12.5 Checking the Safety Valve
Both safety valves, the chamber safety valve (2) and the generator
safety valve (3), are located on the top rear of the autoclave (see Rear
View).
In order to prevent the safety valve from becoming blocked, it is
necessary to allow the steam pressure to escape through it (every
month).
To avoid injuries begin this check while the autoclave is cold.
1. For the autoclave safety valve, operate the sterilization cycle; for the
generator safety valve, operate the generator.
2. Allow a pressure of approximately 200 kPa (29-psi) to build up in the
chamber.
3. Remove water reservoir cover (1).:
 For ASME-approved safety valve: pull the ring of the safety
valve using a tool, i.e. screwdriver, hook etc and lift the safety
valve ring for 2 seconds. Be careful not to burn your hands.

For PED-approved safety valves: Turn the pressure relief nut
clockwise until steam ceases to escape from the safety valve.
5. Press the STOP key to abort operation, and allow the steam to exhaust
from chamber.
6. Wait until pressure goes down to zero, only then can the door be
opened.
