General information
1.2. General information
By purchasing this system you have acquired a
modern and efficient heating system. Ongoing qual-
ity controls and improvements as well as functional
checks at the plant guarantee you technically perfect
equipment.
Please read through this documentation carefully.
Itcontainsimportantinformationforcorrectinstallation
and safe and economical operation of the system.
1.3. Safety Instructions
Installation and maintenance work can be hazardous
due to high system pressure, high temperatures and
live parts and may only be operated by specialist
staff.
Heat pumps may only be installed by competent spe-
cialist staff and commissioned by a customer service
company trained to do so by IDM-Energiesysteme
GmbH.
When working on the heat pump, the system must be
deactivated and secured against reactivation.
In addition, all safety instructions in the relevant docu-
mentation,stickersontheheatpumpitselfandallother
applicable safety regulations must be observed.
1.4. Transport
During transport, the heat pump must never be
inclined more than 30°. The heat pump must not be
transported on the connection fittings. The transport
packaging may only be removed if the heat pump is
located at its installation location.
1.5. Sound Emission
TERRAheat pumps are very quiet in operation thanks
to their design. It is however important that the site of
the heater is situated as far as possible from noise-
sensitive living areas. A noise-insulating door should
be fitted door.
1.6. 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 re-
quired.
1.7. Servicing and Maintenance
Regular maintenance as well as checking and servic-
ing of all system components guarantee its safe and
economical operation in the long term. To achieve
this, we recommend a maintenance contract with the
relevant customer service company.
1.8. Cleaning
If necessary, the TERRA heat pump can be cleaned
with a damp cloth. The use of cleaning agents is not
recommended.
1.9. Installing Additional Components
The installation of additional components which
have not been tested with the equipment may impair
function. No liability is accepted and the guarantee
becomes void in the event of damage caused for this
reason.

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 sanctions for the violator, environ-
mental damages and harm for your
health.
-The TERRA heat pumps should be
installed in a frost-proof room. (Room
temperature should be between 5°C
and 35°C)
-In case of a floating floor screed the screed and
the sound damping around the heat pump have
to be omitted.
-Heat pumps should not be installed in wet rooms
or in potentially dust or explosion-endangered
rooms.
-Gas from refrigerants in plant rooms must not es-
cape 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 eva-
cuated immediately.
-For powering off the cooling facility, a remote
power-off switch has to be installed nearby the
door of the plant room.
-In case a natural ventilation is not possible, a
mechanical 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.
Note for the installation of the heatpump
follow all effective national and inter-
national piping- and installation rules
same as rules for accident prevention and
safety regulations when installing pipeline
systems and electrical components and
equipment as well as the instructions of
this Installation instruction.
Thereto belongs among other things:
- 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 companies

Description
2. Description
2.1. Description
Heat pump with suction gas cooled scroll compressor
with generously sized stainless steel heat exchangers
as evaporator and condenser built on a robust frame
and fitted with a heat and soundproof casing.
The heat pump also contains an electrical panel with
the Navigator Control and with all the switching and
safety mechanisms built-in.
The heat pump has a compact design, the evaporator
is already fitted in the heat pump housing. The heat
pump is filled with refrigerant and checked to ensure
it functions correctly. It is suitable for brine circuit sur-
face collectors, brine circuit deep boreholes, as well
as for ground water use.
2.2. Application range
For the monovalent heating of detached and semi-
detached houses with geothermal heat utilisation.
When doing so the house should be fitted with a low
temperature heating system (e.g. underfloor heating,
wall heating, low temperature radiator heating).
TERRA heat pumps work with the safety refrigerants
R 407 C or R 134 A which, when properly installed
and commissioned, circulate in a closed circuit and
therefore have virtually no environmental impact.
2.3. Scope of delivery
- Heat pump unit with suction gas cooled scroll com-
pressor
- Stainless steel plate heat exchanger as condenser
- Stainless steel plate heat exchanger as evaporator
- Refrigerant collector and dryer
- Thermostatic expansion valve
- Refrigerant inspection glass
- Refrigerant heat exchanger
- High pressure and low-pressure limiter
- Electrical panel with Navigator Control
- Stable base frame
- Cladding, insulated against heat and noise
-4flexible connection hoses
- Start-up current limiter for compressor
2.4. Accessories
- Brine surface collector made of plastic piping Ø 25
x 2.3 mm in rings for each 100 m, incl. distributors
and connection material and brine circuit pump
- Expansion set for 2 additional mixer circuits
- Charging pump assembly with pump 2 shut-off
valves and pump beater
- Safety heat exchanger (Groundwater heat pumps)
Thelower themaximum flowtemperature
is set, the higher the efficiency of the heat
pump.
The respective charging pumps are not
included in the scope of delivery. These
can be ordered as accessories.

2.7. Operating Limits
TERRA-S/W heat pumps may only be used with heat
conducting media, brine or ground water. Other heat
conducting media are not allowed.
Furthermore, the heating of other liquids as heating
water is not permitted (heating water quality see
Page 25).
By definition, heat pumps are subject to pressure
or temperature-dependent operating limits (see dia-
gram).
The operation of the TERRAheat pump outside these
operating limits is not allowed.
Note:
- The following safety mechanisms are provided for
the safety of the heat pump against potential mal-
functions:
- Combined high and low pressure switch with auto-
matic locking or unlocking by switching the system
off and on (after 3 errors within 24 hours).
- Flow maximum temperature limit with automatic
reset via the Navigator Control.
- Start-up current limiter with rotating field monitoring,
motor current monitoring and phase monitoring for
the compressor.
- Internal winding protection in the compressor
