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. -

Page 20: Filling/Draining
Preparations 5.4. Filling/draining Notice Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of the liquid. Do not drain the bath fluid while it is hot or cold! Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example). -
Page 21: Operating Procedures
Entry of ice flakes/water into the bath oil At working temperatures below 0 °C, humidity from the atmosphere may enter the bath oil through condensation. This may subsequently result in the formation of ice flakes, impairing the operation of the pump. For this reason, the bottom of the bath tank provides a groove sloping down towards the drain tap. -

Control of the FP89 cooling machine: The mains switch is turned on. After pressing the start/stop button, the cooling machine is automatically switched on or off by the circulator. In the start mode of the circulator, the cooling machine runs continuously. Immediately after starting the cooling machine, the output of the system is reduced to a minimum value for a defined period in order to equilibrate the cooling system. -
