Beware of Agitator in operation can produce sound levels in excess of 85dB(A).
Never operate continuously within 20% of critical oscillation speed (see chapter 6.1 Technical data).
!
Beware of static electricity risk when the media conductivity is below 1000pS/m. (Recommendations: CLC/TR
50404 or IEC/TS60079-32).
Never touch the moving parts while the Agitator is connected to the power supply.
Maintenance:
Always read the technical data thoroughly (see chapter 6.1 Technical data
