1 General information

This chapter details which technical rules and

regulations apply to this installation.

Lightning protection

If the building height (installation height) exceeds 20 m,

and there is no lightning conductor installed, ask your lo-

cal electrical contractor to connect the components on

the roof which conduct electricity with an electrical earth

cable of at least 16 mm2to the earth bonding.

Special measures regarding lightning protection are not

required for building heights (installation heights) of less

than 20 m.

Where there is a lightning conductor system installed,

ask your local electrical contractor to check the inclusion

of the solar heating system into the lightning protection

system.

3 Safety

This chapter details how the notes for the installation

instructions, as well as the general safety instuctions,

necessary for safe and truoble-free operation, are

arranged in this manual.

Safety and user notes, which specifically refer to the

installation, in the installation manual immerdiately

following the individual installation steps, are found here.

Carefully read the safety instructions before

commencing the installation.

Severe injury and even death, as well as material losses

and environmental damage, may follow if you ignore

safety instuctions.

3.1 Correct use

This installation set holds the thermal solar collectors,

which are installed on sloping roofs with a slope of 25°

to 60°. The collectors can be installed on corrugated and

sheet steel roofs with slopes of between 5° and 65°.

Operating conditions

Only erect the installation set on roofs whose

construction can support the weight. If necessary,

consult a structural engineer or a roofer.

The installation set is suitable for a max. standard snow

load of 2.0 kN/m² and an installation height of max, 20m.

Using appropriate accessories, the installation set can

be used for a max. standard snow load of 3.1 kN/m² and

a max. installation height of 100 m. See Chapter 5.8

"Installing profile rails".

The roof installation set must not be used for fixing any

other objects to the roof. The kit is intended exclusively

for the safe fixing of solar collectors.

3.3 Please observe these safety

instructions

WARNING!

RISK TO LIFE

through a fall or falling parts.

BEnsure you have the correct safety

equipment for working on roofs.

BTake appropriate action to prevent

accidents when working on roofs.

BWhilst working on the roof, take all

necessary precautions against a

possible fall.

BAlways wear your personal protective

clothing and safety equipment.

BAfter completing the installation, always

check the secure positioning of the

installed set and that of the collectors.

CAUTION!

RISK OF INJURY

Injury and operating faults can result from

making changes to the system

construction.

BNever change the system construction.

CAUTION!

RISK OF INJURY

Some parts may cause burns, if the

collector and installation materials are

exposed to solar radiation for longer

periods of time.

BAlways wear your personal protective

clothing and safety equipment.

BCover the collector (e.g. with a covering

sheet – available as an accessory

7739 300 399) and the installation

material during the installation as

protection against high temperatures

resulting from solar irradiation.

4 Before installation

4.1 General notes

Make yourself familiar with the on-site conditions and lo-

cal regulations before commencing the installation.

Check

Bthe delivery for completeness and perfect condition.

Bthe optimum arrangement of the solar collectors.

Take account of the direction of the sunlight (angle of

inclination, southerly direction). Avoid the shade of

high trees or structures and match the collector array

to the shape of the building (e.g. aligned with win-

dows, doors, etc.).

iUSER NOTE

It is recommended that the services of a

roofing company, who are experienced in

working on roofs and will be fully aware of

the risks of working at height are consid-

ered.

63043965.02-1.SD

CAUTION!

RISK OF INJURY

If the collector and its installation material

is left exposed to the sunlight for a long

period, the parts will become hot and may

cause burns.

BWear protective clothing.

BCover the collector (e.g. with

a covering sheet – available as an ac-

cessory 7739 300 399) and the instal-

lation material during the installation

as protection against high tempera-

tures resulting from solar irradiation.

iUSER NOTE

Only use OEM components and replace

any damaged or faulty parts immediately.

iUSER NOTE

Remove broken tiles, shingles or plates in

the area of the collectors and replace

them.
