Intended use
1. Intended use
JULABO recirculating coolers have been designed for temperature application to specific
fluids. The pump connections can be used for cooling applications in an external circuit at a
constant temperature.
JULABO recirculating coolers are not suitable for direct temperature control of
foods, semi-luxury foods and tobacco, or pharmaceutical and medical
products. Direct temperature control means unprotected contact of the object
with the bath medium (bath fluid).
1.1. Description
The recirculating cooler consists of
control unit with splash-proof keypad (microprocessor technology)
cooling compressor
heater
heating/cooling bath and recirculating pump
The electronics comprises two microprocessors that provide reciprocal monitoring via
sensors for the working and safety circuit.
The actual and setpoint temperatures are permanently visible on the MULTI-DISPLAY (LED
1 + LED 2) and thus may be easily compared.
The bath tank is located in the lower part of the unit. The cooling machine draws heat from
the bath liquid via the cooling coil (evaporator). If the setpoint lies above the ambient
temperature, the integrated heater produces more heat.
The integrated circulating pump ensures constant conditions for the external cooling loop and
provides a good circulation of the liquid in the bath tank.
The unit provides analog electrical connections and a serial interface.
Safety installations: High temperature and low temperature limits, both adjustable via the
MULTI-DISPLAY, as well as low liquid level protection.
2. Operator responsibility – Safety instructions
The products of JULABO ensure safe operation when installed, operated, and maintained
according to common safety regulations. This section explains the potential dangers that may
arise when operating the recirculating coolers and also specifies the most important safety
precautions to preclude these dangers as far as possible.

Recirculating coolers
The operator is responsible for the qualification of the personnel operating the units.
The personnel operating the units should be regularly instructed about the dangers
involved with their job activities as well as measures to avert these dangers.
Make sure all persons tasked with operating, installing, and maintaining the unit have read
and understand the safety information and operating instructions.
When using hazardous materials or materials that could become hazardous, the unit may
be operated only by persons who are absolutely familiar with these materials and the unit.
These persons must be fully aware of possible risks.
If you have any questions concerning the operation of your unit or the information in this
manual, please contact us!

Safety recommendations for the operator
You received a product conceived for industrial use. Nevertheless, avoid strikes to the
housing, vibrations, damages to the keypad foil (keys, display) or contamination.
Make sure the product is regularly checked for proper condition. Regularly check (at least
every 2 years) the proper condition of the mandatory, warning, prohibition and safety
labels.
Take care that the mains supply features a low impedance to avoid any negative affects
on the instrument being operated in the same mains.
This unit is designed for operation in a controlled electromagnetic environment. This
means that transmitting devices (e.g. cellular phones) should not be used in the
immediate vicinity. Magnetic radiation may influence other units with components
susceptible to magnetic fields (e.g. a monitor). We recommend to keep a minimum
distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative air humidity: 50 % (40 °C).
Do not store in an aggressive atmosphere. Protect from contaminations.
Do not expose to sunlight.

Appropriate Operation
Only qualified personnel is authorized to perform configuration, installation, maintenance and
repairs of the water bath.
Routine operation can also be carried out by untrained personnel who should however be
instructed by trained personnel.
Use
For the use according to the intended purpose, special material requirements have to be
respected (bath fluids). Only use non-acid and non corroding materials.
5
Operator responsibility – Safety instructions
Observe all warnings for the used materials (bath fluids) and the respective instructions
(safety data sheets).
Only use the unit in well ventilated areas. The recirculating coolers are not for use in
explosive atmosphere
When using hazardous materials or materials that could become hazardous, the operator
must affix the enclosed safety labels (1 + 2) to the front of the unit so they are highly visible:
1
2
or

Observe the instructions in the manuals for instruments of a different make that you connect
to the recirculating cooler, particularly the corresponding safety instructions. Also observe the
pin assignment of plugs and technical specifications of the products.
2.1. Disposal

This unit contains the refrigerants R134a or R404A – at this time considered not to have any
negative effects on the ozone layer. However, during the long operating period of the unit,
disposal prescriptions may change. So only qualified personnel should take care of disposal.
Valid in EU countries
See the current official journal of the European Union – WEEE directive.
Directive of the European Parliament and of the Council on waste electrical
and electronic equipment (WEEE).
This directive requires electrical and electronic equipment marked with a
crossed-out trash can to be disposed of separately in an environmentally
friendly manner.
Contact an authorized waste management company in your country.
Disposal with household waste (unsorted waste) or similar collections of
municipal waste is not permitted!

Danger of corrosion of heat exchanger due to unsuitable quality of
cooling water.
Due to its high content of lime hart water is not suitable for cooling and
causes calcination of the heat exchanger.
Ferrous water or water containing ferrous particles will cause formation of
rust even in heat exchangers made of stainless steel.
Chlorous water will cause pitting corrosion in heat exchangers made of
stainless steel.
Due to its corrosive characteristics distilled and deionized water is
unsuitable and will cause corrosion of the bath. .
Due to its corrosive characteristics sea water is not suitable.
Due to its microbiological (bacteria) components which settle in the heat
exchanger untreated and unpurified river water and water from cooling
towers is unsuitable.
Avoid particulate matter in cooling water.
Avoid putrid water.
