Safety instructions
• Read the operation instructions completely before star-
ting up and follow the safety instructions.
• Keep the operation instructions in a place where they can be
accessed by everyone.
General information
• Ensure that only trained staff work with the appliance.
• Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
• Socket must be earthed (protective ground contact).
Attention - Magnetism!
ATTENTION
Effects of the magnetic field have to be taken
into account (e.g. data storage media, cardiac
pacemakers ...)
Risk of burns!
DANGER
Exercise caution when touching parts of
the housing and the heating plate.
The heating plate can reach dangerous temperatures. Pay atten-
tion to the residual heat on the heating plate after switching off
the stirrer.
The device may only be transported when the heating plate has
cooled down.
Device design:
Do not use the device in explosive atmos-
DANGER
pheres, it is not EX-protected.
With substances capable of forming an
explosive mixture, appropriate safety measures must be applied,
e.g. working under a fume hood.
To avoid body injury and property damage, observe the relevant
safety and accident prevention measures when processing ha-
zardous materials.
• Set up the appliance in a spacious area on an even, stable, clean,
non-slip, dry and fireproof surface.
• The feet of the appliance must be clean and undamaged.
• Ensure that the mains power supply cable does not touch the
heating plate.
• Check the appliance and accessories for damage before each
use. Do not use damaged components.
Permissible medium / contaminants / side reactions
The safety temperature must be set in ac-
WARNING
cordance with EN 61010-2-010 Chapter
"Requirements for devices containing or
using flammable liquids".
- The surface temperature of the flammable medium that is ex-
posed to air may not exceed its flash point.
A danger usually arises if a medium is heated in open vessels.
- The surface temperature of the heating device (e.g. the moun-
ting plate) may not exceed the value of (t - 25) °C (= set value
of the safety circuit) on the surface of the flammable medium
and in contact with air, whereby t is the fire point of the liquid.
A danger usually arises if a medium is heated in glass vessels
(glass breakage).
If a setting made by the user (medium temperature or safety
temperature) could bring a flammable medium into a state in
which the conditions mentioned above could be exceeded, ad-
ditional measures must be introduced that will protect the user
from this danger.
Beware of hazards due to:
WARNING
- flammable materials
- combustible media with a low boiling temperature
- glass breakage
- incorrect container size
- overfilling of media
- unsafe condition of container.
• Process pathogenic materials only in closed vessels under a suitable
fume hood.
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.

• The heating plate can heat up due to the action of the drive
magnets at high motor speeds, even if the heater is not opera-
tional.
• Please consider any possible contaminations and unwanted
chemical reactions.
• 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.

WARNING
ment in accordance with the hazard
category of the media to be processed.
There may be a risk from:
- splashing and evaporation of liquids,
- ejection of parts,
- release of toxic or combustable gases.
• Reduce the speed if:
- the medium splashes out of the vessel,
- the appliance is not running smoothly,
- the container moves on the heating plate.
Accessories
• Safe operation is guaranteed only with the use of original IKA
accessories.
• Always disconnect the plug before attaching accessories.
• Observe the operating instructions of the accessories.
• Ensure that the external temperature sensor is inserted into
the medium to a depth of at least 20 mm when connected.
• Accessories must be securely attached to the device and can-
not come off by themselves. The centre of gravity of the as-
sembly must lie within the surface on which it is set up.
Power supply / Switching off
•The voltage stated on the type plate must correspond to the
mains voltage.
•The socket for the mains cord must be easily accessible.
•The appliance can only be disconnected from the mains sup-
ply by pulling out the mains plug or the connector plug.
The device will automatically restart in

mode B following any interruption to
the power supply. (RH digital)
For protection of the equipment
• The appliance may only be opened by experts.
• Do not cover the device, even partially e.g. with metallic plates
or film. This may result in overheating.
• Protect the appliance and accessories from bumps and impacts.
• Keep base plate clean.
• Observe minimum distances between devices. Between de-
vice and wall should be 100 mm (min), above the assembly
should be 800 mm (min).
