With the improvement of the quality of life, water purifiers have become more and more popular and have become an indispensable household appliance in our daily life. However, during the use of the water purifier, the filter element will gradually absorb impurities and pollutants in the water, resulting in a decrease in filtration effect, and may even cause secondary pollution. Therefore, regular replacement of the filter element is the key to maintaining the normal operation of the water purifier and the safety of the water quality. So, how to scientifically replace the filter element of the water purifier? Next, we will introduce in detail how to replace the filter element of the water purifier.
1. Close the electroplating ball valve and wait for about 10 minutes. (Decompress the system).
2. Unscrew the nut joint on the right side of the membrane shell with your hand or tool and pull out the water pipe.
3. Facing the machine, hold the membrane shell tightly with your left hand, and turn the tail end cover with your right hand. (If the rear activated carbon filter above the reverse osmosis membrane tube prevents this step from operating, it can be slightly shifted or pulled out entirely, and if it is pulled out entirely, additional tubing needs to be disassembled.) )
4. Close the ball valve of the pressure barrel, unscrew the nut joint above it by hand or tool, and lead the water pipe into an empty bucket or washing tank.
5. Hold the reverse osmosis membrane tube tightly with your left hand, and then clamp the old reverse osmosis membrane with pliers and pull it out of the membrane shell.
6. Open the envelope of the new reverse osmosis membrane and take it out.
7. Plug the newly opened reverse osmosis membrane into the reverse osmosis membrane tube until one end of the two small black "O" rings reaches the bottom end of the membrane shell.
8. Screw the membrane shell cover tightly in the same posture as opening the membrane shell cover.
9. If necessary, adjust the fitting in a clockwise (locking) direction so that it points to the rear of the machine.
10. Plug into the water pipe and tighten the joint nut. (Don't forget to put the plug on it).
11. Open the electroplating ball valve.
12. Let the machine run for more than two hours, so that the system enters the normal water-making state, and then connect the water pipe with the pressure barrel ball valve and open the pressure barrel ball valve. This completes the entire dressing process.
It is also worth noting that before replacing the water purifier filter element, the water source needs to be turned off first to avoid unexpected situations during the replacement process. Before removing the old filter, you need to open the casing of the water purifier. It is recommended to clean the inside of the water purifier to remove possible impurities and stains. During the installation of a new filter, attention needs to be paid to the orientation and position of the filter element to ensure that it can properly filter water.
How to judge whether to replace the filter element of the water purifier.
1. The effluent flow is very small and cannot meet the normal needs (indicating that the filter element is blocked, and the filter element should be cleaned in order to restore the normal flow), and the flow rate is still very small after cleaning and cannot meet the needs;
2. The taste of the effluent decreases and the taste is close to that of tap water, that is, the chlorine taste of tap water cannot be removed, indicating that the activated carbon filter element has been adsorbed and saturated, and the activated carbon is invalid;
3. The softening function cannot be restored after the softening core is regenerated or the softening effect does not meet the requirements;
4. The service life of the filter element reaches two years. (The filter replacement cycle of the household water purifier is determined according to the quality of the filter element, the quality of the filtered water, and the amount of water filtered.) It is usually recommended to change it every six months to every year).
In order to keep the water purifier in good condition, prolong its service life and ensure the safety of water quality, we need to regularly care for and maintain the water purifier. For specific maintenance and maintenance methods, please refer to the instruction manual of the water purifier or consult professional after-sales service personnel. In general, the filter cartridge needs to be replaced every once in a while, depending on the local water quality and the use of the water purifier. At the same time, it is also necessary to regularly clean the casing and internal parts of the water purifier to ensure that it is operating properly and maintaining good filtration effect.
