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.

Description
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:
- Excess 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.
It is important to follow these safety instructions to prevent personal
injury and property damage. These instructions apply in addition to
the safety instructions at your workstation.
It is essential that you read the user information before
starting the device.

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.

Safety instructions
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.
•Use PPE (safety gloves, safety shoes, safety goggles).
•Transport the unit carefully. The interior of the unit can also be
damaged by impacts or if it is dropped.
•Do not loiter under the unit during transportation and operation.
•The unit is not intended for use in potentially explosive areas.
•Please observe the specifications for the minimum space
requirement when setting up the unit.
•Only operate the unit in rooms that are well-ventilated, dry and free
of frost.
•Switch the unit off immediately if there is refrigerant leakage.
•Place the unit on a flat surface of non-flammable material.
•Operate the unit under an exhaust hood as much as possible.
•Do not start the unit if it is damaged or leaking.
•Compare the mains voltage and frequency with the specifications on
the type plate.
•Only connect the unit to a fused mains connection via a FI circuit
breaker (Ia=30 mA).
•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.
•Check the mains cable regularly for signs of damage.
•Do not start the unit if it has a damaged power cable.
•Keep the mains cable away from hot pump connections.
•Refer to the safety sticker. Parts of the unit can be hot or cold.
•Never use the unit without bath fluid.
•Do not reach into the thermal 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.
•Adjust over-temperature safety device 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
