By purchasing this system you have acquired a modern
and efcient heating system. Ongoing quality controls
and improvements as well as functional checks at the
plant guarantee you technically perfect equipment.
Please read through this documentation carefully. It
contains important information for correct installation and
safe and economical operation of the system.
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 specia-
list staff and commissioned by a customer service com-
pany trained to do so by IDM-Energiesysteme GmbH.
When working on the heat pump, the system must be
de-activated and secured against re-activation. In additi-
on, all safety instructions in the relevant documentation,
stickers on the heat pump itself and all other applicable
safety regulations must be observed.
Transport:
During transport, the heat pump must never be inclined
more than 30°. The heat pump must not be transported
on the connection ttings. The transport packaging may
only be removed if the heat pump is located at its installa-
tion location.
Sound emission:
TERRA heat 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 tted door.
Construction drying and screed heating
The heat pump is not designed for the increased heat re-
quirements when drying out construction work or heating
plaster or screed. This must be covered by equipment
provided by the customer if required.
Servicing and maintenance:
Regular maintenance as well as checking and servicing
of all system components guarantee its safe and eco-
nomical operation in the long term. To achieve this, we
recommend a maintenance contract with the relevant
customer service company.

Description
The TERRA CL is an air source heat pump with suction
gas scroll compressor with large multi-row Al/Cu, nned
evaporator.
A special speed-controlled radial fan means that large
ow rates can be achieved at low speeds.
A plate heat exchanger is used as the condenser. The
machine frame consists of a steel-reinforced plastic pro-
le. The cover panels are foam-insulated. This means that
the casing is completely protected from cold bridges and
has excellent sound insulation.
The heating controller is a modern controller that fulls all
the functions of standard heating regulation.
The heat pump has a compact design, the evaporator is
ready-tted in the top of the heat pump casing. The heat
pump is lled with refrigerant and is checked in the facto-
ry before shipping for reliable functioning.
Application range
For monovalent heating of single-family and two-family
homes under appropriate environmental conditions. The
building must be equipped with low-temperature heating
(e.g. underoor heating, wall heating, low-temperature
radiator heating).
The lower the maximum heating temperature
is set, the higher the efciency of the heat
pump.
TERRA CL heat pumps work using the R407C safety ref-
rigerant which circulates in a closed circuit when correctly
mounted and commissioned. This minimises its environ-
mental impact.

Design
The dimensioning of an air/water heat pump should be
such that the bivalence point is between -3 and -10 °C.
This will help ensure that more than 90° of the annual
heating requirement is covered by the heat pump.
The maximum heating output of a building is determined
in the design, including its water consumption require-
ment.
In addition, the standard outside temperature is required.
This is determinated by geographical location and can be
obtained from various institutions.
Example:
Single-family house in Germany
4 persons
Service water consumption requirement:•
4 x 0.25 kW = 1 kW
Heating output required:•
16 kW
Standard outside temperature for Germany:•
- 16 °C
Off-period factor:•

Interior installation
Installation instructions:
Interior installation of the heat pump is recommended.
This means that the work involved in frost protection
and condensation run-off heating can be avoided. It also
means that the inlet air / outlet air can be conveyed to the
heat pump with the least possible heat losses. Various
installation options are described in detail in the following
chapters.
All components of the heat pump are insulated so that no
condensation is formed on the external parts even at out-
let air temperatures of -20°C. However, it is still advisable
to air the room regularly.
The heat pump is decoupled via vibration dampers. The
installation location should consist of a solid base.
Heating connection:
A exible hose set is included as standard for heating
connections. See technical data for appropriate connec-
tion sizes for specic machines. It is advisable to use air
source heat pumps only in combination with a buffer tank
such as the IDM Hygienik Tank.
Condensation run-off:
Air source heat pumps generate condensation during
operation. With larger machines, up to 50l of water can
be extracted from the ambient air per day. The conden-
sation run-off should be conveyed into the waste water
channel via a siphon using the appropriate pipe diameter
for the machine.
Air routeing:
The various air ducts (see accessories for interior ins-
tallation) and wall openings are designed specically for
the relevant machines in question. Efcient and fault-free
operation can only be ensured if the appropriately sized
connection elements are used.
Even light shafts which are too small
enlarge the pressure loss of the air
routeing. These must therefore be of a
sufcient size.
Light shafts must have a rainwater run-off.
Air inlet / air outlet:
The options for how the air inlet and air outlet are desig-
ned are varied.
The list below provides design guidelines:
Air inlet side and air outlet side should always be on •
two different sides of the building.
Openings in the masonry must always be protected •
against the penetration of foreign bodies (leaves, small
animals). To do this, mesh grilles should be tted in
light shafts and weather-shield grilles should be ins-
talled on visible walls.
Wall openings must be created as per the specica-•
tions and insulated against damp penetration using a
closed-pore insulating material (minimum thickness
50mm).
Noise
Noise level in the installation room depends on various
factors such as room size, absorption capacity, reection,
free noise propagation, etc. For this reason, it is important
that the heat pump is situated as far as possible from
noise-sensitive areas. A noise-insulating door should be
tted.
The night-time reduction in the fan speed means that noi-
se can be reduced by up to 4 dB. Noise level on the inlet
and exhaust air openings are also reduced by approx. 4
dB when using air shafts or ducts.
In case of exterior installation, the installation of the heat
pump in a corner can lead to a higher noise level. Super-
position of the sound waves means that noise level can
increase up to 3 dB.
Page 11
Corner installation
A condensation run-off with siphon must
normally be tted opposite the exhaust
opening for the heat pump.
The ideal position for the heat pump has proved to be in a
corner. Wall openings can be prepared by the customer in
advance. These openings must be insulated with closed
pore insulating material (minimum thickness 50mm).
Space required, accessibility:
To guarantee maintenance and operation of the heat
pump, the following minimum distances must be obser-
ved:
Front side (operation and maintenance side) = 800mm
Maintenance side = 500mm
Observing these distances will help ensure problem-free
system maintenance and operation.

Page 12
Exhaust air opening to right Exhaust air opening to left
Based on accessibility, the exhaust air
opening should ideally be on the right-
hand side.
An even, solid installation surface must be selected.
After positioning the heat pump, it must then be made
level. There are adjustable feet on the heat pump for this
purpose.
Customer preparation
Specied dimensions include clearances. A noise-insulating door should be tted. Minimum
thickness of the wall insulation is 50mm.

Assembly instructions - Corner installation
Wall connection is supplied separately. Vertical connec-
tions must be afxed rst. To do this, simply remove the
lm on the rear. The cellular rubber can then be afxed
ush with the external edge of the heat pump.
Additionaly the horizontal elements are also lined on the
front. This will help ensure an optimum seal.
Before the machine is positioned in the corner, a check
should be carried out to ensure that the wall opening
prepared by the customer has been insulated.
The machine can then be moved into the corner.
The heat pump may only be moved with
the panels tted.
If there are any air gaps on the outlet or inlet openings
due to the ground being uneven, this can be corrected
using the adjustable machine feet.
Noise
Noise level in the installation room depends on various
factors such as room size, absorption capacity, reection,
free noise propagation, etc. For this reason, it is important
that the heat pump is situated as far as possible from
noise-sensitive areas. A noise-insulating door should be
tted.
Signicant pressure against the wall
should be avoided.
Page 15
Installation – Standard air duct
If there are no two external walls directly available for
installation, the air ow can be conveyed outwards via
insulated air ducts. Our range includes standard air ducts
which can be connected directly to the heat pump without
adaptation.
There are two ways to do this:
Option 1:
This method is used if there are no two external walls
available. As a short circuit may occur between the sup-
ply and exhaust sides with this method, the inlet and out-
let should be positioned as far apart as possible. The unit
can be separated from any shrubbery by tting dividing
walls if necessary.
Option 2:
This method is equivalent to corner installation. This
method can be used if corner installation is not possible
due to space restrictions or if a gap needs to be bridged
between the heat pump and outlet side.
Air ducts can be connected to the right
and left of the heat pump. Heating and
electrical connections can also be tted
on both sides.

Assembly instructions - Standard duct
Air inlet side:
The inlet-side wall connection is supplied separately. Ver-
tical connections must be afxed rst. To do this, simply
remove the lm on the rear side. The cellular rubber can
then be afxed ush with the external edge of the heat
pump.
Additionaly the horizontal elements are also lined on the
front. This will help ensure an optimum seal.
Before the machine is positioned on the inlet opening,
check that the wall opening prepared by the customer
has been insulated.
The heat pump may only be moved with
the panels tted.
If there are any air gaps on the outlet or inlet openings
due to the ground being uneven, this can be corrected
using the adjustable machine feet.
Signicant pressure against the wall
should be avoided.
Outlet panels:
The outlet panel is mounted using the four clamps sup-
plied.
Duct:
Assemble the duct using the screw set supplied. The
tting length should then be checked.
If the straight duct is too long, two rivets can be bored
open on one side so that the ange can be removed. The
duct can then be cut to length using an angle grinder or
a jigsaw with the relevant blade. The ange can then be
re-tted.
Insulation:
The insulation for the straight duct is supplied separately.
This is self-adhesive and needs to be afxed once the
duct has been cut to the correct length.
Wall connection:
The wall connection is sprayed into the wall opening with
assembly foam. The outlet duct must be connected befo-
re the foam hardens.
If two or more ducts are assembled
together, the duct must be supported
(above or below).
