[2] Connection module with built-in adapter panel
[3] 90° bend
[4] BORA Ecotube shallow, vertical 90° bend EFBV90
[5] BORA shallow silencer USDF

[7] BORA Ecotube shallow duct (optional)
[8] BORA Ecotube shallow, round, offset transition piece EFRV
[9] BORA plinth fan ULS
i
The installation height can be extended between the
Ecotube shallow, round, offset transition piece EFRV
[8] and the shallow silencer USDF [5]. This requires the
Ecotube shallow duct connection EFV [6] and a length-
adjusted Ecotube shallow duct [7].
XX
Ensure that suitable BORA Ecotube seals have been attached
to all connections and that they are airtight.
XX
Attach the 90° bend [3] to the connection module with a built-
in adapter panel [2].
XX
Position the plinth fan ULS [9].
XO
To facilitate positioning, the inlet nozzle on the plinth fan can be
removed. To do this, please see the assembly instructions for
the BORA plinth fan.
XX
Connect the plinth fan ULS [9] to the Ecotube shallow, round,
offset transition piece EFRV [8].
XX
Connect the Ecotube shallow, round, offset transition piece
EFRV [8] to the shallow silencer USDF [5].
XX
Connect the shallow silencer USDF [5] to the BORA Ecotube
shallow, vertical 90° bend EFBV90 [4].
XX
Connect the BORA Ecotube shallow, vertical 90° bend
EFBV90 [4] to the 90° bend [3].
XX
Secure the shallow silencer using the mounting brackets
included.
XO
Securing the shallow silencer prevents forces from being
applied to the cooktop extractor and the duct system.

XX
Pull the seal [2] onto the duct part/component without a
sleeve [1]. To do this, the seal [2] will need to be stretched
slightly.
XX
Push the connecting duct part/component with a sleeve [3]
onto the duct part with the seal.
XX
Ensure that the seal [2] is not displaced.
