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.

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.
S
C
A
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.

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
032U161431, HVAC code 4122110).
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.
C24 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.
