Legislation, recommendations and maintenance
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 acknowled-
ged 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 techno-
logy 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. 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.
RECOMMENDATIONS
- 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.
- 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.
- Avoid installing the collector in shaded areas.
- The system must be inspected on completion of the work.
- A further inspection is recommended annually.
- 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.
- The collector must not be installed on an uneven roof surface.
- An anchor plug and bolt may be used to secure the collector on a suitable roof surface.
- Large arrays will require specialist piping, pump groups and design.
- A separate second array can be installed behind The first if necessary.
- The general recommended torque setting for nuts and bolts is 10Nm.
- If the roof is unsuitable for anchor plug and bolt, ballast may be used.
MAINTENANCE
It is recommended that the following checks are carried out on an annual basis:
1) Check the collector installation for any signs of damage or any build up of debris.
2) Check for any corrosion to the collector or the mounting system and repair if necessary.
3) Check the tightness of the fasteners. Where fasteners cannot be readily accessed, the overall
security of the collector installation may indicate whether problems exist.
4) Check the fittings and pipe work for any signs of fluid leakage or damage, including the con-
dition of the pipe insulation, and repair if necessary. Check inside the building for any evidence
of leaks.
5) Examine the roof tiles around the collector installation for any damage or deterioration, and
repair if necessary.
6 )Check for any foliage growth that may cause shading of the collectors.
7) Where applicable, check the condition of any ballast used to secure the system.
8) In areas where there may be a build up of dirt on the collector, only nonabrasive cleaning
materials and methods should be used to clean the collectors and mounting system components.
