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 dam-
age to the unit and other property in the event of improper
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 collapse
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 in-
jured 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 carried
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.
2.3.6
Risk of death due to inadequate fastening
of the collectors
Collectors can fall from their anchors if they are not properly
fastened on the roof. Collectors falling from the roof could
cause life-threatening accidents.
▶
Perform all work steps as described in this manual.
▶
Observe all safety precautions described in this manual.
▶
In addition, comply with all safety regulations that spe-
cifically apply in your region.
2.3.7
Risk of burns due to hot collector surfaces
In the event of solar radiation inside the units, collectors can
reach 300 °C. If you touch the collectors without protection,
you could burn yourself.
▶
Remove the sun protection film installed at the factory
only after the solar plant has been started up.
▶
Avoid performing installation and maintenance work un-
der direct sunlight.
