Operational noise
Use suitable hearing protection when working continuously within a radius
of 2 m. Hearing impairment may occur when operating without hearing
protection - the ultrasonic cavitation noise typical of the process can be
very unpleasant.
Only operate the vacuum function with the lid closed.
Check the overall condition of the unit according to the maintenance
schedule. Only switch on the unit if the check of the overall condition of the
unit shows no deficiencies. Inform your supervisor if the check of the
overall condition of the unit shows any deficiencies.
Dangers due to ultrasonic cavitation
Ultrasound has a cell-destroying effect. Do not immerse any parts of the
body (e.g. hand, foot) or living beings (animals and plants) in the bath; in
particular, do not reach into the sonication fluid during ultrasound
operation.
