3 Description
3.1 Operating principle
The short-wave solar radiation (sunlight) striking the solar panel is
converted into heat by the selective coating on the absorber. From
there it is transferred by heat conduction to the absorber pipe and
carried by the heat-transporting fluid to the calorifier. The solar-panel
fluid heats the calorifier by means of the energy absorbed from the
sun and cools down itself in the process.. The cooled heat-
transporting fluid then flows back to the solar panel in order to collect
more solar energy. An intelligent control system ensures that the
circulation system is only active when there is sufficient solar
radiation, thus optimising the collection of solar energy.

4 Installation
4.1 Regulations governing installation
4.1.1. All installation system
CAUTION
4The installation and maintenance of the appliance
must be carried out by a qualified professional in
compliance with the statutory texts of the codes of
conduct in force.
4Solar installations must be earthed to protect them
against lightning.
4Protection of the environment: Place a container of
sufficient volume under the drain pipe and the valve
discharge pipe.
4The installation should therefore not be flushed or filled when the
collectors are hot (in strong sunshine).
4The solar system must at all times be filled with : heat transporting
fluidTyfocor L or LS.
4.1.2. Roof-Surface Installation
CAUTION
Before installation, make sure that the framework is solid
and strong enough to comply with the static requirements.
4The roof-integral installation set is designed specifically as a
mounting system for the NEO 2.1 / SUN 211 flat solar panels and
may only be used in accordance with their building regulations
approval.
