Pressure Relief Valve
Location / Function / Testing
e pressure relief valve opens if the pressure inside the chamber
reaches 40 psi (275 kPa). When the valve opens, pressurized steam is
released from the bottom of the sterilizer thru the relief valve tubing.
e valve can be opened manually by pulling the pressure relief
handle located on the top cover
Caution
Steam / water will be expelled during this test.
To prevent burns, place a towel around the bottom of the sterilizer.
