
turned on.
7. Plug the ventilation unit back into the mains.
8. The filters have now been successfully replaced.

B
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 dust
concentration. It is
recommended that the
filters be replaced every
spring and autumn, or
at the very least once a
year.
MAINTENANCE
NOTE
Vallox TSK Multi 50 MV:
The service space in
front of the unit must be
at least 530 mm.
Vallox TSK Multi 80 MV:
The service space in
front of the unit must be
at least 600 mm.

CLEANING THE HEAT RECOVERY
CELL (USER)
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
Handle the cell carefully! For example, do not lift the
cell by the layers. The cell layers are very thin and
easily damaged.
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.
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.
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.
IMPORTANT
If the unit has an enthalpy cell, it must not be washed.
Only aluminium or plastic cells can be washed.
CONDENSING WATER (USER)
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.
