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.

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.
The minimum distance between the top of the unit and the
finished ceiling surface is 30 mm. Note that during mounting
the unit rises 10 mm higher than the final height.
Mount Vallox 096 MV, 110 MV, and Vallox 145 MV on the wall with a
mounting plate, as shown in the adjacent figure. Make sure that the
unit is horizontally level after mounting.
MOUNTING ON THE CEILING
Vallox 096 MV and Vallox 110 MV can be equipped with an optional
ceiling mount plate. To attach the ceiling mounting plate:
• On rafter frames or other frame structure with M8 thread bars so
that they withstand the weight of the unit.

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).
The figure shows the right-handed model.
REPLACING THE FILTERS USER
When the maintenance reminder becomes activated,
check the cleanliness of the filters and replace them if
required.
The Vallox ventilation unit has three air filters:
• Class G4 coarse filter filters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Class F7 fine filter filters microscopic pollen and dust
particles out of the supply air.
• Class G4 coarse filter filters the extract air and keeps
the heat recovery cell clean.
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.
To replace the filters:
1. Disconnect the ventilation unit from the mains
electricity supply.
2. Lift the latch to open the door of the Vallox ventilation
unit.
3. Lift the door off.
CAUTION
The door is heavy.
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.
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.
MAINTENANCE

CLEANING THE HEAT RECOVERY CELL
USER
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.
To check and clean the heat recovery cell:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the Vallox ventilation unit door by first lifting the latch
fully up and then lowering it back a little way.

4. Remove the filters (A, B, C).
5. Remove the sealing strip (E) above the cell in the direction of
the arrow.
6. 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.
7. 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.
8. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
9. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
10. When reassembling Vallox 096 MV, check that the sealing
strip below the cell is pressed against the bottom of the unit.
11. Close the door. Ensure that the safety switch catch of the
door is touching the safety switch.
12. Plug the ventilation unit back into the mains.

MAINTENANCE
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.

16
CLEANING THE FANS INSTALLER
Check the cleanliness of the fans when servicing the filters and
the heat recovery cell. Clean the fans as required.
You can clean the fan blades with compressed air (wear protective
goggles) or by brushing them gently. Do not remove or move the
fan blade balancing weights.
Cleaning the supply air fan
To clean the supply air fan:
1. Disconnect the ventilation unit from the mains electricity
supply.
