In accordance with the Machinery Directive 2006/42/EC, the valve is an incomplete
machine.
Everybody who executes works at or with the valve must have read and understood this
instruction and the safety instructions in it. Also the documents as drawings and additional
documentation must be observed. If instructions, recommendations and notices are not
followed, any possible warranty claim about the valve can be restricted or rejected.
