Regulations (Directives, Laws, Standards) - Vaillant VWL Series Operating Instructions Manual

1.3.3 Risk of death due to lack of safety
devices
The basic diagrams included in this docu-
ment do not show all safety devices required
for correct installation.
▶ Install the necessary safety devices in the
installation.
▶ Observe the applicable national and inter-
national laws, standards and directives.
1.3.4 Risk of being burned or scalded by
hot components
▶ Only carry out work on these components
once they have cooled down.
1.3.5 Risk of material damage caused by
condensate inside the house
The lines between the heat pump and the
air/brine collector are cold, meaning that con-
densate can form on the lines in the house.
This may lead to material damage, for ex-
ample due to corrosion.
▶ Ensure that you do not damage the insula-
tion of the lines.
1.3.6 Risk of scalding from hot water
There is a risk of scalding at the hot water
draw-off points if the hot water temperatures
are greater than 60 °C. Young children and
elderly persons are particularly at risk, even
at lower temperatures.
▶ Select a moderate set target temperature.
▶ Inform the operator about the risk of scald-
ing when the Anti-legionella function is
switched on.
1.3.7 Risk of injury due to the heavy weight
of the product
▶ Make sure that the product is transported
by at least two people.
1.3.8 Material damage due to unsuitable
installation surface
The installation surface must be even and
have sufficient load-bearing capacity to sup-
port the operating weight of the product. An
uneven installation surface may cause leaks
in the product.
0020291544_01 Hydraulic Station Installation and maintenance instructions
There is a risk of death if the connections are
subject to leaks.
▶ Make sure that the product is positioned
flush against the installation surface.
▶ Ensure that the installation surface has
sufficient load-bearing capacity to bear the
operating weight of the product.
1.3.9 Risk of material damage due to
malfunctioning
Not rectifying faults, changing the safety
devices and failing to carry out maintenance
can cause malfunctioning and pose safety
risks during operation.
▶ Ensure that the heating installation is in a
technically perfect condition.
▶ Ensure that no safety or monitoring
devices have been removed, bridged or
disabled.
▶ Immediately eliminate any faults and dam-
age that may affect safety.
1.3.10 Material damage due to additives in
the heating water
Unsuitable antifreeze and corrosion inhibitors
may damage seals and other components
of the heating circuit, and may therefore also
cause water leaks.
▶ Only add approved antifreeze and corro-
sion inhibitors to the heating water.
1.3.11 Risk of material damage caused by
frost
▶ Do not install the product in rooms prone
to frost.
1.3.12 Risk of material damage caused by
using an unsuitable tool
▶ Use the correct tool.
1.4 Regulations (directives, laws,
standards)
▶ Observe the national regulations, stand-
ards, directives, ordinances and laws.
