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 water baths are not suitable for direct temperature control of foods, semi­luxury 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 coolers are operated via the splash-proof keypad. The
implemented microprocessor technology allows to set and to store the setpoint that
PID1
RS232
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.
Electrical connections:
1. The serial interface RS232 allows modern process technology without additional interface.
2. Alarm output for external alarm message.
Manually adjustable by-pass (handwheel) to reduce the pump capacity
(e. g. for glass equipment).
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 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. 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. Observe all warnings for the used materials (bath fluids) and the respective instructions (safety data sheets). Only use the unit in well ventilated areas. (see page 16). 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:

or 2
Observe the instructions in the manuals for instruments of a different make that you connect to the circulator, particularly the corresponding safety instructions. Also observe the pin assignment of plugs and technical specifications of the products.
Warning label W00: Colors: yellow, black Danger area. Attention! Observe instructions. (operating manual, safety data sheet)
Mandatory label M018: Colors: blue, white Carefully read the user information prior to beginning operation. Scope: EU
Semi S1-0701 Table A1-2 #9 Carefully read the user information prior to beginning operation. Scope: USA, NAFTA

2.1. Disposal
This unit contains the refrigerantr R404A, which at this time is not considered harmful to the ozone layer. However, over the long operating period of the unit, disposal rules may change. Therefore, only qualified personnel should handle the 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 crossed­out 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!
