When tightening, be careful not to touch the glass ball of the spray head and the anti-splashing disk; do not twist the support arm of the spray head, otherwise it will deform the spray head and cause leakage.
Finally, screw the inner cover into the outer cover (special attention: because the inner cover and the bottom cover are welded with a low-temperature fusible alloy, the welding strength of the low-temperature fusible alloy is low, so it should be Take special care not to apply excessive force on the bottom cover, but slowly screw into the outer cover according to several points on the inner cover that are distributed according to the spiral.
Excessive force will cause the fusible alloy to break, and the bottom cover and inner cover will fall off. The special wrench produced by our factory should be used for installation. If the spray head cannot be sealed after installation, it is never allowed to install with an extended sleeve on the wrench. Check whether the pipe fitting is qualified). If the pipe fitting is unqualified, please replace or repair the pipe fitting thread before installation. If forced installation may cause damage to the nozzle.
