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.
• Socket must be earthed (protective ground contact).
• Caution - Magnetism! Effects of the magnetic field have to be
taken into account (e.g. data storage media, cardiac pacemakers ...).
• Risk of burns! Exercise caution when touching the housing parts and
the heating plate. The heating plate can reach temperatures in excess
of 310 °C. Pay attention to the residual heat after switching off.
• Ensure that the mains power supply cable does not touch the
heating base plate.
• Wear your personal protective equipment in accordance with the
hazard category of the media to be processed. Otherwise there
is a risk from:
- splashing and evaporation of liquids
- ejection of parts
- release of toxic or combustable gases.
• 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.
• Check the appliance and accessories beforehand for damage
each time you use them. Do not use damaged components.
• Gradually increase the speed.
• Reduce the speed if
- the medium splashes out of the vessel because the speed is too high
- the appliance is not running smoothly
- the container moves on the base plate.
• Caution! Only process and heat up any media that has a flash
point higher than the adjusted safe temperature limit that has
been set (50 to 360 °C).
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 Chemglass if you have any
questions.
• Do not operate the appliance in explosive atmospheres, with
hazardous substances or under water.

• 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 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.
(Source: Römpps Chemie-Lexikon and ”Ulmann”, Volume 19)
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),
see fig. 4.

Setting the safe temperature limit
The temperature set for the heating plate (maximum 310 °C) will
be at least 10 °C lower than the safe temperature limit.
Warning: The safe temperature limit must always be set at
least 25 °C lower than the flash point of the media to be processed.
Functional check of inactivating the safety circuit
When using an external PT1000 temperature sensor, the user can
choose between two types of control:
PI mode
Good control results, minimised overshooting, slow rise in temperature.
2P mod (two-point controller)
Maximum heating rate, increased overshooting
Factory setting: PI mode
Operating the device in mode A or B
Mode A
All settings will be stored if the device is switched off or disconnected from the power supply. The agitation and heating functions
will be set to OFF when the device is powered on.
Mode B
All settings will be stored if the device is switched off or disconnected from the power supply. The agitation and heating functions
will be set to ON or OFF when the device is powered on, depending on the previous status of the device.
Factory setting: mode A
The mode selected will be shown on the display when the device is started up.

Changing the temperature control mode
1. Set target temperature to 2 °C
2. Switch off device
3. Hold down Heat/temp knob
4. Switch on device
This activates or deactivates the two-point controller (2P) for the
external PT 1000 temperature sensor (2P appears on the display).
When switching on the device, 2P is also displayed next to the
operating mode A/B when the two-point controller is activated.
When the heating function is active in 2P mode, (with external PT
1000 temperature sensor) the actual temperature flashes - that
notifies the user that the process temperature has been greatly
overshot!
Assembling the stand
