2 Safety instructions
2.1 Technical Guidance
The system must be installed in accordance with all relevant and applicable national regulations, and must be
installed to suit site conditions.
Observe all national regulations, including:
- Working at Heights Regulations 2005
- Health and Safety at Work Act 1974
- Electricity at Work Regulations 1989
- IEE Wiring Regulations BS 7671
- Lightning protection requirements
- Equipotential bonding of electrical installations.
2.2 Related documents
The installation of the solar system must be in accordance with the relevant requirements of Health and
Safety Document No. 635 (The Electricity at Work
Regulations 1989), BS7671 (IEE Wiring Regulations) and
the Water Supply (Water Fitting) Regulations 1999, or
The Water Bylaws 2000 (Scotland). It should also be in
accordance with the relevant requirements of the Local
Authority, Building Regulations, The Building Regulations
(Scotland), The Building Regulations (Northern Ireland)
and the relevant recommendations of the following
British Standards:
- BS EN 806: Specification for installations inside buildings conveying water for human consumption.
– BS 6700: Services supplying water for domestic use
within buildings and their curtilages.
- BS. 5449 Forced circulation hot water central heating
systems for domestic premises.
Note: only up to 45 kW.
- BS. 6880 Low temperature hot water heating systems
of output greater than 45 kW.
Part 1 Fundamental and design considerations.
Part 2 Selection of equipment.
Part 3 Installation, commissioning and maintenance.
– BS 6114: Expansion vessels using an internal dia-
phragm for unvented hot water supply systems.
- BS. 4814 Specification for: Expansion vessels using an
internal diaphragm, for sealed hot water heating systems.
Unvented hot water systems must comply with building

2.3 Regulations for the prevention of accidents
When carrying out works such as solar installation work
it is necessary to do so in a safe and workman like manner, taking due care of any aspects of the works that
could result in injuries to person in or about the building
as well as workers, passers by and the general public at
large. To that end these works must conform, but not be
limited to, the current regulations in force such as the
following
Health and Safety at Work act 1974
Work at Height Regulations 2005.
Electricity at Work Regulations 1989
All necessary Building Regulations.
Work should be preceded by a risk assessment covering
all aspects of health and safety risks, or training requirements that can reasonably be foreseen to be associated
with the work. All scaffolding in the UK, other than prefabricated (zip-up) scaffold towers, must be designed
and constructed by a vetted contractor, and have
suitable kick boards, hand rails and where appropriate
netting. Areas around the scaffolding should be zoned
off and marked with suitable warning signs to a suitable
distance to protect persons from falling objects.
Workers should have available and use personal protective equipment as necessary. This would include equipment such as fall protection systems, safety gloves, goggles, dust masks as well as any specialised equipment
that may be in use such as lifting and handling equipment.
The completed works shall comply with all necessary
BS EN Standards and Codes of practice as well as
Building control or planning requirements and be confirmed where necessary by notification to building control
or the appropriate competence based notification body.
2.4 Intended use

applications shall be considered as improper use. The
manufacturer/supplier shall not be responsible for any
damages resulting from such improper use. The user
