What are the installation steps of the water purifier? How is it installed? I bought a water purifier at home now, and I don't know how to install it. Water purifier 1 installation steps: install all filter elements (except RO membrane packed in vacuum seal) in place. 2. Turn off the tap water source, connect the stainless steel tee and the water inlet ball valve to the tap water pipe, and then connect the water inlet ball valve to the water purifier with a bifurcated hose; The pure water port is connected with the gooseneck faucet; The water storage pressure barrel is in the state of valve opening and closing: closed and connected with the host computer; The sewage outlet is connected to the second branch pipe and to the floor drain. (Don't install RO membrane, and don't connect the water dispenser. ) 3: After all pipes and filter elements (except RO membrane) are installed, turn on tap water and water inlet ball valve to supply water and plug in electricity. At the same time, turn on the gooseneck pure water faucet, and flush the installed filter element for about 20 minutes until there is no black water flowing out, and stop the water supply and power supply. 4. Install reverse osmosis membrane. One end of RO membrane with large black sealing ring is on the outer side of membrane shell cover, and the other end with two small black sealing rings is inserted into the pure water hole in the middle. When installing the RO membrane, be sure to pay attention to the fact that the position of the RO membrane cannot be reversed, and the RO membrane shell cover cannot be forcibly inserted or covered. Failure to cover the membrane shell means that the RO membrane is not installed properly and needs to be reinstalled. 5: Turn on the water and electricity, turn on the gooseneck pure water faucet at the same time (the ball valve of the water storage pressure barrel is closed), rinse the RO membrane for about 40 minutes, and then stop the water supply and power supply. 6. Turn on the water and electricity, turn on the switch of the pressure storage barrel and turn off the gooseneck pure water faucet at the same time. When the pressure storage barrel is full of water, stop the water supply and power supply, and put the first barrel of water in the pressure storage barrel away from drinking. If not, you can refer to the above methods, or find a professional master. Typing is not easy, such as adoption.
