The safe temperature limit must always be set to at least 25 °C
lower than the fire point of the media used.
• Beware of hazards due to:
- flammable materials
- combustible media with a low boiling temperature
- glass breakage
- incorrect container size
- overfilling of media
- unsafe condition of container.
• The appliance may heat up when in use.
• The base plate can heat up due to the action of the drive magnets
at high motor speeds, even if the heater is not operational.
• Process pathogenic materials only in closed vessels under a suit-
able extractor hood. Please contact IKA if you have any questions.
• Do not operate the appliance in explosive atmospheres, with
hazardous substances or under water.
• Only process media that will not react dangerously to the extra
energy produced through processing. This also applies to any
extra energy produced in other ways, e.g. through light irradiation.
• Please observe the operating instructions for any accessories used.
• Ensure that the external temperature sensor (PT 1000, ETS-D ...)
is inserted in the media to a depth of at least 20 mm.
• The PT 1000 external temperature sensor must always be inser-
ted in the media when connected.
• Safe operation is only guaranteed with the accessories described
in the ”Accessories” chapter.
• Accessories must be securely attached to the device and cannot
come off by themselves. The centre of gravity of the assembly
must lie within the surface on which it is set up.
• Always disconnect the plug before fitting accessories.
• The appliance can only be disconnected from the mains supply
by pulling out the mains plug or the connector plug.
• The socket for the mains cord must be easily accessible.
• The device will automatically restart in mode B following any
interruption to the power supply.
• It may be possible for wear debris from rotating accessory parts
to reach the material being processed.
• When using PTFE-coated magnetic bars, the following hase to
be noted: Chemical reactions of PTFE occur in contact with mol-
ten or solute alkali metals and alkaline earth metals, as well as
with fine powders of metals in groups 2 and 3 of the periodic
system at temperatures above 300 °C - 400 °C. Only elementa-
ry fluorine, chlorotrifluoride and alkali metals attack it; halogena-
ted hydrocarbons have a reversible swelling effect.

For protection of the equipment
• The appliance may only be opened by experts.
• The voltage stated on the type plate must correspond to the mains
voltage.
• Do not cover the device, even partially e.g. with metallic plates
or film. This results in overheating.
• Ensure that the base plate is kept clean.
• Protect the appliance and accessories from bumps and impacts.
• Observe the minimum distances between the devices, between
the device and the wall and above the assembly (min. 800 mm),
see fig. 3.
