Safety instructions

To 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).
  • Attention – Magnetism! Effects of the magnetic field have to be taken into account (e.g. data cardiatic, carriers pacemakers…).
  • Risk of burns! The heating plate can reach temperatures in excess of 500 °C. Pay attention the residual heat after switching off..
    Please make sure that the mains cable does not contact the heating plate
  • Wear your personal protective equipment in accordance with the hazard category of the medium to be processed. Otherwise there is a risk of:
    • splashing liquids
    • projectile parts
    • release any 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.
  • Position the knob at the left stop before starting up. 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 set-up surface.


Only process and heat up any media that has a flash point higher than the adjusted target temperature (0 to 550 °C) that has been set.
The target temperature must always be set to at least 25 °C lower than the fire point of the media used.

  • When using PTFE-coated magnetic bars, the following hase to be noted: Chemical reactions of PTFE occur in contact with molten or dissolved alkaline and alkaline – earth metals, as well as with fine-particled powders of metals of the 2. and 3. group of the periodical system at temperatures above 300-400°C.
  • Only elementary fluorine, chlorine trifluoride und alkaline metals do attack PTFE, halogen hydrocarbons have a reversibly swelling effect.
  • Check the appliance and accessories beforehand for damage each time you use them. Do not use damaged components.
  • Only replace damaged parts with spare parts identical to the original in function and quality.
  • Do not use the device if the ceramic set-up surface is damaged e.g. scratches, splinters or corrosion. A damaged set-up surface could break if used.
  • Beware of the risk of
    • flammable materials
    • glass breakage as a result of mechanical shaking power
    • incorrect container size
    • too much medium
    • unsafe condition of container
  • 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 operate the appliance in explosive atmospheres, with hazardous substances or under water.
  • A seperation from the line is made with the equipment only by pulling net and/or device plug.
  • Safe operation is only guaranteed with the accessories described in the ”Accessories” chapter.
  • Always disconnect the plug before fitting 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 the set-up surface.
  • The appliance starts up again automatically following a cut in the power supply.
  • The appliance may heat up when in use.
  • Abrasion of the dispersion equipment or the rotating accessories can get into the medium you are working on.

To the protection of the equipment

  • The voltage stated on the nameplate 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.
  • Observe the minimum distances between devices, between the device and the wall as given in the Fig. 2 and above the assembly (min. 800mm)


  • Unpack
  • Please unpack the device carefully
  • In the case of any damage a fact report must be sent immediately (post, rail or forwarder)

Delivery scope

  • Heating magnetic stirrer or Magnetic stirrer or Heating device
  • Mains cable
  • Operating instructions

Correct use

  • For mixing and/or heating liquids
  • Range of use

Error codes

Footstep during the enterprise a disturbance up, is indicated these with the devices to HS and HP by an error message in the display (C).
Whenever an error message appears switch the device off to cool down.

Error code Cause Solution
E1 Inner temperature too high •  switch off the unit and allow it cool down
E6 Motor seized •  Stirring bars inappropriate

•  Reduce the viscosity

•  Foreign bodies in the equipment remove

E9 Safety circuit ETC •  Plug the contact plug (G)

•  Plug the contact thermometer

•  Connecting cable, plug or contact tthermometer defect, exchange

Have the device repaired if the error is not corrected using the measures described or if another error code is displayed.
