Requirements of the installation location
Note
The unit may only be installed in areas
where temperatures below –10 °C only
ever occur briefly during the course of
the year.
We recommend that the unit is not
installed in locations higher than 1000 m
above sea level. Otherwise a drop in per-
formance is to be expected.
■ To prevent an increase in sound emis-
sions through reflection, avoid instal-
ling the external unit in recesses,
quoins or between walls.
Never position the external unit next to
bedrooms.
■ Location with good air circulation.
■ Freestanding on a solid substructure
to be provided on site with a minimum
height of 100 mm to enable the con-
nection of the condensate line.
For installation in difficult climatic sur-
roundings (minus temperatures,
snow, humidity), we recommend the
installation of the unit on a plinth of
approx. 200 mm height.
