Air routing
For internal installations, connect the
air side with flexible air hoses or via
air ducts and flexible connections
routed to the outdoors. observe
previous instructions regarding
acoustic emissions. limit the velocity
at the air inlet and discharge to a
maximum of 2 m/s, relative to the
free cross-section of the air grille
(noise development). Always prevent
a short-circuit between the air inlet
and discharge. it would be practical to
route the ventilation air supply across
a corner or a cross. if the inlet and
discharge apertures are at the same
level, ensure a minimum clearance
of 3 m. Provide a dividing wall or
shrubs, if necessary. the weather or
bird protection grilles should be easily
removable for cleaning purposes.
Acoustic emissions
never install the heat pump
immediately below or adjacent to
bedrooms. For hard floor areas (e.g.
tiles), we recommend placing a
rubber mat below the appliance. Good
sound insulation can be achieved
by using a concrete plinth with a
rubber mat underneath the appliance.
insulate pipes through walls and
ceilings against structure-borne
noise transmission. the compact heat
pumps series wPl are characterised
by a particularly quiet operation.
nevertheless, incorrect installation
can, under unfavourable conditions,
lead to unwanted high noise levels.
Cellar – in a corner
the example shows the installation
of a compact heat pump in a cellar.
routing the air via different sides of
the building effectively prevents short-
circuits between discharge and inlet
air. the inlet and discharge grilles
should be sized so that discharge
free ventilation cross-section is large
enough.
Cellar – separate ducts
when installing a compact heat pump
in the cellar, connection of air ducts to
two cellar light wells on the same side
of the building is possible, subject to
the distance between the light wells
being sufficient to prevent a thermal
short-circuit. the inlet and discharge
ducts are protected by a cover against
leaves and snowfall.
Cellar – common duct
when installing a compact heat pump
in the cellar, connection of air ducts to
a common cellar light well is possible,
subject to thermal short-circuits being
reliably prevented. in this example the
inlet flow is diverted. A dividing wall
between the air inlet and discharge
inside the light well and a deflector
outside the light well prevent a
thermal short-circuit to the greatest
extent.
Note
observe particularly the following
points for this installation type:
 avoid thermal short-circuits
 provide a suitable condensate
drain
 provide a sufficiently large
free cross-section for inlet and
discharge grilles
