5.4 Connecting air ducts
All air ducts must be installed airtight. The collars on the Ubifl ux Vigor appliance are provided as standard
with sealing rings.
In order to prevent condensation on the outside of the outdoor air supply duct and the air exhaust duct
from the Ubifl ux Vigor appliance, these ducts have to be provided with an external vapor barrier as far
as the appliance. If thermally insulated piping is used here, additional insulation is not necessary.
For compliance with the maximum installation noise level of 30 dB(A), it will have to be assessed for every
installation what measures will be required to limit the noise. In order to optimally dampen the noise of
the fans from and to the dwelling through the duct, at least muffl ers of no less than 1 m are required, but
additional measures may be necessary.
Prevent crosstalk through the air supply and discharge ducts by using separate branches to the diff users.
If necessary, the supply ducts must be insulated, for instance when they are installed outside the insulated
envelope.
The outside air supply should be arranged from the shadowed side of the dwelling, preferably from the
wall or an overhang.
The discharge duct must be fed through the roof boarding in such a way that no condensation forms in
the roof boarding.
The discharge duct between the Ubifl ux Vigor appliance and the roof sleeve should be such that surface
condensation is prevented.
Always use an insulated ventilation roof sleeve.
In order to keep the noise levels down, it is recommended to restrict the external duct pressure to 100
Pa. If the resistance of the duct system is higher than the maximum curve of the ventilator, the maximum
ventilation capacity will be lower.
The air speeds must be limited to a max. of 5 m/s in the main ducts and 3.5 m/s in the branches.
The location of the discharge of the mechanical ventilation air and the sewer stack vent must be chosen
to prevent noise nuisance.
The location of the input valves must be chosen in such a way to prevent fouling and drafts. We recom-
mend using input valves.
When using fl exible muffl ers, account must be taken during the installation that these may need to be
replaced after a period of time.
Install suffi cient overfl ow openings, door gap 2 cm.

5.5 Electrical connections
5.5.1 Connecting the power plug
The appliance can be connected to an easily accessible, earthed wall socket with
the plug that is mounted to the appliance. The electric installation must comply
with the requirements of your power company.
5.5.2 Connecting the multiple switch
The multiple switch (not supplied with the appliance) is connected to the modular connector type RJ12 (connector
X14) that is placed on the rear of the display cap of the appliance ( Exploded view of appliance page 10). For
connection examples of multiple switch ( Connecting position switch page 37).
A wireless remote control ( Connecting wireless remote control (without fi lter indication) page 39) and a combination
of multiple switches is also possible ( Connecting extra multiple switch with fi lter indication page 40).
The 4-way switch can also be used to activate a 30-minutes boost mode by putting the switch to setting 3 for less
than 2 seconds and directly turning it back to setting 1 or 2. The boost mode can be reset by putting the switch to
setting 3 for longer than 2 seconds or by switching it to absence mode (
).
Optional available: demand controlled ventilation 2.0 (clock-controlled or CO2-controlled)
