General safety information

1.2.1 Risk of death due to improper
fastening systems
The collectors may fall if fastening systems
are incorrectly fitted.
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 approved by Vaillant.
1.2.2 Risk of death due to inadequate
load-bearing capacity of the roof
A roof with an insufficient load-bearing capa-
city 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 con-
firmed the roof as suitable for collector in-
stallation.
▶ Only install the collectors on a roof that
has adequate load-bearing capacity.

1.2.3 Risk of death due to falling parts
Unsecured collectors can fall from the roof
and create a possible danger to people.
▶ Block off the areas in the fall area below
the place of work to a sufficient extent so
that people cannot be injured by falling
objects.
▶ Indicate the working area, e.g. with inform-
ation signs, in accordance with the applic-
able regulations.
1.2.4 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 res-
ult in injuries or in damage to the solar plant.
▶ Ensure that only an approved competent
person carries out maintenance and repair
work.
1.2.5 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. Col-
lectors 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 regula-
tions that specifically apply in your region.
1.2.6 Risk of burns due to hot collector
surfaces
In the event of solar radiation inside the units,
collectors can reach 200 °C. If you touch the
collectors without protection, you could burn
yourself.
▶ If a sun protection film has been attached
to the collectors in the factory, remove it
only after the solar plant has been started
up.
▶ Avoid performing installation and mainten-
ance work under direct sunlight.
▶ Cover the collectors before starting work.
▶ You should preferably perform the work in
the morning.
