Extract air fl ow
potentiometer in
electrical box
Reduction of extract air fl ow
When the potentiometer is as shown in the
fi gure, extract air fl ow has not been slowed
down at all. Factory setting.
OPERATING INSTRUCTIONS
Fan speed adjustment
The fan speed of a Vallox ventilation unit can be controlled with a control switch (option), with
a separate cooker hood (option) or directly with a 0-10 V voltage signal.
Speeds 1, 2, 3 and 4 can be selected at the control switch.
1. Operation during absence. When the dwelling is empty, ventilation can be reduced
temporarily.
2–3. Normal operation. In normal operation, air has to be replaced once every two hours.
4. Boosted operation. Cooking, taking a sauna bath, washing, drying clothes, using the
toilet, having guests or a corresponding situation may cause a need for higher ventilation than in normal operation.
Four-step control switch
Cooker hood PTXPA-MC
Heat recovery bypass
In winter use the heat recovery cell of VALLOX TSK Multi SC BP 50/80 recovers heat from the
air leaving the dwelling and uses it to heat the air coming from the outside.
In summer use when it is warm outside, heating of outdoor air is not needed. The heat
recovery cell is then bypassed with the damper in VALLOX TSK Multi 50/80 (see page 1,
item 9).
The damper is controlled by a separate 0–1 switch (not included in the unit delivery). The
switch is mounted in the dwelling at the same time as the electrical installation. In the summer
position, air fl ow through the cell is prevented and heat recovery bypass is opened.
Air fi ltering
Vallox TSK Multi 50/80 has coarse fi ltering of both extract and supply air before the fans.
There is a G4-class coarse fi lter (see page 1, item 7) on the supply air side and a G4-class
coarse fi lter (see page 1, item 8) on the extract air side. The unit can also be equipped with
a F7 fi ne fi lter (see page 1, item 6), which captures fi ne dust and pollen as well as dust not
seen to the eye. The fi lters must be in place in the unit whenever ventilation is in operation.
Antifreeze
Water condensing from extract air may freeze in the heat recovery cell. Antifreeze is
implemented in the unit either by stopping the supply air fan or with a preheating radiator,
depending on how the unit is equipped.,
When the potentiometer is as shown in the
fi gure, the reduction of extract air fl ow is at
its highest.
Outdoor air preheating
In units equipped with a preheating radiator (see page 1, item 4) an antifreeze thermostat
(see page 1, item 3) switches the preheating radiator on when extract air temperature after
the cell goes below +5 °C. The preheating radiator switches off when temperature has risen
by circa three degrees to +8 °C. The preheating radiator heats outdoor air before the heat
recovery cell and prevents it from freezing. In very cold temperatures, the preheating radiator
is not enough to heat maximum air fl ow to a suffi cient degree (in a temperature of -30 °C
maximum air fl ow is 30 dm3/s). The limit of the thermostat can be adjusted.
Reduction of extract air fl ow
Extract air fl ow can be reduced at the potentiometer located in the electrical box. This feature
can be useful when the ventilation system is adjusted. In other situations, the potentiometer
and its position must not be touched. After the adjustment, mark the position on the body of
the potentiometer with for instance a marker pen, as has been done in the fi gure below. This
After a possible adjustment has been made,
mark a line on the potentiometer with for
instance a marker pen, as shown in the fi gure. This makes it possible to turn it back to the
suitable position if it has changed for some
reason.
This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack
of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand
Cleaning and user maintenance shall not be made by children without supervision.

MAINTENANCE INSTRUCTIONS
MAINTENANCE
Before starting
maintenance operations
When you open the VALLOX TSK
Multi 50/80 SC BP unit, the safety
switch of the door (T) turns power
off from the unit. In spite of that,
always disconnect the plug of the
VALLOX TSK Multi 50/80 SC BP
unit before starting maintenance
operations.

VALLOX TSK Multi 50/80 SC BP fi lters and heat recovery cell
The units are available as right- and left-handed models. In a right-handed
(model R) model, outdoor air comes to the unit from the right side of the
centre line, as shown in the instructions. In a left-handed (model L) unit, outdoor comes from the left side of the unit. The fi lters, summer/winter damper
and heating radiator change places correspondingly.
Filters
When the maintenance reminder gives an alarm, the cleanliness of
the fi lters must be checked.
Outdoor air is fi ltered in the unit with two kinds of fi lters. A coarse
fi lter (A) fi lters off insects, heavy pollen and other dust. An F7 class
fi ne fi lter (B) fi lters off fi ne dust invisible to the eye. Extract air is fi ltered
with a coarse fi lter (C).
By using original Vallox fi lters you ensure good operation of the
ventilation unit and the best fi ltering result. The replacement interval
of fi lters depends on dust content in ambient air. It is recommended to
replace fans in spring and autumn, but at least once a year.
Heat recovery cell
When you replace the fi lters, you are also advised to check the
cleanliness of the heat recovery (HR) cell (D) at about two-year
intervals.
The G4 fi lters and their supports, the sealing ledge (E) above the HR
cell and the side sealing ledge (F) must be pulled off before the cell
can be detached. When the sealing ledge has been removed, the
HR cell can be pulled out of the unit.
Note! The laminas of the HR cell are very thin and get easily
damaged.
The correct way to remove the HR cell is to put your hands behind
the HR cell and slowly pull it off. If the HR cell is dirty, wash it by
immersing it in a solution of water with washing-up liquid. Rinse the
HR cell clean with a jet of water. When water has drained from
between the laminas, you can push the HR cell back in place.
Finally, push the sealing ledges and fi lters in place.

Fans
Check the cleanliness of the fans when carrying out maintenance
for a fi lter and the heat recovery cell. Clean the fans if needed. The
fans can be removed from the unit for cleaning. The fan blades can
be cleaned with compressed air or with a brush. Do not remove or
move the balancing pieces on the fan blade.
