result in death, serious injury.
Danger!
Indicates a hazardous situation, which, if not avoided,
can result in
death, serious injury.
Warning!
Indicates a potentially hazardous situation, which, if not avoided, can
result in injury.
Caution!
!
Indicates practices which, if not avoided, can result in equipment damage.
Notice!
/// General Symbols
Position number
A–––
Correct / Result
Shows the correct execution or the result of an action step.
Wrong
Shows the incorrect execution of an action step.
Note
Displays action steps that require particular attention to detail.
/// Device setup
Caution!
› The power switch of the device must be accessed immediately, directly and without risk at
any time. If access to the power switch cannot be ensured, an additional emergency stop
switch that can be easily accessed must be installed in the work area.
!Notice!
›
Set up the device in a spacious area on an even, stable, clean, non-slip, dry and fireproof surface.
› The device has been constructed to the requirements of EU (European Union) and EFTA
(European Free Trade Association) countries.
›
Insucient ventilation may result in the formation of explosive mixtures. Only use the device
in well ventilated areas.
Safety instructions
/// General information
›
Read the operating instructions completely before starting up 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.
› The device must only be used in a technically perfect condition.
!Notice!
› Pay attention to the marked sites in Fig. 1.
!
/// Working with the device
Danger!
› 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 preven-
tion measures when processing hazardous materials.
Warning!
›
Process pathogenic material only in closed vessels under a suitable fume hood. Please contact
IKA application support if you have any question.
› When using critical or hazardous materials in your processes, IKA recommends to use ad-
ditional appropriate measures to ensure safety in the experiment. For example, users can
implement comprehensive monitoring equipment.
Caution!
› Do not start up the device if:
- It is damaged or leaking
- Cable (not only the power cable) is damaged.
We declare under our sole responsibility that this product corresponds to the regulations

/// Disposal instructions
›
The device, accessories and packaging must be disposed of in accordance with local and
national regulations.
/// Maintenance
› The device must only be opened by trained specialists, even during repair. The device must
be unplugged from the power supply before opening. Live parts inside the device may still
be live for some time after unplugging from the power supply.
/// Power supply / switching off the device
›
The voltage stated on the type plate must correspond to the power voltage.
› The device can only be disconnected from the power supply by pulling out the power plug
or the connector plug.
› The device must only be operated with the original power cord set.
› The socket for the power cord must be easily accessible.
› Socket must be earthed (protective ground contact).
› After a power failure during operation, the device may start automatically (depending on
operating mode).
› Disconnect the power plug before attaching or changing any accessories.
› Disconnect the power plug before cleaning, maintenance and transportation of the unit.
/// Fluid
Warning!
› Only use the fluids, which fulfill the requirements for safety, health and device compatibility.
Be aware of the chemical hazards that may be associated with the bath fluid used. Observe
all safety warning for the fluids.
›
Depending on the bath fluid used and the type of operation or toxic can arise. Ensure suitable
extraction.
› Do not use any fluid which may cause dangerous reactions during processing.
!Notice!
› Only use recommended bath fluid. Only use non-acid and non corroding fluid.
›
Never operate the device without sucient fluid! Check the fluid level detection at a regular
basis.
› Continuous monitoring of the filling level of the bath fluid is required.
›
To ensure a sucient fluid circulation, the viscosity of the bath fluid must not exceed of 50 mm/s
at the lowest operating temperature.
› Untreated tap water is not recommended. It is recommended to use distilled water or high
purity water (ion exchangers) and add 0.1 g soda (sodium carbonate NaCO) /liter, to reduce
corrosive properties.
› Don’t use following fluids:
- Untreated tap water
- Acids or bases
- Solutions with halides: chlorides, fluorides, bromides, iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water.
/// Accessories
› Protect the device and accessories from bumping and impacting.
› Check the device and accessories beforehand for damage each time when you use them. Do
not use damaged components.
›
Safe operation is only guaranteed with the accessories described in the ”Accessories” section.
!Notice!
› Covers or parts that can be removed from the device without tools must later be refitted to
ensure safe operation. This will prevent the infiltration of foreign objects, liquids and other
contaminants.
› The feet of the device must be clean and undamaged.
› Always empty the bath if the unit is unused for long time.
› A laboratory circulator refrigerates and circulates fluid according to specified parameters. This
involves hazards due to high and low temperatures and general hazards due to the device
of electrical energy. The user safety can not be ensured simply with design requirements on
the part of the device. Further hazard sources may arise due to the type of tempering fluid,
e.g. by exceeding or undercutting certain temperature thresholds or by the breakage of the
container and reaction with the carrier fluid. It is not possible to consider all eventualities.
They remain largely subject to the judgment and responsibility of the operator. For this
reason, it become necessary for user to take other precautionary safety measures.
› The device may only be used as prescribed and as described in these operating instructions.
This includes operation by instructed specialist personnel.
› When device is used for external circulation, extra precaution must be taken for cold fluid
leakage due to damaged hose.
- Use suitable hoses for connection.
- Secure hoses and tubes against slippage and avoid kinks.
- Check hoses, tubes and bath at regular intervals for possible material fatigue (cracks/leaks).
› Do not transport or empty the bath while it is still cold.
› Always empty the bath before moving the unit.

/// Refrigerant
Warning!
› The device is not allowed to be used in an ATEX (Atmosphere Exlosible) zone.
› Flammable refrigerant used. Do not use mechanical devices or other means to accelerate the
defrosting process, other than those recommended by the manufacturer.
› Do not damage the refrigerant circuit.
›
Insufficient ventilation may result in the formation of explosive mixtures. Only use the device
in well ventilated areas and keep all air vents open.
›
Flammable refrigerant used. Only the manufacturer may open and repair the closed refrigeration
system.
› The minimum room size is 9 m³, so that in the event of an error (exit of the complete refrigerant
filling quantity) no flammable refrigerant-air mixture can arise (R 290 max. 8 g/m³ ambient air).
/// Range of use
Indoor environments similar to that a laboratory of research, teaching, trade or industry.
The safety of the user cannot be guaranteed:
›
if the device is operated with accessories that are not supplied or recommended by the
manufacturer.
›
if the device is operated improperly or contrary to the manufacture’s specifications.
›
if the device or the printed circuit board are modified by third parties.

Installation
›
Place the unit on an even, stable, clean, nonslip, dry and fireproof surface.
›
Keep at least 20 cm of open space on the front and rear side.
›
The place for installation should be large enough and provide sucient air ventilation to
ensure the room does not warm up excessively because of the heat from device radiates
to the environment.
›
Do not set up the device in the immediate vicinity of heat sources and do not expose to
sun light.
›
Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via
the venting grids! Never cover these venting grids!
