APPENDIX 6
VACUUM TEST
Use this test to validate the performance of the sterilizer in terms of leakage. During the test the following is
checked:
•
Efficiency of the vacuum pump.
•
Tightness of the pneumatic circuit.
The cycle profile specific for this test
includes:
•
A vacuum phase up to P1 (-0.87 bar).
•
A stabilization period of 5 min.
=> T2. Reading of P2.
•
A testing period of 10 min.
=> T3. Reading of P3.
The microprocessor makes the following calculation: P3 - P2. The result must be less than 0.013 bar.
How to carry out the test:
Select and initiate the Vacuum Test cycle from the "Test cycles" submenu.
A display message will inform at the end of the test cycle if the test passed or failed. If the test failed,
check, clean or replace the door gasket, clean the chamber face side and repeat the test. If the test fails
repeatedly call technical service. Follow local/national guidelines on the frequency of testing.
When performing a Vacuum Test, the sterilizer chamber must be completely dry
and cold. By not following this instruction, the Vacuum Test might fail even if the
sterilizer works properly.
