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 Safety instructions
The unit is built in accordance with state of the art technology and recognized
safety regulations. Despite this, its use may pose a risk to life and limb for the
user or third parties.
Therefore, always read and observe the following safety instructions before
using the product.
Hot surfaces!
The following parts and elements may become hot during operation:
– Bath fluid
– Heating element
– Bath lid
– Bath surface
– Connections for external application
Contact may cause severe burns or scalds to hands and arms, face and limbs.
• Keep sufficient distance from hot surfaces and fluids.
• Wear suitable protective gloves.
Electric shock from electrical system!
Touching damaged live parts can cause severe electric shocks and lead to injury
or even death.
• Have damaged insulation and parts of the electrical system immediately
repaired by JULABO service technicians or a qualified specialist workshop
• Immediately replace damaged power cords
• When connected with a mains plug, this mains plug must always be readily
accessible
Refrigerants are harmful to health!
Refrigerants and their vapors are harmful to health. There is a suffocation risk in
enclosed spaces.
• Do not touch or inhale refrigerants.
• Have damage to the refrigerant cycle repaired only by JULABO service
technicians or qualified specialists.
• If refrigerant leaks, stop the device immediately and ventilate the room
thoroughly.

Safety
11
Natural refrigerants are flammable!
The device contains flammable refrigerants. If there is a leak in the refrigerant
cycle, a flammable concentration may form in the air and ignite or explode. This
can result in serious injury or death.
• Use the required minimum room size for operating the device.
• Do not store any potential sources of ignition near the device.
• If refrigerant leaks, stop the device immediately and ventilate the room
thoroughly.
• Have damage to the refrigerant cycle repaired only by JULABO service
technicians or qualified specialists.
• Have maintenance work performed only by JULABO service technicians or
qualified specialists.
Wear personal protective equipment!
Lacking or unsuitable personal protective equipment increases the risk of health
damage and injury.
Personal protective equipment includes, for example:
– Work gloves
– Safety shoes
- Protective clothing
– Breathing protection
- Hearing protection
– Face and eye protection
• Specify and provide personal protective equipment for the respective
application.
• Use only personal protective equipment that is in good condition and
provides effective protection.
• Adapt personal protective equipment to the person, e.g., by size.
Keep safety symbols legible!
Safety symbols on the unit warn of dangers in hazardous areas and are an
important part of the unit’s safety equipment. Missing safety symbols increase
the risk of injury to persons.
• Clean dirty safety symbols.
• Replace damaged and unrecognizable safety symbols immediately.
Maintenance and repair work!
Improper maintenance and repair work jeopardizes operational safety. This can
result in serious injury or death.
• Only carry out work described in this operating manual. Switch off the unit
and disconnect it from the power supply before carrying out any work.
• All other maintenance and repair work may only be carried out by a JULABO
service technician or a qualified specialist workshop.

4.3 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 measured temperature rises above the set protective temperature, an
error message is shown on the display. The pump and heater are switched
off. A restart is required.
Overheating protection
The overheating protection prevents overheating of the heater.
• The protective mechanism is triggered when the device recognizes a
temperature difference of more than 20 K between the working
temperature sensor and the safety temperature sensor. Am error message
appears on the display. A restart is required.
Low liquid level protection
A level switch recognizes when the bath fluid fill level in the bath tank is too
low. The unit has a warning system to prevent overheating of the heater or dry
running of the pump.
• 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. An error message appears on the display. A restart is required.
