3. SPECIFICATIONS
3.1. Running Principle
The thermodynamic solar system Eco-Nomic is based upon the refrigeration working principle by
compression –Thermodynamic principle of Carnot –which we designate by Thermodynamic Solar
Systems: solar panel and heat-pump.
The solar panel it’s the main component, shall be placed outside. Is also responsible for collecting
the energy from:
Diffuse and direct solar radiation
Air, by natural convection
The wind effect (almost always available)
Rain
The temperature gradient between the external agents mentioned above and the fluid inside the
solar panel, makes the fluid to evaporate on its inside. The absence of glass in the solar panel allows
for an increased thermal heat exchange by convection.
After circulating in the solar panel, the fluid is aspirated by the system’s mechanical component, the
compressor, which will increase its temperature and pressure; then the temperature is transferred
to the water circuit by a heat exchanger.
Before the fluid returns to the solar panel it’s pressure and temperature are reduced by passing thru
a expansion valve, completing the cycle.
The easy way we combine technology with a law of Nature (change of state of a fluid), demonstrates
the true potential of the Thermodynamic Solar System –ECO-NOMIC.

3.4. Safety and Control Devices
3.4.1. Safety Thermostat
The safety thermostat is set by the supplier to ensure that the water temperature in the storage
water heater does not exceed the standard value. Should the temperature exceed this value, the
thermostat switches off the support resistance. Switching on is done manually by qualified staff, after
analysing the reasons for the switch off.
3.4.2. Protection against corrosion
The hot water cylinder in this equipment is made of stainless steel AISI444.
Besides being resistant to corrosion, the storage water heater has in addition a magnesium anode
that should be checked periodically according to information by the installer.
3.4.3. Expansion Vessel (not supplied)
The expansion vessel is a device whose purpose is to compensate for the increase in water volume
due to temperature rise and to reduce the consequence of any water hammer effect.
Installing this device is a recommended procedure for a correct installation of the
equipment.
Installing this device is the responsibility of the installer.
As a general rule it is installed in the cold water pipe.
3.4.4. Safety Group
The safety device allows the system to be protected against anomaly situations: cold water supply,
hot water flowing back, emptying the storage water heater and high pressure. The valve is calibrated
to activate at 0.7 MPa.
In order to drain the water in the storage water heater, you should close the supply valve and open
the discharge valve.
The safety valve discharge pipe must be open into the atmosphere, driven to the sink because the
valve may drip or even discharge water.

ECO-NOMIC
TECHNICAL MANUAL
15
The safety valve must be opened regularly to remove impurities and check that it is not blocked. The
discharge pipe must be installed in a vertical position and not placed in a freezing location.
WARNING
DANGER
The installation of the safety group must take into consideration the right direction of
the hydraulic flow.
The right direction is represented by an arrow on the component. An incorrect
installation poses a danger to people and to the equipment.
3.4.5. Pressure Reducing Valve (not supplied)
The pressure reducing valve must always be installed upstream from the safety device, and ready to
activate in situations when the pressure in the circuit exceeds 3 bar. This valve comes with a pressure
gauge.
WARNING
DANGER
The installation of the pressure reducing valve must take into consideration the right
direction of the hydraulic flow.
The right direction is represented by an arrow on the component. An incorrect
installation poses a danger to people and to the equipment.

4.3. Refrigerant connections
4.4. Hydraulic connections
4.5. Electric connections
4.1. Thermodynamic Solar Panel Installation
The nature of the site and the inclination angle where the panels are installed are important factors
to consider. In order to benefit the most from the sunlight exposure, the panels should have a pitch
between 10oand 85orelative to the horizontal plane, and preferably oriented to the south (on the
north hemisphere).
The panel already comes with 6 holes for M8 in the lateral bends. The distance between holes in the
place where the panel rests should coincide with the holes made in the panel.
WARNING
Fixation in at least 6 points (3 points at the top and 3 points at the bottom) is
mandatory!
The lack of at least one of these points may cause deformities in the panel and, in
some cases, may cause the panel to move away from the place of installation.

ECO-NOMIC
TECHNICAL MANUAL
16
Attachment of brackets
The system has 3 small brackets (side A) and 3 large brackets (side B) that should be attached as
shown in the picture. The desired inclination of the panel should be adjusted.
The profile should be attached to the base (e.g. roof tile) through a plastic bushing and a self-thread
M6 bolt which have been supplied.
The attachment of the panel to the brackets is done through M6 screws, its nuts and washers.
The panel’s packaging has a marking that serves as a guide bar for the holes drilled at the base. This
marking follows the diagram below:
