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.

4.1 Regulations governing installation
4.1.1. All installation system
CAUTION
4 The 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.
4 Solar installations must be earthed to protect them
against lightning.
4 Protection of the environment: Place a container of
sufficient volume under the drain pipe and the valve
discharge pipe.
4 The installation should therefore not be flushed or filled when the
collectors are hot (in strong sunshine).
4 The 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.
4 The 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.

tiles. If the roof in which the panels are to be fitted has particularly
high roof tiles, please consult your specialist advisor.

effects of snow and wind on buildings.
CAUTION
If the assembly's supporting frame is not screwed to the
building, it must be weighted down according to the
technical guidance. Kerb stones (100 x 250 x 080), for
example, are suitable for weighting down. Stones must be
slid in and set in between the T frames. Position the ballast
stones before the finally attaching the inner screws and
the cross.
At no time should the maximum authorised load be
exceeded. If necessary, a structural engineer should be
consulted before commencing work.

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.

Stainless steel roof anchor for flat tiles
EG 315 (4 pieces)
EG 316 (6 pieces)
These roof anchors are attached directly to the roof rafters (rafter-
mounted anchors). Their slim design normally allows two roof
anchors to be fixed to one rafter.
n
Stainless steel roof anchor for corrugated rooves
EG 317 (4 pieces)
EG 318 (6 pieces)
On corrugated rooves (fibrecement, asbestos, etc.) these roof
anchors are screwed to the roof rafters through the corrugated sheets
(rafter-mounted anchors). They are fixed by coach bolts (not
supplied with the roof anchors as they vary depending on the roofing
manufacturer).
n
Stainless steel roof anchor for slate
EG 319 (4 pieces)
EG 320 (6 pieces)
These roof anchors are screwed to the rafters through the boarding
(rafter-mounted anchors). The roof anchor then has to be covered
in the normal way.
