5.     Load your jars, bags, or media.
6.     Close the lid by turning the hand wheel knob tightly.
7.     Set temperature to 121°C (250°F) and select your sterilization time:

   2.     Grain jars: 90 minutes
8.     The timer begins once the set temperature (equivalent to 15–17 PSI) is reached.
9.     Once complete, the unit beeps to let you know it’s ready.
