  1. Remove the tubing from it's shipping container, and any additional packing that may be on or around the tubing.
  2. Place tubing on an oven rack, suitable for ovens 1-4. Tubing should be spaced evenly on each shelf, appoximately 16 tubes per shelf. After loading the rack into the oven, make sure the tubes are not touching each other, the oven walls, the oven door, or the sides of the oven rack.
  3. Select and run oven program: PEEK1
  4. After the temperture has peaked and cooled down to below 250F, the oven's circulation fan may be turned off. When temperatures fall below 150F the doors may be opened and the tubing removed.
  5. Allow tubing to cool to room temperature before painting one end with Layout Dye. Do not attempt to chill the tubes in order to make them usable sooner. Move to machining area when cooled.
