Solar Thermal - Installation and Servicing
5 ASSEMBLY INSTRUCTIONS
General and Transport Instructions
The mounting system is suitable for tiled roofs only. Installation must only be carried out by qualied personnel. The entire
information in these instructions is intended exclusively for such qualied 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 the applicable
local standards and regulations. The use of a carrying strap is recommended for transporting the collector. The collector must
not be lifted at the connections or on the threading. Avoid impacts and mechanical inuences on the collector, in particular on the
solar glass, the rear panel and pipe connections.
Statics - tiled roofs
The collectors may only be mounted on sufciently 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 through 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. The
checking of the entire collector structure by the customer as per DIN 1055 part 4 and 5 or as per the applicable country-specic
regulations is particularly important in areas with heavy snowfall (note: 1 m³ powder snow ~ 60 kg / 1 m³ wet snow ~ 200 kg) 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. When selecting the installation site
it should be ensured that the maximum load is not exceeded either by snow or wind forces. As a rule, collector arrays must be
installed such that any possible collection of snow is prevented from reaching the collectors by snow barriers (or through special
forms of installation). The distance to roof ridges/edges must be at least 1 m.
Note: Installing a collector array signies an intervention into an (existing) roof. Roof coverings, e.g. tiles, shingle and slate,
especially in the case of converted and inhabited loft spaces or roofs with less than the minimum slope (with regards to the
covering) require additional measures by the customer, e.g. sarking membranes, as security 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 qualied 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 qualied electrician in accordance with ÖVE/ÖNORM E 8001-1 or the country-specic
standards.
Connections
Depending on the design, the collectors must be connected with one another and/or the connection pipes using screw
ttings (1” internal/external thread) with at-face sealing. Ensure correct placement of the at gaskets. If exible pipes are
not used as connectors, precautions must be taken to protect the connection pipes against temperature uctuations caused
by heat expansion, e.g. expansion bends and exible piping (see Connecting the collectors to one another/Operational
recommendations). Larger collector arrays must be assembled with expansion bends or exible members inserted in the links.
(IMPORTANT: check the pump design). When tightening the union nuts, always balance (counter) the torque with a pipe wrench
or another spanner to prevent damage to the absorber.
Collector inclination / General notes
The collector is suitable for angles between 20° (minimum) and 65° (maximum). The collector must be installed so that rear
ventilation for preventing the diffusion of moisture in the collector is guaranteed. The collector connections and the ventilation
openings must be protected against the penetration of water as well as contamination such as dust etc.
Cleaning
Clean the water courses of the sheet metal edging at least once per year (or more often if required).
Legal guarantee
Legal guarantee claims can only be made if the supplier’s own antifreeze has been used and maintenance has been carried out
correctly. Installation by qualied personnel with absolute adherence to the instructions is a prerequisite for the justication of
claims.
