Instructions for Use
Important information!
R120.211112
Airflows
The air in the home should be changed at a
continuous and sufficient rate to ensure a pleasant indoor climate and avoid damage to building
elements caused by dampness� The ventilation
unit should be stopped only while service work
is in progress�
The airflow from the ventilation unit can be
controlled to generate the various airflows from
a Premium control panel or a Premium cooker
hood�
• Away = a low airflow, which can be utilized
when no one is in the home and there is no
need for the same ventilation that is normally
in use, e�g� for moisture-removal�
• Home = normal airflow�
• Boost = a high airflow, used in connection
with cooking, taking a sauna bath, showering,
drying laundry and similar activities�
The Away/Home operating modes and the temperature of the supply air can be controlled with
the ventilation unit’s built-in weekly timer; however the operating mode can always be changed
from the Premium control panel or the Premium
cooker hood�
A low airflow when the home is unoccupied
means economical operation� This saves on fan
energy and the home heating system does not
have to heat as much air during the cold season�
The most important function of the ventilation system is to ensure that the indoor
air will be continuously fresh and to remove impurities and moisture from the air.
You should therefore make an appraisal of
whether a low airflow is sufficient while the
home is unoccupied. The low airflow mode
must absolutely not be used when someone
is in the home.
If the load on the home is greater than
you’ve anticipated, then you should increase
the normal airflow to a correspondingly
higher rate.
Drying laundry
A tumbler dryer of extract air type or a drying
cabinet must not be connected to the system
due to the high moisture content in the air leaving them� We recommend a condensing tumbler
dryer without duct connection�
Freeze protection
During periods of cold weather, the heat exchanger is liable to freeze if the extract air is
humid� A protective function then automatically
reduces the speed of the supply air fan� Under
such conditions, variations in the fan speed are
therefore normal�
Filters
The ventilation unit must not be operated without filters� Use only filters recommended by
Swegon in the ventilation unit�
Commissioning
The ventilation should not be commissioned until
all work that produces large quantities of grinding dust or other impurities has been completed�
Swegon reserves the right to alter specifications.

Control from a Premium control panel
When the power is switched on, the ventilation unit
starts up in the Home operating mode� The start time
is approx� 1 minute� After that, the control panel can
be used� Likewise after a power failure, the ventilation
unit starts up in the Home operating mode, if the power
failure has cleared the memory�
The functions of the push buttons are described in the
image to the right�
R120.211112
Fireplace switch function
The speed of the extract air fan decreases and the speed
of the supply air fan increases for a few minutes� This
produces excess pressure in the home and in this way
"creates" an updraught in the chimney, which makes it
easier to light the log-fire�
Selection of fan speed
The fans inside the unit can be controlled to operate at
three speeds: Home/Away/Boost� Select the required fan
speed from the control panel�
You can select an airflow boost time of 30, 60 or 120
minutes, or continuous boosted airflow�
The operating mode can be manually changed, even
when the fan speed is controlled by the weekly timer�
Menu/Installation and service
You can enter settings that affect the operation and
functions of the ventilation unit from the Installation
and service menu and submenu� You should normally
enter these settings when you install the ventilation sys-
tem� The settings are described in Sections 3�5 and 3�6�
Signal lamp
The indicating lamp on the control panel indicates the
functions and alarms of the ventilation unit with various
colours� This is described in Section 5�

Control from a Premium cooker hood
The ventilation unit fan speeds and other settings
should be entered via the Premium control panel� When
you have entered these settings, the functions below
will be available from the cooker hood control panel�
• The cooker hood damper� When preparing food or
carrying out a similar activity, a 30, 60 or 120 minute
damper-open period can be selected� One single
press of the button will change the setting to the
next damper-open period� The fourth press of the
button cancels the setting and closes the damper�
• The cooker hood lighting� On/Off�
• The ventilation unit fan speed� The fans inside the
unit can be controlled to operate at three speeds:
Away/Home/Boost� One single press of the button
will increase the fan speed one step� The period for
the boost speed is preset to 60 minutes, after which
the ventilation unit will return to normal airflow�

The filter should be cleaned every six months and should
be replaced at least once per year� It may be necessary
to clean or replace the filter more often in homes where
there is considerable dust�
Supply air filter
The filter should be cleaned every six months and should
be replaced at least once per year� If the air is highly
polluted, e�g� due to heavy traffic, the filter should be
replaced more often�

1.1 General
You can install the ventilation unit in a scullery, storage space, attic, etc� If the ventilation unit is located
in a cold space, it should be have thermal insulation, if
required�
The ventilation unit conforms to enclosure class IP 44
when the cover is closed�
Connect the extract air from the Premium cooker hood,
if the need arises, via a duct to the extra duct connection spigot on the top side of the ventilation unit�
Otherwise, blank off the connection spigot�
To make it easier to lift the ventilation unit, the inspection cover can be removed and the heat exchanger
can be dismantled from the unit� The fans can also be
removed if necessary� See Section 4, Service�
1.2 To install the ventilation unit
Secure the ventilation unit to the wall using the wall
mounting bracket supplied with the unit�
R120.211112
Horizontal stud for the ventilation unit’s mounting bracket
Acoustic insulation
On delivery, the package containing
the wall mounting bracket is inside the
bypass duct.
The ventilation unit should not be secured to a
wall that borders to a living room or a bedroom.
If the wall is composed of vertical studs and building
boards, the wall must be reinforced with horizontal
studs to enable it to support the weight of the unit�
Swegon also recommends that the wall be insulated
with mineral wool or similar insulation for preventing
sound from propagating to other rooms�
Secure the mounting bracket horizontally to the wall
with screws, using a suitable means of anchoring that
can support the weight of the ventilation unit�
Lift the ventilation unit into place, so that the wall
bracket tips engage into the corresponding slots on the
backside of the ventilation unit�
Make sure that the electric and control cables are
visible. See also Section 1.7 Electric and control
cables.
Wall mounting bracket’s dimensions
Horizontal reinforcement
Wall mounting bracketInsulated wall
The ventilation unit can also be mounted in a mounting
frame on the ceiling� See Optional Equipment�
1.3 Ceiling installation
Fasten the ceiling mounting frame with four M8 threaded rods in the ceiling anchor sleeves so that at least
three of the threaded rods are aligned with the corners
of the ceiling mounting frame� To avoid a possible collision with the ducts, one of the threaded rods can be
located in the hole next to the corner� Screw in the M8
nuts onto the threaded rods to such a height that the
Swegon reserves the right to alter specifications.
The points on the locking hooks on
the edge of the ceiling mounting frame
should be bent back.
The bottom of the ceiling mounting frame
should be positioned approx. 15 mm below the ceiling surface. If ceiling moulding
is fitted around the frame, it should be
mounted after the unit has been installed.
www�swegon�com 7
R120.211112
ceiling mounting frame will be horizontal when the top
of the frame goes against the nuts� Fit the mounting
frame through the selected holes against the nuts on
the threaded rods and lock the frame into position with
nuts from below� The ends of the threaded rods are permitted to stick out max� 3 cm from the ceiling mounting
plate� If they stick out farther, they will protrude against
the unit’s upper casing section�
1.4 Installation in ceiling mounting frame
Run the power supply and data cable through the ceiling mounting frame before you lift the unit into position� Lift the ventilation unit into the ceiling mounting
frame so that all four locking hooks will fit correctly in
the notches at the top of the unit� The locking hooks
have two catches; the lower one locks the unit to
facilitate connection to the ducts and the wiring of the
electric cables� When the unit is at the correct position
in relation to the duct and the electric cables have been
run inside the unit, lift up the upper catches� When
the catches are locked the screws of the upper section
spring out� Finish by ensuring that the ventilation unit is
mounted at its location by tightening the screws in the
upper casing section�
Make sure that no wires
or the like come to rest
between the ventilation
unit and the mounting
bracket.
The R120 lifted up on
the lower catches.
Lock the R120 into
place by tightening
the screws in the front.
1.5 Condensate discharge
As a rule, no condensate discharge is needed under dry
ambient conditions and in combination with a rotary
heat exchanger� A certain amount of humidity load is
common in homes� If substantial moisture is produced
in the home, connect the ventilation unit’s condensate
drain connection to discharge piping�
Connect the condensate discharge hose to the condensate discharge connection of the unit (3/8”, Male
threads)� The condensate must be channelled to a floor
gulley, the water trap of a sink or the equivalent by
means of a stiff hose or a pipe having an inner diameter
of at least 12 mm� The water must not be led away
directly to the sewer�
Vertically mount the water trap on the hose supplied
with the unit and fill it with water� The hose must not
have a second water trap or be run horizontally� The
damming height of the water trap should be at least
100 mm�
Do not use the cooker hood for basic
kitchen ventilation; use it only when you
prepare food.
Condensate discharge
Ø 125 mm
The electric and control cables of the
ventilation unit are located on the top side
of the unit. Make sure that the electric cable can be connected to a wall outlet.

1.6 To connect the cooker hood
Connect a duct from the cooker hood duct connection spigot to the connection spigot on the top side
of the ventilation unit, which is intended for separate
extract air and which conveys the air to bypass the heat
exchanger�
The duct between the cooker hood and the ventilation
unit must be mounted in such a way that makes it possible to clean it�
R120.211112
If the bypass from the kitchen is not used, the outlet
spigot must be blanked off�
1.7 Electric and control cables
The unit has an earthed plug contact for connection to
the mains power� The mains plug serves as the ventilation unit’s main switch and it should be connected to an
electric socket at an easily accessible spot�
The room unit is equipped a 1�5 m long cable with plugin contact, installed from the topside of the ventilation
unit� Arrange the wall outlet at an easy-to-reach location� For power requirement particulars, see Section 7,
Technical data�
Connect the ventilation unit to the Premium control
panel via a modular cable� Install the Premium control
panel at a place of your choice� Two modular cables are
included in the supply: one approx� 3 m long cable and
one 20 m long cable�
When installing the unit, make sure that you provide
adequate access to the connector of each cable (loose
ones as well), e�g� for servicing and adjusting the unit, if
and when the need arises�
The diameter of the modular cable wiring tube should
be 20 mm�
To dismantle the front plate on a Premium control panel.
To connect the modular cable. The extra contact is used for
connection of an extra control panel.
The electric and control cables are
located on the top side of the ventilation
unit. Make sure that the electric cable can
be connected to a wall outlet without obstruction.
The connection of possible optional equipment is
described in the wiring diagram in Section 7, Technical
data� The cables for the optional items of equipment are
not included in the supply�
If you lengthen the modular cable
within some building element (e.g. in a
wall), you should lengthen the cable in a
20 mm dia. conduit, anticipating a possible
later change of cabling.

R120.211112
1.8 Ducts
Install the air ducts, sound attenuators, supply air diffusers, air intake grilles and exhaust air ducts as shown in
the ventilation drawings� To prevent the propagation of
sound, do not install the ducts directly against structural
building elements�
Insulate the air ducts in order to reduce loss of heat or
cooling energy and to prevent water from condensing
on surfaces�
In general, ventilation ducts are insulated in the following manner:
• Outdoor air ducts are insulated in warm spaces and
in attics that are used�
• Exhaust air ducts should always be insulated in accordance with national regulations� See separate project planning instructions (for example Fire resistance
classification requirements)�
• Insulate supply air ducts in cold spaces�
• Insulate extract air ducts in cold spaces�
• If the air inside the duct is colder than the air in the
surroundings, the insulation should be protected by
a moisture barrier (e�g� outdoor air and exhaust air in
interior spaces, or chilled supply air)�
1.9 Moisture barrier against cold timber
frames
It is important that the moisture barrier between cold
stud work and the warm ceiling maintains its tightness
at duct penetration points� A duct penetration piece
(optional extra) will facilitate this�
The thickness of the insulation and
the nature of the surface layer of the ventilation ducts vary depending on insulation
material, climate zone and national standards in force. For this reason, Swegon does
not offer any general recommendations.
Most manufacturers of insulation material
offer calculation programs for the calculation of sufficient and correct insulation.
In renovation projects, it is advisable to
examine the existing ducts to determine
whether they are sufficiently and correctly
insulated.
It is essential that the ventilation
ducts are clean in order for the ventilation
unit to operate as it should. The ventilation ducts should be cleaned regularly
and always when the home is renovated.
10 www�swegon�com
Insulating in the right way is necessary for
the ventilation unit to operate correctly.
When the freeze protection function
is activated, you cannot change the ventilation unit fan speeds from the control
panel.
