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 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 101 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
30 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 (E) onto the bars.
2. Lift the ceiling mounting plate in place.
3. Push a rubber damper (F) and a washer (G) to each thread bar.
4. Adjust the nuts so that the ceiling mounting plate is level.
5. Shorten the lower ends of the thread bars so that they are no more
than 5 mm below the nuts.
CAUTION
The ventilation unit is very heavy. Do not perform this
procedure alone.

The end of the thread bars must be 5 mm or less below
the fastening nut. Do not fasten the ceiling mounting plate
too tight to the ceiling. Ensure that the sliding bars move
and restore to their original position by pulling from the
operating levers (A).
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.
2. Ensure that the insulation washers are in the outlet collars
below the ceiling mounting plate.
3. Remove the door before installing the ventilation unit to the
ceiling mounting plate.
4. Lift the ventilation unit close to the ceiling mounting plate and
feed the cables and the connection box through the hole in
the ceiling mounting plate on top of the ceiling.
NOTE
Remember to make a service door in the ceiling so that
the cables and the connection box can be accessed.
The distance between the service door and the ceiling
mounting plate must be around 500 mm.
Alternatively, the cables can be fed between the ceiling
mounting plate and the ventilation unit to the rear wall. When the
ventilation unit is lifted against the ceiling mounting plate, the
unit locks in place. Where needed, guide the mounting hooks on
the ceiling mounting plate (B) to the grooves on the side panels
of the ventilation unit.
There are operating levers (A) on the front bottom corners of the
ceiling mounting plate. When the levers have been restored to the
same level with the white covering strip of the ceiling mounting
plate, the unit has been locked in place.
5. Where required, the unit can be detached from the ceiling mounting
plate. Remove the door of the unit. Lift the unit slightly upwards and
pull simultaneously from both operating levers (A) of the ceiling
mounting plate to detach the unit from the ceiling mounting plate.
Attic floor penetration plate
The attic floor penetration plate (D) is optional. When an attic floor
penetration plate is used, the tightness of the vapour barrier has
to be ensured.
The attic floor penetration plate can be fastened on the finished
rear wall. The minimum distance of the attic floor penetration plate
from the finished side walls is 15 mm.

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. Open door of the Vallox ventilation unit by undoing
the finger screws.
3. Lift the door off.
4. Remove the old filters (A, B, C) and discard them.
CAUTION
The door is heavy.
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.

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 door of the Vallox ventilation unit by undoing the
finger screws.
3. Lift the door off.
CAUTION
The door is heavy.
4. Remove the sealing strip (E) above the HR cell in the
direction of the arrow.
5. Remove the extract air filter (C).
6. Lift and pull the HR cell (D) out of the unit.
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 as follows:
10. Ensure that the lower support (F) is in place between the
knobs at the bottom of the unit.
11. Push the heat recovery cell in place.
12. Push the sealing strip (E) in place so that the strip is
supported by the corner bracket (G) at the rear.
13. Install the extract air filter (C) in place.
14. Close the door. Ensure that the safety switch catch of the
door is touching the safety switch.
15. Plug the ventilation unit back into the mains.
The heat recovery cell has now been checked and
cleaned.
MAINTENANCE
IMPORTANT
If the unit has an
enthalpy cell, it must
not be washed. Only
aluminium or plastic
cells can be washed.
IMPORTANT
Handle the cell
carefully! For example,
do not lift the cell by the
layers. The cell layers
are very thin and easily
damaged.
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.

Operation and sample connection
Always follow first and foremost the connection
diagram provided by the HVAC designer or heat pump
manufacturer. Also read the duct radiator manual.
Enclosed is an example of connecting the duct radiator to
the heat collection circuit.
Connect the duct radiator output pipe to the heat collection
circuit return pipe. The fluid returning from the duct radiator
is directed back to the heat collection circuit return pipe.
If the pressure loss inside the heat collection circuit of the
heat pump is known to be high, it is recommended that the
heat pump be bypassed. When this happens the pressure
loss in the one-way bypass valve Y2 must be lower than the
pressure loss in the heat pump.
If the duct radiator is used both for preheating and cooling,
it must be installed in the outdoor air duct before the
ventilation unit. In this case, the pump and the solenoid
valve can be controlled using a Vallox MV ventilation unit,
and no separate thermostats are needed.
NOTE: HEATING
The pump starts
when the outdoor air
temperature drops
below the winter limit
value set at the factory
(-5 °C).
NOTE: COOLING
The value set for the
supply air temperature
of the active profile (e.g.
At home) controls the
startup of the pump.
The pump starts when
the supply air setting is
below the temperature
of the supply air that
is blown into the
apartment.
NOTE
When selecting the
relay (C), take account
of the maximum
allowed combined
power supply (6W) of
the circuit board in the
external MV electrical
box, if the relay power
supply comes from the
circuit board’s +24V
connector.
P
Circulation pump. Not included in the delivery.
The pump must be compatible with the
fluid used in the heat collection circuit, and
its capacity must be correct (for example,
Grundfoss Magna 1 25-80).
V
Solenoid valve. Not included in the delivery. The
valve that is chosen must be compatible with the
heat collection circuit fluid (for example, Danfoss
032U157131, HVAC code 4122106).
KCondensing water tube. Not included in the
delivery.
LSupply air thermometer. Not included in the
delivery.
IP De-aerator. Not included in the delivery.
S External electrical box for the MV.
C
24 VDC relay/contactor for controlling the pump
and the solenoid valve. Not included in the
delivery. (For example, ABB CR-P024DC2)
YOne-way valve. Not included in the delivery.
Y2
One-way valve. Not included in the delivery. The
pressure loss must be less than the pressure
loss of the heat pump.
