Important information!

Airflows
The air in the home should be changed at a
continuous and sufficient rate to ensure a pleas-
ant 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 used
when no one is present in the home�
• Home = normal airflow�
• Boost = a high airflow, used in connection
with cooking, taking a sauna bath, showering,
drying laundry and similar activities�
On the models with electric reheating, the
Away/Home operating modes and the supply air
temperature can be controlled with the ventila-
tion unit's built-in weekly timer; however the op-
erating 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 ventila-
tion 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.
Swegon reserves the right to alter specifications.
To ensure that the ventilation unit is used in
the right way, you should equip the system
with a humidity sensor, if you have begun
using the Away mode.
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 leav-
ing them� We recommend a condensing tumbler
dryer without duct connection�
Freeze protection
During periods of cold weather, the heat ex-
changer 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 with-
out filters� Use only filters recommended by
Swegon in the ventilation unit�
Commissioning
The settings of the airflows for the Home, Away
and Boost modes should be entered according to
the instructions so that the ventilation unit will
operate correctly� The ventilation should not be
commissioned until all work that produces large
quantities of grinding dust or other impurities
has been completed�
