1, food and water can not be filled too full, preferably less than two-thirds; When capping, the upper and lower three can be aligned, screw into the groove, until the upper and lower handles are aligned, after the fire, see the steam stably emerging from the exhaust pipe, in order to timely buckle the pressure limiting valve, the pressure limiting valve can not be pressed on other items, let alone other items to replace the pressure limiting valve. When the pressure limiting valve is lifted by the steam impulse and a hissing sound is heard, the heat should be reduced immediately until the food is cooked.
2, it should be noted that after turning off the fire, it is necessary to wait for the pot to cool down and then take the lower pressure valve and open the lid, otherwise it may be because the pressure in the pot is too large and the lid will rush up, and risk will occur. If you are eager to eat, you can use warm or cold water slowly poured on the lid to force cooling, but natural cooling is the best.
3, and the pressure limiting valve you may use a thin stick through the three holes, can see the stick in the middle of it is smooth. There is also the rubber ring in the electric pressure cooker, which is an important part to ensure the good tightness of the electric pressure cooker, and don't forget to replace it regularly. Usually when washing the rubber ring, it is best to wash with running water together with the pot cover, to wash the residual particles and residue attached to the rubber ring, do not take it off to wash alone, to avoid stretching the rubber ring and affecting the sealing.
4, usually don't forget to carefully maintain your electric pressure cooker. We recommend that you carefully clean the air holes and pressure limiting valves and safety valves after each use of the electric pressure cooker. Open this, this is to prevent blocking, looking at the sun, the safety valve with hand push, can move it means that there is no blocking.
