1 General Safety Notes
1.1 Symbols
The following symbols are used throughout these instruc-
tions and must be adhered to:
DANGER of possibly serious personal injury
WARNING against material damage.
NOTE as additional information
1.2 Norms and Regulations
The standards and regulations applicable at the instal-
lation location must be adhered to. In absence of other
regulations we recommend to follow the following norms:
Thermal Solar Systems and Components
●EN 12976 and EN V 12977
Electrical Work, Potential Equalization, Lightning
Protection
●DIN EN 62305
●VDE 0185 part 305
●DIN VDE 0100 part 540
●VDE 190
●DIN 18382
(Other regulations may apply, depending on your region,
country or territory.)
Especially the pipes in the lower parts of the building
must be connected electrically conductive, conforming to
standards. The collector installation must be profession-
ally integrated with an existing or new lightning protection
system.
Snow and Wind Loads
Comply with local regulations and norms related to snow
and wind loads, within the EU to EN 1991-1-4 (Wind Ac-
tions) and EN 1991-1-3 (Snow Loads). If you have ques-
tions related to structural conditions and planning, please
contact our technical department for information. We offer
comprehensive planning support on a project base.
Work on Roofs
Make sure to observe country and territory regulations re-
lated to roof works and roof sealing standards as well as
professional codes for plumbing work.
The installation process must reflect the on-site condi-
tions as well as applicable rules, regulations and accident
prevention procedures. Installers must be qualified and -
where applicable - licensed to work on roofs.
1.3 Qualification of the Installer
Setup, installation and proper commissioning of the solar
installation must be carried out by authorized profession-
als. Non-compliance renders the warranty void.
1.4 Intended Use and Application
Proper Outdoor Storage of Collectors
Remove protective film, and lay down collectors with glass
pane up.Avoid direct ground contact (e.g. underlay square
timber). Avoid scratches on glass panes by using spacers
between collectors (e.g. wooden laths). When leaning col-
lectors against walls or similar, use a minimum inclination
of 15° and apply spacers. Do not use cardboard as under-
liner. If incorrectly stored, humidity can enter the collec-
tors through the air vents. Storing collectors in plastic film
package can damage the glass surface (see figure 2).
Scope and Limitations of Application
The collector is intended for the application in solar ther-
mal installations for hot water preparation and space heat-
ing support. As operating mediums water (attention – risk
of freezing!) or an appropriate water-glycol mixture can
be used in a closed circuit. Operational conditions under-
running the dew point within the collector for prolonged
periods are not permitted! This can occur for example,
when collectors are integrated in the brine circuit of a heat
pump.
Assure Proper Roofing structure
For in-roof installations the section behind the collectors
hast to be protected against rising moisture and trapped
air. In the area of the collector field sufficient back-side
ventilation of the roof must be assured (see „3. Installa-
tion Field.“)
Overheat Protection
For roof heating centrals and when 4 or more EURO col-
lectors with anti reflective glass are installed vertically, the
“Technical Information Solar Thermal Systems – Setup,
Commissioning and Maintenance” must be followed to
avoid damage to the solar circuit.
Preventing frost Damage
After pressure testing and flushing, collectors cannot be
completely emptied. Make sure that no pure water re-
mains in collector during risk of frost!
Empty Collector on Roof
After being installed on the roof, unfilled collectors should
not be exposed to the sun for more than a few days. Other-
wise thermal stress on gaskets can result in damage. Alter-
natively postpone the installation of gaskets to just before
filling the solar circuit.
Maintenance
For maintenance notes and additional information about
setup and operation of the collector field, please refer to
the technical information “Solar Thermal Systems”.

1.5 Pre Installation Notes
●Risk of burns at collector connections as soon as uncov-
ered collector is exposed to the sun (figure 3).
●Danger of open injuries when working with sharp
edged metal sheets and components!
●Remove protective plastic caps from connections be-
fore collector is exposed to the sun. Risk of melting and
damage to absorber!
●Remove glass protection PE-LD film before commenc-
ing installation work! (figure 4).
1.6 Recycling Note
At the end of the long operational lifetime, the valuable
materials of the installation should be recycled in an en-
vironmentally sound manner. If recycling is not possible,
Wagner & Co will take the scrap material back.
Figure 2 Do not expose collector covered with protective film to rain.
Figure 3 Collector connections heat up during solar irradiation.
Figure 4 Remove glass protection film before installing collector!

3 Prepare Installation Field
To warrant permanence of the installation, various prereq-
uisites have to be fulfilled:
●A waterproof and diffusion reducing foil with at least 24
mm counter-lathing must be present to assure proper
ventilation. If proper backside ventilation cannot be
provided via ridge and eaves, a venting tile must be in-
stalled, approx. 90 cm above and below the collector
field (see also figure 8, lower part).
●Keep a distance of at least 1m between collectors and
roof components or extensions like vents, turrets, chim-
neys or roof windows that emit humid air. Otherwise ad-
ditional humidity might enter the collector vents at the
collector frame.
●There should be at least 2 rows of roof tiles above and
below the collector field.
●The roof tile row above the collector should extend for
at least 100 mm over the upper flashing sheets. If re-
quired, the roof tiles have to be shortened.
●For best results properly utilize the flexible space below
the collector (distance to lower tile row between 60 and
130 mm).
Figure 7 Dimensions of installation field and positions of installation laths in mm. Choose lath thickness based upon existing laths.
Additionally required laths are coloured grey (5 pieces); lath length = A (width of installation field).
Installation field width = n x collector width + n x 5 mm (distance betw. collectors) + 2 x 15 mm (distance from edge)
Leave the existing roof battens in place as supporting
construction, and affix the additional laths required for the
installation according to the dimensions given in figure 7
and 8.
Ideally determine the width of the collector field in such a
way that on one side the spacing between collectors and
roofing is approx 15 mm. On the other side cut tiles to fit.
