After the electric pressure cooker is completed, The heat insulation lamp will illuminate(yellow),at this point, Electric pressure cooker has been completed。The pressure inside the machine will gradually decline after entering the insulating layer.,When pressure drops to normal atmospheric pressure Machine can open the cover normally。usually, There is no pressure, the float valve on the pot will drop(Push the float valve upwards when there is pressure); LSThe series also has a pressure indicator when the indicator is turned off., This means no pressure; LZDisplay with pressure display,Signal similar to a mobile phone signal,Small display, The lower the 易彤破壁料理机售后 pressure。Disappearing when there is no pressure。Sometimes there is no pressure in the pot,The float valve may not fall,The cover cannot be opened。This may be because the float valve is called.,at this time, It is recommended that users re-energize and heat a few minutes.,Then reduce the pressure again; Or use a wooden stick to move the lower floating ball valve,but,Do not close your head or face or align the exhaust port,In order to prevent the gases in the pan from ejecting and burns the user。Open mode:Quick open mode(For non-liquid objects):Set the exhaust valve in the exhaust position,Let the gas come out from the pot until the float valve falls; note:Some products do not have exhaust valves,Removal and decompression through fan interior; Natural cooling method(Suitable for liquid objects):Let the machine cool,Until the float valve falls,You can also cover your lid with a wet towel to speed up the cooling speed.,Until the float valve。It is strictly forbidden to use a fast opening method using a liquid object,Because there is pressure in the pot if there is direct opening of the exhaust door,Food will flow from the exhaust valve port。
