5. THERMODYNAMIC SOLAR PANEL INSTALLATION
Site selection
The choice of the installation site of the thermodynamic panel is a key factor in the final
performance of the unit. For this reason, we recommend following the indications to achieve
the best performance:
-South orientation is indeed the best to take the maximum advantage of solar radiation.
Panel may also have other orientations, but northerly orientation is the worst to receive
solar radiation.
-Inclination: The minimum inclination of the panel is 15º to ensure the correct evaporation
of the coolant. It is recommended to install the panel with an inclination between 45º and
90º.

-Orientation: It is possible to install the panel both in vertical and horizontal position
-Distances to ECOFLEX TD:
The maximum allowed distance from the panel to the ECOFLEX is 15 meters.
In the picture below is shown the dimensions of the panel:
Figure 5. Thermodynamic panel dimensions
Anchoring panel
Beside the panel, it is supplied a bag with anchoring elements that contains the following
pieces:
-6 x Aluminium support (L shape)
-6 x Screws M5
-12 x Nuts M5
-18 x Washer 5
When the panel is installed in
vertical position, the inlet and
outlet connection shall be
always at the bottom. (It is not
allowed to install the reverse)
If the panel is installed at
horizontal position, refrigerant
inlet pipe should be connected
into the bottom connection.

-18 x Sheet Metal Screws
-18 x Blocks M6
Anchor the panels using the lateral and front holes to the suitable surface.
6. PLACING ECOFLEX TD
The place where the system will be installed should allow an easy access to make maintenance
work or inspection.
Beside these factors, it is important to consider the following indications regards the installation
site:
-The system has been designed and manufactured for it indoors utilization.
-In case the system has to be placed outdoors, it must be protected against the adverse
weather conditions (direct solar radiation, rain, snow…)
-Try to place ECOFLEX as near as possible of the panels’ installation and near to the buffer
tank.
The equipment allows the installation on floor or on wall.
-Wall mounted: Ensure that the surface can support the total weight of the device. The
installer must fix the bracket to the wall and the insert the tabs into the corresponding
slot of the back of the ECOFLEX.
NOTE: It is recommended to install Silent blocks to avoid the transmission of vibration to the
wall.
-Floor mounted: Screw 4 leg into the holes of the bottom.
NOTE: It is recommended to install Silent blocks to avoid the transmission of vibration to the
floor.

If the equipment is to be installed in the wall, be aware that a minimum distance between the
water outlet of the tank and the outlet of ECOFLEX must be observed to ensure a good
functioning of the pump and the equipment.

7. CONNECTION BETWEEN ECOFLEX TD AND PANELS
a. Pipeline installation
First, measure the distance between Ecoflex and panels and cut the appropriate copper
pipe length. The diameter for each line is:
-Liquid line: 3/8 inch
-Gas line: ½ inch
b. Distributor/collector installation
Install a cooper tee to distribute and collect the refrigerant to/from the panels.
Its function is to ensure the homogeneous refrigerant flow in the whole panel installation.
The installer must weld a T connection of the following dimension:
-Gas line: 2 inlets 3/8 - 1 outlet 1/2
-Liquid line: 1 inlet 3/8 - 2 outlets 1/4
Figure 9. Panel connections
IMPORTANT: To ensure the same flow of refrigerant in every panel and consequently take
advantage of the evaporation surface entirely; you should install the same tube length from
the distributor to each panel. If a pipe is too long for the length require, it must be rolled up.

Figure 10. Ecoflex TD connections
IMPORTANT: It is recommended to weld pipelines by oxyacetylene welding.
Welding is a critical step in the installation and to do it well ensures that the system will run
properly along its useful life.
Only expert staff should make this step by using proper tools and high-quality materials.
c. Join refrigerant pipes to the panels and Ecoflex TD
Panels are supplied with two nuts for the inlet and outlet connection. The inlet to each panel
is 1/4 inch diameter. The installer must insert the nut into the copper pipe, flare the pipe

INSTALLATION AND USER MANUAL
ECOFLEX TD
14 V1REV4EN0822
and then use the nut to fit it. Repeat the procedure with the outlet connection using 3/8 inch
copper pipe.
The Ecoflex TD has two service valves with threaded connections:
-Inlet: 1/2 inch
-Outlet: 3/8 inch
The installer has to insert the nut into the copper pipe, flare the pipe and then use the nut
to fit it.
d. Nitrogen test and cleaning procedure
To check the tightness, introduce nitrogen by using the pressure gauge already installed
into load ports.
CAUTION: Never exceed a nitrogen load greater than 10 bars.
Use leaking detector fluid at every welding and even in panel’s connections to verify the
absence of leaks.
e. Vacuum
Connect the vacuum pipe to the pressure gauge to carry out a vacuum of the whole
installation.
f. Coolant filling
Open the load ports to fill the circuit with the refrigerant loaded into the system.

8. HYDRAULIC CONNECTION
The hydraulic connection depends on the existing buffer tank, if some type of connection for
the recirculation or coil is available.
The possible connections are detailed as follows:

Figure 13. ECOFLEX TD connection, buffer tank with inner coil.

INSTALLATION AND USER MANUAL
ECOFLEX TD
16 V1REV4EN0822
The installer must install the following components of the hydraulic circuit:
- ECOFLEX TD (1)
- Gate valve (2)
- Check Valve (3)
- Inclined filter (4)
- Expansion vessel (5)
- Safety valve (6)
- Storage tank (7)
- Pump (8)
- Pressure gauge (9)
- Red water inlet (E)
- DHW output (S)
- Inlet water filled coil (R)
- Probe connection (T)
Once the hydraulic connections are made, purge the circuit to remove the air from the
installation.
In addition, it is necessary to install electrolytic sleeves in the water connections to prevent
galvanic corrosion in the pipes.
IMPORTANT:
- The water pipes must be at least 22 mm in diameter to avoid excessive losses in the circuit
- If the unit is to be installed on the wall, its height must not exceed half the storage tank.
a. Pump connection
For the choice of the pump, it is necessary to consider the pressure drop of the installed
pipe as well as the accessories (elbows, filters, valves...). The following table shows the flow
rate to be circulated by the equipment and the pressure drop of the installed heat
exchanger:
Minimum flow, L/h
