  • Page 37: 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 40: Theory Of Operation

    OPERATION HEORY OF PERATION Vacuum and Vacuum Automation Atmosphere is pumped out of the oven chamber through a pneumatic vacuum valve on the back of the oven and then exits through the roughing vacuum pump connected to the valve. The valve position is controlled by either the Full Vacuum or Vacuum Control functions.
  • Page 41 OPERATION Heating in a Vacuum In conventional ovens, powered elements transfer heat into the chamber air. The heated air then circulates by natural convection or blower fan action, surrounding the product on the shelves and gradually bringing it to temperature. In a vacuum oven, heat transfer takes place in part through infrared radiation.

  • Page 47: Pump Down The Oven Chamber

    OPERATION OWN THE HAMBER Note: Perform a Full Vacuum pump down of the chamber for at least 10 minutes when first putting the oven into operation in a new location to verify the vacuum supply system integrity. Operator Must be Present: An operator must always be present to observe the vacuum gauge pressure display decreasing while the oven is drawing a vacuum to ensure the system is sealed.
  • Page 48 OPERATION Option 2 – Manual Vacuum Control Pumps down the oven chamber to a setpoint between room pressure and 1 Torr. Entering a vacuum level setpoint. Turning on the vacuum pump and then the Vacuum Control function. The oven then pumps down to the vacuum level setpoint. Procedure Steps 1.

  • Page 50: Backfilling The Chamber

    OPERATION ACKFILLING THE HAMBER Atmosphere is restored to the chamber in two stages. Stage 1: Automatic Partial Backfill The oven automatically closes the vacuum valve and partly backfill the oven chamber to approximately 600 Torr when one of two trigger events takes place. Manual Backfill Trigger The oven partially backfills the chamber whenever both the vacuum functions have been manually turned off.

  • Page 51: Connect To The Liquid Nitrogen Supply

    OPERATION ONNECT TO THE IQUID ITROGEN UPPLY The oven manufacturer recommends waiting to connect an LN supply to the oven until just before launching a temperature process that requires chilling. This helps minimize LN hazards in the workspace. See page 39 for a list of precautions for handling LN when connecting the supply to the oven.

  • Page 52: Manually Setting Constant Temperature Setpoints

    OPERATION ANUALLY ETTING ONSTANT EMPERATURE ETPOINTS Constant temperature setpoints run the oven or platens at steady state temperatures and are manually set and adjusted by the oven operator. Reminder: The manufacturer recommends fully vacuuming down the oven chamber before heating or chilling.

  • Page 60: Maintaining Atmospheric Integrity

    MAINTENANCE AINTAINING TMOSPHERIC NTEGRITY Periodically, inspect the door latch, trim, catch, and gasket for signs of deterioration. Failure to maintain the integrity of the door system shortens the lifespan of the unit. ASKETS The door gasket is a low-wear item. It typically only needs to be replaced due to being cut or nicked. The risk of this type of damage can be significantly reduced by opening the door to 130°, keeping it well out of the way of shelves or sample trays being removed from or inserted into the chamber.
