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.
Caution!
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)
