3 Installation, connection and
sound emissions
3.1 Transport
Protect the heat pump against severe impact.
Short tipping to one of its longitudinal sides is
permissible.
The casing, cover (in case of external installa-
tions) and the cover with air hose connections
(for internal installation) are separate shipping
units, which will only be assembled to the
base unit on site.
3.2 Installation location
Ensure that the surface on which the heat
pump is to be installed, is horizontal, level,
solid and permanent.
The entire heat pump frame should be in con-
tact with the substrate. Uneven substrates can
detrimentally affect the noise emissions from
the heat pump.
The heat pump must be accessible from all
sides.
3.2.1 Special considerations in case of external
installation
Recommended surface:
- Foundation (Fig. 4)
- Curb stones (Fig. 5)
- Stone plate
A recess (space) must be provided underneath
the heat pump to enable water and electrical
pipes/cables to be connected from below (Fig.
4 and 7).
Ensure a minimum wall clearance on the air
expulsion side of 2 m.
Section 3.3.1 Observe „Sound emissions with
external installations“.
3.2.2 Special considerations in case of internal
installation
Substrate: Concrete or screed
Water and electrical pipes/cables are routed
into the heat pump from the top through the
cover (Fig. 8).
3.3 Noise emissions
3.3.1 Noise emissions in case of external
installation
At the air inlet and air outlet sides, the heat
pump is louder than on the enclosed sided.
Therefore point these two sides away from
noise sensitive rooms of the house (e.g.
bedrooms). The air inlet direction should be,
where practicable, in line with the main wind
direction, in other words, air should not be
drawn in against the wind.
Lawn areas and shrubs can contribute to the
reduction of noise expansion.
Avoid installation on large floor areas off
which sound can bounce (e.g. those covered
with slabs) as well as in between reflective
building walls, both of which could raise the
sound level.
Please ensure that noise should not be emit-
ted through the floor of the heat pump or
through the installation aperture.
The sound power level in external installations
is 65 dB(A) without silencer accessories and 63
dB(A) with silencer accessories.
