5.3 Connecting the ducts
The air inlet can be located in the installation room, in a
different room or outside. In the latter two cases, air inlet ducts
must be installed.
When choosing a room for the air inlet, observe the average air
temperature and required air flow rate (

Tab. 3). In order to
minimise air resistance, lay the air inlet and outlet ducts
(Ø 160 mm) as straight as possible.
The length (L
eq
) of the air inlet and outlet ducts must not
exceed the following values:
• 30 m at fan speed SP1
To ensure that condensate forming in the air inlet and air outlet
ducts drains from the appliance:
▶ Install air ducts horizontally or at a slight angle to the air inlet
and air outlet apertures on the top side of the appliance.
Installation with ducts
▶ Activate “Duct” function (

page 24, chapter 8.6.4).
5.3.1 Open flue operation
If the heat pump is operated with air from the installation
location, the volume of the room must be at least 20 m
3
.
5.3.2 Outdoor air operation
If the pump is operated with outdoor air, the ducts must be
protected against the weather using the correct end pieces.

acoustically insulated ducts.
