What the units include can vary depending on the sales area.
Adjustment of supply air temperature and summer/winter
function
The temperature of air coming to the dwelling can be adjusted between circa +10 °C and
+30 °C. The midpoint of the adjustment range is circa +20 °C. When supply air temperature
adjustment has been turned in the OFF position, post-heating is not active. This means that
summer function is activated for the ventilation unit. The unit has a motorised summer/winter
function. When the summer function is on, the heat recovery cell is bypassed as soon as
outdoor air temperature has risen above +14 °C. When outdoor air temperature goes below
+12 °C, the unit starts to recover heat. When supply air temperature adjustment is in the
AUTO position, automatic function is activated for the unit. In this case, the setpoint for post-
heating is +17 °C and the heat recovery cell is bypassed automatically according to outdoor
temperatures as indicated above. When the unit bypasses the heat recovery cell, in which
case summer function is activated, post-heating is off.
Fireplace switch function
It is possible to connect a timer-operated switch to the unit. The switch stops the extract air fan
during the time when the fireplace is heated. NOTE! The starting of the extract air fan may
weaken draught in the fireplace! In winter, this situation may disturb the winter function of the
unit. The situation will normalise in a while, after the fireplace function stops.
Winter function of ventilation unit
A threshold value has been set at the factory for the freezing of the heat recovery cell. When
the threshold is exceeded, the ventilation unit starts to melt the heat recovery cell by guiding
outdoor air flow to bypass the heat recovery cell.
A normal melting period takes from 15 to 45 minutes depending on the extent of ice on
the heat recovery cell and on the amount of extract air flow. The unit has been optimised to
operate on the factory settings in normal operation in dwellings and detached houses. The
winter function parameters can be adjusted for extreme conditions, such as a swimming bath,
but even then it is advisable to contact Vallox Maintenance.
Adjustment of relationship between supply and extract air
This feature may be useful when adjusting air flows at the valves during mounting. After the
valves have been adjusted, a user does not need, and must not, touch the adjustment. When
needed, supply or extract air flow can be reduced at the potentiometer.
When the potentiometer is approximately halfway, supply and extract air flow have not been
reduced. Turning the potentiometer anticlockwise reduces air flow on the supply side, and
turning it clockwise reduces air flow on the extract side.
Maintenance reminder
The unit reminds of the need for maintenance every six months if an indicator (not standard)
has been connected to the connectors of the fault signal relay. The indicator then blinks at
one-second intervals. The maintenance reminder is reset when the door of the ventilation unit
is opened. See the maintenance instructions for information on the necessary maintenance
activities.
Four-step control switch
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 0–11,4 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.

MAINTENANCE INSTRUCTIONS
MAINTENANCE
Before starting maintenance
operations
When you open the VALLOX TSK Multi 50/80
MC 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 MC unit before starting maintenance
operations.
VALLOX TSK Multi 50/80 MC filters 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, out-
door comes from the left side of the unit. The filters, summer/winter damper
and heating radiator also change places correspondingly.
Filters
When the maintenance reminder gives an alarm, the cleanliness of
the filters must be checked. Outdoor air is filtered in the unit with two
kinds of filters. A coarse filter (A) filters off insects, heavy pollen and
other dust. An F7 class fine filter (B) filters off fine dust invisible to the
eye. Extract air is filtered with a coarse filter (C).
By using original Vallox filters you ensure good operation of the
ventilation unit and the best filtering result. The replacement interval
of filters 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 filters, you are also advised to check the
cleanliness of the heat recovery (HR) cell (D) at about two-year
intervals.
The G4 filters 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 filters in place.
T
C A
Detaching of HR cell
Pull the coarse filters and their frames out of the unit. Also remove the fine
filter if it has been used. You can then pull out the sealing ledges situated
on top and on the sides of the HR cell. When the sealing ledges have 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.

Condensing water
During the heating season, humidity of extract air condenses into
condensing water. Water formation may be abundant in new
buildings or if ventilation is low compared to the humidity build-up
caused by the residents.
Condensing water needs to flow out from the ventilation unit without
hindrance. In carrying out maintenance, for instance in autumn
before the beginning of the heating season, make sure that the
condensing water outlet (L) in the bottom tank is not clogged. You
can check it by pouring a little water in the tank. Clean if needed.
Do not let water flow into electrical devices. The unit comes with
a condensing outlet (in the figure) equipped with an airlock and
an outlet without airlock that takes less space. If you use the outlet
without airlock, you have to mount an airlock somewhere between
the discharge pipes (the accessory bag contains the parts needed).
An airlock guarantees the removal of condensing water and
silencing of any sounds.

Fastening
VALLOX TSK Multi 50/80 MC is mounted
normally to a ceiling with four fastening hooks
delivered with the unit. When fastening, take
into account that the unit weighs 45 kg.
Important!
Mount the unit horizontally level to make
sure that the condensing water gathering
in the bottom tank runs into the condensing
outlet.
Condensing water
The delivery includes a water seal. By
connecting a pipe to the water seal the
water condensing from extract air can be
led to a floor drain (not directly to the drain).
The pipe must not rise after the water seal.
For further instructions on the mounting of
the water seal and outlet, see the accessory
bag.
