1. Turn off the air source and remove the hose.
2. Put the wire, DN15 solenoid valve, pagoda head and clamp in order.
3. Install and connect the wire with DN15 solenoid valve, pagoda head and clamp (for hose, not for alum-plastic pipe) in turn, please be sure to tighten the screws. To prevent gas leakage, the head of the pagoda and the ends of the wire should be wrapped with raw tape several times before being connected.
4. Open the air source and smear it on the pipe interface with soap and water to see if there is any bubble. If yes, please turn off the air source and redo Step 3.
5. Connect the solenoid valve connecting line and gas alarm.
