See page 44 for how to display other units of measurement or zero the gauge to your local altitude.

  • Page 33: Operation

    OPERATION Safe operation of the oven is dependent on the actions and behavior of the oven operators. Operating personnel must read and understand the Operating Precautions in this section prior to operating the oven. The operators must follow these instructions to prevent injuries and to safeguard their health, environment, and the materials being treated in the oven, as well as to prevent damage to the oven.

  • Page 34: Theory Of Operation

    OPERATION HEORY OF PERATION Vacuum Vacuum is supplied by an external vacuum supply (a pump or building system) connected to the vacuum port on the back of the oven. Vacuum levels obtained in the oven chamber are dependent on pump type and performance, valve settings, and the nature of the application or process, including the volume of outgassed materials.
  • Page 35 OPERATION Heating in a Vacuum In conventional ovens, powered elements transfer heat into the chamber air. The hot air then circulates by natural convection or blower fan action, surrounds the product on the shelves, gradually bringing it to temperature. In a vacuum oven, heat transfer occurs in part through direct infrared radiation.
