5. THERMODYNAMIC SOLAR PANEL INSTALLATION
5.1. 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 in order
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 in order 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 ECOHEAT TD:
The maximum allowed distance from the panel to the ECOHEAT TD is 10 meters.
In the picture below is shown the dimensions of the panel:
When the panel is installed in vertical
position, always the inlet and outlet
connection has been 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.

5.2. 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
-18 x Sheet Metal Screws
-18 x Blocks M6
Anchor the panels using the lateral and front holes to the suitable surface.
6. PLACING ECOHEAT
The place where the system will be installed should allow an easy access in order to make
maintenance work or inspection.
Beside these factors, it is important to take into account the following indications regards the
installation site:
-The system has been designed and manufactured for it indoors utilization. In case the
system must be placed outdoors, it must be protected against the adverse weather
conditions (direct solar radiation, rain, snow…)
-Try to place ECOHEAT TD as near as possible of the panels and near to the buffer tank.
-Installer must install the supplied Silent blocks to avoid the transmission of vibration.

7. CONNECTION BETWEEN ECOHEAT TD AND PANELS
a. Pipeline installation
First, measure the distance between Ecoheat and Panels and cut the appropriate copper
pipe length. The diameter for each line is:
-Liquid line: 3/8 inch
-Gas line: 1/2 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
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.

ECOHEAT TD
10 V0REV1EN0422
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 Ecoheat
Panels are supplied with two nuts for the inlet and outlet connection. The inlet to each panel
is 1/4 inch diameter. The installer has to insert the nut into the copper pipe, flare the pipe
and then use the nut to fit it. Repeat the procedure with the outlet connection using 3/8 inch
copper pipe.
The Ecoheat 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
In order 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. HIDRAULIC CONNECTION
The hydraulic connections are shown in the following scheme:
The installer must install the following components of the hydraulic circuit shown in the scheme.
-Cold water inlet (1)
-Ball valves (2)
-Pressure reducing valve (3)
-Non-return valve (4)
-Lined Filter Strainer (Y Type) (5)
