Safety instructions
For your protection
• Read the operating instructions completely before star-
ting up and follow the safety instructions.
• Keep the operating instructions in a place where it can be ac-
cessed by everyone.
• Ensure that only trained staff work with the device.
• Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
• Electrical outlet must be grounded (protective ground contact).
Attention – Magnetism!
ATTENTION
Effects of the magnetic field have to be ta-
ken into account (e.g. data storage media,
cardiac pacemakers ... ).
RT
DANGER
Risk of burns!
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.
RT
WARNING
Ensure that the power cord set / temperature
sensor cable does not touch the heating plate.
• Wear your personal protective equipment 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 combustible gases.
• Set up the appliance in a spacious area on an even, stable, clean,
non-slip, dry and fireproof surface.
• The feet of the device must be clean and undamaged.
• Check the device and accessories for damage before each use.
Do not use damaged components.
• Gradually increase the speed.
• Reduce the speed if
- medium splashes out of vessel because the speed is too high,
- device is not running smoothly,
- container moves on the base plate.
RT
WARNING
The safety temperature must be set in ac-
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.

• The appliance may heat up when in use.
• The base plate can heat up due to the action of the drive mag-
nets at high motor speeds, even if the heater is not operational.
• Process pathogenic materials only in closed vessels under a sui-
table extractor hood. Please contact IKA if you have any questi-
ons.
Do not use the device in explosive atmos-

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 haz-
ardous materials.
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.
• Safe operation is guaranteed only with the use of original IKA
accessories.
• 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.
• 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 so-
lute 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 alkalimetals attack it; halogenated hydro-
carbons 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.
• Protect the appliance and accessories from bumps and impacts.
• Ensure that the base plate is kept clean.
• Observe the minimum distances between the devices, between
device and wall and minimum distances (min. 800 mm) above
the assembly, see Fig. 2.

Unpacking
• Unpacking
- Please unpack the device carefully
- In the case of any damage a detailed report
must be sent immediately (post, rail or forwarder)
Correct use
• Use
- For mixing and / or heating liquids
• Range of use
Indoor environments similar to that a laboratory of research,
teaching, trade or industry area.
Commissioning
RO/RT
Observe the ambient conditions (temperature, humidity, etc.)
listed under Technical Data.
The device is switched on and off via the switch (A) located on
the right-hand side of the device. On the front panel a small
arrow labelled Power above the display (B) indicates the location
of the switch.
Temperature limit
RT
The max. achievable hotplate temperature is limited to 150 °C
due to the design. Once this limit has been attained, the device
switches off the heating.
Setting the temperature limit
RT
The temperature limit is set as follows:
Switch the device on using the On/Off switch
on the right side of the device.
As soon as the display shows SAFE, press and
hold down the Temp membrane key and use
Stirring function
RO/RT
The stirring function is started and stopped by pressing the „Start/
Stop" button (C).
