IKA ULTRA-TURRAX T 18 basic Mode D'emploi page 14

• Reduce the speed if the medium splashes out of the vessel be-
cause the speed is too high.
• Before switching on the dispersing instrument make sure that its
shaft is immersed min. 45 mm in the medium to prevent the
medium from splashing out.
• The distance between the dispersion tool and the vessel bottom
should not be less than 10 mm (fig. 1).
• In the event of unbalance or unusual noises, switch off the appli-
ance immediately. Replace the dispersing element. If there is no
difference after the change of the dispersing tool, return it to the
dealer or the manufacturer along with a description of the fault.
• Do not touch rotating parts during operation.
• Please note that the dispersing element and the journal bearings
can become extremely hot during use.
• 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.
• Do not process any flammable or combustible materials.
• Process pathogenic materials only in closed vessels under a suitable
extractor hood. Please contact IKA if you have any questions.
• Abrasion of the dispersion equipment or the rotating accessories
can get into the medium you are working on.
• Meter powder not too close to the flange. Powder can be blown
away by air turbulences of the drive.
• The appliance starts up again following a cut in the power supply.
Please note that the appliance must be switched off at the on/off
switch in this case before the power supply is reconnected.
• 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.
• Always disconnect the plug before fitting accessories.
• Safe operation is only guaranteed with the accessories described
in the "Accessories" chapter.
• Never run dispersion tools dry, as the gasket and bearings will be
destroyed if the tools are not cooled by the medium.
• The gasket and bearings are made of PTFE and rustproof steel;

the following points should therefore be noted: Chemical reac-
tions 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 reversi-
ble swelling effect.

For protection of the equipment
• The voltage stated on the nameplate must correspond to the
mains voltage.
• Socket must be earthed (protective ground contact).
• Protect the appliance and accessories from bumps and impacts.
• The appliance may only be opened by experts.
• Do not cover the ventilation slots on the drive in order to ensure
adequate cooling of the drive.
