10.2 VACUUM TEST CYCLE
The VACUUM TEST cycle allows testing perfect seal of the sterilizer hydraulic system.
Measuring the variation of the degree of vacuum in a defined time-frame and comparing it with pre-established limit
values, you can determine how good the seal of the sterilization chamber, tubes and the various interception devices are.
1.
To select the VACUUM TEST cycle, press the
corresponding button and then press Start.
The cycle must run with the sterilization chamber
empty, and only the trays and their supports
inserted.
We suggest running this test at the beginning of each working
day with chamber at ambient temperature.
A high chamber temperature affects the variation
in the vacuum value measured during the test;
the system is therefore programmed to prevent
execution of the test when the operating conditions
are inadequate.
2.
Close the door and start the program.
The vacuum phase starts immediately and the
pressure value (bar) and the countdown from the
start of the test cycle are shown on the display.
If the pressure variation exceeds the limit defined, the program is interrupted and an alarm message generated.
For the complete description of the alarms refer to the appendix.
10.3 VACUUM TEST + B&D CYCLE
1.
Select this option to run a VACUUM TEST cycle and
a B&D cycle in sequence.
To this end, place the test device on the central tray
without inserting other material.
2.
Close the door and start the cycle.
The program will execute the two cycles in
succession.
Check the results as described in the previous
paragraphs.
The presence of the Bowie & Dick test device does not alter the execution and the result of the Vacuum test cycle.
