1. First, take out the inner sterilization bucket of the pressure steam sterilizer, and then add an appropriate amount of water to the outer pot to make the water surface level with the triangular shelf.

2. Put it back into the sterilization bucket and load the items to be sterilized. Be careful not to pack too much, so as not to hinder the flow of steam and affect the sterilization effect.

3. Put the cap on, and insert the capped exhaust hose into the exhaust slot of the inner sterilization barrel. Tighten the opposite two bolts at the same time in a symmetrical manner, so that the bolts are tight and consistent, and do not leak air.

4. Turn on the power to heat, and at the same time open the vent valve to boil the water to remove the cold air from the pot. After the cold air is completely exhausted, close the exhaust valve and let the temperature in the pot gradually rise as the steam pressure increases. When the pressure in the pot rises to the required pressure, control the heat source and maintain the pressure for the required time.

5. When the time required for sterilization is up, cut off the power of the pressure steam sterilizer or turn off the gas, and let the temperature in the sterilizer drop naturally. When the pressure of the pressure gauge drops to 0, open the exhaust valve, loosen the bolt, open the lid, and take out Sterilize items.
