8. Slide the vessel lid closed and insert bolts. The bolts only need to be engaged a turn or two. It is not necessary at
this time to completely tighten the bolts. Close the oven lid and secure using the latches.
9. Press the “Preheat” button. The system should change the status display to “Preheat” and the temperature should
slowly start to rise.
10. Wait until the status display changes to “Load Samples” it will do this when the vessel is at the age cycle
temperature and stable. This is a good time to get your samples ready if you have not already done so.
11. When the status display changes to “Load Samples” open the oven lid by unlatching the latches. Unbolt and open
the vessel lid. Carefully remove the specimen holder from the PAV as it will be very hot.
12. Load specimens into the rack. Load all ten pans into the sample holder even if there are not ten samples to age.
13. Quickly and carefully return the sample holder to the PAV. The vessel temperature will decrease when the oven
and vessel lids are open. To avoid a long temperature recovery, attempt to load the PAV and secure the vessel and
oven lids as quickly and as safely as possible.
14. Close the vessel lid and secure the bolts according to the diagram. Tighten in sequential order with the wrench
provided. Go around twice to tighten bolts to 55 inch/pounds.
15. Once the vessel lid is secured, close the oven lid and secure with latches.
16. Press the “Age Cycle” button immediately, DO NOT WAIT for the temperature in the PAV to recover to the age
setpoint. The status display should change to “Recovery / Pressurizing”. Be mindful of the pressure setpoint.
17. Once the temperature and pressure are stable the status display will change to “Aging Cycle” and the remaining
time will be displayed.
18. When the age cycle time has expired the status display will change to “Aging Finished”.
