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, 14
and 15).
They are protected by a safety shield.
In order to prevent the safety valve from a blockage, operate it once a
month.
Attention:
Use protective gloves in order to prevent hot steam burns to hands
