Safety instructions
• Please read the instruction manual in full before use and
follow the safety instructions.
• Keep the instruction manual in a place where it can be accessed
easily.
General instructions
• Ensure that only trained staff use the device.
• Be sure to comply with all safety instructions, directives and all
matters of health, safety and accident prevention in the workplace.
• The plug must be earthed (grounded contact).
Caution - magnetism!
Beware of possible effects from the
magnetic field (pacemakers, data media,
etc.).
Burns hazard!
Exercise caution when touching housing
components and the heating plate. The
heating plate can reach temperatures of up to 320°C. Watch for
residual heat after appliance has been switched off.
The device should only be transported once it has cooled!
Device configuration
Do not operate the device in explosive
atmospheres, in the presence of hazard-
ous materials or under water.
• Install the device on a flat, stable, clean, non-slip, dry and fire-
resistant surface.
• The device feet must be clean and undamaged.
• The power supply cable and cables to the external sensors must
not be allowed to come into contact with the heated mounting
plate.
• Prior to each use, always check the device and accessories for
damage. Never use damaged parts.
Permissible media / Contamination / Side reactions
Caution! Only media whose flashpoint
lies above the set safety temperature
limit (50°C - 380°C) may be processed
or heated with this device.
The set safety temperature limit must be at least 25°C below the
flashpoint of the medium in use.
Pay attention to the risks associated
with:
- flammable materials
- flammable media with low steam pressure
- glass breakage
- incorrect vessel size
- overfilling of medium
- unstable vessel.
• Only process pathogenic materials in closed vessels under a suit-
able extractor hood. Please contact IKA ® if you have any ques-
tions.
Only work with media for which the en-
ergy input during processing is harmless.
This also needs to take into account
other sources of energy such as, for example, light irradiation.
• At high speeds the mounting plate is liable to warming, even if
the device is not in heating mode.
• Bear in mind the possibility of contamination or unwanted chem-
ical reactions.
• There is the possibility that friction from rotating accessory parts
can result in contamination of the medium being processed.
• Bear in mind the following when using PTFE-coated magnetic
rods: 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 table
ATTENTION
DANGER
at temperatures above 300-400°C. Only elementary fluorine,
chlorine trifluoride and alkali metals attack it; halogenated hy-
drocarbons have a reversible swelling effect.
(Source: Römpp “Chemie-Lexikon” and “Ullmann” Vol. 19)
• Only glass-coated magnetic rods should be used in conjunction
with solute alkali metals or alkaline earth metals or at tempera-
tures above 250°C.
Performing trials
Always wear personal protective
equipment in accordance with the hazard
class of the media being worked with.
Otherwise there is the risk of the following:
- spraying and evaporation of liquids
- ejection of parts
- release of toxic or inflammable gases.
• If any of the following happens, reduce the speed:
- medium sprays out of vessel due to excessive speed
- process is not smooth
- vessel moves around on the mounting plate.
Accessories
• Safe operation can only be ensured when working with acces-
sories as described in the “Accessories” section.
• Only put together accessories with the power supply cable dis-
connected.
• Refer to the operating instructions for the accessories.
• Immerse the external temperature sensor (PT1000, ETS-D, etc.)
at least 20 mm into the medium.
• The PT1000 external temperature sensor must always be inside
the medium.
• Accessories must be connected securely to the device and must
not come loose on their own. The centre of gravity of the device
must be located within the mounting plate.
Power supply / switching off the device
• The specified settings on the rating plate must coincide with the
actual power supply.
• The plug for the power supply connection must be easy to access
and remove.
• The device is only disconnected from the power supply when the
power or device plug is removed.
After an interruption to the power sup-
ply, the device starts up again in Mode B.
Protection of the device
• The device must only be opened by trained, skilled personnel.
• Do not cover the device, even partially, with elements such as
metallic plates or sheets otherwise it may overheat.
• Avoid knocks or impact to the device or accessories.
• Ensure the mounting plate remains clean.
• Observe minimum distances between devices, between the device
and the wall, and above and below the device (min. 800 mm).
