from the power supply�
NOTICE
safe operation, for example to keep foreign objects and
liquids, etc� from getting into the device�
• The device must only be used as prescribed and as described in the operating instructions� This includes operation by instructed specialist personnel�
• When using critical or hazardous materials in your processes, IKA® recommends to use additional appropriate
measures to ensure safety in the experiment� For example,
users can implement measures that inhibit fire or explosions or comprehensive monitoring equipment�
• Process pathogenic material only in closed vessels under a
suitable fume hood� Please contact IKA® application support if you have any question�
Coverings or parts that can be removed from the device must be put
back on the device again to ensure

• A laboratory circulator heats/refrigerates and circulates
fluid according to specified parameters� This involves hazards due to high and low temperatures, fire and general
hazards due to 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 may become necessary for user to take other
precautionary safety measures�
• Insucient ventilation may result in the formation of explosive mixtures� Only use the device in well ventilated
areas�
WARNING
not be exceeded even in the event of a fault� Check the
safe temperature circuit on a regular basis (see section
"Setting the safety temperature")�
• When device is used for external circulation, extra precaution must be taken for hot/cold liquid 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)�
• Power cable should not get in contact with hot parts and
fluids�
WARNING
• Be careful when filling a hot bath�
CAUTION
• After a power failure during operation, the device may
start automatically (depending on operating mode)�
• Transport the device with care (see section “Moving the
device“)�
If the power switch is not within
reach when device is operating, an
EMERGENCY STOP switch that

Do not start up the device if:
- It is damaged or leaking
- Cable (not only power cable) is
damaged�
At high operating temperature, the
temperature of housing parts, surfaces and tubes can exceed 70 ° C�

• Do not transport or empty the bath while it is still hot/
cold� This may result in accidents, especially scalding injuries or frostbite�
Disposal of the device:
• The device must be disposed of in accordance with national or local regulations�
Fluids:
• Continuous monitoring of the bath and the filling level of
the bath fluid is required, especially at high temperatures�
• To ensure a sucient fluid circulation, the viscosity of the
bath fluid must not exceed of 50mm2/s at the lowest operating temperature�
NOTICE
If water is used at higher temperature, there is heavy loss of fluid due
to the evaporation of the steam�

WARNING
the chemical hazards that may be associated with the bath
fluid used� Observe all safety warnings for the fluids�
• Depending on the bath fluid used and the type of operation, toxic or flammable vapors can arise� Ensure suitable
extraction�
• Do not use any fluid which may cause dangerous reactions during processing�
• Only use recommended bath fluids� Only use non-acid
and non corroding fluids�
