Safety instructions

General information

Read the operating instructions in its entirety before using the device and follow the safety instructions.
Keep the operating instructions in a place where it can be accessed 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!
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 parts of the housing and the heating plate.
The heating plate can reach dangerous temperatures. Pay attention 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 atmospheres, 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 hazardous materials.
Set up the device 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.
Ensure that the power cord set / temperature sensor cable does not touch the heating plate.
Check the device and accessories for damage before each use. Do not use damaged components.
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.

Permissible medium / contaminants / side reactions

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.
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.
Process pathogenic materials only in closed vessels under a suitable fume hood.
In unsupervised and safe operation, this device may only handle or heat media whose flash point is above the set safety temperature limit. (Flashpoint min.: 575 °C, acc.to EN 61010-2-010)
The heating plate can heat up due to the action of the magnets at high motor speeds, even if the heater is switched off.
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. (Source: Römpps Chemie-Lexikon and ”Ulmann”, Volume 19)

Procedures during sample runs

Wear your personal protective equipment in accordance with the hazard category of the media to be processed. There may be a risk from:
- plashing and evaporation of liquids,
- ejection of parts,
- release of toxic or combustible gases.
Position the knob at the left stop before starting up. Gradually increase the speed.
Reduce speed if:
- medium splashes out of vessel because the speed is too high,
- device is not running smoothly,
- container moves on the base plate,
- an error message is displayed.

Accessories

Safe operation is guaranteed only with the use of original IKA accessories.
Always disconnect the plug before attaching 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.
Observe the operating instructions of the accessories.

Power supply / Switching off the device

The device will automatically restart following any interruption to the power supply.
The voltage stated on the type plate must correspond to the mains voltage.
The outlet for the mains plug must be easily accessible.
The device can only be disconnected from the mains outlet by pulling out the power cord set or the connector plug.

For protection of the equipment

The device may only be opened by qualified and IKA approved experts.
Do not cover the device, even partially e.g. with metallic plates or film. This may result in overheating.
Protect the device and accessories from bumps and impacts.
Keep the base plate clean.
Observe the minimum distances:
- between devices min. 100 mm,
- between device and wall min. 100 mm,
- above the device min. 800 mm.

Observe the minimum distances illustration
