Pressing start runs the full fill, sterilize, exhaust and dry cycle from a built-in water tank, with no external water connection, at up to 34.8 PSI (2.4 bar). Preset programs cover liquids, wrapped instruments and unwrapped instruments or plasticware, a Dry Only option extends drying, and every parameter can be adjusted. A mechanical and electrical interlock keeps the door closed until pressure reaches zero.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e28 L stainless steel chamber, 34.8 PSI (2.4 bar) maximum pressure\u003c\/li\u003e\n\u003cli\u003eOne-button automatic fill, sterilize, exhaust and dry cycle\u003c\/li\u003e\n\u003cli\u003eBuilt-in water tank;
