5. THERMODYNAMIC SOLAR PANELS INSTALLATION
1. Site selection
The choice of the installation site of thermodynamic panels is a key factor in the final
performance of the heating module. For this reason, we recommend to follow the indications in
order to achieve the best performance:
- South orientation is indeed the best to take the maximum advantage of solar
radiation. Panels may also have other orientations, but northerly orientation is
the worst to receive solar radiation.
- Inclination: The minimum inclination of the panel is 15 º in order to ensure the
correct evaporation of the coolant. It is recommended to install the panel with
an inclination between 45º and 90 º.
- Orientation: It is possible to install the panel both in vertical or horizontal
position
When the panel is installed in vertical
position, always the inlet and outlet
connection has been at the bottom. (It is not
allow to install the reverse)
If the panel is installed at horizontal
position, it is recommended to install pair of
panels confronted for having less piping
towards the distributor.

IMPORTANT: If the panel is installed at horizontal position, refrigerant inlet pipe should be
connected into the bottom connection.
- Distances to heating module:
• The maximum allowed distance from the farthest panel to the
heating module is 15 meters.
• It is recommended not to exceed 20 meters of total length from
the heating module to the panels.
- Gap between panels: A minimum distance of 50 cm between panels should be
kept in order to have enough space to fit the pipes and collectors.
In the picture below is shown the dimensions of the panel:
2. Anchoring panels
Beside the panels is supplied a bag with anchoring elements that contain the following
pieces (per each panel):
- 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.

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.
Once panels are anchored, the next step consists on the installation of the liquid
distributor. Its function is to ensure the homogeneous refrigerant flow in the whole panel
installation.
Possible distributor scheme is shown in the next picture:
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 every panel. If a pipe is too long for the length require, it must be rolled up.
Panels are supplied with two nuts at 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.

make maintenance work or inspection. It is recommended to leave at least 400 mm of free space.

INSTALLATION AND USER MANUAL
HTM-24E
12 V0REV5ES1218
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 has to be placed outdoors, it must be protected against the
adverse weather conditions (direct solar radiation, rain, snow…)
- Since the Heating Module could cause vibrations and noise, it is recommended
to install it far away from bedrooms or resting places.
- Try to place the heating module as near as possible of the panels’ installation,
and also near to the buffer tank.
- Installer must install the supplied Silent blocks to avoid the transmission of
vibration.
7. CONNECTION BETWEEN HEATING MODULE AND PANELS
CAUTION: Heating Module is preload with a 20 kg of Nitrogen to ensure its tightness
during the transport. Liquid and suction connection are sealed, so before handle the module,
the installer must discharge the nitrogen through the charge ports located at the high and low
pressure line.
a. Check the tightness
Firstly, put the pressure gauge into the charge ports of the high pressure line and low
pressure line.

Then, check that the pressure at the module is not lower that 15 bar. If the pressure has
decreased, check the installation looking for leakages before continuing with the procedure.
b. Discharge Nitrogen
Discharge the nitrogen preload, opening the load ports until empty.
c. Cut the refrigerant pipes
Inlet and outlet refrigerant pipes are protected by insulating hoses. Firstly, remove the
isolation and through the use of pipe cuter, cut the ends of each tube.
d. Expand tubes
Use the tube expander for expanding the inlet and outlet refrigerant pipe in order to
proceed with the welding. Another option is to install a coupler between pipes.
e. Welding
Join the suction line that comes from the panels to the coolant inlet, and the liquid line to
the coolant outlet. Then weld it by the oxyacetylene welding.
f. Nitrogen load
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 soapy water at every welding and even in panel’s connections to verify the absence of leaks.
g. Vacuum
Connect the vacuum pipe to the pressure gauge to carry out a vacuum of the whole installation.
The recommended vacuum time is shown in the table below:

h. Coolant load
Depending on the model of the heating module, the installer has to fill a minimum load
of refrigerant according to the following table:

oad (kg)
HTM-24E
R407C
3,1
IMPORTANT: Refrigerant 407C, is a zeotropic mix that is composed by 3 different
components. For this reason, the refrigerant has to be in liquid state at the moment of the
loading to ensure the homogeneous charge of each compound.
Do the load always taking the refrigerant of the bottom of the recipient
Load the refrigerant ALWAYS WITH THE MODUEL SWITCH OFF and using the load port
located at the high pressure line, always in liquid state.
Once the initial load has been done, make hydraulic and electric installation.
When the heating module has been connected to the grid, switch on the grid voltage via
the line circuit breaker.
DO NOT ACTIVE TH SYSTEM BY THE THERMOSTAT: The heating module must be
switch off at least 10 minutes, while the crankcase heater is heating the compressor in order to
avoid any risk of liquid hammer in the compressor.
After this period, switch on the heating module using the thermostat key (or the switch)
and start the refrigerant load until achieve the appropriate load. For this issue, check the
ambient temperature and load refrigerant until the evaporation pressure (indicated in the
pressure gauge) match with the values at the table below:

8. HIDRAULIC CONNECTION
In Annex 1 is shown two recommended hydraulic schemes.
The installer must install the following components of the hydraulic circuit:
- Circulation pump
- Ball valves
- Lined Filter Strainer (Y Type)
- Pressure reducing valve
- Expansion vessel
- Safety valve
For the selection of the circulating pump it is needed to take into account the pressure
loss in pipes and accessories (pipe elbow, filter, valves).

Temperature probe
The installer has to install the temperature probe B1 in one of the following points:
- Inside the buffer tank
- Return water pipe
- If the buffer tank has a coil, in the return water pipe of the coil
9. ELECTRICAL CONNECTION
The electric switchboard is located in the front of the module. The installer has to make
the following connections:
1. Power supply:
Connect the system directly from the general control panel. The minimum wire section
and the characteristics of the circuit breaker that the installer has to install are shown in the
following table:
These data are calculated based on a maximum distance of 15m. In case of higher
distances contact with technical department for a new dimensioning.
2.
Circulator pump
Connect the circulator pump to the heating module. The system will control
automatically the operation of the pump when it is needed.
The connection is single-phase 230V/ 50 Hz. Pump must not exceed 5 A current.
In the Annex 2 and 3, are shown electric schemes. Connect the pump in the terminals 0-0.

3. Remote start/stop
There is the possibility of connecting an external switch to control the ON/ OFF of the
system. It is a zero-voltage contact, that must be connected to the terminals 7-7.
If the installer does not use an external switch, jumper connect the terminal blocks 7-7. In
this case, the module will be switch on through the thermostat (see section 10. Comminisioning).
