2. Unscrew the nut joint on the right side of the membrane shell with your hand or tool and pull out the water pipe.

Close the pressure bucket ball valve, unscrew the nut fitting above it by hand or tool, and direct the hose into an empty bucket or sink.

3. Hold the reverse osmosis membrane tube tightly with your hands, and then clamp the old reverse osmosis membrane with pliers (or special tools), and pull it out of the membrane shell forcefully.

4. Open the envelope of the new reverse osmosis membrane and take it out.

5. Plug the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until one end of the two small black "O" rings is pushed up to the bottom end of the membrane shell.

6. Screw the membrane shell cover tightly in the opposite direction of the membrane shell cover.

7. Plug into the water pipe and tighten the joint nut. (Don't forget to put the plug, except for push-in fittings).

Then check whether the white plastic gasket inside the filter bottle cap and the black gasket outside the mouth of the filter bottle are tightened, and tighten them in time if they are loose. Then you can observe your own PP color through the transparent front to determine whether your PP cotton needs to be replaced, if the PP cotton at home is more serious, you can replace it, if there is a particularly serious situation, it must be replaced, and it cannot be replaced.

It must be noted that the water valve of the machine is closed (if there is no three-way ball valve on the water purifier, the main water valve at home needs to be closed), and then the faucet is opened to empty the water in the water purifier; Finally, fill the filter bottle with more than half a bottle of tap water, put the filter bottle back into the filter bottle cap, and tighten it so that it will not leak. PS softening filter element and RO membrane are generally replaced once every 2 years, PP cotton for 6 months, EM-X ceramic filter element for 5 years, and central control fiber ultrafiltration membrane and activated carbon need to be replaced once a year.
