1.0 Legislation

Please note the following instructions regarding laws, regulations and technical rules.

When setting up solar energy installations, the laws and regulations at local, state, European and international level that apply to the country in question must be observed. Generally acknowledged technical regulations apply; these are usually formulated in the form of standards, guidelines, provisions, regulations and technical rules laid down by local and national bodies, energy supply companies, trade organisations and technical committees in the relevant fields. The installation of solar units may require improved rain resistance with regard to roof, wall and sealing technology and this must be taken into account accordingly. To meet regulations for the prevention of accidents, it may be necessary to use safety equipment (straps, scaffolding, supports, etc.). Such safety equipment is not supplied and must be ordered separately. Installation must only be carried out by technically qualified and authorised personnel with a recognised qualification (verified by a state or national body) in the relevant technical area.

Use a safety harness when working at height. The structure of the roof must be assessed for its suitability prior to commencing work. Consult a Structural Engineer if you are unsure of the collector’s siting. Loading due to snow may exceed the capability of the property’s structure. Wind loads may cause excess forces on the structure and cause damage. The Installer is responsible for the suitability of the site and its sub-structure. An anchor plug and bolt may be used to secure the collector on a suitable roof surface. If the roof is unsuitable for anchor plug and bolt, ballast may be used. A ballast tray is available if required. The collector should be sited to avoid damage from falling debris and vandalism. All pipe work within this installation must be Earth bonded. In exposed areas, the collector must be protected against the risk of lightning. It is recommended that a minimum of 2 people are used to lift this product. The collector must not be lifted by its pipe connections. Ensure all hydraulic connections are securely fixed and are free of leaks. The system must be inspected on completion of the work. A further inspection is recommended annually. Avoid installing the collector in shaded areas. The general recommended torque setting for nuts and bolts is 10Nm. A separate second array can be installed behind the first if necessary. Large arrays will require specialist piping, pump groups and design. The collector must not be installed on an uneven roof surface. Do not apply excessive force when installing the collector. Hot, exposed surfaces that can be touched must be insulated to protect against injury. Lubrication is not required for the ‘O’ ring connections.
