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

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 the ventilation unit onto the wall with a mounting plate
(optional), as shown in the figures below. 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.
• Ensure that the installation plate is horizontally level, as this
determines the position of the unit.
• The top edge of the white covering strip of the ceiling mounting
plate can be installed against the ceiling. Alternatively, a
concealed mounting method can be used, in which case the
ceiling can be 20mm below the top of the white covering strip.
Insulate the ducts against condensation also between the unit and
the ceiling mounting plate.
Mounting the ceiling mounting plate
1. Fasten the thread bars on the rafter frames or other frame
structure, and screw the nuts onto the bars.
2. Lift the ceiling mounting plate in place.
3. Push a rubber damper and a washer onto each thread bar, and ensure
that they touch the bottom of the cups of the plate (Vallox 096 MV).
4. Turn the nuts to make sure that the unit is horizontally level.
5. Shorten the lower ends of the thread bars so that they will be at no
more than 10 mm from the lower surface of the ceiling mounting plate.
CAUTION
The ventilation unit is very heavy. Do not perform this
procedure alone.

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.
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.
3. Lift the door o.
CAUTION
The door is heavy.
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.
The heat recovery cell has 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.

CLEANING THE FANS
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.
2. Lift the latch to open the door of the Vallox ventilation unit.
3. Lift the door o.
CAUTION
The door is heavy.
4. Remove the extract air filter (C), the cell top bracket (E) and the
heat recovery cell (D). See chapters “Replacing the filters” and
“Cleaning the heat recovery cell”.
5. Pull out the temperature sensor (figure 1) located at the top
of the extract air duct (G). Remove the stopper screw (I) at the
bottom of the duct. The extract air duct now comes out by
turning and pushing it downwards simultaneously (figure 2).
6. Remove the temperature sensor from the resistor support
(figure 4).
7. Remove the additional and post-heating resistor support,
which is attached by two wing nuts (Vallox 110 MV and Vallox
145 MV) or screws (Vallox 096 MV) from below (figure 5).
MAINTENANCE
IMPORTANT
The fans are
extremely sensitive
to external shocks. It
is recommended that
the fans be cleaned
in place, i.e. without
attempting to remove
them.
Handle the fan blades
carefully. Do not
remove or move the
fan blade balancing
weights.

8. Pull the radiator and the support out of the unit (figures
6 and 7) and remove the quick connector of the radiator
wires.
CAUTION
Before removing the resistor from the unit, make
sure it is not hot.
9. The fan can now be cleaned in place. It is
recommended that the fan be cleaned in place, i.e.
without attempting to remove it.
10. To remove the fan for cleaning:
a. If necessary, remove the arm pins. Use pliers to
press the pins straight, so that they are easier to
install back later.
b. Push the fan gently upward (figure 9).
c. Pry the plastic lock to the right of the fan with a
screwdriver, for example (figure 10).
d. The fan falls downwards.
e. Pull the fan out of the unit (figure 11).
f. Disconnect the fan wire quick connector (figure 12).
The fan has now been removed for cleaning.
11. To reassemble the ventilation unit, follow the above
steps in reverse order.
TIP
When you re-install the temperature sensor,
position it with the tip upward and pointing at the
wall in such a way that it does not get squeezed
between the HR cell bypass damper or lean against
the radiator frame.
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.
The fan has now been checked and cleaned.
