Using the sterilizer
5.4.1 Vacuum test
Adhere to national and local guidelines regarding testing
frequency.
The purpose of the Vacuum test is to ensure that the sterilization chamber
is perfectly sealed. The manufacturer recommends running the test at
the start of the day, before beginning the daily sterilization cycles.
The Vacuum test is activated with the machine unloaded, in standby
mode and at an internal temperature below 35°C, which are the typical
conditions of the state of the device at the start of a working day.
Press the TEST button;
In the Test menù, press the VACUUM button;
If you want to program the Vacuum cycle, click the blue button highlighted on the screen,
otherwise if you want to start the test immediately, press the START button.
The device starts automatically the Vacuum test, which lasts approximately 15 minutes. In
case of negative test result, the display turns red, and the alarm code indicating an inadequate
chamber condition is displayed (see to the ‘Alarms’ chapter).
5.4.2 Helix test and Bowie & Dick test
The purpose of Helix test and Bowie&Dick test is to verify the proper penetration of the
sterilising steam in the tools contained in the sterilization chamber.
The Helix test and Bowie&Dick test are activated with the sterilizer switched on.
The manufacturer recommends running these tests at the start of the day, before beginning the
daily sterilization cycles, but they can be run at any time, with the sterilizer on.
Prepare the sterilizer for a Helix test (e.g. HTS100 class 5 cod. 9900051) or a Bowie&Dick test
(e.g. 3MTM COMPLYTM cod. 1300) in accordance with the requirements of the test procedure
regulations.
The device automatically starts the test program, with a temperature of 134°C, a sterilization time of 3.5 minutes
and 3 vacuum phases.
If an undesired Helix test or Bowie & Dick test is accidentally started, you can stop it by pressing the STOP button.
The device deletes the test started unintentionally, automatically initiates a procedure to remove the fluids in
circulation and places itself in stand-by, ready for use in a normal working cycle.
5.5 Preparing the material before sterilization
5.5.1 Preliminary operations
All the material to be prepared for sterilization is normally contaminated.
Before handling or moving contaminated materials or instruments, the following precautions should be taken:
Wear rubber or latex gloves of suitable thickness and a face mask;
Wash your hands, with the gloves already on, using a germicidal detergent;
separate the instruments suitable for sterilization from those that are not;
do not carry contaminated instruments in your hands, but always use a tray suitable for carrying instruments;
be very careful of instruments with sharp parts that can puncture normal rubber gloves; in such cases, protect
your hands with gloves of sufficient strength;
once the handling and transfer of the contaminated materials is finished, carefully wash your hands while still
wearing the gloves.
