▶ Do not tilt the appliance on his feet more
than 20°.

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.
To ensure maximum appliance performance
and to prevent condensation forming on the
external duct walls, use thermally and
acoustically insulated ducts.
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 ) of the air inlet and outlet ducts must not
eq
exceed the following values:
• 30 m at fan speed SP1
0.5 m duct
1 m duct
2 m duct
10 m hose
45° elbow
90° elbow
90° flexible curve
Weather grille
Roof output
Table 4
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

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.
