2. Heat pump installation
2.1. Transport and handling
The heat pump must be transported vertically and not exposed to adverse weather conditions. It can be lain carefully on its rear side
to facilitate transportation to the installation site.
NOTE
Do not tilt the heat pump more than 45º, since this could impair proper equipment operation.
Due to its heavy weight, the heat pump should be handled by two workers using a forklift for heavy
loads.
2.2. Dimensions and connections
The overall dimensions and hydraulic connections of the ecoGEO Compact and ecoGEO Basic heat pumps are described below.

NOTE
During cover disassembly, take care to remove the control panel cable without damaging it.
2.5. Recommended positioning
Choose a dry place where there is no risk of frost. Avoid installation against bedroom walls or walls of other rooms where noise
emissions can be annoying. If possible, install the heat pump with the rear part pointed toward an exterior wall. Avoid installation
near a corner, since this can amplify noise emission levels.
The heat pump should be installed on a stable base that can support the total weight of the equipment and the operating fluids in its
interior. Use the adjustable legs to compensate for possible irregularities on the supporting surface.

2.6. Service areas
The minimum recommended distances to be left around the heat pump to facilitate installation, start-up and maintenance work are
indicated below.

Figure 1.7. Minimum recommended service areas around the heat pump (amounts in mm).
The space needed at the back of the heat pump can be either 50 mm or 300 mm, depending on which pipe connection alternative is
chosen, top or rear, respectively.
3. Hydraulic installation
NOTE
The installation schemes included from here on should be considered simply as a guide.
The design of the hydraulic installation must be performed by qualified personnel and in accordance
with applicable local regulations.
3.1. General instructions
The following recommendations should be taken into consideration for proper hydraulic installation.
Avoid excessive strain between the pipes and the heat pump connections to prevent leaks and/or transmission of vibrations.
Flexible hoses should be used for heat pump connections.
Install cut-off valves at all the hydraulic connections to facilitate future maintenance tasks.
Install traps at all the installation points where air pockets can form.
Place heat insulation on all circuit pipes to prevent unnecessary heat loss. Pay special attention to the heating insulation on
the brine circuit pipes, since these can reach temperatures below 0ºC, causing condensation and/or frost.
DANGER!
During installation work on the hydraulic circuits, take special care to prevent liquid from spilling on the
internal electrical heat pump components, which could cause personal injury due to electrocution
and/or poor equipment operation.

Do not install components that might cover the inlet or outlet of the safety valves; this could lead to a
risk of some of its components breaking and cause injuries and/or material damage.
3.2. Brine circuit
The ecoGEO heat pumps can be used with horizontal or vertical (A) geothermal brine systems or by using groundwater (B).
Aerothermal brine can also be used by replacing the geothermal collector with one or more ecoGEO AU12 aerothermal units (C).
Finally, hybrid collection can be obtained by combining a geothermal collector with one or more ecoGEO AU12 aerothermal units
(D).
Geothermal brine systems
Brine systems with more than one circuit must be connected in parallel, so the flow rate through each one is similar.
Groundwater brine systems
Groundwater brine systems must use a midway exchanger to prevent the heat pump evaporator from corrosion, freezing or getting
dirty.
Hybrid brine systems
In hybrid brine installations, the aerothermal collector and the geothermal collector must be connected in series so the antifreeze
mixture circulates first through the aerothermal collector and then through the geothermal collector.
On the other hand, open / close 3-way valves must be installed between the outlet and return of each collector so the collector can
be bypassed when it is not in use.
Figure 1.8. Brine circuit connection options.
Integrated components
The following brine circuit components are included within the heat pump.
Variable speed and high efficiency outlet pump (energy class A).
Expansion vessel with a capacity of 8 litres, with pre-adjusted pressure of 0.75 bar (pressure gauge).

Drain valve.
Installation instructions
Follow the instructions below to wire the brine circuit.
Install the necessary components to carry out the filling/discharge of the return pipe.
Install a particulate filter in the return pipe with a mesh size no greater than 1 mm. It is recommended to install shut off valves
immediately before and after the filter to make it easier to clean or replace.
Check that the volume of the expansion vessel integrated in the heat pump is capable of absorbing any overpressures from
the circuit. If this volume is not enough, install a supplementary external expansion vessel.
If necessary, adjust the pressure of the expansion vessel integrated in the heat pump to guarantee that the circuit remains
pressurised at all points.
3.3. Heating / Cooling circuit
The ecoGEO heat pumps can be connected to various types of heating / cooling systems, both directly and by separating buffer
storage tanks. On the other hand, these enable control over several devices that are external to the heating / cooling system directly
from the heat pump's electrical panel.
Heating / cooling system
The ecoGEO heat pumps are designed to be used with heating systems with nominal outlet temperatures of up to 55ºC; such as
underfloor heating systems, low temperature radiators or convectors. They are not recommended for use in heating systems that
require higher temperatures.
The ecoGEO heat pumps can be used with cooling systems with nominal outlet temperatures of up to 7ºC, such as convectors and
underfloor cooling systems.
Special care should be taken in the design and control in installations with underfloor cooling, to prevent problems of condensation
on floors.
The models that are not equipped with integrated passive cold allow control of external passive cooling equipment.
Direct installation
In simple heating / cooling systems, ecoGEO heat pumps can be installed directly into the distribution system, in systems with
underfloor heating, low temperature radiators and convectors.
Figure 1.9. Wiring scheme directly to the heating / cooling system.

Installation using buffer storage tanks
If required by the application, the heat pump can also be connected to the heating / cooling system using a buffer separator tank. To
do so, it is equipped with two temperature probes that are used to control a buffer storage tank for heating and a buffer storage tank
for cooling. In installations where there is only one buffer storage tank for heating and cooling, both probes have to be installed in
the storage tank. Install the temperature probes at the points where heating / cooling production begins. Heating / cooling production
is stopped by the return temperature probe installed inside the heat pump.
Figure 1.10.Wiring scheme using two buffer storage tanks.
Figure 1.11.Wiring scheme using a single buffer storage tank.
Outlet units
These can manage as many as four different outlet temperatures. This is done by managing one direct outlet unit and three combined
outlet units. The combined outlet units have to use modulating 3-way valves with an analogue signal of 0-10Vdc. Each outlet unit has
independent terminals for heating and cooling demands. These signals are supplied with 24Vac or 24Vdc voltage.
