4 Preparation
4.1 Noise emission
The appliance is louder on its air-inlet and air-outlet
sides than on both closed sides. Take the following
pointers into consideration when selecting the place of
installation:
► Installation on beamed roofs is not permitted.
► Do not place the appliance directly under or beside
living or bedrooms.
►
Make sure that the air inlet and outlet openings in
the outside walls are not pointed at living room or
bedroom adjacent windows.
► We recommend placing the heat pump on suitable
rubber matting in the event of reverberating bases
such as tiling.
► A more suitable noise reduction can be achieved
with a concrete foundation plate with rubber mat-
ting.
► Pipework conduits through walls and ceilings must
be noise insulated.
► Our heat pumps are distinguished by their especial-
ly quiet operation. Incorrect integration by the instal-
lation can, however, lead to undesired increase in
the sound level under unfavourable circumstances.
NOTE:
You can find information on the sound
power level in the "Technical Data / Data
Table" section.
4.2 Air ducting
► Short circuiting between air inlet and outlet must be
avoided in all events.
► It is practical to construct the ducting across a cor-
ner.
► If necessary, a separating wall or suitable plants
should be placed between air inlet and outlet.
► The weather and/or bird protection grilles should be
easily removed for cleaning.
► The hose length on the suction and exhaust sides
must not exceed 8m. Do not make more than four
90° bends. The bending radius must be at least
600mm, based on the hose middle.
► Due to its flexibility, the hose tends to sag and must
therefore be fixed at ca. 1m intervals.
► The ducting of the air inlet and air outlet to and from
the appliance takes place by means of special air
hoses. These are highly flexible, heat insulated and
are self-extinguishing.
