Important information

Qualified personnel only
Only qualified personnel should carry
out installation, configuration and
commissioning.
Standards and requirements
Applicable national standards and
regulations dealing with installation,
configuration and commissioning must
be followed if the equipment is to
operate correctly.
At the www.swegonhomesolutions.com
address (Resources > Find PDF) you will
find the document "Project planning
instructions for ventilation", in which
power supply, sound, airflows and duct
system requirements are presented.
Measurement and electrical work
If you carry out voltage tests, measure
the electrical insulation resistance at
various points or perform other reme-
dial measures that could damage sensi-
tive electronic equipment, you must
first isolate the ventilation unit from
the electrical supply grid.

Surge protection

Swegon recommends that all ventila-
tion units equipped with Smart auto-
matic control be equipped with a surge
protection device.
Earth fault circuit breaker
It is not certain that an earth fault
circuit breaker will operate faultlessly in
combination with the ventilation unit,
since the unit's regulation and control
equipment can cause leakage currents.
Comply with local electrical safety
regulations when you install electrical
equipment.
To open the ventilation unit for service
EN
Always ensure that the ventilation unit's
power supply has been isolated before
you open the ventilation unit's inspec-
tion door. Wait a few minutes before
you open the inspection door so that
the fans have time to stop and possible
air heaters have time to cool down.

There are no components inside the
electrical equipment cabinet that can
be serviced by the user. The servic-
ing of these components must be
delegated to service personnel. Do
not restart the ventilation unit be-
fore you've identified the cause of
the fault and service personnel have
serviced the ventilation unit.
Separate extract air
(bypass for kitchen)
Keep in mind that the separate
extract air duct runs past the heat
exchanger and that use if it will af-
fect the ventilation unit's annual ef-
ficiency. The separate extract air duct
should only be used while cooking is
in progress and the ordinary extract
air register in the kitchen should be
connected to the ventilation unit's
extract air duct.
The Econo models
(water-heated air heater)
The Econo model ventilation unit
should be equipped with shut-off
damper so that the water-heated air
heater cannot freeze during a power
failure.
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 it
discharges. However, we recommend
the use of a condensing tumbler
dryer without duct connection.
Condensation
The surface temperature of the
ventilation unit can drop down to
approximately 12 °C during periods
of low outdoor temperature and
depending on the moisture content
of the air surrounding the unit, mois-
ture may condense on the surface.
Consequently, condensation should
be taken into account when choosing
furnishings that are to be installed in
the vicinity of the ventilation unit.
