11.4 Checking the Safety Valve
To prevent the safety valve from blockage, it is necessary to allow the
steam pressure to escape through it (every month).
The safety valve is in the rear top side of the autoclave.
PED-approved type safety valve
1. Operate the sterilization cycle according to the manual.
2. Allow a pressure of approx. 200 kPa (29-psi) to build up in the
chamber.
3. Turn the pressure relief nut counterclockwise for 2 seconds. Verify
steam escapes from the valve.
Attention:
Use protective gloves in order not to burn your hands with the hot
steam.
4. Press the STOP key to interrupt the operation, and exhaust steam from
the chamber.
5. Wait until the pressure decreases to zero, only then can the door be
opened.
