INSTALLATION
Set the unit on a stable, solid and level, preferably sound-
insulated surface. Make sure that the foundation is de-
signed for the weight of the heat pump.
ATTENTION
In the air outlet area the air temperature is ca.
5 K below the ambient temperature. Under cer-
tain climatic conditions, therefore, an ice layer
can form in the air outlet area.
Install the heat pump so that the air blower does
not blow in the direction of footpaths.
ATTENTION
Do not tilt the unit more than a maximum of 45°
(in any direction).
NOTICE.
Always observe the installation plan for the re-
spective model. Note the size and minimum
