Danger to life from carbon monoxide

Carbon monoxide (CO) is a poisonous gas, which arises during the incomplete

combustion of fossil fuels such as oil, gas, or solid fuels.

Dangers arise if CO escapes from the heating system due to a fault or a leak and

collects unnoticed in enclosed spaces.

You can neither see, taste nor smell CO.

The device may not prevent chronic effects of CO exposure. The product will not

completely safeguard individuals at special risk.

1 Allgemeine Sicherheitshinweise

Alle Anweisungen müssen befolgt werden. Bei Nichtbeachten sind Sachschäden und

mitunter lebensgefährdende Personenschäden möglich.

Sicherheit elektrischer Geräte für den Hausgebrauch und ähnliche Zwecke

Zur Vermeidung von Gefährdungen durch elektrische Geräte gelten entsprechend

EN 60335-1 folgende Vorgaben:

"Dieses Gerät kannvon Kindern ab 8 Jahren und darüber sowie von Personen mit

eingeschränkten physischen, sensorischen oder mentalen Fähigkeiten oder Mangel

an Erfahrung und Wissen benutzt werden, wenn sie beaufsichtigt oder bezüglich des

sicheren Gebrauchs des Gerätes unterwiesen wurden sowie die daraus resultieren-

den Gefahren verstehen. Kinder dürfen nicht mit dem Gerät spielen. Reinigung und

Wartung dürfen nicht von Kindern ohne Beaufsichtigung durchgeführt werden."

Lebensgefahr durch Kohlenmonoxid

Kohlenmonoxid (CO) ist ein giftiges Gas, das unter anderem bei der unvollständigen

Verbrennung fossiler Brennstoffe, z. B. Öl, Gas oder Festbrennstoffe, entsteht.

Wenn Kohlenmonoxid aufgrund einer Störung oder einer Undichtigkeit aus der Hei-

zungsanlage austritt und sich unbemerkt in Innenräumen ansammelt, besteht Ge-

fahr.

Kohlenmonoxid ist geruch- und geschmacklos sowie nicht sichtbar.

Das Gerät ist nicht geeignet, chronische Auswirkungen einer CO-Exposition zu ver-

hindern. Es dient nicht zum vollständigen Schutz von Personen mit besonderen Risi-

ken.

Heizungsanlage regelmäßig durch einen zugelassenen Fachbetrieb inspizieren und

warten lassen.
