INTRODUCTION
1. Please read these instructions before installing or commissioning
the solar system.
2. Please leave these instructions with the user for later reference.
3. This solar thermal energy system for domestic hot water should only
be installed and handled by competent, authorised personnel.
During works, you must abide by:
•
The legal provisions on accident prevention.
•
Environmental legislation.
•
All occupational health and safety provisions in force.
• Specific EU safety regulations and the rules and regulations of the
individual country.
Keep the collector protected from the elements and in its origi-
nal packaging until installation.
To transport the collector, we recommend handling it in its packaging
with the aid of aluminium frames. Do not handle the collector by its
hydraulic connections. Protect the collector from knocks or other me-
chanical influences, especially the solar glass, rear of the collector and
hydraulic connections.
Cover the collector during installation until it is fully operatio-
nal, as this will prevent it from reaching high temperatures due
to solar radiation.
The installer is responsible for ensuring compliance with all
specific regulations in the individual country or region.
ORIENTATION AND TILT OF THE COLLECTOR
The best orientation of the solar collector is southward; if it is not pos-
sible to orient the collector in a southerly position, point it in a westerly
direction.
The best tilt angle will depend on when the system is used, which may
be:
a) Constant year-round demand: geographical latitude.
b) Demand mainly in the winter: geographical latitude +10°.
c) Demand essentially in the summer: geographical latitude -10°.
Avoid any shadows that could affect the solar collectors. Losses due to
orientation, tilt and possible shadows over the system must be kept at or
below the minimum levels permitted in the applicable regulations.mes ou
inférieures à la législation applicable.
GENERAL CONDITIONS OF INSTALLATION
All systems will have independent primary (with heat-transfer fluid) and
secondary circuits. Avoid mixing the different fluids.
They must all meet the regulations in force and specific legislation on
protection against electric shock.
Electrolytic sleeves must be installed between parts of different materials
to prevent galvanic coupling.
WORKING FLUID
The installer or designer will set the minimum allowed temperature
of the system. Components located outside must be able to withstand
this temperature without permanent damage. The system should be
protected against temperatures of 5°C below the lowest historical figure
recorded with a non-toxic chemical fluid designed for this purpose.
