d) Hook the two wire brackets onto the outside of the duct
adapters using the holes intended for this purpose.

e) Place the ventilation unit in the wire brackets, tilted forward
slightly. There are recesses on the underside of the EPP
housing into which the wire brackets fit exactly. When the
adapters have been fully inserted into one another, you will
hear a distinct click. This means the unit is firmly attached.
ä
Caution!
There is only one way to insert the ventilation unit adapters into
the duct adapters.

3.3. Connecting the condensate drain
ä
Caution!
If the ventilation unit is situated outside the thermal shell of the
dwelling (for example in a non-insulated attic), the condensate
drain must be thermally insulated up to the ventilation unit.
During winter, moisture in the exhaust air from the dwelling may
condense in the heat exchanger. The EPP housing therefore has a
built-in drip tray with two condensate drain ports. With ceiling or
wall mounting, the lower condensate drain port must be connected.
With wall mounting, either condensate drain port can be used.
ä
Caution!
Ensure that the condensate hose is mounted with a downward
slope toward the drain.
ä
Caution!
The condensate hose should not have any sharp kinks in it.
a) Open the condensate drain by pulling on the tab.
