On-roof mounting: 

The tube collectors can be mounted at an angle of 
15° – 75°.
An installation angle of less than 15° is not permissible.

Flat roof installation:

The tube collectors can be installed on flat roof frames 
in the as-delivered condition with an angle of 30°, 45° 
or 60°.
An installation angle of less than 15° is not permissible.

3 Safety 

instructions

The following safety instructions, technical rules and ac-
cident prevention regulations must be observed when 
installing the flat collectors.

d

 Danger!

Risk of death from falls and falling objects!
Observe the national regulations for working at 
heights.

H

 Danger!

Danger of burning and scalding!
In case of solar irradiation inside the units, col-
lectors can reach 300 °C. Remove the sun pro-
tection film installed at the factory only after 
the solar energy system has been started up.

H

 Danger!

Danger of burning and scalding!
In case of solar irradiation inside the units, col-
lectors can reach 300 °C. 
Do not perform maintenance work under direct 
sunlight.

a

 Caution!

Collector damage!
A qualified engineer is required to install tube 
collectors in accordance with this installation 
manual. 
The installation should thus be performed only 
if a qualified engineer is available.

3.1 Technical 

Guidance

The system must be installed in accordance with all rel-
evant 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.

3.2 Related 

documents

Designers and installers should refer to current informa-
tion and standards. A useful reference would be the en-
ergy saving trust document CE 131 (this is downloadable 
from their web site at www.est.org.uk/housingbuildings) 
which lists relevant standards and other documents that 
you might refer to. This includes but is not limited to the 
following;

12977 (1-2-3) BS EN ISO 9488
The installation of the solar system must be in accord-
ance with the relevant requirements of Health and Safe-
ty Document No. 635 (The Electricity at Work Regula-
tions 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 Reg-
ulations (Scotland), The Building Regulations
(Northern Ireland) and the relevant recommendations of 
the following British Standards:
-  BS EN 806: Specification for installations inside build-

ings 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 sys-
tems.

Unvented hot water systems must comply with building 
regulation G section 3.

3.3 

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 man-
ner, 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 re-
quirements that can reasonably be foreseen to be
