Installation and maintenance instructions auroFLOW plus 0020149486_04
▶
Check that there is no voltage.
1.3.4 Risk of death due to over-voltage
During a storm, components such as solar
lines and heating water pipes may carry a
charge from a lightning strike. Touching the
components may result in serious personal
injury.
▶
Earth the solar circuit to provide equipoten-
tial bonding and overvoltage protection.
▶
Secure earthing pipe clamps to the solar
lines.
▶
Connect the earthing pipe clamps to a
busbar using 16 mm
²
copper cable.
1.3.5 Risk of burns from components
through which solar fluid flows and
heating water pipes
In solar mode, components through which
solar fluid flows, such as collectors and solar
lines, as well as the heating water pipes,
reach extremely high temperatures. Touch-
ing these components may result in serious
personal injury.
Hot vapour may be emitted from the expan-
sion relief valve.
▶
Only touch these components if you have
first checked the temperature.
▶
To prevent injuries caused by hot parts,
carry out work, such as the installation and
replacement of collectors or collector parts,
when the weather is cloudy and overcast.
▶
Alternatively, if the weather is sunny, carry
out this work at the beginning or end of the
day or with the collector covered.
1.3.6 Danger due to error functions
Ensure that the solar system and heating in-
stallation are in a technically perfect condi-
tion.
▶
Ensure that no safety or monitoring
devices have been removed, bridged or
disabled.
▶
Immediately rectify any faults and damage
that may affect safety.
▶
At lengths of over 10 m, 230 V supply lines
must be laid separately from sensor or bus
lines.
1.3.7 Risk of material damage caused by
using an unsuitable tool
▶
Use the correct tool to tighten or loosen
screw connections.
1.3.8 Damage to the environment as a
result of leaking solar fluid
Leaking solar fluid may enter the groundwa-
ter and potentially contaminate drinking wa-
ter.
▶
Ensure that any solar fluid that is emitted
during installation and maintenance or
repair work is captured.
▶
Dispose of the solar fluid in an environ-
mentally friendly manner in accordance
with national regulations.
1.3.9 Product damage due to an
unsuitable installation site
The product can be damaged if it is installed
in an unsuitable room.
▶
Only install the product in a dry room that
is free of dust and corrosive or highly flam-
mable gases.
▶
In particular, when installing directly below
an uninsulated roof, care must be taken to
ensure that the air supply to the product is
guaranteed and that heat cannot build up
at the installation site.
–
In summer, the temperature at the in-
stallation site must not be considerably
higher than the outside temperature.
1.3.10 Risk of material damage caused by
frost
▶
Do not install the product in rooms prone
to frost.
1.3.11 Material damage due to additives in
the heating water
Unsuitable frost or corrosion protection
agents may damage seals and other com-
ponents of the heating circuit, and may
therefore also cause water leaks.
▶
Only add approved frost and corrosion
protection agents to the heating water.
