    INSTALLATION EQUIRED MBIENT ONDITIONS These units are built for use indoors, at room temperatures between 15°C and 35°C (59°F and 95°F), at no greater than 80% Relative Humidity (at 25°C / 77°F). The ambient temperature should not change by 2°C (3.6°F) or more during operation. Operating outside these conditions may affect the oven temperature performance.

  • Page 19: Power Source Requirements

    Switch or circuit-breaker: A wall switch or circuit-breaker must be used in the building installation to protect against overcurrent conditions. The recommended circuit-breaker for the wall power source for the SVO-5-T-1P is 50 amps. • Power Feed Disconnect: The oven must be positioned so that all operators have access to the power feed disconnect in case of emergencies.

  • Page 35: 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 36 OPERATION Turbomolecular Pump Hazards and Precautions Fragmentation Hazards Turbopump blades spin at tens of thousands of rotations per minute in a nearly friction-free environment with ultra-tight tolerances inside the pump housing. Catastrophic damage may result if the oven turbopump suffers a significant impact or is moved while the blades are spinning. A sudden and large internal pressure increase while spinning can also induce a catastrophic failure.

  • Page 39 OPERATION Nitrogen Precautions Required PPE Ensure all oven operators have received training and that proper personal protective equipment • (PPE) for handling liquid nitrogen is on hand. Personnel handling liquid nitrogen containers must utilize personal protective equipment. • This includes personnel connecting the oven to an LN supply source.

  • Page 40: Theory Of Operation

    OPERATION HEORY OF PERATION From Room Pressure to High Vacuum The oven chamber is initially pumped down by a roughing pump located in the cabinet beneath the chamber. The roughing pump runs continuously while the oven is powered, but it will not draw atmosphere from the chamber until the Start Vacuum button is pushed.
  • Page 41 OPERATION Vacuum Safety Interlocks continued If the chamber pressure rises above 1 Torr while the turbopump is active, the oven will close the gate valve and foreline valves, isolating the pump from the chamber. The oven will then open the pneumatic roughing valve, allowing the roughing pump to vacuum down the chamber down below 1 Torr.
  • Page 42 OPERATION Controlling Temperature The oven uses two major systems to control temperature. The oven chamber wall system employs heating elements built into the chamber walls. The platen thermal shelf is built with both internal heating elements and channels for pulsing liquid nitrogen (LN ).

  • Page 50: 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 38 for a list of precautions for handling LN when connecting the supply to the oven.

  • Page 58: 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.
