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 heat­transporting 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.

4.2.2. Anchorage fittings for roof mounting

The roof anchors are not included in the roof-surface
installation set and must be ordered separately.

CAUTION

Before installation, make sure that the framework is solid
and strong enough to comply with the static requirements.

There are different types of roof anchor available:

4 Aluminium roof anchors for assembly independent of the

chevrons.

4 Rafter-mounted anchors.

4 Hooks to be fitted to the roof covering.

In the first case, additional mounting battens have to be added to the
roof structure. In order to fit the mounting battens to the framework of
a finished roof, the roof tiles covering the entire length of the mounting
battens have to be moved out of the way. The roof anchors are then
located on the battens and fixed.
With the rafter-mounted type, only individual tiles above the fixing
points on the rafters have to be removed. The roof anchors are
screwed to the rafters thus exposed. Afterwards, the tiles are replaced
and the roof is immediately waterproof again. The installation of the
panel-mounting system can start.
If installing on metal rooves, the roof anchors must be ordered from
the manufacturer of the roof system concerned.
The hoses of the solar-panel connection sets can be passed through
the roof by feeding them through a vented roof tile.

4.9 Filling the system

CAUTION

4 Do not fill / rinse a hot solar collector. Risk of being

burnt.

4 Before the filling of the installation, to check the

preload of the expansion vessel according to the
static height (Preload = static Height/10 + 0.3 bar).

4 check the connection to the series of collectors and

the collector sensor connection.

4 Since propylene glycol leaks much more easily than

water, check all connections and gaskets for leaks
after a few hours of operation at working pressure.

Following installation of the solar panels and hydraulic connection of
the panels and piping, the system can undergo pressure tests and be
filled. When doing so, the thermal conditions and the particular
features of the installation must be taken into account. For that
reason, the system may only be filled, commissioned and maintained
by a suitably authorised technician.
Bring the pressure in the primary solar circuit up to the 2 bar working
pressure by topping up if necessary with heat transfer fluid.

To prevent damage to the collectors and their connections by frost
and corrosion, it is essential that a high quality heat transporting fluid
be used to fill the solar installation. If the recommended ready-mixed
fluid is used (Tyfocor L / LS) the system will be adequately protected
at temperatures down to approx. -24 °C.

To prevent any damage of the system, pressure tests should only
be carried out with the heat-transporting fluid used later on.
