  • Page 5: Operating Manual

    Operating manual Intended use JULABO circulators have been designed to control the temperature of specific fluids in a bath tank. The units feature pump connections for temperature control of external systems (loop circuit). JULABO circulators are not suitable for direct temperature control of foods, semi-luxury foods and tobacco, or pharmaceutical and medical products.

  • Page 6: Operator Responsibility - Safety Recommendations

    Operator responsibility – Safety recommendations 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.
  • Page 7 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. Use: The bath can be filled with flammable materials. Fire hazard! There might be chemical dangers depending on the bath medium used.

  • Page 8: Disposal

    Warning label W26: Colors: yellow, black Hot surface warning. (The label is put on by JULABO) Observe the instructions in the manuals for instruments of a different make that you connect to the circulator, particularly the respective safety recommendations. Also observe the pin assignment of plugs and technical specifications of the products.

  • Page 9: Ec Conformity

    24 months, limited to a maximum of 10 000 working hours. To apply for this extended warranty the user must register the unit on the JULABO web site www.julabo.de, indicating the serial no. The extended warranty will apply from the date of JULABO Labortechnik GmbH’s original invoice.
