1, the installation is only in accordance with the equipment barrel arrow on the instructions of the water inlet direction connected to the pipeline. If the valve is mounted, there is an adjusting screw on the valve cover to adjust the length of the flushing time. ? If the valve body is buried, to remove the valve cover, the top of the spool should have hexagonal holes, is to adjust the time. ? Foot flush valve toilet with a tank of flushing equipment, especially the water tank with the outlet valve. (As shown below).
2, the installation of the first to drain the water to clean the pipeline in the iron miscellaneous son, in order to prevent damage to the sealant parts. First access to the toilet water shut off, in the toilet access to the location of the flush valve in the water pipe location to install a three-port connector, in the connector on one side of the flush valve in the toilet piping connected to the water in the installation of the mouth of the place to add a sealing rubber ring, in the installation of the time to pay attention to do not inlet in the water outlet to adjust the mess. (As shown below).
3, to be installed after the bathroom tile can be formally installed flush valve. Most of the flush valve is installed horizontally, the height of the squatting pit above the ground 1 - 1.2 meters is appropriate.

Hand-twisted flush valve how to repair, installation precautions:
1, indoor and outdoor connecting pipe flare must be with the shut-off valve connector threads are correct, by hand to tighten the nut, the connector threads are generally hand-twisted to go in more than 3 buttons before allowing the use of wrenches to tighten the nut (you can rub some freezer oil in the threaded parts to facilitate the (You can rub some freezing oil on the threaded part to facilitate the hand tightening of the nut.) If you only screw in 1 or 2 buttons, you must check the joint threads to see if there is any scratching or slipping.
2, air conditioning after the installation of the valve core and valve core nut must be installed in the valve body with a certain torque.
3, nut and connector threads hand-tightened, and then use a wrench for locking, when the nut is screwed full of all the teeth buckle, and then back to twist half a buckle teeth and then tighten the nut.
4, replacement of the shut-off valve, before welding down the shut-off valve, first drain the system inside the refrigerant, and then use a wet cloth will be wrapped shut-off valve valve, pay attention to the direction of the flame when welding, do not allow the flame on the valve body heating, so as to avoid damage to the sealing ring affected by the cause of the failure analysis.
5, in welding the new globe valve, in principle, require the globe valve into the water to weld, in special circumstances can be used to wrap the wet cloth method, do not allow welding operations in the case of non-cooling. ', 17/16'' and other markings, supporting the connection pipe copper nut should pay attention to the metric system corresponds to the use of household air conditioners with conical surface of the outer surface of the connection pipe copper nut all for the British nut.
7, in the welding shut-off valve cooling should pay attention to avoid water into the valve body.
