3. DESCRIPTION
The Eco solar system is equipment based on
the Carnot principle compression/
refrigeration principle, denominated as a
Thermodynamic Solar System.
The solar panel is the main component and
shall be placed outside for the capture of:
•Direct and diffuse Solar Radiation;
•External air, by natural circulation;
•The effect of wind (almost always
existent);
•Rain
The differences between temperatures,
stimulated by the previously described
agents, guarantees that Klea (ecological
refrigerant fluid) evaporates in the solar
panel's interior. The absence of glass in the
panel allows for increased thermal exchange
by convection.
After passing through the panel, the Klea
fluid is aspirated by the system’s mechanical
component, the compressor, which in turn
raises the temperature and pressure; it is
then transmitted to the water circuit via a
heat exchanger.
Before the Klea fluid returns to the solar
panel it is necessary for a throttling process
occurs, in other words, pressure reduction
that guarantees the liquid state is once again
achieved, completing the overall cycle.
This operational process, in which we ally
technology with the laws of nature (changing
states of a liquid), demonstrates the power
and the potential of the Eco system.

Fig. 13 Panel types (left and right)
5.2 Hot Water Cylinder Installation
The hot water cylinder shall be installed in a
cool and dry location with easy access and
protected from all weather conditions. The
choice of location must allow for easy
assembly of the Thermodynamic Block.
The spot where the hot water
cylinder shall be installed must
have nearby:
•A cold water point
•Hot water point
•Drainage.
•Recirculation (if it exists).
•Electrical point, 230 V/50Hz
Observe that in some hot
water cylinders the
hydraulic connections are
at the back of the device, it
hence being necessary to
consider the spacing between them and the
wall.
5.3 Installation of the Thermodynamic
Block
Before installing the Thermodynamic block,
make sure that the heat exchanger is not in
contact with the resistance casing and the
thermostat. To check this, use a multimeter
(in the continuity position), positioning a
connector on the heat exchanger and the

(compressor or flange) and verify that no
continuity actually exists.
- The Thermodynamic Block is coupled into
the existing flange (at the lower part of the
hot water cylinder).
- Correctly place the sealing gasket before
tightening up between the flanges.
Fig. 14 Coupling of the Block to the hot water cylinder
- Place the heat exchanger into the hot water
cylinder, taking special care upon its
placement, avoiding any damage.
- The coupling of the Thermodynamic Block
to the water cylinder shall be done with the
supplied screws. Tightening of the screws
must be done with a crosshead screwdriver,
guaranteeing air-tightness.
The hot water cylinder shall be properly fixed
in place at the moment the Thermodynamic
Block is positioned, thus avoiding any slight
drop in the unit, considering that there will be
a centre of gravity dislocation.
5.4 Connections

The piping must be properly insulated with a
flexible insulation sleeve made from
(Armaflex type) elastomeric foam in order to
prevent any possible condensation brought
about by low temperatures in the liquid.
Press the nut with the hand by giving some
turns, and apply the pair of keys like seen
before.
5.5 Nitrogen Load
After connections been concluded guarantee
that there is no leakage. The nitrogen load
must be done through the 3 ways valve until
the pressure reaches 12 bar.
Place all the connections under
soap foam and verify if the pressure
is kept constant.
5.6 Vacuum
Use only the vacuum pump to
remove the air and the
humidity from the pipes.
Never use the gas to extract the air or the
humidity from the pipes. That will reduce the
life of the compressor drastically.
All the valves shall be turned off before the
vacuum is start being made. This way the
vacuum will only be done inside the tubes.
5.7 Fluid Load
After carried through the vacuum process the
two valves shall be open for the fluid
circulate all in the system. To enhance that
the system is supplied with a pre-load that is
enough for a maximum length of 10 meters

thermodynamic block. For situations that this
length is exceed is necessary to have to
make adjustments of the load. These
adjustments shall be done by the
compression pipe with the system stopped.
5.8 System Start-up
The Eco commissioning is assured by the
correct installation achieved and by the
respect of all installation instructions.
Increasing water temperature from 10° C to
55° C will vary between 4 to 8 hours,
depending on weather conditions and type of
installation.
It is always possible to do a tune of thermal
expansion valve to adapt the system to a
suitable outside weather conditions by the
temperatures extrapolation method.
Fill the hot water cylinder with water and
purge the existing air, opening a hot water
tap/faucet.
Check if the valves are properlyworking and
if the system is filled with fluid.
There aren’t any failure problem when
starting the system under frost conditions.
To conclude the installation process it is
necessary to connect the electrical cable to
the 230V plug socket, securing the control
panel with two M6 screws.
To turn the apparatus on, press the general
ON/OFF button (1) on the control panel.
Afterwards, press the ON/OFF button on the
Solar System (2). The display must give
information that the system is operational
(ON). Heating up of the water will now begin.
The Eco is equipped with an electrical
resistance heating process in case of any
eventual system breakdown. If it is
necessary to use this function, press the
Electrical Support (3) ON/OFF button on the
command panel and the water will be heated
via electrical resistance.
5.9 System Decommissioning
At the end of the product lifetime,
decommissioning of the system should be
undertaken by an installer or suitable
qualified plumber and / or electrician (if
required). All materials used in this product
can be passed to your local material

Technical Support Notes:
- Melted Compressor fuse; start-up condenser capacity must be checked.
- Melted RES fuse; the possibility of a short-circuit must be verified (e.g. electrical resistance).
- Safety thermostat operational; electronic panel parameters must be checked.
8. MAINTENANCE PROCEDURES
Magnesium Anode
The anode must be removed in order to check it state.
If the magnesium anode is letting water pass it will be necessary change it. The period between
changing the anode is always dependent of the water quality in each location. In areas with raised
concentrations of soluble solids, the anode needs to be changed with less regularity, whereas in
situations with low concentration, the anode needs to be changed with greater regularity. Therefore
the magnesium anode state shallbe checked at least one time per year.
Pressure Reduction Valve Filter
The following procedure shall be done for periodic (maximum once every two years) cleaning of
the pressure reduction valve filter:
1. Close the passage of water from the network.
2. Turn in an anti-clockwise direction after relieving the spring’s tension.
3. Draw back the lever/handle.
4. Remove the filter and clean it.
