  • 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: 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.
