This signal word designates a danger with a high level of risk which, if
it not prevented, will result in death or serious injury.
This signal word designates a danger with a medium level of risk
which, if it not prevented, may result in death or serious injury.
This signal word designates a danger with a low level of risk which, if it
not prevented, may result in minor or moderate injury.
Designates a possibly harmful situation. If it is not prevented, the
system or something near it may be damaged.
4.1 Explanation of other information
TIP
Your attention is drawn to something special by this.
Designates user tips and other useful information.
Dangers at second glance

Operator's responsibility - safety instructions
6Operator's responsibility - safety instructions
Products manufactured by JULABO GmbH ensure safe operation when
installed, operated and according to common safety regulations. This
section explains the potential dangers which may occur when operating
the unit and specifies the most important safety measures to prevent
these dangers as far as possible.
6.1 Requirements for the operating personnel
The operator is responsible for the qualifications of the personnel
operating the unit. Ensure that the personnel who operate the unit are
trained in the relevant work application by a trained person.
The operator must receive regular training about the dangers involved
with their work as well as preventive action.
Ensure that everybody involved with the operation, maintenance and
installation have read and understood the safety information and the
operating manual. The unit may only be configured, installed,
maintained and repaired by trained personnel.
If hazardous substances or substances which may become hazardous are
used, the unit may only be used by a person who is completely familiar
with these substances and the unit. This person must be able to assess
the possible dangers in full.
6.2 Operating and ambient conditions for using the unit
•Avoid impacts on the housing, vibrations, damage to the touch-
sensitive foil (keys and display) and heavy soiling.
•Ensure that the product is checked at regular intervals suitable for its
frequency of use to ensure that it is in perfect condition.
•Check the proper condition of the mandatory warning, prohibition,
and safety labels at regular intervals, but at least every 2 years.
•Ensure that the mains supply has a low impedance to prevent
influencing of other units powered in the same mains.
•The unit is designed for operation in a controlled electromagnetic
environment. This means that in an environment of this nature,
transmission equipment such as mobile phones should not be used
in the immediate vicinity.
•Other units with components which are suceptible to magnetic fields
may be influenced by magnetic radiation. We recommend to
maintain a minimum distance of 1 m.
•Permissible ambient temperature max. 40 °C, min. 5 °C.
•The relative humidity should not exceed 50 % (40 °C).
•Do not store in an aggressive atmosphere. Protect from dirt.
•Protect from direct sunlight.

correct operation. Caustic or corrosive bath fluids must not be used.
The formation of explosive mixtures is possible if the ventilation is
inadequate.
Only use the units in well ventilated areas. The unit is not suitable for
use in potentially explosive environments.
When using hazardous substances or substances which may be
hazardous, the operator must apply the enclosed safety symbols (1; 2; 3)
on the control side panel where they are clearly visible:
1
Warning of a danger zone. Attention!
Observe documentation (Operating manual, safety data sheet).
