USING THE UNIT
The fan speed of the Vallox ventilation unit is adjusted
using a four-step control.
The available speed options of the control switch
are 1, 2, 3, and 4:
1. Away mode. The ventilation eciency can be
temporarily reduced when the apartment is
unoccupied.
2-3. Standard mode. In standard mode, the air inside the
apartment is replaced once every two hours.
4. Boost mode. Cooking, sauna, bathing, drying of
clothes, guests, and other similar situations can
require that ventilation be increased from the
standard setting.
The fan speed can also be controlled through a separate
Vallox control hood, the Vallox ProControl control panel,
or directly through voltage messages (0-10 V).
Vallox Simple Control control
panel
The temperature of the air blown into the apartment can
be adjusted approximately between +10°C and +30°C.
The unit has an automatic summer/winter function
(a bypass flap).
• When the adjusted temperature is between +10°C
and +30°C, the heat recovery cell is not bypassed,
i.e. the unit is in winter mode.
• In the OFF position, the unit is in the summer mode,
i.e. post-heating is turned o and the heat recovery
cell is bypassed when the outdoor temperature is
above +14°C. The heat recovery will be turned on
when the outdoor temperature falls below +12°C.
• In the AUTO position, the unit will operate as follows
around the year: The default post-heating setting
is +17°C. The unit will bypass the heat recovery cell
when the temperature of the outdoor air exceeds
+14°C. The heat recovery will be turned on when the
outdoor temperature falls below +12°C. During the
bypass, post-heating is turned o.

FAN SPEED ADJUSTMENT
ADJUSTING THE SUPPLY AIR TEMPERATURE
AND SUMMER/WINTER FUNCTION
The winter function of
the ventilation unit
The limit value has been set in the factory for freezing of
the heat recovery cell. When this limit value is exceeded,
the ventilation unit starts to defrost the heat recovery cell
by directing the outdoor air past the heat recovery cell.
The duration of the defrost cycle is 15-45 min depending
on the amount of ice accumulated in the heat recovery cell
and on the extract air flow. The factory settings ensure
optimal operation in standard living and detached house
conditions. Even though the winter operation parameters
can be adjusted for certain extreme conditions, such as
swimming pool facilities, it is always advisable to contact
Vallox maintenance services.

USING THE UNIT
FIREPLACE SWITCH
A switch with timer functions can be connected to the unit. The switch stops the
extract air fan when the fireplace is being used. NOTE! Starting up the extract
air fan can reduce the draw of the fireplace! In winter, this can disturb the winter
mode of the ventilation unit. The situation will return to normal soon after the
fireplace mode is turned o.
ADJUSTING THE SUPPLY AND EXTRACT AIR
RATIO
This function might be needed when the air flows are adjusted at the valves
during installation. The user does not need to adjust this function once
the valves have been adjusted, and indeed should not adjust it at all. A
potentiometer can be used to reduce the supply or extract air flow as required.
When the potentiometer is set roughly in the centre position, neither the supply
nor the extract air flow has been reduced. When the potentiometer is turned
anti-clockwise, the supply air flow is reduced, and when the potentiometer is
turned clockwise, the extract air flow is reduced.

TROUBLESHOOTING TABLE
If the ventilation unit is aected by any of the errors listed in the table, the unit will report the error through the error relay,
signal light, and circuit board LEDS. The number of flashes indicates the nature of the error.
The error relay can be connected to remote monitoring.
NOTE! When remote monitoring is used, the signal light of the control panel cannot be turned on.
MAINTENANCE REMINDER
If a signal light is connected to the connectors of the unit’s error relay, the unit will send a reminder of service need every
six months,. If connected, the signal light will flash every second. Sounds made by the relay can then be heard from
inside the unit. The maintenance reminder will be set o automatically when the door of the ventilation unit is opened or
the power is turned o. The maintenance reminder can also be set o manually.
The Vallox Simple Control control panel, and the
Vallox X-Line PTXP MC and PTXPA MC control
hoods, VAK 0-10 VDC:
• The low speed is turned on, then higher-lower-higher
- Low speed under 4 V
- High speed over 6 V
- The selected speed will always be turned
on for 1-5 seconds
Vallox Capto PTC EC control hood:
• The damper is closed, then open-closed-open
• Press at a 1-5 second interval.
The service reminder will only be set o if it has been activated. Refer to the maintenance instructions for the necessary
maintenance measures.

MAINTENANCE
The R model is shown in the figures.
In the L model, the parts are mirrored.
BEFORE BEGINNING
MAINTENANCE WORK
When you open the door of Vallox 101 MC, the safety
switch (S) cuts the power. Despite this, disconnect the
power supply plug anyway. Always disconnect the power
plug before starting maintenance on the Vallox 101 MC.
FILTERS
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 (A) filters insects, heavy pollen
and other relatively large foreign objects out of the
outdoor air.
• Class F7 fine filter (B) filters microscopic pollen and
dust particles out of the supply air.
• Class G4 coarse filter (C) filters the extract air and
keeps the heat recovery cell clean.
Using original Vallox filters ensures the best operation
of the ventilation unit and the best filtering 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.
HEAT RECOVERY CELL
Check that the heat recovery cell (D) is clean roughly
once a year when the filters are being replaced. Clean by
washing as required.
• Remove the sealing strip (E) above the heat recovery
cell in the direction of the arrow. Also remove the
extract air filter (C).
• Lift the heat recovery cell and pull it 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.
If the heat recovery cell is dirty, clean it by immersing it in
water containing a small amount of a mild detergent. Rinse
the heat recovery cell clean with a water spray. When all
the water has drained from between the layers, the heat
recovery cell can be installed.
• Ensure that the lower support (F) is in place between
the knobs at the bottom of the unit before the heat
recovery cell is installed.
• Push the heat recovery cell in place. Also push the
sealing strip (E) in place so that the strip is supported
by the corner bracket (G) at the rear. Lastly, install the
extract air filter (C) in place.

MAINTENANCE
FANS
Check the cleanliness of the fans when servicing the filters
and the heat recovery cell. Clean the fans as required.
The fans are very sensitive to external impacts, and it is
recommended that they be cleaned in place rather than
removing them.
You can clean the fan blades with compressed air or by
brushing them gently. Do not remove or move the fan
blade balancing weights.
Cleaning the fans
• Remove the extract air filter (C), the sealing strip (E),
and the heat recovery cell (D) from the unit following
the instructions provided earlier. The fans can now
be cleaned. The control grille in the suction outlet of
the supply air fan (T) can be removed if it is in the way
during cleaning. To remove the grille, the supply air
fan must first be removed from the unit.
• To remove the fan, disconnect the quick connector
(H) of the supply air fan (T) and/or the extract air fan
(P) cables.
• Push the fan cables and the rubber feed through (I)
into the fan chamber.
• Remove the wing screws used to fasten the fans (J)
(3 screws per fan).
• Remove the fan from the unit by pulling it forward and
by tilting it slightly backwards at the same time.
Removing and mounting the supply air fan
attenuation grid
• Remove the mounting screws (4) of the air flow
control grille of the supply air fan and remove the
grille. You can now clean the fan. Put the control grille
back in place after cleaning.
Mounting the fans
• Ensure that the rubber feed throughs set in place
when reinstalling the fan. Fasten the fan in place with
wing screws (3 screws/fan).

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
condensing water outlets in the bottom pool are not
clogged. To check this, pour some water into the pool.
Clean as required. Water must at all times be kept out of
the electrical system.
See the condensing water connections on page 15.

Vallox 101 MC 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. Such locations include storage premises and
technical spaces.
NOTE!
Remember to make a service door in the finished ceiling
so that the connection cables can be accessed. The
service door should be located roughly 500mm from the
unit door.

The top surface of the side panel of the unit can
be installed against the finished ceiling surface.
When the wall mounting plate is used, it must be
observed that the ventilation unit will rise roughly
10mm above the final installation height!
The outer diameter
of the duct is 12mm
Wall mounting
Mount the Vallox 101 MC on the wall with a mounting plate,
as shown in the adjacent figure. Make sure that the unit is
horizontally level after mounting.
Wall structure
The wall structure must be observed in the mounting.
Avoid mounting the unit on hollow, echoing intermediate
walls and on bedroom walls, or take measures to prevent
conduction of noise.

INSTALLATION
Ceiling mounting by using
a ceiling mounting plate
(optional)
The unit can be equipped with an optional ceiling
mounting plate. The ceiling mounting plate must be
fastened on rafter frames or other frame structure with
M8 thread bars. The bars must be fastened so that they
withstand the weight of the unit.
The ceiling mounting plate must be fastened horizontally
to make sure that the unit is level. The ceiling mounting
plate must be fastened so that there is a 10 mm gap
between its rear edge and the finished wall. This way
the ventilation unit will be installed as close to the wall as
possible. The top edge of the white covering strip of the
ceiling mounting plate can be installed against the finished
ceiling. Alternatively, a concealed mounting method can
be used, in which case the finished ceiling can be 30mm
or less from the top edge of the white covering strip.
The ceiling mounting plate is fastened to the M8 thread
bars with the mounting supplies delivered with the
mounting plate. NOTE! The end of the thread bars must
be 5mm or less below the fastening nut (more detailed
instructions are provided with the ceiling mounting plate).
Installing the ventilation unit to the ceiling
mounting plate
Remove the unit door. Lift the unit and take the wires
through the opening in the ceiling mounting plate. Lift
the ventilation unit against the ceiling mounting plate so
that it locks in place. The unit has become locked on the
ceiling mounting plate when the two operating levers on
the mounting plate have been restored to the same level
with the white covering strip of the ceiling mounting plate
(more detailed instructions are provided with the ceiling
mounting plate).
Ceiling mounting plate (optional)
The top edge of the white covering strip of the ceiling mounting plate can be installed against the finished ceiling. Alternatively,
a concealed mounting method can be used, in which case the finished ceiling can be 30mm or less from the top edge of the
white covering strip.
The minimum distance from
the finished rear wall is 10mm
The recommended distance from
the finished side wall is 10mm

INSTALLATION
The delivery includes the Vallox Silent Klick water seal.
A pipe will be connected to the water seal that leads the
water that is condensed from the extract air to the floor
drain (not directly into the sewer). The pipe must not rise
after the water seal. The ventilation unit must be installed
straight to ensure that condensing water can exit the unit
unobstructed.

water seal can be installed on the wall. This installation
method requires that there is a 47mm space underneath
the unit. The elbow requires a 38mm space when
installed.
