Product Features:1. Confirm that the air tank connection valve is in the closed state2. Connect the liquefied petroleum gas interface inflation valve to the gas cylinder, unscrew the gas cylinder valve for leakage, and check the interface to ensure safety3. The liquid gas cylinder is upside down4. Connect the empty tank to the flat gas connection valve, open the cylinder knob, and then observe the flow of liquefied gas in the pipe5. The flat tank is connected to the inflation valve on the electronic scale. In general, a flat tank cannot be tared and weighed because sometimes a flat tank can remain so if the flat tank is peeled it can be overloaded. Observe the filling quantity in real time during the filling process. The suggestion is to have less than the original water tank6. The inflation tube inflation valve will take the remaining liquefied liquid gas, then just connect the inflation valve to the flat tank, close the liquefied gas cylinder valve, open the flat tank inflation valve, and the gas remaining in the liquefied gas pipe will automatically flow into the flat tank, filling the LPG valve residueSpecification:* Material: PU+Metal high pressure hose * Size: 43.5*5cm(Approxi)Package List:1 * Air Tank Valve InflationNote:1.
