Precautions of FDF4A10 series pilot normally closed type solenoid valve:
1) For the matching characteristics of the system, please confirm the test first.
2) For air conditioners equipped with solenoid valves, be sure to install a filter of 100 mesh or more before and after the valve.
3) When assembling the welding piping, be sure to ensure that the valve body temperature does not exceed 120 °C.
4) Keep the valve dry and clean during installation.
5) Solenoid valve body and coil must be used together.
6) After the coil and the valve body are assembled, they need to be snapped into place.
7) Before using the product, please confirm whether the model, voltage, etc. meet the system matching requirements, and avoid the failure of the coil to burn due to the wrong use.
8) The instruction manual is included in the product package. If you have any questions, please contact the sales staff.
