  • Page 10: Safety Instructions

    SAFETY INSTRUCTIONS The autoclave has unique characteristics. Please read and understand the operation instructions before first operation of the autoclave. The following issues may require instructions guidance provided by the manufacturer: how to operate the autoclave, the door safety mechanism, the dangers involved in circumventing safety means, how to ensure that the door is closed, and how to select a correct sterilization program.
  • Page 11 Open the door slowly to allow steam to escape and wait 5 minutes before you remove the load. When sterilizing liquids, wait 10 minutes. Once a month, ensure that the safety valves are functioning, and once annually a certified tester must conduct pressure chamber safety tests. Once annually, or more frequently, effective tests must be performed, i.e., calibration and validation.

  • Page 12: Technical Data

    TECHNICAL DATA Stand – by heating mode The autoclave provides an option of heating the chamber in stand-by mode between cycles with a very low power in order to reduce total cycle time (1.6% of the total power only). The autoclave turns off automatically if the interval between the sterilization cycles is more than 2 hours.
