These products are intended for use in industrial compressed air and rail transport systems only. Do not use these products where pressures and temperatures can exceed those listed under »Technical features/data«.Before using these products with fluids other than those specified, for non-industrial applications, life-support systems or other applications not within published specifications, consult IMI NORGREN.

Through misuse, age, or malfunction, components used in fluid power systems can fail in various modes.

The system designer is warned to consider the failure modes of all component parts used in fluid power systems and to provide adequate safeguards to prevent personal injury or damage to equipment in the event of such failure.System designers must provide a warning to end users in the system instructional manual if protection against a failure mode cannot be adequately provided.System designers and end users are cautioned to review specificwarnings found in instruction sheets packed and shipped with these products.

Diese Produkte sind ausschließlich in Druckluft- und Bahnindustrie- systemen zu verwenden. Sie sind dort einzusetzen, wo die unter »Technische Merkmale/-Daten« aufgeführten Werte nicht überschritten werden. Berücksichtigen Sie bitte die entsprechende Katalogseite. Vor dem Einsatz der Produkte bei nicht industriellen Anwendungen, in lebenserhaltenden- oder anderen Systemen, die nicht in den veröffent-lichten Anleitungsunterlagen enthalten sind, wenden Sie sich bitte direkt an IMI NORGREN.Durch Missbrauch, Verschleiß oder Störungen können in Pneumatik-

systemen verwendete Komponenten auf verschiedene Arten versagen.Systemauslegern wird dringend empfohlen, die Störungsarten aller in Pneumatiksystemen verwendeten Komponententeile zu berück-sichtigen und ausreichende Sicherheitsvorkehrungen zu treffen, um Verletzungen von Personen sowie Beschädigungen der Geräte im Falle einer solchen Störung zu verhindern. Systemausleger sind verpflichtet, Sicherheitshinweise für den End-benutzer im Betriebshandbuch zu vermerken, wenn der Störungs-schutz nicht ausreichend gewährleistet ist.
