1. Confirm the connection/wiring. Make sure the connection is correct after wiring.
2. Working voltage. When the power is connected to the solenoid valve, be careful to use the appropriate voltage. Improper voltage can cause failure or coil burn out.
3. Guide the valves in correct pressure. Because of outgoing disturbance and external pressure, make sure not to use more than 20N force on the guide valve/pneumatic valve, otherwise it will cause damage.
