General information
By purchasing this system you have acquired a
modern and effi cient heating system. Ongoing qua-
lity controls and improvements as well as functional
checks at the factory guarantees you a technically
perfect equipment.
Please read through this documentation carefully.
It contains important information for correct in-
stallation and safe and economical operation of
the system.
1.1. Standards and directives
For the installation of the heatpump follow all relevant
national and international piping- and installation re-
gulations and the instructions given of this Installation
instruction.
Amongs others comparing the following:
- the general 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 companies
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
specialist staff and commissioned by a customer
service company trained to do so by iDM Energiesys-
teme GmbH.
When working on the heat pump, the system must
be shut-off and secured against unintentional restart.
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 TERRA SWM should be installed in a frost-proof
room. The Room temperature should be between
5°C and 25°C!
To minimize vibrations and noise, the heat pump must
be isolated from the building structure. Basically,
setting up of the heat pump on light weight design
ceilings must be avoided. In case of a fl oating screed,
the screed and the sound damping have to be omitted
around the heat pump.
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 off safely!
In case of danger, the plant room has to be evacua-
ted 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 infl uences from other installations!
If the minimum size of the installation room falls below
the required value as described in the technical data,
the room must be designed as an machine room accor-
ding to EN 378!
(C) IDM ENERGIESYSTEME GMBH Installation instructions TERRA SWM 5
General information
1.5. Sound emission
The TERRA SWM is very quiet in operation thanks to
the design. It is however important that the boiler room
is situated as far as possible from noise-sensitive
living areas. A well-closing door should be installed.
1.6. Installing additional components
The installation of additional components which have
not been tested with the equipment may impair func-
tion. No warranty or liability is assumed for damages
resulting from this.
1.7. 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 requi-
red.
1.8. Cleaning
If necessary, the TERRA SWM can be cleaned with
a damp cloth. The use of cleaning agents is not re-
commended.
1.9. Servicing and maintenance
Regular maintenance, control and servicing of all
system components guarantees safe and economi-
cal operation in the long term. To achieve this, we
recommend a maintenance cotract with the relevant
customer service company. Only original spare parts
which meet the requirements of iDM may be used!
1.10. Service
For technical information please contact your relevant
iDM customer service department.
1.11. Warranty and guarantee
Warranty and guarantee conditions are included
in the purchased documents. For questions please
contact your relevant customer service department.
1.12. 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
equipment.
Dispose the device properly and do not damage the
pipes of the refrigerant circuit.
On the refrigerant side the TERRA SWM is
„hermetically tight“.

2. Description
2.1. Description
The iPump is a brine-water heat pump with a Scroll-
compressor with Inverter-technology.
The microprocessor controller NAVIGATOR 2.0 en-
sures effi cient operation of the heat pump. The heat
pump system is controlled as needed and is equipped
with a variety of monitoring-, security- and reporting
functions.
By default, one heating circuit can be regulated. Sys-
tems up to six heating circuits can be realized with
optional heating circuit extension modules.
A colored 7“ touch display simplifi es the operation of
the heat pump.
The connections of the brine lines are inside the heat
pump. The connections for heating lines are also
inside. All connections can be feed out either on the
right or left side of the heat pump.
The LAN-connection, the cable inlet for the sensors
and the power supply are on the backside. The USB-
port is integrated in the front part and is closed by a
stopple when delivered.
TERRA SWM is available with HGL or with HGL and
process reversal (P). Thereby the heat pump can be
used for cooling.
The TERRA SWM heat pump is working with the sa-
fety refrigerant R410A. It circulates in an closed circuit
when installed and commissioned properly, meaning
that there is no environmental impact.
The lower the maximum fl ow temperature
is set, the higher is the effi ciency of the
heat pump.
2.2. Application range
The TERRA SWM can be used for monovalent hea-
ting and cooling of single and multiple dwellings with
ground heat utilisation.
In this case the building should be equipped with low-
temperature heating (e.g. underfl oor heating, wall
heating, low temperature radiator heating).
The heat pump may only be used for domestic and
not for purely commercial operation!

Description
2.9. Performance data - cooling according to EN 14511
In order to guarantee a correct cooling mode, when working with unregulated direct-heating circles (without
cooling buffer), the following 3 requirements have to be fulfi lled:
1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.
Minimum volume 80 lt.
2. To ensure the minimum fl ow rate of heating site, appropriate zones have to remain open all the time.
Minimum fl ow rate 1.01 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 S30°C/W18°C. Minimum cooling power consumption 2.8 kW
All 3 requirements must be fulfi lled independently. This is possible applying the NAVIGATOR Pro. The entire
distribution system has to fulfi ll the 3 mentioned requirements.
To ensure a large cooling demand, the cooling limit has to be set as high as possible.

Description
2.10. Limits of use
The TERRA SWM must only be used with the heat
media of brine or groundwater. No other heat media
are permissible. In addition, the heating of other fl uids
as heating water is not permitted (for heating water
quality, see page 29).
Heat pumps are by nature subject to limits of use
based on pressure and temperature (see diagram).
It is not permissible to operate the TERRA SWM out-
side these limits of use.
Note:
The following safety devices are included to protect
the heat pump against faults:
- electronic high- and low pressure monitoring
- Flow-maximum temperature limiter with automati-
cally reset via the NAVIGATOR 2.0 control

Transport
In order to avoid damages during transport, the heat
pump should be transported to its fi nal installation
site in packed condition on the wooden palett with a
forklift or hand lift truck.
The components and the tubing of the heating- and
heat source site must never be used to transport the
heat pump.
When heat pump is lifted from the wooden palett,
there is a risk of tilting. Therefore, the device must be
lifted and secured with a suffi cient number of persons.
The weight of the heat pump must be considered!
Transport of the heat pump via stairways
The heat pump can be lifted down the stairways step
by step with a sack barrow. A suffi cient number of
persons for securing the device during the transport
shall be present.
If the heat pump must be transported without the
wooden pallet and the protective wooden crate,
it is important that there will be no damage on the
housing.
3. Transport
Sack barrow
Transport facility over stairways for the TERRA SWM
Transport with Hand lift truck
Transport with fork lift
When transporting, the TERRA SWM may not be tilted more than 45°
