1. General information
Solflex produces SonaSafe acoustic housing for a wide range of Heat Pump, Air
Conditioning and Refrigeration systems.
This manual applies to the following series:
SonaSafe HD* Serie
2. Technical Data
Unique acoustic housing in elegant design made of EPP plastic in RAL7021 black grey.
Through the single EPP parts, the acoustic hood is easy to install and transport. Decisive
for the performance of a heat pump is the air throughput, the inlet and outlet openings
are geometrically optimally adapted to the air flow. The patented internal air diversion
and acoustic housing openings ensure maximum performance and effectiveness. This
achieves optimum performance of the heat pump in whisper-quiet operation. An air
short circuit is prevented by internal partitions. The partitions are lined with sound
absorption material.
The EPP parts are mounted around a specially designed aluminium frame by simply
attaching the individual elements from above onto the aluminium frame that has been
fixed to the floor. The aluminium frame can be loosened at the corners, so that a
retrofitting of the acoustic enclosure is possible. For maintenance purposes, only a few
elements must be removed to reach the heat exchanger or the service level. The
installed refrigerant piping can be easily routed through the side / rear EPP parts. The
holes for the refrigerant piping are to be created on site with a cutter knife.
The power and sound measurement was performed in a certified laboratory. At the test
point, a reduction of up to 6 dB(A) was measured.

3. Performance sound insulation
The sound insulation performance of our sound protection enclosure was measured
by an independent laboratory according to DIN EN ISO 3744.
Measurement method
The sound insulation performance of our sound protection enclosure was measured
by an independent laboratory according to DIN en ISO 3744.
Measurement method
•Measurement of sound power of the calibrated (MP1)
Reference source via a ball surface with 12 microphones. Acoustic data:
Class 2 According to DIN en ISO 3744, as third spectrum and octave
spectrum.
•Measurement of Sound Power (MP2) of the Solflex Sonasafe Sound
Insulation Housing Reference source in the housing via a ball surface with 12
microphones. Acoustic Data Class 2 according to DIN EN ISO 3744, as a
third spectrum and octave spectrum.
•The difference between the two measurements is the sound insulation power
of the noise-isolating housing.
MP1-MP2= Sound insulation performance Sound Insulation Housing
*The measurement tolerance of +/-1.5 dB (A) or tolerance width of 3 dB (A) according
to DIN EN ISO 3744 would finalised not be used and we publish excluding the minimum
sound insulation performance data.

In order to assemble the noise
protection hood, proceed as follows:
1) The noise protection hood must be
installed on a base that is defined as
suitable according to the dimensions. It
can be installed on a foundation that is
manufactured separately or on ground
that is prepared for the installation Start
with the bottom aluminium fame when
installing. Ensure that the aluminium
frame is connected securely to the base
(e.g. using anchor bolts, ground anchors
or fixed screw connections) so that the
entire noise protection hood is attached
securely.
Fig 5
2) Place the installation frame over the
heat pumps outdoor unit and arrange the
frame so that it has an even gab all around
the unit. Check whether the relevant holes
to attach the noise protection hood enable
it to be attached securely. As there are
several options for this, there are no
installation materials included with the HD
noise protection hood for attaching. These
attachments must be provided by the
customer.
Fig 6
3) If the refrigerant piping is laid visibly
from the rear for installation on the
outdoor unit (Fig. 7), the frame must be
installed below the piping. If the
refrigerant piping is installed on the
outdoor unit from the bottom and is not
in the vicinity of the ring elements of the
noise protection hood, you can continue
installation without an opening. If this is
the case, continue installation as
described.

Page 16
Manual HD Acoustic
Housing Version: 20/2020
Fig 7
4) To open the bottom frame, pull the
corner connector out of the aluminium pipe
and install the aluminium pipe below the
refrigerant piping.
Fig 8
5) After you have installed the
aluminium pipe below the refrigerant
piping, re-assemble the corner connector
completely.
The aluminium frame must now be
connected to the base using suitable
attachment materials. If a concrete
foundation /strip foundation or
flagstones are used, you must use
corresponding screws and anchor bolts.
If the noise protection hood is to be
installed on ground that has been
prepared for it, use suitable ground
anchors. If the hood is not attached, is
not secured against wind loads and
operation of the entire system is not
permitted. If the wind load is
expected to be higher than normal,
we recommend securing the hood
with additional storm ropes.
Fig 9
6) Once you have installed the bottom
aluminium frame, place the first ring
element over the outdoor unit (Fig. 10
and Fig. 11) and draw the position of the
refrigerant piping on the ring element
accordingly so that you can remove the
opening from the ring element.

Page 17
Manual HD Acoustic
Housing Version: 20/2020
Lift the ring element off the outdoor unit
again and remove the area that you
previously drew. To remove the opening
for the piping, use suitable tools such as
a cutting knife, a jigsaw or along saw
blade.
Fig 10
7) After you have created the opening,
place the ring element back over the
outdoor unit and secure it around the
aluminium frame.
Ensure that the attachment point
required to attach the buffer at a
later time is in the middle in front of
the fan
Fig 11
8) Now place the enclosed aluminium
supports at the corners of the aluminium
frame and attach them. (Fig. 12) Only
use suitable tools for this, such as a
rubber hammer, in order to prevent
damage to the aluminium profiles.
Fig 12
9) Ensure that all four supports are
completely pushed into the corner
connectors in order to guarantee that
they are aligned (Fig. 13)

Page 18
Manual HD Acoustic
Housing Version: 20/2020
Fig 13
Coution!
Ensure that the outdoor unit is shut
down and secured to prevent a
restare during the installation,
maintenance and repair times in
order to prevent injuries caused by
the fan starting up!
10) Remove the grille in front of the fan
(exhaust side) by removing the four
screws in the corners. Both grilles must
be removed on outdoor units that have
two fans. The grilles are no longer
required to operate the system. The
second ring element can now be placed
on the first ring element (Fig. 12).
Fig 14
11) Now take the baffle plate for the air
outlet and slide it into the EPP ring’s
groove on the air outlet side
Fig 15
Use the fan grille for maintenance
purposes.

Page 19
Manual HD Acoustic
Housing Version: 20/2020
12) Insert the air inlet baffle plate with
the foam insulation side to the inside
towards the outdoor unit. The baffle
plate for the air inlet must rest with the
supporting feet at the bottom on the
aluminium frame. (Fig. 18).
Fig 16
13) To install the baffle plate, guide it
into the opening (groove) provided.
When installing each additional ring
element, the baffle plate for the air
outlet must always be installed through
the opening.
Fig 17
14) The baffle plate for the air outlet
must rest with the side of the foam
insulation directly on the outdoor unit.
Fig 18
15) After it has been installed, as shown
in Fig. 19, the baffle plate is horizontal in
the noise protection hood, directly in
front of and tight to the outdoor unit.

Page 20
Fig 19
16) Now take the baffle plate base for
the air outlet and place it at an angle at
the bottom in front of the condensate
tray.
Fig 20
17) The baffle plate on the base is to
prevent an air short circuit. It is not
screwed on and must be installed flush
to the cover for the air outlet. (Fig. 21).
Manual HD Acoustic Housing
Version: 20/2020
Fig
Fig 21
18) Now take the baffle plate for the air
inlet and install this baffle plate in the air
intake at the rear of the HD noise
protection hood.
Fig 22
19) Insert the baffle plate with the foam
insulation side to the inside with a gap to
the outdoor unit in the first opening on
the ring element. The baffle plate is not
installed directly on the outdoor unit and
must rest with the side supporting feet
at the bottom on the aluminium frame to
intake air.
