        The solenoid valve installation instructions

        1, before the installation of the first pipe, the impurities rinse.
        2, if the water tower water supply, please choose with the water pressure matching solenoid valve, so that the solenoid valve can not be on the water or flow is too small.
        3, check the solenoid valve logo voltage and control power output voltage is consistent, check the filter is complete, the valve parts are not damaged. The flow direction is consistent with the direction of the arrow of the solenoid valve.
        4, the solenoid valve should be installed in the room easy to repair and avoid other associated loss of the area, pay attention to frost, sunscreen, to prevent the valve body frost aging, shorten the service life. The coil is facing up during installation.
        5, prohibit the use of wrenches and other tools on the coil and plastic parts, solenoid valve at both ends of the interface piping should be kept in the same line, not two interfaces up and down when the forced installation, to ensure that the solenoid valve is not damaged in the installation; The installed solenoid valve is not subject to dislocation torque.
        6, after installation, power detection.
        7, the emergence of defective solenoid valve, with stickers affixed fault tag, and indicate the location, time, fault phenomenon, handling and other factors, so that manufacturers quality screening and improvement.
        8, if there is abnormal installation, the use of the resulting failure and loss, does not belong to the scope of three packs of manufacturers.
        Second, the basic failure and troubleshooting methods
        1, the solenoid valve can not open
        cause of issue
        Inspection Method
        solution
        1) Poor wiring
        Check the contact
        Re-connect the line
        2) Whether the coil is normally energized Multimeter value resistance Replace the coil or solenoid valve
        3) the working voltage is not normal
        Measuring the working voltage
        Replace the input power to make it normal
        4) small water pressure less than 0.2Mpa to open the faucet is estimated to install the booster pump or replace the low pressure solenoid valve
        5) Filter the plug to watch the regular cleaning filter
        6) foreign body plug the valve flap hole open the barrel visually clean the hole to open and check the filter
        7) water pressure higher than 0.8Mpa open the faucet is estimated to install the pressure relief valve or to enhance the working voltage (by 10%)
        8) the direction of the inlet and outlet anti-installed visual re-installed correctly
        9) other replacement solenoid valve and paste the fault label
        2, the solenoid valve can not be closed
        cause of issue
        Detection method
        solution
        1) Power supply Always turn on the multimeter to measure replacement or service power
        2) foreign body plug valve flap or valve mouth open the coil visual inspection to make the hole smooth and check the filter
        3) moving the bottom of the core rubber pieces off the coil re-installed rubber re-installed
        4) rubber mold broken or peel off the coil re-installed the rubber membrane re-installed
        5) Replace the solenoid valve and paste the fault label
        3, back to the leak
        cause of issue
        Detection method
        solution
        1) Check the diaphragm back or peel off the back cover to re-install the check box
        2) foreign body plug the valve mouth open the back cover visual cleaning foreign body, re-check
        3) other replacement solenoid valve and paste the fault label
        4, small flow
        cause of issue
        Detection method
        solution
        1) foreign body plug valve flap or valve mouth open the coil visual cleaning to make the hole open
        2) filter plug the visual cleaning filter
        3) other replacement solenoid valve and paste the fault label
        5, low water leakage
        cause of issue
        Detection method
        solution
        1) There are water masonry and dirt in the valve chamber to open the coil visually clean the rubber diaphragm and the dirt inside the valve chamber
        2) Replace the solenoid valve and paste the fault label
        6. pipe or other parts of the valve body leakage
        cause of issue
        Detection method
        solution
        1) Transport
        Damaged or Frozen Rupture Visual Replacement solenoid valve affixed with a fault label and notice correct
        Installation, the solenoid valve installed in the room or to strengthen the insulation
        2) Replace the solenoid valve and paste the fault label
