    Introduction Chapter 1 OPERATION MANUAL Safety information and procedure The safety information in this operation manual is designed to protect the operating company, the operator and the equipment from damage. First inform yourself about any residual risks due to misuse before you start an operation. 1.3.2 Representation of safety identifiers on the temperature control unit The following pictograms are used as safety identifiers.

  • Page 14: Reasonably Foreseeable Misuse

    Flow-through coolers and calibration baths must be used only in com- bination with Huber temperature control units. Only use thermal fluids suitable for the overall sys- tem. The cooling or heating capacity is provided at the pump connections or - where present - in the tempering bath.

    ▪ Your system, which uses our temperature control unit, must be equally safe. ▪ The responsible body must design the system to ensure it is safe. ▪ Huber is not responsible for the safety of your system. The responsible body is responsible for the safety of the system.
  • Page 16 OPERATION MANUAL Chapter 1 Huber temperature control units are constructed to be permanently sealed and are carefully checked for leak tightness. Temperature control units with more than 150 g natural refrigerant are equipped with an additional gas warning sensor. To find out whether your temperature control unit is equipped with a gas warning sensor, refer to the data sheet.
  • Page 17 Introduction Chapter 1 OPERATION MANUAL The operator is responsible for the calibration of the gas detection sensor prior to initial operation and the observance of calibration and maintenance intervals according to the operating manual. We recommend to set calibration and maintenance intervals between 6 and 12 months if no information is provided.

  • Page 29 Chapter 2 OPERATION MANUAL To minimize cooling water consumption, Huber temperature control units with water cooling are equipped with a cooling water regulator. It limits the flow of cooling water to the amount required by the current load situation. If only a low cooling capacity is requested, only a small amount of cooling water is consumed. It cannot be ruled out that cooling water flows when the machine is switched off.
