Schmalz accepts no liability for damage resulting from non-intended use of the mini valve terminal.
In particular, the following types of use are considered non-intended use:
• Use in potentially explosive atmospheres
• Use in medical applications
• Lifting people or animals
• Evacuation of objects that are in danger of imploding
2.3Personnel Qualifications
Unqualified personnel cannot recognize dangers and are therefore exposed to higher risks!
