General and transport tips
The installation must only be carried out by qualified personnel. The entire information in these instructions is intended
exclusively for such qualified personnel. Only the supplied material should be used for the installation. Prior to starting
installation and operation of the solar collector system, please inform yourself about applicable local standards and regulations.
It is recommended that a carrying strap be used for transporting the collector. The collector must not be lifted direct at the tube
copper pipes or connection parts. There is a danger of damage. Avoid impacts and mechanical action on the collector, especially
on the solar glass and the pipe connections. If the aluminium tray collectors have a protective coating, this must be protected
from sunlight and removed just before installation.
Statics
The collectors must only be mounted on sufficiently load-bearing roof surfaces and substructures. It is imperative that the static
load bearing capacity of the roof or substructure is checked in terms of local and regional conditions prior to installation of the
collectors by the customer, if necessary with the involvement of a structural engineer. Particular attention should be paid to the
quality of the (timber) substructure in terms of the stability of the screw connections necessary for fastening the collectors. To
prevent damage to the roofing in the event of considerable loads, the use of metal reinforcements such as metal bricks is
recommended. The inspection of the entire collector structure according to DIN 1055 Parts 4 and 5 (EN 1991-1 Parts 4 and 5)
or as per the applicable country-specific regulations is particularly important in areas with heavy snowfall or in areas exposed
to high wind speeds. The assessment should also take into account any particular circumstances at the place of installation
(foehn wind, air jets or eddy formation etc.) which can lead to increased loads. Snow catchers are to be installed at a maximum
distance of 0.5m from the upper edge of the collector (the collector should not function as a snow catcher). It must be ensured
for the selection of the installation location that the maximum loads are neither exceeded by snow nor wind forces. Basically,
the collector arrays must be installed so that any possible accumulation of snow is prevented from reaching the collectors by
snow barriers (or by special forms of installation). The collectors may not be installed at the edge of the roof (e/10 marginal
zones on areas of roofing are to be complied with pursuant to EN 1991, but they must be at least 1m). The upper edge of the
collector may not project beyond the roof ridge.
Pitched roof mounting tips:The installation of a collector array is an intervention into a (existing) roof. Roof coverings such
as bricks, shingles and slates, especially converted and inhabited loft spaces or roofs with less than the minimum slope (with
regard to the covering) require building measures e.g. underroof membranes, as protection against water penetration caused
by wind pressure and driving snow.
Lightning protection / Equipotential bonding of the building
In accordance with the lightning protection standard ÖVE/ÖNORM EN 62305 Part 1-4 the collector array cannot be connected
to the building's lightning protection. A safety distance of at least 1 m must be maintained from any possible adjacent conducting
object. For installations on metal substructures at the installation site, generally qualified electricians must be consulted. To
carry out a building potential equalisation, the metal tubes of the solar circuit and all collector cases or fastenings must be
connected to the main potential equalisation bus by a qualified electrician in accordance with ÖVE/ÖNORM E 8001-1 or the
country-specific standards.
Connections
Depending on the design, the collectors must be connected with one another and/or the connection pipes using screw fittings
(1" internal/external thread) with flat-face sealing. Ensure correct placement of the flat gaskets. If it is not intended to use
flexible pipes as connecting elements, precautions must be taken to protect the connection pipes against temperature
fluctuations caused by heat expansion (expansion bends/flexible piping). In this case, no more than 6 collectors may be
connected in series. Larger collector arrays must be assembled with expansion bends or flexible members inserted in the links
(IMPORTANT: check the pump design). When tightening the connections, always apply counter-pressure with a wrench or
another spanner to prevent damage to the absorber. ATTENTION: Do not under any circumstances use pipe wrenches so as to
avoid damaging the glass edge.
Collector angle / General notes
The collector is suitable for angles between 15° (minimum) and 75° (maximum). Steps must be taken to ensure that water and
other contaminants such as dust, etc. are prevented from getting into the collector connections and ventilation holes.
Connecting support rails
If several support rails are mounted in series, these must be connected together with connectors above and below.
Warranty
Warranty claim only in conjunction with the supplier's original frost protection and correct installation, commissioning and
maintenance. Installation by qualified personnel with strict adherence to the instructions is a prerequisite for the justification of
claims. Note: Installing solar thermal pannels (collectors) near to coastal regions or in any other corrosive environment may
result in corrusion and corrosion of the absorber. Sonnenkraft doesn't take any responsibility or liability for such damages if
installed in such environment. If required, it is possible to contact us for a special solar panel which is designed and suitable for
such environment.
