Safety instructions
• The distance between the dispersion tool and the vessel bot-
tom should not be less than 30 mm.
• Ensure that the stand does not start to move.
• In the event of unbalance or unusual noises, switch off the
appliance 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.
• If the interaction between the medium and dispersing element
makes a loud noise, be sure to wear your personal protective
equipment.
• Do not touch rotating parts during operation!
• In operation and for a relatively long time afterwards the dis-
persing element and bearing can be very hot. Wear your perso-
nal protective equipment.
• Never cover the ventilation slots or cooling fins on the motor as
these are needed for cooling the drive system.
• Meter powder not too close to the motor. Powder can be
blown away by air turbulences of the drive.
• Abrasion of the dispersion equipment or the rotating accesso-
ries can get into the medium you are working on.
• 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 substances or under water.
• Do not process any flammable or combustible materials.
• Only process media that will not react danger- ously to the
extra energy produced throughprocessing. This also applies to
any extra energy produced in other ways, e.g. through light
irradiation.
• Safe operation is only guaranteed with the accessories descri-
bed in the ”Accessories” chapter.
• Always disconnect the plug before fitting accessories.
• After an interruption in the power supply, or a mechanical in-
terruption during a dispersing process, the unit does not auto-
matically re-start.
Safety instructions T 65 basic ULTRA-TURRAX ®
• Before commissioning, the correct direction of rotation of the
motor must always be ensured (test run without dispersion
tool: motor rotation as indicated on the arrow plate, or clock-
wise rotation, looking down on motor). The wrong direction
of rotation can lead to the rotor or stator coming off the shaft.
• If the unit is operated in different locations with a 5-pin plug,
the direction of rotation must be checked before commissio-
ning, with no dispersion tool fitted.
• An EMERGENCY STOP switch must be installed on this unit.
• 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.
For your protection
• Read the operating instructions in full before
starting up and follow the safety instructions.
• Keep the operating instructions in a place where they can be
accessed by everyone.
• Ensure that only trained staff work with the appliance.
• Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
• Wear your personal protective equipment in accordance with
the hazard category of the medium to be processed. Otherwise
there is a risk of:
- spraying and vapourisation of liquids
- body parts, hair, clothing and jewellery getting caught.
• The device must be wired by a qualified technician before first
use in order to prevent risk of electric shock!
• Use a safety cutout for height adjustable stands!
• If the unit cannot safely switched off during operation, an ad-
ditional easily accessible EMERGENCY STOP switch must be in-
stalled in the working area.
• Set up the stand in a spacious area on an even, stable, clean,
non-slip, dry and fireproof surface.
• Check the appliance and accessories beforehand for damage
each time you use them. Do not use damaged components.
• The appliance is not suitable for manual operation.
• The agitated vessels used for stirring have to be secured. Con-
sider on a good stability of the entire structure.
• Secure the stirring vessel against twisting.
• Glass vessels must always be secured with a clamp to prevent
them spinning. When working in glass vessels, the dispersion
tool must not come into contact with the glass.
• Note the operating instructions of the dispersing tool and ac-
cessories.
• Only dispersing elements approved by IKA ® may be used.
• Do not use the appliance without a dispersing element.
• Use the dispersing tool always inside the stirring vessel.
• Never run dispersion tools dry, as the gasket and bearings will
be destroyed if the tools are not cooled by the medium.
• There may be electrostatic discharges between the medium and
the dispersing instrument shaft which could pose a direct dan-
ger. In some circumstances, the region between medium and
drive shaft, or between rotor and stator, can become electro-
statically charged, and ignite an explosive atmosphere caused
by evaporation of the medium. In addition, with advanced eva-
poration of the medium, the slide ring seal can overheat to such
an extent that it would lead to an ignition or combustion of the
medium. For this reason, no inflammable or combustible mate-
rials must be processed with the dispersion unit.
• Rapid temperature change (thermal shock!) can destroy the
hard metal sealing surfaces of the dispersing tool S 65-KG HH.
• Check that the turning handles are secure and tighten if ne-
cessary.
• Ensure that the shaft of the dispersing instrument is immersed
in the medium to the appropriate depth for that instrument
(see manual of the dispersing tool, chapter "Technical Data")
in order to prevent splashing.
