▶
Choose the installation site so that the legally required
emissions values for noise outside of buildings can be
complied with, without having to use the heat pump sys-
tem's noise reduction function, if possible.
▶
In certain weather conditions, take into consideration
the possibility of black ice forming directly in front of the
product's outlet side; if condensate escapes, the black
ice may form all around the product.
