Congratulations! You have made an excellent choice. JULABO thanks you for the trust you have placed in us. This operating manual has been designed to help you gain an understanding of the operation and possible applications of our circulators. For optimal utilization of all functions, we recommend that you thoroughly study this manual prior to beginning operation.
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.
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.
