in a place where it can be accessed easily.
• Beware of the possible effects of magnetic field on pacemakers, data media,
etc.
• Properly lift the device with both hands while moving or installing.
• Do not place any steel or magnetic material on the top surface except the
recommended magnetic stirring bar with beaker or flask in between. Doing this can
affect the magnetism of device.
• Wear your personal protective equipment in accordance with the hazardous category
of the media to be processed. Otherwise, there is a risk from:
Splashing of liquids.
Ejection of parts.
The release of toxic or combustible gases.
• The top surface must be clean and kept intact. Wear protective gloves while cleaning
the device. Use a soft mild cloth to clean.
• Do not use damaged beaker, flask, stirring bar or any other component for operation.
It may affect the efficiency of the device.

• Give specific attention to the risks associated with:
Flammable materials
Flammable media with low steam pressure
Overfilling of medium
Incorrect vessel size
Unstable vessel
Glass breakage
• Note that, there is a possibility of contamination or unwanted chemical reaction.
• 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
the user.
