réinitialise.

REMARQUE :

Si un AVERTISSEUR D’INCENDIE À
DISTANCE MANUEL est installé, tout
déplacement du ventilateur, quel qu’en soit
le motif, peut provoquer la décharge du
système Ansul®.

DANGER - NE PAS BLOQUER
L’ACCÈS À LA POIGNÉE DE
L’EXTINCTEUR !

DANGER :

RISQUE DE SUFFOCATION

“Ce ventilateur ne doit pas être utilisé avec
des appareils à gaz. Il n’absorbe pas les
produits de combustion. En l’absence de
sortie d’aération, les gaz de combustion
peuvent être mortels.”

AVERTISSEMENT :

RISQUE DE DÉCHARGE ÉLECTRIQUE

Toute intervention nécessitant d’accéder à des
composants électriques non isolés doit être
effectuée par un technicien agréé usine.

N’ouvrez AUCUN panneau d’accès nécessitant
