

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.

 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 14). 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 to the front of the unit so they are highly visible:

If this unit is intended for use within the United States of America, all 3 warning labels must be affixed to the housing of the unit prior to use. Directions for the positioning of the individual warning labels are enclosed with the warning labels included in the delivery. Warning labels must be easily visible to users.

Danger area. Attention! Observe instructions. (operating manual, safety data sheet)

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.

Carefully read the user information prior to beginning operation. Scope: EU

Carefully read the user information prior to beginning operation. Scope: USA, NAFTA

2.1. Disposal

This unit contains the refrigerants R452A or R404A, which at this time are 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.
