General information
By purchasing this system you have acquired a
modern and efficient heating system. Ongoing qua-
lity controls and improvements as well as functional
checks at the factory guarantee you technically per-
fect equipment.
Please read through this documentation carefully.
It contains important information for correct
installation and safe and economical operation of
the system.
1.1. Standards and directives
Note for the installation of the heatpump follow all
effective national and international piping- and ins-
tallation rules and the instructions of this Installation
instruction.
Amongst others comparing the following:
- the general effective rules for accident prevention
and safety regulations
- the regulations for environmental protection
- the provisions/regulations of the professional asso-
ciations
- the effective laws, standards, guidelines and regu-
lations e.g. DIN, EN, DVGW, VDI and VDE
- regulations of the local suppliers/supply company
1.2. Safety instructions
Installation and maintenance work can be hazardous
due to high system pressure, high temperatures and
live parts, and may only be carried out by specialist
staff.
Heat pumps may only be installed by competent spe-
cialist staffand commissioned by a customer service
company trained to do so by iDM-Energiesysteme
GmbH.
When working on the heat pump, the system must be
shut-offand secured against re-activation.
In addition, all safety instructions in the relevant do-
cumentation, stickers on the heat pump itself and all
other applicable safety regulations must be observed.
1. General information
1.3. Storage
Heat pump components may not be stored outdoors.
Heat pumps should not be stored in wet rooms or in
potentially dust rooms.
1.4. Installation room
The internal unit of the iPump A should be installed in
a frost-proof room. The Room temperature should be
between 5°C and 25°C.
To minimize vibrations and noises, the heat pump
must be isolate from the building structure. Basically,
the setting up of the heat pump on lightweight design
ceilings must be avoided. In case of a floating floor
screed the screed and the sound damping around the
heat pump have to be omitted.
The installation in wet rooms or in potentially dust or
explosion-endangered rooms is not allowed.
Gas from refrigerants in plant rooms must not escape
into vicinal rooms, stair rooms, courtyards, walks or
into the drainage system of the building. The gas has
to be channelled offsafely.
In case of danger, the plant room has to be evacuated
immediately.
In case a natural ventilation is not possible, a me-
chanical ventilation has to be provided. A mechanical
ventilation has to be equipped with an independent
emergency control outside of the machine room near
the door.
Heat pumps should not be installed in rooms with high
electromagentic influences from other installations.
If the minimum size of the installation room falls below
the required value, the room must be designed as an
machine room according to EN 378!

general information
1.5. Sound emission
The iPump A outdoor unit is very quiet in operation
thanks to the design. It is however important that
the site of the heater is situated as far as possible
from noise-sensitive living areas. This also applies to
refrigerant connection lines between the outside- and
the indoor unit.
Also the boiler room where the indoor unit of the
iPump A is installed should be placed outside of the
noise sensitive living area. The boiler room should be
furnished with a good lockable door.
1.6. Ice-covering outdoor unit
Depending on the weather and outdoor humidity, it
may happen that there will be formed an icy covering
on the protective grids of the heat pump. This effect
is common occuring in nature. This covering must
be removed by the heat pump operator during this
weather periods.
1.7. Installing additional components
The installation of additional components which have
not been tested with the equipment may impair its
function. No liability is accepted and your guarantee
is void in the event of damage caused for this reason.
1.8. Construction drying and screed heating
The heat pump is not designed for the increased heat
requirements when drying out construction work or
heating plaster or screed. This must be covered by
equipment to be provided by the customer if required.
1.9. Cleaning
If necessary, the internal and the outdoor unit of the
iPump A can be cleaned with a damp cloth. The use
of cleaning agents is not recommended.
1.10. Servicing and maintenance
Regular maintenance control and servicing of all
system components guarantee its safe and econo-
mical operation in the long term. To achieve this, we
recommend a maintenance contract with the relevant
customer service company.
Only original spare parts which meet the requirements
of iDM may be used!
1.11. Service
For technical information please contact your relevant
iDM customer service department.
1.12. Warranty and guarantee
Warranty and guarantee conditions are included
in the purchased documents. For questions please
contact your relevant customer service department.
1.13. Disposal
Heatpumps are electrical equipment made from
high valuable materials, which are not allowed to be
disposed like normal household garbage, but have to
be disposed professional and proper according the
regulations of the local authorities.
A non-proper disposal can cause, apart from sanc-
tions for the violator, environmental damages and
harm for your health.
This device is characterized according to the euro-
pean directive 2012/19/EU on waste electrical and
electronic equipment (Waste electrical and electronic
equipment - WEEE). The guideline provides the
framework for an EU-wide return and recycling of old

acoustic evaluation
2. Acoustic evaluation
Sound power level
The sound power is the sound energy per second
emitted of a noise source. The sound power level is
specific to the source of sound, independent of dis-
tance and direction and enables an easy comparison
of different sound emitting devices. The sound power
can only be determined via mathematical calculation
according to international standards of the series
ISO 3740 - based on sound pressure level measure-
ments - as well as ISO 9614, which is based on the
measurement of sound intensity. The sound power
level of the heat pumps can be found in the technical
specifications.
Sound pressure level
In contrast to the sound power level, the sound pres-
sure level, which is caused by a noise source can be
measured. The measured sound pressure is depen-
dent on the distance from the noise source and the
receiver location (geometrical divergence) as well as
the local conditions. As the sound pressure level is a
measure of the loudness of noise sensed by humans,
the legislation defines limit values, that must not be
exceeded.
Sound-propagation-outdoor
With increasing distance from a point noise source,
the sound power is distributed on an increasing area
due to spherical spreading. Therefore, the sound
pressure level is continuously decreasing with in-
creasing distance from the noise source to receiver
location. Doubling the distance leads to a reduction of
the sound pressure level of 6 dB(A). Besides the di-
stance from the installation site of the heat pump the
sound, the installation situation and local conditions
also have significant impact on the resulting sound
pressure level at the relevant place of immission.
Major factors of influence are:
- sound attenuation by massive barriers e.g. buil-
dings, walls or different terrain.
-reflection on acoustically hard ground e.g. glass
facade and stone surfaces
- attenuation due to sound absorbing porous sur-
faces e.g. grass, trees
- reinforcement/reduction of by wind speed/direction
Noise immission
The noise caused by an source at a certain place is
expressed as Immission, the corresponding sound
pressure level is called Immission level.The immissi-
on level at the relevant place of immission can either
be calculated with the iDM-sound calculator.
The calculation of the sound pressure level shall be
calculated by means of the following examples for
typical installation situations of the outdoor unit.

acoustic evaluation
Relevant place of immission
The sound immission have to be determined 0.5 m
in the middle in front of the open window (outside the
building) of the most affected rooms, which need par-
ticular protection. According DIN 4109:1989 rooms
needing particular protection are:
- Living- and bed rooms
- Children rooms
- Work spaces / offices
- Classrooms / seminar rooms
Rating level Lr .
The rating level corresponds to an equivalent conti-
nuous sound pressure level associated with a specific
period. The rating level is determined for both rating
periods „day“ (6 am-10 pm) and „night“ (10 pm-6 am)
separately. The operation time of the heat pump has
particular impact on the resulting equivalent conti-
nuous sound pressure level. Reducing the operation
time from 16 h per day to 4 h per day the rating level
is reduced by 6 dB(A).
But the equivalent continuous sound pressure level
alone is not sufficient in order to determine the distur-
bing effect of noise. In general noise is perceived very
disruptive, if individual tones are clearly discernable
or the noise is irregular (impulsiveness). These noise
characteristics will be taken into account by applying
a surcharge. Additionally, daytimes with increased
sensitivity are taken into consideration. According the
„TA Lärm“ the following corrections are applied:
Information incorporation 3 or 6 dB(A)
Impulsiveness 0,3 or 6 dB(A)
Daytimes with increased
sensitivity 6 dB(A)
The rating level Lrshall be obtained by summing the
calculated immission level and the applied correc-
tions of the specific periods.
Finally, the determined rating level can be compared
with legal limit values (e.g. „TA Lärm“).
Standard Immission Values (SIV) - relevant place of
immission outside the building:
Territory SIV-day SIV-night
Industrial area 70 dB(A) 70 dB(A)
Business park,
commercial areas 65 dB(A) 50 dB(A)
Village areas and mixed
areas 60 dB(A 45 dB(A)
Settlement area 55 dB(A) 40 dB(A)
Residential area 50 dB(A) 35 dB(A)
Spa area, hospitals 45 dB(A) 35 dB(A)
In case of sound propagation inside buildings or
structure-borne sound transmission the Standard
Immission Values for the rating level of rooms nee-
ding particular protection are as following:
SIV-day: 35 dB(A)
SIV-night: 25 dB(A)
For the calculation of the rating level according „TA
Lärm“ a calculation tool is provided at the hom page:

Tips for installation of heat pumps
-
Sound reflections areas should be kept as low as
possible
- The installation on acoustically hard ground and
areas with depression in the terrain should be avo-
ided
- The distance from the heat pump and the relevant
place of immission should be as big as possible
- In case of outdoor installation the blow out of air
in direction to the neighbour or relevant receiver
location should be avoided
- The airflow should not be blown directly against
walls as sound reflections lead to increased sound
pressure levels accordingly

3.9. Cooling data detailed iPump A 2-7
To guarantee a correct cooling mode, when working with unregulated direct-heating circles (without cooling
buffer) following 3 requirements have to be fulfilled.
1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.
Minimum volume 54 lt.
2. To ensure the minimum flow rate of heating site, appropriate zones have to remain open all the time.
Minimum flow rate 0.72 m³/h
3. To ensure the minimum cooling output rate of distribution system, appropriate zones have to remain open
all the time. The minimum cooling output rate is 70 % of the minimum cooling output power of the heat-
pump at A35°C/W18°C. Minimum cooling consumption 1.75 kW
All 3 requirements must be fulfilled independently. This is possible via the Navigator Pro. The entire distribution
system has to fulfill the 3 mentioned requirements. To ensure a large cooling demand, the cooling limit has to
be set as high as possible.

3.10. Filling quantity refrigerant
The iPump A 2-7 is pre-filled with refrigerant. Up to a distance of 6 m between indoor unit and outdoor unit no
refrigerant no additional needs to be refilled. For pipe length more than 6 m, the following refrigerant quantities
must be refilled.
3.11. Maximum heigth difference
If the height difference between the indoor unit and outdoor unit is lower than 5 m no oil elevation arc must be
installed before the inclination. In case of a higher height difference the installation must be done after 5 m. The
oil elevation arc must be installed by a certificated service technician. Whether the indoor unit or the outdoor
unit is higher, does not matter. The maximum height difference between indoor unit and outdoor unit is 10 m.

3.12. Linits of use
The heating of other fluids as heating water is not permitted with the iPump A 2-7 (for heating water quality,
see page 51). Heat pumps are by nature subjects to limits of use regarding of pressure and temperature (see
diagram). It is not permissible to operate the iPump A 2-7 outside these limits.
Note:
The following safety devices are included to protect the heat pump against faults:
- High pressure presostat
- Maximum flow temperature limitation with automatic reset via the NAVIGATOR control
- Starting current limiter via inverter technology and performance adjustment

iPump A 2-7 - Heating
Heating
The maximum heat pump flow temperature is the highest temperature that the heat pump can
produce (depending on the heat source temperature) and is then switched off at this value. Due to
the hydraulic spread over the heat pump and the control-related switching hysteresis, it is not pos-
sible to reach this temperature in the heating circuit or in the water heater. The maximum possible
management temperature depends on the hydraulic design and the configuration, and is at least 5
K below the maximum heat pump flow temperature.

Cooling
The minimum heat pump flow temperature is the lowest temperature that the heat pump can produce
(depending on the heat source temperature) and is then switched off at this value. Due to the hydrau-
lic spread across the heat pump, the control-related switching hysteresis and the humidity-dependent
dew point, it is not possible to reach this temperature in the cooling circuit. The lowest possible
management temperature depends on the hydraulic design, the configuration and the actual dew
point on site and is at least 5 K above the minimum heat pump flow temperature.
The maximum power of the iPump A can be limited with the NAVIGATOR 2.0 controller.
