•The rating of power supply must match with the specified rating.
•Process pathogenic materials only in a closed vessel under a suitable extractor hood.
Do not operate the appliance in explosive atmospheres, with the hazardous substance
or under water.
•Only that liquid should be used for mixing which does not react dangerously to the extra
energy produced through processing. This also applies to any extra energy produced
in other ways. For example: Through light irradiation, through surrounding temperature
etc.
•Abrasion of the dispersion equipment or the rotating accessories can get into the
medium you are working on.
•The chemical reaction of PTFE can occur when in contact with molten or dissolved
alkaline earth metals. Only elementary fluorine, chlorine trifluorine and alkaline metals
do attack PTFE, halogen hydrocarbons have a reversible swelling effect
•To protect do not cover the device, even partially, with elements such as metallic plates
or sheets otherwise it may overheat. Ensure that mounting plate remains clean.
•Non-observance of the safety notes can cause damage to the device and injuries to
