4. INSTALLATION STEPS
Before starting the installation, check the availability of all the necessary components and tools:
-Copper tee for gas line: 2 inlets 3/8 - 1 outlet 1/2
-Liquid distributor (supplied): 1 inlet 3/8 - 2 outlets 1/4
-High- and low-pressure manometers
-Vacuum pump
-Scales
-Nitrogen bottle
-Refrigerant quality copper pipe
-Pipe-cutter
-Tube bender
-Pipe expander
-Welder
-Copper Rods (40% Silver)
-Insulating hose
-Drill
-Screwdriver
-Hydraulic installation components
-Electric installation components
Once it has been checked that it is available all the necessary components and tools, the
installer should follow the next steps:
1. Placing and anchoring panels
2. Joining and welding the refrigerant pipes
3. Placing the ECOHEAT TD
4. Joining and welding liquid and suction line between ECOHEAT TD and panel
5. Nitrogen pressure test (maximum 10 bar)
6. Vacuum
7. Filling refrigerant installation
8. Hydraulic installation
9. Electric installation

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 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 45º to ensure the correct
evaporation of the coolant. It is recommended to install the panel with an inclination
between 45º and 90º. The minimum inclination of the panel must be 5º to ensure the
correct evaporation of the fluid.
-Direction: The panel can be installed in a vertical or horizontal position. In the case of
horizontal installation, the refrigerant inlet will be made through the lower part of the
panel.
-Distance to the equipment: The maximum distance allowed from the panels to the
equipment is 15 meters (sum of the distances L1 + L2 + L3 + L4 in the following figure).

5.2. Anchoring panel
Beside the panel, it is supplied a bag with anchoring elements that contains the following
pieces:
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.

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 to make maintenance
work or inspection.
Air outlet of ECOHEAT is around 5-10 degrees below inlet temperature, so in case that the
exhaust air would not be ducted, the room temperature will be considerably reduced.
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. Install the
system in a dry, frost-free room at a minimum temperature of 5ºC.
-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: 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 the following accessories:
-Gas line: T connection with 2 connections of 3/8 inch (Panels) and 1 connection of
½ inch (Ecoheat)
-Liquid line: Liquid distributor with 2 connections of ¼ inch (Panels) and 1
connection of 3/8 inch (Ecoheat)
Install the distributor vertically, face upwards according to the picture:
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.

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 1/2 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 3/4 inch copper pipe.
Then, join the suction line that comes from the panel to the coolant inlet of ECOHEAT, and
the liquid line to the coolant outlet. The connections are threaded, if welding is needed,
weld by oxyacetylene welding.

IMPORTANT (Only when welding is needed):
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.
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.
