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 TGSKR carrying
strap be used for transporting the collector. The collector must not be lifted direct at the tube copper pipes or connection parts. Ther is
a danger of damage. The transport protection used on the corners and edge of the glass must only be removed immediately before the
collector is inserted into the mounting system (see assembly step 7a). Avoid impacts and mechanical influences on the collector,
particularly on the solar glass, rear panel and the pipe connections.
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
The collectors are to be connected together using hydraulic connectors. The internal double seal is pre-lubricated in the factory to
facilitate fitting. Connectors are to be retained in their original packaging until use and protected from damage. The connector can still
be installed even if this lubricant is absent in the delivered state but it must not then under any circumstances be treated with different
lubricants. If the O-rings are damaged or soiled, the entire connector can no longer be used. Replacing the O-rings is not recommended
. Care should be taken to ensure that the connectors/connections are correctly fitted. Care should be taken with the connecting pipework
to ensure that appropriate precautions for compensating the heat expansion caused by temperature fluctuations are provided for
(expansion bends, flexible pipework). Recommended connecting diagrams are illustrated on pp. 28-29 along with the maximum number
of collectors per collector array. (ATTENTION: Inspection of pump configuration). 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). The collector connections and the ventilation openings
must be protected against the penetration of water as well as contamination such as dust etc. When installing the collector at an angle
to the horizontal of > 45 ° a bracket needs to be fitted at least prior to inserting the first collector in the support rails to prevent slippage
(1.9). This bracket should also be used when installing on very uneven roof structures. The antislip brackets can be removed again once
installation of the collectors has been completed.
Connecting the support rails
If several support rails are assembled in series, they have to be pushed fully home one inside the other. To this end, a connector is
already preassembled on the extension rails (TRP-ES). The assembled rails have to be fixed in position using the Allen key (see assembly
step 4). Care should be taken to ensure rotation at the correct angle.
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.
