3 Intended use
This section defines the purpose of the unit so that the operator can operate the
unit safely and avoid misuse.
JULABO circulators are laboratory devices that are designed for temperature
control applications with liquid media in a bath tank or with a cooling machine.
An external loop circuit can be connected to the pump connectors so that the
temperature of the bath media can be kept constant.
Only use the device if it is in technically perfect condition and only use it in
accordance with its intended use. Be aware of safety issues or hazards and
comply with the operating manual! In particular, always immediately rectify
faults that could impair safety!
The circulators are not suitable for direct temperature control application of
food, other consumables or pharmaceutical or other medical products.
The devices are not suitable for use in an explosive environment.
The devices are not intended for use in living areas. They may cause interference
with radio reception.

4.1 General Safety Instructions for the operating company
This section outlines the General Safety Instructions that must be observed by
the operator to ensure safe operation.
• The operator is responsible for the qualifications of its operating personnel.
• The operator must ensure that the operating personnel has been instructed
in use of the device.
• The device operators must receive regular training about the dangers
involved in their work and measures to prevent such dangers.
• The operator must ensure that persons entrusted with the operation,
installation and maintenance have read and understood the operating
manual.
• The device may only be configured, installed, maintained and repaired by
trained personnel with appropriate qualifications.
• If hazardous substances or substances that may become hazardous are
used, the device may only be used by personnel who are qualified to handle
these substances and the device.
• The operator must ensure that the device is checked for safety and
functionality at regular and usage-related intervals.
• The operator must ensure that the mains supply has a low impedance to
prevent influencing other devices powered by the same supply.
4.2 General Safety Instructions for the operator
This section outlines the General Safety Instructions that must be observed by
the user to ensure safe operation.
• Read the operating manual before initial operation
• The device may only be connected to mains power outlets with a protective
earth (PE)
• The mains plug is a safe insulator of the power supply grid and must be
freely accessible at all times
• Do not start the device if it has a damaged power cable
• Do not operated damaged devices
• Only mount the circulator in suitable bath tanks or refrigeration units
• When connecting to external devices, observe the respective assembly
instructions, connection assignment of the plugs and technical data for the
products
• Observe the safety symbols on the device.
• Do not remove safety symbols
• Have all service and repair work carried out by authorized specialists only

Safety

Read operating manual before switching on
4.5 Safety function
Technical protective devices provide for safe operation. If a safety function is
triggered, the operator is alerted with a message on the display and an acoustic
signal.
Adjustable high temperature cut-off
The high temperature cut-off prevents overheating of the heater.
• If the temperature of the working temperature reaches the set protective
temperature, an error message appears on the display. The pump and
heater are switched off. A restart is required.

Safety
14
Overheating protection
The overheating protection prevents overheating of the heater.
• The protection mechanism responds when a certain temperature difference
between the working temperature sensor and the safety temperature sensor
is exceeded. A warning message appears on the display. The heating
capacity is limited.
• If the temperature difference persists for longer, an alarm message appears
on the display and the temperature control application is switched off.
Low liquid level protection
A level switch recognizes when the bath fluid fill level in the bath tank is too
low. The device has a two-stage warming system to prevent overheating of the
heater or dry running of the pump.
• The low liquid level warning is triggered when the liquid level in the bath
tank is about half the full level. A warning message appears on the display.
The bath fluid should be topped up.
• The low liquid level alarm is triggered when the float reaches its lower limit
stop. The device switches off the pump and heater. A continuous signal
tone sounds. A warning message appears on the display. A restart is
required.

temperature applications
5.2 Function description
This section describes the function of the device.
The circulator can be mounted on any bath tank with a volume up to 50 liters.
The circulators are used for internal and external temperature control, and
depending on the device combination and accessories used can work in a
temperature range between -50°C and +200°C.
When mounted on a bath tank the circulator is a heating circulator, when
combined with a cooling machine it is a refrigerated circulator.
