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.
PID1

The recirculating coolers are operated via the splash-proof keypad.
The implemented microprocessor technology allows to set and to
store the setpoint that can be indicated on the LED temperature
display.
The PID temperature regulation is used to withdraw heat from the
bath fluid by means of the cooling machine and to automatically
regulate the required need.
Health hazards caused by the bath fluid.
JULABO recirculating coolers are not conceived for direct temperature
application to food and luxury articles or pharmaceutical and medico-
technical products.
Direct temperature application means: Unprotected contact of the object with the bath
medium (bath fluid).
2. Operator responsibility – Safety recommendations
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 circulator and also specifies the most important safety precautions to
preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
Make sure that the persons who operate the chillers, are trained in this work.
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 circulator
may be operated only by persons who are absolutely familiar with these materials and the
circulator. These persons must be fully aware of possible risks.

3. Handling
You have received a product designed for industrial use. Nevertheless, avoid strikes to the
housing, vibrations, damage to the operating-element panel (keypad, display), and
contamination.
Make sure the product is checked for proper condition regularly (depending on the
conditions of use).
Regularly check (at least every 2 years) the proper condition of the mandatory, warning,
prohibition and safety labels.
Make sure that the mains power supply has low impedance to avoid any negative effects
on instruments being operated on 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 affect other devices with components sensitive to magnetic fields
(e.g., monitors). We recommend maintaining a minimum distance of 1 m.
Permissible ambient temperature: max. 40 °C, min. 5 °C.
Permissible relative humidity: 50% (40 °C).
Do not store the unit in an aggressive atmosphere.
Protect the unit from contamination.
Do not expose the unit to sunlight.
3.1. Appropriate operation
Only qualified personnel is authorized to perform configuration, installation, maintenance and
repairs of the circulator.
Routine operation can also be carried out by untrained personnel who should however be
instructed by trained personnel.
3.2. Use
Fire hazard!
The unit is not for use in explosive atmosphere.
The bath can be filled with flammable materials. Fire hazard!
There might be chemical dangers depending on the bath medium used.
Observe all warnings for the used materials (bath fluids) and the respective instructions
(safety data sheets).
Insufficient ventilation may result in the formation of explosive mixtures. Only use the unit in
1.951.4806-V2 5

Handling
well ventilated areas. The unit is not for use in explosive atmosphere.
Only use recommended materials (bath fluids). Only use non-acid and non corroding
materials.
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
Danger area. Attention! Observe instructions.
(operating manual, safety data sheet)

or
Carefully read the user information prior to beginning operation.
Scope: EU
2b
Carefully read the user information prior to beginning operation.
Scope: USA, NAFTA
3.3. Disposal
This unit contains the refrigerants R134a – 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!
