2Intended use
JULABO circulators are laboratory devices which are designed for the
temperature control of certain liquid media in a bath tank or with a
refrigeration unit. The bath fluids recommended by JULABO must be
used as tempering media.
Units with pump connections allow the tempering tasks to be carried out
in an external temperature control system.
JULABO circulators are not designed for the direct temperature control of
foods, semi-luxury foods and tobacco, or pharmaceutical and medical
products.
•Direct temperature control means unprotected contact between the
object and the tempering medium (bath fluid).
•The devices are not suitable for use in potentially explosive
environments.

3Description
•These circulators are operated via the splash-proof keypad. The
microprocessor technology allows the setpoint to be set, displayed
and saved using the temperature display LED.
•The PID temperature control automatically adjusts the heat supply to
the requirements in the bath.
•ATC - Absolute Temperature Calibration (1-point calibration)
•The pump function can be switched from internal to external
circulation by a simple switchover button.
•Safety equipment to IEC 61010-2-010:
- The excessive temperature protector is a safety device which
is independent of the control circuit whose value is set using
a tool (screwdriver).
- A float switch acts as the low level safety device. If these
safety devices trip, the heater and circulating pump are
completely shut down.
•Interfaces:
- CAN bus to communicate with the refrigeration machine
- USB connector to act as host to update and read data. USB device
for remote control.

4Explanation of safety information
The operating manual contains warnings to increase safety when using
the unit. The general warning sign, consisting of an equilateral triangle
surrounding an exclamation sign and reproduced in various signal
colors, is preceded by the signal words.
"Warning of a dangerous situation".
The significance of the danger is classified with a signal word. Read the
instructions carefully and follow them.
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
Designates states which only occur after the start of an action and
could have been prevented if the warning had been heeded.

5Safety instructions
It is important to follow these safety instructions to prevent personal
injury and property damage. These instructions apply in addition to
standard safety practices for working places.
•It is essential that you read the user information before starting the
unit.
•Place the unit on a flat surface and a mat made of non-flammable
material.
•Do not start the unit if it is damaged or leaking.
•Only connect the unit to a power socket with ground contact (PE –
protective earth)!
•The power supply plug serves as safe disconnecting device from the
power supply network and must be freely accessible at all times.
•Do not start the unit if it has a damaged power cable.
•Refer to the safety sticker.
•Never use the unit without bath fluid.
•Check the filling level of the bath fluid at regular intervals. The pump
and heater must always be completely covered with bath fluid.
•Set the excess temperature protector to at least 25 °C below the
flash point of the bath fluid.
•Consider the restricted working temperature range if you are using
plastic bath tanks.
•Monitor the heat expansion of the bath oils as the bath temperature
rises.
•Prevent water getting into hot bath oils.
•Use suitable tubing.
•Secure the tubing connections to prevent them sliding off.
•Do not bend the bath fluid tubing.
•Check the hoses at regular intervals for signs of material fatigue (for
example cracking).
•Do not drain the bath fluid when it is hot.
•Check the temperature of the bath fluid before draining it, for
example by switching on the unit briefly.
•Switch off the unit and pull the plug before moving the unit or
carrying out service or repair work.
•Have all service and repair work carried out by authorized specialists
only.
•Switch off the unit and disconnect it from the power supply before
cleaning it.

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 operative must receive regular training about the dangers involved
with their work and about action to prevent such dangers.
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 operative
keypad (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 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 susceptible 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.
