1 the installation should pay attention to the arrow on the valve body should be consistent with the medium flow. There can not be installed in direct dripping or splashing water. Solenoid valve should be installed vertically upward.
2 solenoid valve should ensure that the supply voltage is the rated voltage fluctuation range of 15% -10% of normal work.
3 Solenoid valve is installed, the pipeline must not have reverse pressure differential. And the required power for several times, so that proper temperature before officially put into use.
4 Solenoid valve piping should be thoroughly cleaned before installation. Pass into the media should be free of impurities. Valve pre-installed filters.
5\When the solenoid valve malfunction or cleaning, to ensure the system continues to run, you should install the bypass device.
Failure and elimination:
(1) Solenoid valve does not work after the solenoid valve is energized
(2) Check the power wiring is re-wiring and connectors adverse → Connection
(3) Check the power supply voltage is within ± working range - → tone induced normal position range
(4) Coil yes or not desoldering →re-soldering
(5) Replace the coil shorted coil
(6) Liquid viscosity is too large, the frequency is too high, and life has come to replace the product
