1. General description
1.1. General information
By purchasing this system you have decided in favor

tinuous quality controls and improvements as well as
functional checks at our production facilities guaran-
tee technically error-free equipment.
Please read this documentation carefully. It con-
tains important instructions for a correct installa-
tion, for the reliable and an economical operation
of the system.
1.2. Safety instructions
Installation and maintenance operations can be as-
sociated with dangers resulting from high system
pressures, high temperatures and voltaged parts.
Heat pumps may only be installed by competent spe-
cialist and exclusively put into operation by a cus-
tomer service specialist trained for that purpose by
IDM-Energiesysteme GmbH.
If maintenance work is being done on the heat pump,
disconnect the system and ensure that it is volt-free
and provided with a safeguard to prevent unintention-
al restarting. Furthermore all safety instructions in the
respective documentation or on instruction plates af-
¿[HGWRWKHKHDWSXPSLWVHOIUHVSDOORWKHUSHUWLQHQW
safety regulations shall be observed.
1.3. Transport and storage
In transporting the heat pump ensure that it is never
tilted by more than 30°. Do not remove the transport
packaging until the heat pump has reached its instal-
lation location. Heat pump components must not be
stored outside. Heat pumps must not be stored in
humid rooms or dusty environments. The transport
¿[WXUHV DV GHVFULEHG LQ WKH IROORZLQJ DVVHPEO\
instructions are used to transport the heat pump
PDQXDOO\7KHWUDQVSRUW¿[WXUHVPXVWQRWEHXVHGIRU
transporting the components with a crane or similar
hoisting equipment.
1.4. Sound emission
AERO heat pumps run extremely smoothly due to
their construction. It is nevertheless important to
ensure that the heating room is located beyond the
noise-sensitive living area and furnished with a well-
closing door.
1.5. &RQVWUXFWLRQGU\LQJDQGÀRDWLQJVFUHHG

has to be heated with the electric heating element!
1.6. Service and maintenance
Regular maintenance as well as an inspection and
maintenance of all important system components
guarantees a reliable and low-price operation of the
system in the long term. We recommend you to sign
a maintenance contract with your competent cus-
tomer service.
1.7. Cleaning
If necessary, the AERO heat pump can be cleaned
using a moist cloth. The use of cleaning agents is not
recommended.
The air vent package in the air heat exchanger
has to be inspected regularly and cleared of any im-
purities (e.g. leaves,...), if necessary.

opening the tube clamp on the condensate bin. Now
the bin and the tube can be inspected and cleaned.
To prevent water damage, the conden-
sate bin and the condensate hose have
to be checked regularly for contamination.

General description
For the installation of the heat pump all
pertinent national and international lay-
ing, installation, accident prevention and
safety regulations in connection with the
installation of pipeline systems and elec-
tric components and equipment as well as
instructions in this assembly manual must
be observed.
1.8. Ice-covering weather-shield grilles
Depending on the weather and outdoor humidity, it
may happen that there will be formed an icy coverng
on the wheather-shield grilles of the heat pump. This
HႇHFW LV FRPPRQ RFFXULQJ LQ QDWXUH 7KLV FRYHULQJ
must be removed by the heat pump operator during
this weather periods.
1.9. Installation area
1.10. Information on environmental protection
- In order to minimize oscillations and sounds
within buildings, heat pumps should be decou-
pled as far as possible from the building mass.
It is principally recommended to avoid installing

be omitted around the heat pump.
- The installation in wet or damp environments or
in areas exposed to dust or explosion hazards is
non-permissible.
- If refrigerant escapes from the installation site,
this must not enter adjacent rooms, stairways,
yards, corridors or drainage systems and a
hazard-free drainage must be ensured.
- In the case of danger, leave the installation site
immediately.If the size of the installation site falls
below the requested minimum size, this has to
be designed as machinery room in compliance
with EN 378.
- ,I WKH HPHUJHQF\ YHQWLODWLRQ LV QRW VXႈFLHQW
mechanical ventilation must be provided. A
mechanical ventilation shall be installed with
an independent emergency control beyond the
installation site and near the door to that area.
- Heat pumps must not be installed in rooms with
KLJK(0&ORDG$LULQWDNHVDQGRXWOHWVKDYHWREH
safeguarded against theft by appropriate on-site
measures.
- The AERO ILM heat pump has to be
installed in a frost-proof room! (room

Heat pumps are electronic devices of
high-quality material which must not be
disposed of in the same way as house-
hold waste. They must be disposed of in
a professional and appropriate manner
pursuant to the regulations of the local
authorities. Disposal contrary to the
regulations may lead damage the envi-
ronment and health with the exception
of sanctions imposed on law breakers.
1.11. Piping and pipe-wall-ducts
All pipelines and wall ducts must be discharged in
compliance with standards, according heat-insula-
tion, sound-decoupling and water-carrying pipes in a
frost-proof manner.
1.12. Installation of additional components
The installation of additional components which have

function. No warranty or liability shall be assumed for
any damage resulting therefrom.
1.13. Standards and guidelines
These comprise among others:
- the generally valid accident prevention and safety
regulations
- the provisions regarding environmental protection
- the regulations of the professional associations
- the pertinent laws, standards, regulations and pro-
visions, e.g. DIN, EN, DVGW, VDI and VDE.

and is tested in the plant to ensure its perfect function.
1.15. Application range
For monovalent heating and cooling of detached and
semi-detached houses in appropriate climatic envi-
ronments. The building should be furnished with a

The heat pump must be used only for domestic, but
not for commercial operation, eg production of pro-
cess heat.
AERO ILM heat pumps function with the safety re-
frigerant R410A which, if in the event of a proper as-
sembly and installation circulates in a closed circuit,
represents practically no environmental impact.

3.3. Limitations of use
The heating of liquids other than heating water is not permitted (see heating water quality). Heat pumps
are naturally subject to pressure or temperature-dependent operating limits (see diagram below). Operation
outside these limits is not permitted.

Installation instructions AERO ILM

To prevent water damage, the conden-
sate bin and the condensate hose have
to be checked regularly for contamination.
Even when installing with light shaft, the
condensate drain must be checked for
contamination. The discharge hose can

ing the hose clamp. This allows to inspect
and clean the bin and the hose.
In coastal installation, a minimum dis-
tance of 5 km from the coast must be
observed. If this safety distance is not
observed, there could occur increased
corrosion. These cases are excluded from
the guarantee.

5.1. Installation instructions
The AERO ILM (HGL) is only designed for interior
installation. By installing this system in the interior the
expenses for frost protection and condensation run-

lation options to ensure that the inlet air / outlet air is
fed to the heat pump with a minimum loss. These are
described in detail in the following chapters.
All components of the heat pump are insulated in
such a way to ensure that even in the event of outlet

on the outer parts. It is nevertheless recommended to
ventilate the room regularly.
The heat pump is decoupled by a vibration dampers.
The installation location must have a solid surface.
The heat pump can be leveled by the 4 height adjust-
able feet (up to 50 mm).
2 pieces of insulating mat are also included in the
delivery contents with the heat pump in order to avoid
noise. These 2 mats are placed under the heat pump.
They are both furnished with 2 openings for the ad-
justable feet of the heat pump.

location depends on various factors, such as room

sound propagation etc. It is therefore important to
ensure that the heat pump is installed, if possible,
beyond the noise-sensitive area. The heating room
should be furnished with a sound-insulating door.

Air source heat pumps generate condense water
during operation. Per defrosting cycle, i.e. within 2
minutes up to 10 l of condensate can accumulate.
The factory-provided and pre-mounted condensate
