ent persons.

Note

Each competent person is qualified for specific

must only work on units if they have the re-

quired qualification.

When working on the units, the competent persons must

observe all applicable directives, standards, laws and other

regulations.

2.3 General safety information

2.3.1 Danger due to improper use

Vaillant auroTHERM VTK tube collectors are constructed

using state-of-the-art technology in accordance with the re-

cognised safety rules and regulations. Nevertheless, there

is still a risk of injury or death to the user or others or of

damage to the unit and other property in the event of im-

proper use or use for which it is not intended.

2.3.2 Risk of death due to improper fastening

systems

The collectors may fall due to improper fastening systems.

Only the combination of Vailllant collectors and Vaillant

fastening systems has been tested. This combination can

withstand the forces caused by additional wind and snow

loads.

▶ Only use the collector fastening systems that are ap-

proved by Vaillant.

2.3.3 Risk of death due to inadequate load-

bearing capacity of the roof

A roof with an insufficient load-bearing capacity may col-

lapse due to the additional load of the collectors.

Above all, additional wind and snow loads may result in

higher forces which could cause the roof to collapse.

▶ Ensure that a structural engineer has confirmed the roof

as suitable for collector installation.

▶ Only install the collectors on a roof that has adequate

load-bearing capacity.

2.3.4 Risk of death due to falling parts

Unsecured collectors can fall from the roof and present a

danger to persons.

▶ Block off the areas in the fall area below the place of

work to a sufficient extent so that persons cannot be

injured by falling objects.

▶ Indicate the working area, e.g. with information signs, in

accordance with the applicable regulations.

2.3.5 Risk of injury and material damage due to

incorrect maintenance and repairs

If maintenance or repair work is not carried out, or is car-

ried out incorrectly, this may result in injuries or in damage

to the solar plant.

▶ Ensure that only an approved competent person carries

out maintenance and repair work.
