With the acquisition of this plant you have decided
yourself for a modern and economic heating system
Regular quality controls and improvements,
as well as functional tests in the factory, guarantees
a technically faultless device.
Read these documents attentively.
You will contain important notes and for the sure and
economical operation of the plant.
Installation and maintenance can involve dangers by
high Plant pressures, high temperatures and voltage-carrying Parts andbeing and must be done by experts.
Heat pumps may only be installed by competent experts and put intooperation onlyby a company which
is trained by IDM energy systems GmbH
For work on the heat pump all safety data in the corresponding documents, the sticker at the heat pump
itself and all the othersafety regulations haveto been
observed.
By transport, never incline the thermal pump more
then 15°.
The transportation packing should be removed just
after the thermal pump is positioned at the place of installation.
Terra heat pumps are very quiet in operation due to
their construction.
Nevertheless it is important that the heating room
should be positioned outside of sensitive to noise
living quarter and should be provided with a well closing door closing.
The heat pump isn't setup for the increased need of
heat for drying subfloor or carcass.
This must be done by equipment specially designed
for this task.
Tip for security:
Transport:
Sound emission:
Drying of subfloor orcarcass:
Service and maintenance:
Aregular maintenance as well as a check and
Care of all important plant parts guarantees at last a
safe and thrifty operation of the plant.
We recommend acontract formaintenance.
Cleaning:
If required, the Terra heat pump can be cleaned with
a damp cloth.The use of cleansers is not recommended.

:
The heat pump is filled with refrigerant. This
Cryogen is non-poisonous and not combustible.
In case of damage however, refrigerant is could flow
out of the plant, and could cause superseding of
oxygen.
Due to open fire, toxic disintegration products can ari-
se
By leaving refrigerant (smell)leave theinstallation site
immediately leaving and close the door.

Works at and in the equipment are permitted only for
authorized experts

2.1 Description
Heat pump with gas inlet cooled scroll-cachetcompressors, with large dimensioned stainless steel
heat exchangers as vaporizer, condenser on a robust frame with heat and noise emission insulated casing.
A console with all operational and safety equipment
is integrated in the body.
The device is prepared for the operation with a weather compensating flow temperature control (accessory).
The heat pump is accomplished in compact design
and the vaporizer is already built inside the heat
pump casing.
2.2 Range of operation
For a monovalent heating of one totwo family homes
with geothermal usage, whereby the house should
be equipped with a low temperature heating (e.g. under floor heating, wall heating or low temperature radiators)

2. Heat pump for Brine or Groundwater operation
TERRAheat pumps operate with the safety coolant R
407 C, which circulates, if properly installed in a closed circuit and is practically no hazard for the environment.
As lower the maximal flow temperature is
designed as higher is the heat pump efficiency

2.6 Operational limits
Seite 5
TERRA-S resp. TERRA-W heat pumps must be
only operated with the heat carrier medium brine
or Groundwater. Other heat carrier media are not
permitted.
Further it is not allowed to heat other fluids than
heating water.
(Heating water quality see page 10)
Heat pumps have natural pressure resp. tempe-
rature operation limits. (See illustration)
It is not allowed to operate the TERRAheat pump
outside these operational limits.
With groundwater heat pumps the groundwater
has to have a certain waterquality,see page18. If
one of those values is below or exceeds these limits it is not allowed to use the groundwater heat
pump with this groundwater.
There are several safety applications integrated
to protect the heat pump
A combined high and low pressure manometer which can be reset by switching the machine off and backon.
Max. flow temperature limit with will automatically reset.
A Thermorelais which can be reset by switching the machine off and back on.
Internal winding protection
With groundwater heat pumps: minimum temperature limit for the groundwater return temperature and integrated water pressure
switch.
