Safety instructions
Safety instructions - performance of trials
•Wear your personal protective equip-
ment 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.
• Immerse external temperature sensors (PT 1000 ...) at least 20
mm deep into the medium or insert the sensor into the hole
provided for the purpose in the temperature control block.
• The PT 1000 external temperature sensor must always be inser-
ted in the block / media when connected.
• Do not heat liquid media except with the block. Never pour
liquid media directly on to the heating plate!
• Safe operation is only guaranteed with the accessories descri-
bed in the ”Accessories” chapter.
• Always disconnect the plug before fitting accessories.
• Accessories must be securely attached to the device and can-
not come off by themselves. The centre of gravity of the as-
sembly must lie within the surface on which it is set up.
• Refer to the operating instructions for the accessories.
Safety instructions - power supply/ switching off the device
•The appliance can only be disconnected
from the mains supply by pulling out the
mains plug or the connector plug.
• The device will automatically restart in mode B following any
interruption to the power supply.
For protection of the equipment
• The appliance may only be opened by experts.
• 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, bet-
ween the device and the wall and above the assembly (min.
800 mm), see fig. 2.
General safety instructions
• 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).
• Before starting the device for the first time, ensure that the
connector cable is suitable for the type of socket used and that
a safe protective earth connection is assured.
• Risk of burns! Exercise caution when
touching the housing parts and the hea-
ting plate. The heating plate can reach
temperatures in excess of 120 °C. Pay at-
tention to the residual heat after switching
off. The device may not be transpor-
ted unless it is cold!
Safety instructions - device arrangement
• Do not operate the appliance in explo-
sive atmospheres, with hazardous subs-
tances or under water.
• 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.
• The voltage stated on the type plate must correspond to the
mains voltage.
• The socket for the mains cord must be easily accessible.
• The power supply cable and cables to the external sensors must
not be allowed to come into contact with the hot mounting plate.
• Check the appliance and accessories beforehand for damage
each time you use them. Do not use damaged components.
Safety instructions - permissible media
• Caution! Only media whose flashpoint
lies above the safety temperature limit of
130 °C may be processed or heated with
this device.
• Beware of hazards due to:
- flammable materials
- combustible media with a low boiling
temperature
- glass breakage
- incorrect container size
- overfilling of media (in a beaker)
- unsafe condition of container.
• Process pathogenic materials only in closed vessels under a
suitable extractor hood. Please contact IKA ® if you have any
questions.
• Only process media that will not react
dangerously to the extra energy produ-
ced through processing. This also applies
to any extra energy produced in other
ways, e.g. through light irradiation.
• Bear in mind the possibility of contamination that might lead to
undesirable chemical reactions.
