SOUND
The noise emission from the heat pumps must be taken
into account in the respective installation plans for air /
water heat pumps. The respective regional regulations
must be complied with.
The following sound pressure levels result, depending on the distance and installation variant with directivity factor Q
(see sketches page 11):

NOTE.
The following sound pressure levels are cal-
culated values. Other constellations, adjoin-
ing other buildings or even reflecting surfaces
may lead to a level increase. An exact specifi-
cation of each sound pressure level is possible
only through a measurement spot when the heat
pump is already installed.
