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
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.
DISPOSAL OF THE VENTILATION UNIT
Do not dispose of electronic devices with household waste. Follow
local laws and regulations on safe and ecological disposal of the
product.
NOTE

INTRODUCTION
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.

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.

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.
WARNING
Water must at all times
be kept out of the
electrical system.
NOTE
When installing the unit,
reserve a space of at
least 800 mm in front
of the unit for servicing
purposes.
REMOVAL OF CONDENSING WATER
NOTE
The Vallox Silent Klick siphon package is delivered with the
unit. Installation instructions for the siphon are enclosed with
the packaging, and can also be found online at www.vallox.

BEFORE BEGINNING MAINTENANCE
WORK
The safety switch 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.
NOTE
The service space in front of the ventilation unit must be at
least 800 mm.
Opening and closing the doors
1. Turn the latches to open the upper door of the ventilation unit.
2. Lift the upper door o.
CAUTION
The door is heavy.
3. Open the lower door of the ventilation unit by undoing the
finger screws.
4. Lift the lower door o.
5. Close the doors in reverse order.
There are two unit models, left- (L) and right-handed (R). The
figure shows the right-handed model.
CHANGING THE FILTERS
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:
• 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.
NOTE
Using original Vallox filters ensures that the ventilation unit
remains in top condition, giving the best results. To select
and order filter packages, please go to: filters.vallox.com
To replace the filters:
1. Disconnect the ventilation unit from the mains electricity supply.
2. Open the upper door of the unit.
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. Ensure that the safety switch catch
of the door is touching the safety switch, allowing the unit to
be turned on.
6. Plug the ventilation unit back into the mains.
The filters have now been successfully replaced.

CLEANING THE HEAT RECOVERY
CELL
Check that the heat recovery cells are clean roughly once a
year when the filters are being changed. 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 cells:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the doors of the unit.
3. Remove the filters (A, B, C).
4. Remove the support grid of the filters.
5. Disengage the upper support strip (D) of the cell.
6. Lift and pull the cell (E) out of the unit.
7. If the cells are dirty, clean them by immersing it in warm
water, to which a small amount of a mild detergent has
been added.
8. Rinse the cell clean with 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. Close the doors. Ensure that the safety switch catch of the
door is touching the safety switch.
11. Plug the ventilation unit back into the mains.
The heat recovery cells have now been checked and
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 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.

IMPORTANT
Handle the cells
carefully! For example,
do not lift the cells by
the layers. The cell
layers are very thin and
easily damaged.
