  • Page 5: Operating Manual

    Recirculating Cooler Operating manual Intended use JULABO recirculating coolers 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 recirculating coolers are not suitable for direct temperature control of foods, semi-luxury foods and tobacco, or pharmaceutical and medical products.
  • Page 6 Operator responsibility – Safety instructions 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.

  • Page 7: Disposal

    There are thermal dangers: Burn, scald, hot steam, hot parts and surfaces that can be touched. 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 corresponding safety instructions.
