IKA RET basic safety control Mode D'emploi page 14

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 suitable extractor
hood. Please contact IKA if you have any questions.
®
• Do not operate the appliance in explosive atmospheres, with hazardous subs-
tances or under water.
• Only process media that will not react dangerously to the extra energy pro-
duced 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 inserted 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 has to be noted:
Chemical reactions of PTFE occur in contact with molten 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
elementary fluorine, chlorotrifluoride and alkali metals attack it; halogenated
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).
