Epreuve hydraulique / Hydrauliktest
Après le montage du corps, l’installateur doit effectuer un essai d’étanchéité eau à une pression égale à 2,3 fois
la pression de service soit 7,8 bar mini, pendant une durée de 10 minutes minimum. L’essai est effectué avec
de l’eau froide.
Nach der Montage des Kesselkörpers muss der Heizungsfachmann eine Dichtheitsprüfung durchführen mit
einem Druck von 1,3 mal dem Betriebsdruck und zwar 7,8 bar min. während 10 Minuten. Die Prüfung muss mit
kaltem Wasser durchgeführt werden.

Bien évacuer tout l’air du corps de chauffe
pour éviter tout risque d’éclatement de
celui-ci.
Kesselkörper gut lüften um ein Zerspringen
des Kesselkörpers zu vermeiden.
Maintien en pression pendant 10 minutes mini.
Une chute de pression signifie qu’il y a une fui-
te dans le corps de chaudière.
Der Druck muss mindestens 10 Minuten lang
gehalten werden.
Ein Druckabfall bedeutet eine Undichtheit im
Kesselkörper.
Après l’épreuve hydraulique, vidanger la chaudière
puis démonter toutes les pièces spécifiques mon-
tées sur les élément avant et arrière ayant servi à
la réaliser.
Nach dem Hydrauliktest den Heizkessel entleeren
und dann alle Bauteile demontieren, die speziell
zur Durchführung des Tests an das vordere und
hintere Glied montiert wurden.
