Set-up and connection

  CAUTION!

In  the  air  outlet  area,  the  air  temperature  is 
approx. 5° K below the ambient temperature. 
Under  certain  climatic  conditions,  an  ice 
layer can therefore form in the air outlet area. 
Install the heat pump such that the air blower 
does not discharge into footpath areas.

  NOTE

Always refer to and follow the installation plan 
for  the  respective  model.  Note  the  size  and 
minimum clearances.
