
Slow Exhaust: Steam is exhausted from the chamber at a slow rate,
until it reaches the pressure of 30 kPa above the ambient pressure.
Then steam is exhausted out of the chamber at a fast rate until
pressure decreases to ambient pressure.
Note : If the cycle fails, fast exhaust is performed through the bio-hazard
filter. Some water may remain in the chamber after a failed cycle. To
remove such water, press Start and repeat the cycle. If the problem
persists, call for service.

Drying: N/A

Ending: The system checks that End temperature and End pressure
have been reached, and then releases the door.
5.12 Program 12: Vacuum Test (PV, pre-vacuum models
only)
Vacuum Test is a test program with the following parameters:
Nominal parameters default settings

Vacuum pressure: 17.0 kPa

Vacuum time 1: 5 minutes

Vacuum time 2: 10 minutes
Operations sequence:

Vacuum is produced in the chamber down to P1=17 kPa. At this
stage all the valves close. The autoclave remains in this stage for 5
minutes. This period enables the condition in the chamber to reach
equilibrium.

After the 5 minutes have elapsed, the printer records the pressure
that is referred to as P2. At this point the test begins and lasts 10
minutes.

At the end of the test, the printer records the results. The pressure at
the end of the test is referred to as P3. The rate of change of P3-P2
shall not exceed 0.13 kPa/min.).
